<p class=MsoPlainText>Welcome to ZoneMinder, the all-in-one Linux GPL'd
security camera solution.</p>
<p class=MsoPlainText>A while back my garage was burgled and all my power tools
were stolen! I realised shortly after that if I'd just had a camera overlooking
the door then at least I'd have know exactly when and who did the dirty deed.
And so ZoneMinder was born. It's still relatively new but hopefully it has
developed to be something that can be genuinely useful and prevent similar
incidents or even perhaps bring some perpetrators to justice.</p>
<p class=MsoPlainText>ZoneMinder is designed around a series of independent
components that only function when necessary limiting any wasted resource and
maximising the efficiency of your machine. A fairly ancient Pentium II PC
should be able to track one camera per device at up to 25 frames per second
with this dropping by half approximately for each additional camera on the same
device. Additional cameras on other devices do not interact so can maintain
this frame rate. Even monitoring several cameras still will not overload the
CPU as frame processing is designed to synchronise with capture and not stall
it.</p>
<p class=MsoPlainText>As well as being fast ZoneMinder is designed to be
friendly and even more than that, actually useful. As well as the fast video
interface core it also comes with a user friendly and comprehensive PHP based
web interface allowing you to control and monitor your cameras from home or
even at work or on the road. It supports variable web capabilities based on
available bandwidth. The web interface also allows you to view events that your
cameras have captured and archive them or review them time and again, or delete
the ones you no longer wish to keep. The web pages directly interact with the
core daemons ensuring full co-operation at all times. ZoneMinder can even be
installed as a system service ensuring it is right there if your computer has
to reboot for any reason.</p>
<p class=MsoPlainText>The core of ZoneMinder is the capture and analysis of
images and there is a highly configurable set of parameters that allow you to
ensure that you can eliminate false positives whilst ensuring that anything you
don't want to miss will be captured and saved. ZoneMinder allows you to define
a set of 'zones' for each camera of varying sensitivity and functionality. This
allows you to eliminate regions that you don't wish to track or define areas
that will alarm if various thresholds are exceeded in conjunction with other
zones.</p>
<p class=MsoPlainText>ZoneMinder is fresh off the keyboard and so comes with no
warranty whatsoever, please try it, send your feedback and if you get anything
useful out of it let me know.</p>
<p class=MsoPlainText>ZoneMinder is free but if you do get ZoneMinder up and
running and find it useful then please feel free to visit <span
class=Internetlink><a href="http://www.zoneminder.com/donate.html">http://www.zoneminder.com/donate.html</a></span>
where <b><span style='color:red'>any donations will be appreciated</span></b>
and will help to fund future improvements to ZoneMinder. This would be
especially relevant if you use ZoneMinder as part of your business, or to
protect your property.</p>

</span></u></b>
<h1><a name="_Toc125113483"></a><a name="_Toc124931626"><span style='text-decoration:

</span></span><u>Requirements</u></a></h1>
<p class=MsoPlainText>ZoneMinder needs a couple of things to work. Ordinarily
the &#8216;configure&#8217; script will check for the presence of required (and
optional) components but it is useful to be prepared beforehand.</p>
<p class=MsoPlainText>Firstly, it uses MySQL so you'll need that. In order to
compile you need to make sure you have a development installation and not just
a runtime; this is because it needs to use the MySQL header files. If you are
running an RPM based distribution then it&#8217;s probably worth installing all
the pure mysql rpm files to be sure you have the right ones.</p>
<p class=MsoPlainText>Next it does things with JPEGs so you'll need at least
libjpeg.a which I think come as standard nowadays with most distributions.
Users have reported varying degrees of success with other jpeg libraries such
as jpeg-mmx but these are not officially supported. If you plan to use network
cameras then the Perl Compatible Regular Expression library (libpcre.a) can
prove useful but is not always essential. ZoneMinder also uses the netpbm
utilities in a very limited way to generate thumbnails under certain
circumstances though this can be modified.</p>
<p class=MsoPlainText>ZoneMinder can generate MPEG videos if necessary, for
this you'll need either ffmpeg (recommended) or the Berkeley MPEG encoder
(mpeg_encode). If you don't have either, don't worry, as the options will be
hidden and you'll not really miss too much. Some of the authentication uses
openssl MD5 functions, if you get a grumble about these during configuration
all it will mean is that authentication won&#8217;t be used for streaming. The
web interface uses PHP and so you need that in your apache or other web server
as well, make sure MySQL support is available either statically or as a module.
There are also various perl modules that you may need that vary depending on
which options you choose on installation, for more details see later in this
document.</p>
<p class=MsoPlainText>Finally, there is quite a bit of image streaming in the
package. So if you don't have FireFox<6F> or another browser that supports image
streaming natively I recommend you get the excellent Cambozola java applet from
<span class=Internetlink>http://www.charliemouse.com/code/cambozola/</span>
which will let you view the image stream in Internet Explorer and others.
Otherwise you're limited to just refreshing still images or mpeg based streams,
if you have compatible plugins.</p>
<p class=MsoPlainText>Hardware-wise, ZoneMinder has been used with various
video and USB cameras with the V4L interface. It will also work with most
Network or IP cameras. I don't have a lot of cameras myself so I've not had
change to test it with a huge range personally however there is a list of
devices that are definitely known to work on the web site. Please let me know
if your camera works and is not listed. You do need to have Video4Linux
installed. I've not got too many machines so I've only really used it on
various RedHat/Fedora distributions, which seem to have everything there by
default I think. SlackWare does need a bit more tinkering than other
distributions; there is a document on the web site describing what users have
had to do to get it working. Please give me feedback on other distributions not
listed on the site.</p>

<h1><a name="DDE_LINK2"></a><a name="_Toc125113484"><span style='text-decoration:

</span></span><u>Components</u></a></h1>
<p class=MsoPlainText>ZoneMinder is not a single monolithic application but is
formed from several components. These components primarily include executable
compiled binaries which do the main video processing work, perl scripts which
usually perform helper and/or external interface tasks and php web scripts
which are used for the web interface.</p>
<p class=MsoPlainText>A brief description of each of the principle components
follows.</p>
<p class=MsoPlainText><b>zmc</b> &#8211; This is the ZoneMinder Capture daemon.
This binary's job is to sit on a video device and suck frames off it as fast as
possible, this should run at more or less constant speed.</p>
<p class=MsoPlainText><b>zma</b> &#8211; This is the ZoneMinder Analysis
daemon. This is the component that goes through the captured frames and checks
them for motion which might generate an alarm or event. It generally keeps up
with the Capture daemon but if very busy may skip some frames to prevent it
falling behind.</p>
<p class=MsoPlainText><b>zmf</b> &#8211; This is the ZoneMinder Frame daemon.
This is an optional daemon that can run in concert with the Analysis daemon and
whose function it is to actually write captured frames to disk. This frees up
the Analysis daemon to do more analysis (!) and so keep up with the Capture
daemon better. If it isn&#8217;t running or dies then the Analysis daemon just
writes them itself.</p>
<p class=MsoPlainText><b>zms</b> &#8211; This is the ZoneMinder Streaming
server. The web interface connects with this to get real-time or historical
streamed images. It runs only when a live monitor stream or event stream is
actually being viewed and dies when the event finishes or the associate web
page is closed. If you find you have several zms processes running when nothing
is being viewed then it is likely you need a patch for apache (see the
Troubleshooting section). A non-parsed header version of zms, called nph-zms,
is also installed and may be used instead depending on your web server
configuration.</p>
<p class=MsoPlainText><b>zmu</b> &#8211; This is the ZoneMinder Utility. It's
basically a handy command line interface to several useful functions.
It&#8217;s not really meant to be used by anyone except the web page (there's
only limited 'help' in it so far) but can be if necessary, especially for
debugging video problems.</p>
<p class=MsoPlainText><b>zmfix</b> &#8211; This is a small binary that exists
only to ensure that the video device files can be read by the main capture daemons.
It is often the case that these device files are set to be accessible by root
only on boot. This binary runs setuid and ensures that they have appropriate
permissions. This is not a daemon and runs only on system start and then exits.</p>
<p class=MsoPlainText>As well as this there are the web PHP files in the web
directory and some perl scripts in the scripts directory. These scripts all
have some configuration at the top of the files which should be viewed and
amended if necessary and are as follows.</p>
<p class=MsoPlainText><b>zmpkg.pl</b> &#8211; This is the ZoneMinder Package
Control script. This is used by the web interface and service scripts to
control the execution of the system as a whole.</p>
<p class=MsoPlainText><b>zmdc.pl</b> &#8211; This is the ZoneMinder Daemon
Control script. This is used by the web interface and the zmpkg.pl script to
control and maintain the execution of the capture and analysis daemons, amongst
others. You should not need to run this script yourself.</p>
<p class=MsoPlainText><b>zmfilter.pl</b> &#8211; This script controls the
execution of saved filters and will be started and stopped by the web interface
based on whether there are filters that have been defined to be autonomous.
This script is also responsible for the automatic uploading of events to a 3rd
party server.</p>
<p class=MsoPlainText><b>zmaudit.pl</b> &#8211; This script is used to check
the consistency of the event file system and database. It can delete orphaned
events, i.e. ones that appear in one location and not the other as well as
checking that all the various event related tables are in line. It can be run
interactively or in batch mode either from the command line or a cron job or
similar. In the zmconfig.pl there is an option to specify fast event deletes
where the web interface only deletes the event entry from the database itself.
If this is set then it is this script that tidies up the rest.</p>
<p class=MsoPlainText><b>zmwatch.pl</b> &#8211; This is a simple script purely
designed to keep an eye on the capture daemons and restart them if they lockup.
It has been known for sync problems in the video drivers to cause this so this
script makes sure that nothing important gets missed.</p>
<p class=MsoPlainText><b>zmupdate.pl</b> &#8211; Currently this script is
responsible for checking whether a new version of ZoneMinder is available and
other miscellaneous actions related to upgrades and migrations. It is also
intended to be a &#8216;one stop shop&#8217; for any upgrades and will execute
everything necessary to update your installation to a new version.</p>
<p class=MsoPlainText><b>zmvideo.pl</b> &#8211; This script is used from the
web interface to generate video files in various formats in a common way. You
can also use it from the command line in certain circumstances but this is not
usually necessary.</p>
<p class=MsoPlainText><b>zmx10.pl</b> &#8211; This is an optional script that
can be used to initiate and monitor X10 Home Automation style events and
interface with an alarm system either by the generation of X10 signals on
ZoneMinder events or by initiating ZoneMinder monitoring and capture on receipt
of X10 signals from elsewhere, for instance the triggering of an X10 PIR. For
example I have several cameras that don&#8217;t do motion detection until I arm
my alarm system whereupon they switch to active mode when an X10 signal is generated
by the alarm system and received by ZoneMinder.</p>
<p class=MsoPlainText><b>zmtrigger.pl</b> &#8211; This is an optional script
that is a more generic solution to external triggering of alarms. It can handle
external connections via either internet socket, unix socket or file/device
interfaces. You can either use it &#8216;as is&#8217; if you can interface with
the existing format, or override connections and channels to customise it to
your needs. The format of triggers used by zmtrigger.pl is as follows
&#8220;&lt;id&gt;|&lt;action&gt;|&lt;score&gt;|&lt;cause&gt;|&lt;text&gt;|&lt;showtext&gt;&#8221;
where</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>'action' is 'on', 'off', 'cancel' or &#8216;show&#8217; where
'on' forces an alarm condition on, 'off' forces an alarm condition off and
'cancel' negates the previous 'on' or 'off'. The &#8216;show&#8217; action
merely updates some auxiliary text which can optionally be displayed in the
images captured by the monitor. Ordinarily you would use 'on' and 'cancel',
'off' would tend to be used to suppress motion based events. Additionally 'on'
and 'off' can take an additional time offset, e.g. on+20 which automatically
'cancel's the previous action after that number of seconds.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>'score' is the score given to the alarm, usually to indicate it's
importance. For 'on' triggers it should be non-zero, otherwise it should be
zero.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>'cause' is a 32 char max string indicating the reason for, or
source of the alarm e.g. 'Relay 1 open'. This is saved in the
&#8216;Cause&#8217; field of the event. Ignored for 'off' or 'cancel' messages</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>'text' is a 256 char max additional info field, which is saved in
the &#8216;Description&#8217; field of an event. Ignored for 'off' or 'cancel'
messages.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>&#8216;showtext&#8217; is up to 32 characters of text that can be
displayed in the timestamp that is added to images. The &#8216;show&#8217;
action is designed to update this text without affecting alarms but the text is
updated, if present, for any of the actions. This is designed to allow external
input to appear on the images captured, for instance temperature or personnel
identity etc.</p>
<p class=MsoPlainText>Note that multiple messages can be sent at once and
should be LF or CRLF delimited. This script is not necessarily intended to be a
solution in itself, but is intended to be used as &#8216;glue&#8217; to help
ZoneMinder interface with other systems.</p>
<p class=MsoPlainText><b>zmcontrol-*.pl</b> &#8211; These are a set of example
scripts which can be used to control Pan/Tilt/Zoom class cameras. Each script
converts a set of standard parameters used for camera control into the actual
protocol commands sent to the camera. If you are using a camera control
protocol that is not in the shipped list then you will have to create a similar
script though it can be created entirely separately from ZoneMinder and does
not need to named as these scripts are. Although the scripts are used to action
commands originated from the web interface they can also be used directly or
from other programs or scripts, for instance to implement periodic scanning to
different presets.</p>
<p class=MsoPlainText><b>zmtrack.pl</b> &#8211; This script is used to manage
the experimental motion tracking feature. It is responsible for detecting that
an alarm is taking place and moving the camera to point to the alarmed
location, and then subsequently returning it to a defined standby location. As
well as moving the camera it also controls when motion detection is suspended
and restored so that the action of the camera tracking does not trigger endless
further alarms which are not justified.</p>
<p class=MsoPlainText><b>zm</b> &#8211; This is the (optional) ZoneMinder init
script, see below for details.</p>
<p class=MsoPlainText>Finally, there are also a number of ZoneMinder perl
modules included. These are used by the scripts above, but can also be used by
your own or 3<sup>rd</sup> party scripts. Full documentation for most modules
is available in &#8216;pod&#8217; form via &#8216;perldoc&#8217; but the
general purpose of each module is as follows.</p>
<p class=MsoPlainText><b>ZoneMinder.pm</b> &#8211; This is a general ZoneMinder
container module. It includes the Base.pm, Config.pm Debug.pm, Database.pm, and
SharedMem.pm modules described below. It also exports all of their symbols by
default. If you use the other modules directly you have request which symbol
tags to import.</p>
<p class=MsoPlainText><b>ZoneMinder/Base.pm</b> &#8211; This is the base
ZoneMinder perl module. It contains only simple data such as version
information. It is included by all other ZoneMinder perl modules</p>
<p class=MsoPlainText><b>ZoneMinder/Config.pm</b> &#8211; This module imports
the ZoneMinder configuration from the database.</p>
<p class=MsoPlainText><b>ZoneMinder/Debug. pm</b> &#8211; This module contains
the defined Debug and Error functions etc, that are used by scripts to produce
diagnostic information in a standard format.</p>
<p class=MsoPlainText><b>ZoneMinder/Database.pm</b> &#8211; This module
contains database access definitions and functions. Currently not a lot is in
this module but it is included as a placeholder for future development.</p>
<p class=MsoPlainText><b>ZoneMinder/SharedMem.pm</b> &#8211; This module
contains standard shared memory access functions. These can be used to access
the current state of monitors etc as well as issuing commands to the monitors
to switch things on and off. This module effectively provides a ZoneMinder API.</p>
<p class=MsoPlainText><b>ZoneMinder/ConfigAdmin.pm</b> &#8211; This module is a
specialised module that contains the definition, and other information, about
the various configuration options. It is not intended for use by 3rd parties.</p>
<p class=MsoPlainText><b>ZoneMinder/Trigger/*.pm</b> &#8211; These modules
contain definitions of trigger channels and connections used by the
zmtrigger.pl script. Although they can be used &#8216;as is&#8217;, they are
really intended as examples that can be customised or specialised for different
interfaces. Contributed modules for new channels or connections will be
welcomed and included in future versions of ZoneMinder.</p>

</span></span><u>Building</u></a></h1>
<p class=MsoPlainText>To build ZoneMinder the first thing you need to do is run
the included configure script to define some initial configuration. If you are
happy with the default settings for the database host
(&#8216;localhost&#8217;), name (&#8216;zm&#8217;), user (&#8216;zmuser&#8217;)
and password (&#8216;zmpass&#8217;) then you can just type</p>
<p class=Command>./configure --with-webdir=&lt;your web directory&gt;
--with-cgidir=&lt;your cgi directory&gt;</p>
<p class=MsoPlainText>where <i>--with-webdir</i> is the directory to which you
want to install the PHP files, and <i>--with-cgidir</i> is the directory to
which you want to install CGI files. These directories could be <i>/var/www/html/zm</i>
and <i>/var/www/cgi-bin</i> for example.</p>
<p class=MsoPlainText>If you want to override any of the default database
values then you can append them to the configure command, for example to use a
database password of &#8216;zmnewpass&#8217; do</p>
<p class=Command>./configure --with-webdir=&lt;your web directory&gt;
--with-cgidir=&lt;your cgi directory&gt; ZM_DB_PASS=zmnewpass</p>
<p class=MsoPlainText>and so on. The values you can use are ZM_DB_HOST,
ZM_DB_NAME, ZM_DB_USER and ZM_DB_PASS. Other than the database name, which is
substituted into the database creation script, these values can easily be
changed after this step.</p>
<p class=MsoPlainText>If the script cannot find your MySQL installation, for
instance if it is installed in an unusual location, then --<i>with-mysql</i>
identifies the root directory where you have installed it, usually /usr.</p>
<p class=MsoPlainText>If you want to use real MPEG based streaming you will
need to have built and installed the ffmpeg tools. You can then also use <i>&#8211;with-ffmpeg=&lt;path
to ffmpeg root&gt;</i> to help configure find it if it&#8217;s not installed in
a default location. Note, you have to make sure you have installed the ffmpeg
headers and libraries (<i>make installlib</i>) as well as the binaries (<i>make
install</i>), or a development package with them in.</p>
<p class=MsoPlainText>If you have built ffmpeg with any additional options
which require extra libraries in the link stage then you can use <i>--with-extralibs</i>
to pass these libraries to the configure script, to prevent unresolved dependencies.
Otherwise ignore this option.</p>
<p class=MsoPlainText>If you are on a 64 bit system you may find that the <i>&#8211;with-libarch
</i>option helps you correctly define your library paths.</p>
<p class=MsoPlainText>There are also two further parameters you can add if your
web user and group are not both 'apache'. These are <i>--with-webuser</i> and <i>--with-webgroup</i>.</p>
<p class=MsoPlainText>Type</p>
<p class=Command>./configure &#8211;help</p>
<p class=MsoPlainText>for details on these, and other, options.</p>
<p class=MsoPlainText>Now you can just type <i>'make'</i> to do the build. The
first time you run this you may get a warning about a Makefile being rebuilt in
the scripts directory, and make will terminate. This is normal and you can just
rerun make to complete the build.</p>
<b><u><span style='font-size:14.0pt;font-family:Arial'><br clear=all

</span></u></b>
<h1><a name="_Toc125113486"><span style='text-decoration:none'>5.<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span></span><u>Installation</u></a></h1>
<p class=MsoPlainText>For a new installation the next thing you will need to do
is create your database and database users. So type the commands as follows,</p>
<p class=Command>mysql mysql &lt; db/zm_create.sql</p>
<p class=Command>mysql mysql</p>
<p class=Command>grant select,insert,update,delete on &lt;database name&gt;.*
to '&lt;database user&gt;'@localhost identified by '&lt;database password&gt;';</p>
<p class=Command>quit</p>
<p class=Command>mysqladmin reload</p>
<p class=MsoPlainText>You may need to supply a username and password to the
mysql commands in the first place to give yourself sufficient privileges to
perform the required commands. If you want to host your database on a different
machine than that which ZoneMinder is running on then you will need to perform
this step on the remote machine and reference the ZoneMinder machine instead of
localhost. If you are running remote databases you probably already know all
this, if you are not then don&#8217;t worry about it!</p>
<p class=MsoPlainText>At this stage typing</p>
<p class=Command>make install</p>
<p class=MsoPlainText>will install everything to the desired locations, you may
need to su to root first though to give yourself adequate permissions. The
installation routine will copy the binaries and scripts to your chosen install
location, usually /usr/local/bin and then move zms (and nph-zms) to your
cgi-bin area. It will then copy the web files to your chosen directory and
ensure they have the right permissions, and install the ZoneMinder perl modules
in the standard perl locations. It will also install a copy of the zm.conf file
(generated by configure) to your system configuration area (e.g.
/usr/local/etc). Finally it tries to link zm.php to index.php but will not
overwrite an existing file if it already exists.</p>
<p class=MsoPlainText>The 'zm' script does not get installed automatically as
it is not necessary for the operation of the ZoneMinder setup per se and is not
necessarily likely to work correctly for distributions other than those from
the RedHat or Fedora families. However if you want to ensure that ZoneMinder is
started on reboot etc copy it to your init.d directory, usually something like
/etc/rc.d/init.d or /etc/inid.d and then add it by doing</p>
<p class=MsoPlainText><i>chkconfig --add zm</i></p>
<p class=MsoPlainText>or similar command for your distribution. ZoneMinder will
then start up when your machine reboots and can be controlled (by the root
user) by doing <i>'service zm start'</i> or <i>'service zm stop'</i> etc. You
may need to use the <i>&#8216;&#8212;levels</i>&#8217; parameter to chkconfig
to ensure that ZoneMinder is started when you need it to.</p>
<p class=MsoPlainText>If you do this you should find that you have files named
S99zm in some of the /etc/rc<i>X</i>.d directories and K99zm in some of the
others. The S99zm files are used for starting up ZoneMinder on system boot and
the K99zm ones are used to close it on system shutdown. The <i>99</i> part is a
priority, which may run from 0 to 99 and indicates where in the startup and
shutdown sequences that ZoneMinder should start or stop. So S99zm means that
ZoneMinder should be one of the last things to startup, which is good as it
needs things like the database to be running first.</p>
<p class=MsoPlainText>However, by the same token, the K99zm scripts indicate
that ZoneMinder should be one of the last things to shut down, which is bad, as
by then the database etc will have gone away. So for tidiness you should rename
any K99zm files to K00zm to indicate that ZoneMinder should be one of the first
elements to stop. This way you will avoid any nasty messages on your console
about the database having gone away and also will give ZoneMinder chance to
shutdown in a controlled manner without introducing any corruption.</p>
<p class=MsoPlainText>As mentioned above, this script is for Redhat, and
related, distributions only. I would be grateful for any similar scripts for
other distributions so if you know of one, or create one, then please send it
to me.</p>
<p class=MsoPlainText>If you are running a distribution which doesn&#8217;t
support the zm script, or if you just prefer more direct control, you can now
start ZoneMinder by typing</p>
<p class=Command>zmpkg.pl start</p>
<p class=MsoPlainText>which, after a few seconds, should return without error.
You can subsequently stop and restart everything by changing the
&#8216;start&#8217; parameter to &#8216;stop&#8217; or &#8216;restart&#8217;.</p>
<p class=MsoPlainText>Now fire up your web browser, point it at your zm.php and
off you go.</p>
<p class=MsoPlainText>Note, if you ever need to uninstall ZoneMinder you can do
this by simply typing</p>
<p class=Command>make uninstall</p>
<p class=MsoPlainText>though as with installation you may need to change user
to have sufficient privileges. This will remove all installed files, however
you will need to manually remove any databases you have created.</p>

<p class=MsoPlainText>If you are upgrading from a previous version of
ZoneMinder you should follow the Building instructions above. Before proceeding, ensure that any previous version of ZoneMinder has been stopped, then type</p>
<p class=Command>make install</p>
<p class=MsoPlainText>to install the binaries, scripts, modules, web and
configuration files.</p>
<p class=MsoPlainText>The next step in an upgrade is to run the zmupgrade.pl
script to make any changes to the database or file system required by the new
version. Ordinarily you can run this from your ZoneMinder build directory by
doing</p>
<p class=MsoPlainText><i>zmupdate.pl &#8211;version=&lt;from version&gt;
[--user=&lt;database user&gt; --pass=&lt;database password&gt;]</i></p>
<p class=MsoPlainText>where <i>&#8216;from version&#8217;</i> relates to the
version of ZM you are upgrading from, 1.21.1 for example, and not the version
you are upgrading to. All updates from that version onwards will be applied;
however zmupdate.pl will only work with upgrades from 1.19.0 onwards. The
&#8216;user&#8217; and &#8216;pass&#8217; options allow you to specify a
database user and password with sufficient privilege to &#8216;alter&#8217; the
structure of the database. This is not necessarily the database user you use
for ZoneMinder.</p>
<p class=MsoPlainText>The update script will offer you the chance to make a
database backup before making any changes. You can use this to restore your
database if the upgrade fails or if you simply wish to roll back in the future.
Be aware that if you have a lot of entries in your database and/or limited disk
space doing a backup may not be feasible or even work. Also the backup only
applies to the database and will not save any images or other event detail
saved on disk. If successful the backup will be saved in the current directory
and will be named <i>&lt;database name&gt;-&lt;from version&gt;.dump</i>. Any
previous backups of the same name will be overwritten without warning. The
backup file is in the form of a simple sql script and can be used to restore
the database simply by typing</p>
<p class=Command>mysql &lt; zm-1.21.4.dump </p>
<p class=MsoPlainText>for example.</p>
<p class=MsoPlainText>After having done any backup, the database upgrade will
be applied. Check that this is successful before continuing.</p>
<p class=MsoPlainText>Once the upgrade process is complete, you can then
restart ZoneMinder using the zmpkg.pl script or using the service control
commands for your distribution. You should check /var/log/messages and the
other ZoneMinder logs for the first few minutes to ensure that everything comes
back up successfully.</p>

<p class=MsoPlainText>What you see now (and subsequently) is the initial view
that appears when running in non-authenticated mode. Authentication is an
option that lets you specify whether anyone that goes to the ZoneMinder web
pages must log themselves in, in order to be given permissions to perform
certain tasks. Running in authenticated mode is recommended if your system is
open to the internet at all. During installation a fully privileged user
&#8216;admin&#8217; has been created with a password also of
&#8216;admin&#8217;. If you are using authentication you should change this
password as soon as possible.</p>
<p class=MsoPlainText>Once you&#8217;ve logged in, or if you are running in
un-authenticated mode, you will now see the ZoneMinder Console window. This
will resize itself to avoid being too intrusive on your desktop. Along the top
there are several informational entries like the time of the last update and
the current server load. There will also be an indication of the system state
which will probably say &#8216;stopped&#8217; to begin with. This is a link
that you can click on to control the ZoneMinder system as a whole.</p>
<p class=MsoPlainText>Below that are various other links including one
detailing the current user (in authenticated mode only) and one allowing you to
configure your bandwidth. This last one enables you to optimise your settings
depending on where you are, the actual values relating to this are defined in
the options. If you are using a browser on the same machine or network then
choose high, over a cable or DSL link maybe choose medium and over a dialup
choose low. You can experiment to see which is best. This setting is retained
on a per machine basis with a persistent cookie. Also on this line are a number
of other links that will be covered below.</p>
<p class=MsoPlainText>Please bear in mind that from here on the descriptions of
the web pages are based on what you will see if you are running as a fully
authenticated user. If you are running in un-authenticated mode or as a less
privileged user then some elements may not be shown or will be disabled.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Defining Monitors</a></h2>
<p class=MsoPlainText>To use ZoneMinder properly you need to define at least
one Monitor. Essentially, a monitor is associated with a camera and can
continually check it for motion detection and such like. So, next click 'Add
New Monitor' to bring up the dialog. You will see a bunch of things you have to
fill in.</p>
<p class=MsoPlainText>To help you get started on the video configuration the
best thing is to use a tool like 'xawtv' (<span class=Internetlink><a
href="http://bytesex.org/xawtv/">http://bytesex.org/xawtv/</a></span>) to get a
picture you're happy with, and to check your camera works. Please note that
just because you can see a video stream in these tools does not necessarily
guarantee that your camera will work with ZoneMinder. This is because most
tools just &#8216;map&#8217; the video image through onto screen memory
transparently without intercepting it, whereas ZoneMinder needs to capture the
image and, usually, inspect it. This is called frame grabbing and to check it
you should use the facility in xawtv, or other tool, to capture either one or
more still images or possibly a movie. If this works and the images or movie
are not garbage then the chances are that ZoneMinder will work fine also.</p>
<p class=MsoPlainText>Once you have validated your camera run 'zmu -d
&lt;device_path&gt; -q -v' to get a dump of the settings (note, you will have
to additionally supply a username and password to zmu if you are running in
authenticated mode). You can then enter these values into the video related
options of the monitor configuration panel. The 'device_path' referred to here
is the path to your video device file, for instance /dev/video0 etc. If 'zmu'
gives you an error related to permissions run 'zmfix -a' to make sure you can
access all the video devices.</p>
<p class=MsoPlainText>There are a small number of camera setups that ZoneMinder
knows about and which can be accessed by clicking on the &#8216;Presets&#8217;
link. Selecting one of the presets will fill in the monitor configuration with
appropriate values but you will still need to enter others and confirm the
preset settings.</p>
<p class=MsoPlainText>The options are divided into a set of tabs to make it
easier to edit. You do not have to &#8216;save&#8217; to change to different
tab so you can make all the changes you require and then click
&#8216;Save&#8217; at the end. The individual option are explained in a little
more detail below,</p>
<p class=MonitorTab>&#8216;Monitor&#8217; Tab</p>
<p class=MonitorOption><b>Name</b> &#8211; The name for your monitor. This
should be made up of alphanumeric characters (a-z,A-Z,0-9) and hyphen (-) and
underscore(_) only. Whitespace is not allowed.</p>
<p class=MonitorOption><b>Source Type</b> &#8211; This determines whether the
camera is a local one attached to a physical video or USB port on your machine,
a remote network camera or an image source that is represented by a file (for
instance periodically downloaded from a alternate location). Choosing one or
the other affects which set of options are shown in the next tab.</p>

</span></span><b>Nodect</b> &#8211; or No DEteCTtion. This is a special mode
designed to be used with external triggers. In Nodect no motion detection takes
place but events are recorded if external triggers require it.</p>
<p class=MonitorOption>Generally speaking it is best to choose
&#8216;Monitor&#8217; as an initial setting here..</p>
<p class=MonitorOption><b>Enabled</b> &#8211; The enabled field indicates whether
the monitor should be started in an active mode or in a more passive state. You
will nearly always want to check this box, the only exceptions being when you
want the camera to be enabled or disabled by external triggers or scripts. If
not enabled then the monitor will not create any events in response ot motion
or any other triggers.</p>
<p class=MonitorOption><b>Maximum FPS</b> &#8211; On some occasions you may
have one or more cameras capable of high capture rates but find that you
generally do not require this performance at all times and would prefer to
lighten the load on your server. This option permits you to limit the maximum
capture rate to a specified value. This may allow you to have more cameras
supported on your system by reducing the CPU load or to allocate video
bandwidth unevenly between cameras sharing the same video device. This value is
only a rough guide and the lower the value you set the less close the actual
FPS may approach it especially on shared devices where it can be difficult to
synchronise two or more different capture rates precisely. There is a global
configuration option that allows you to turn this limiting off in the event of
an alarm.</p>
<p class=MonitorOption><b>Reference Image Blend %ge</b> <b>&#8211; </b>Each
analysed image in ZoneMinder is a composite of previous images and is formed by
applying the current image as a certain percentage of the previous reference
image. Thus, if we entered the value of 10 here, each image&#8217;s part in the
reference image will diminish by a factor of 0.9 each time round. So a typical
reference image will be 10% the previous image, 9% the one before that and then
8.1%, 7.2%, 6.5% and so on of the rest of the way. An image will effectively
vanish around 25 images later than when it was added. This blend value is what
is specified here and if higher will make slower progressing events less
detectable as the reference image would change more quickly. Similarly events
will be deemed to be over much sooner as the reference image adapts to the new
images more quickly. In signal processing terms the higher this value the
steeper the event attack and decay of the signal. It depends on your particular
requirements what the appropriate value would be for you but start with 10 here
and adjust it (usually down) later if necessary.</p>
<p class=MonitorOption><b>Triggers </b>&#8211; This small section lets you
select which triggers will apply if the run mode has been set to
&#8216;triggered&#8217; above. The most common trigger is X10 and this will
appear here if you indicated that your system supported it during installation.
Only X10 is supported as a shipped trigger with ZoneMinder at present but it is
possible that other triggers will become available as necessary. You can also
just use &#8216;cron&#8217; jobs or other mechanisms to actually control the
camera and keep them completely outside of the ZoneMinder settings. The
zmtrigger.pl script is also available to implement custom external triggering.</p>
<p class=MonitorTab>&#8216;Source&#8217; Tab (local device)</p>
<p class=MonitorOption><b>Device Path/Channel</b> &#8211; Enter the full path
to the device file that your camera is attached to, e.g. /dev/video0. Some
video devices, e.g. BTTV cards support multiple cameras on one device so in
this case enter the channel number in the Channel box or leave it at zero if
you're using a USB camera or one with just one channel. </p>
<p class=MonitorOption><b>Device Format</b> &#8211; Enter the video format of
the video stream. This is defined in various system files (e.g.
/usr/include/linux/videodev.h) but the two most common are 0 for PAL and 1 for
NTSC.</p>
<p class=MonitorOption><b>Capture Palette</b> <b>&#8211; </b>Finally for the
video part of the configuration enter the colour depth. ZoneMinder supports a
handful of the most common palettes, so choose one here. If in doubt try grey
first, and then 24 bit colour. If neither of these work very well then YUV420P
or one of the others probably will. There is a slight performance penalty when
using palettes other than grey or 24 bit colour as an internal conversion is
involved. These other formats are intended to be supported natively in a future
version but for now if you have the choice choose one of grey or 24 bit colour.</p>
<p class=MonitorOption><b>Capture Width/Height</b> <b>&#8211; </b>The
dimensions of the video stream your camera will supply. If your camera supports
several just enter the one you'll want to use for this application, you can
always change it later. However I would recommend starting with no larger than
320x240 or 352x288 and then perhaps increasing and seeing how performance is
affected. This size should be adequate in most cases. Some cameras are quite
choosy about the sizes you can use here so unusual sizes such as 197x333 should
be avoided initially.</p>
<p class=MonitorOption><b>Orientation</b> &#8211; If your camera is mounted
upside down or at right angles you can use this field to specify a rotation
that is applied to the image as it is captured. This incurs an additional
processing overhead so if possible it is better to mount your camera the right
way round if you can. If you choose one of the rotation options remember to
switch the height and width fields so that they apply, e.g. if your camera
captures at 352x288 and you choose &#8216;Rotate Right&#8217; here then set the
height to be 352 and width to be 288. You can also choose to &#8216;flip&#8217;
the image if your camera provides mirrored input.</p>
<p class=MonitorTab>&#8216;Source&#8217; Tab (remote device)</p>
<p class=MonitorOption><b>Remote Host/Port/Path</b> &#8211; Use these fields to
enter the full URL of the camera. Basically if your camera is at <span
class=Internetlink>http://camserver.home.net:8192/cameras/camera1.jpg</span>
then these fields will be camserver.home.net, 8192 and /cameras/camera1.jopg
respectively. Leave the port at 80 if there is no special port required. If you
require authentication to access your camera then add this onto the host name
in the form &lt;username&gt;:&lt;password&gt;@&lt;hostname&gt;.com. This will
usually be 24 bit colour even if the image looks black and white.</p>
<p class=MonitorOption><b>Remote Image Colours </b>&#8211; Specify the amount
of colours in the captured image. Unlike with local cameras changing this has
no controlling effect on the remote camera itself so ensure that your camera is
actually capturing to this palette beforehand.</p>
<p class=MonitorOption><b>Capture Width/Height</b> &#8211; As per local
devices.</p>
<p class=MonitorOption><b>Orientation</b> &#8211; As per local devices.</p>
<p class=MonitorTab>&#8216;Source&#8217; Tab (file device)</p>
<p class=MonitorOption><b>File Path</b> &#8211; Enter the full path to the file
to be used as the image source.</p>
<p class=MonitorOption><b>File Colours </b>&#8211; Specify the amount of colours
in the image. Usually 24 bit colour.</p>
<p class=MonitorOption><b>Capture Width/Height</b> &#8211; As per local
devices.</p>
<p class=MonitorOption><b>Orientation</b> &#8211; As per local devices.</p>
<p class=MonitorTab><EFBFBD>&#8216;Timestamp&#8217; Tab</p>
<p class=MonitorOption><b>Timestamp Label Format</b> <b>&#8211; </b>This
relates to the timestamp that is applied to each frame. It is a
&#8216;strftime&#8217; style string. It is actually passed through strftime and
then through printf to add the monitor name so a format of '%%s - %y/%m/%d
%H:%M:%S' (note the double % at the beginning) would be recommended though you
can modify it if necessary. If you don&#8217;t want a timestamp or have a
camera that puts one on itself then leave this field blank. If you add a second
%%s placeholder in the string this will be filled by any of the &#8216;show
text&#8217; detailed in the zmtriggers.pl section.</p>
<p class=MonitorOption><b>Timestamp Label X/Y</b> <b>&#8211; </b>The X and Y
values determine where to put the timestamp. A value of 0 for the X value will
put it on the left side of the image and a Y value of 0 will place it at the
top of the image. To place the timestamp at the bottom of the image use a value
eight less than the image height.</p>
<p class=MonitorTab>&#8216;Buffers&#8217; Tab</p>
<p class=MonitorOption><b>Image Buffer Size</b> <b>&#8211; </b>This option
determines how many frames are held in the ring buffer at any one time. The
ring buffer is the storage space where the last &#8216;n&#8217; images are
kept, ready to be resurrected on an alarm or just kept waiting to be analysed.
It can be any value you like with a couple of provisos, (see next options).
However it is stored in shared memory and making it too large especially for
large images with a high colour depth can use a lot of memory. A value of no
more than 50<35> is usually ok. If you find that your system will not let you use
the value you want it is probably because your system has an arbitrary limit on
the size of shared memory that may be used even though you may have plenty of
free memory available. This limit is usually fairly easy to change, see the
Troubleshooting section for details.</p>
<p class=MonitorOption><b>Warm-up Frames &#8211; </b>This specifies how many
frames the analysis daemon should process but not examine when it starts. This
allows it to generate an accurate reference image from a series of images
before looking too carefully for any changes. I use a value of 25 here, too
high and it will take a long time to start, too low and you will get false
alarms when the analysis daemon starts up.</p>
<p class=MonitorOption><b>Pre/Post Event Image Buffer</b> <b>&#8211; </b>These
options determine how many frames from before and after an event should be
preserved with it. This allows you to view what happened immediately prior and
subsequent to the event. A value of 10 for both of these will get you started
but if you get a lot of short events and would prefer them to run together to
form fewer longer ones then increase the Post Event buffer size. The pre-event
buffer is a true buffer and should not really exceed half the ring buffer size.
However the post-event buffer is just a count that is applied to captured
frames and so can be managed more flexibly. You should also bear in mind the
frame rate of the camera when choosing these values. For instance a network
camera capturing at 1FPS will give you 10 seconds before and after each event
if you chose 10 here. This may well be too much and pad out events more than
necessary. However a fast video card may capture at 25FPS and you will want to
ensure that this setting enables you to view a reasonable time frame pre and
post event.</p>
<p class=MonitorOption><b>Alarm Frame Count</b> &#8211; This option allows you
to specify how many consecutive alarm frames must occur before an alarm event
is generated. The usual, and default, value is 1 which implies that any alarm
frame will cause or participate in an event. You can enter any value up to 16
here to eliminate bogus events caused perhaps by screen flickers or other
transients. Values over 3 or 4 are unlikely to be useful however. Please note
that if you have statistics recording enabled then currently statistics are not
recorded for the first &#8216;Alarm Frame Count&#8217;-1 frames of an event. So
if you set this value to 5 then the first 4 frames will be missing statistics
whereas the more usual value of 1 will ensure that all alarm frames have
statistics recorded.</p>
<p class=MonitorTab>&#8216;Control&#8217; Tab</p>
<p class=MonitorOption><b>Note: This tab and its options will only appear if
you have selected the ZM_OPT_CONTROL option to indicated that your system
contains cameras which are able to be controlled via Pan/Tilt/Zoom or other
mechanisms. See the Camera Control section elsewhere in this document for further
details on camera control protocols and methods.</b></p>
<p class=MonitorOption><b>Controllable &#8211; </b>Check this box to indicate
your camera can be controlled.</p>
<p class=MonitorOption><b>Control Type &#8211; </b>Select the control type that
is appropriate for your camera. ZoneMinder ships with a small number of
predefined control protocols which will works with some cameras without
modification but which may have to amended to function with others, Choose the
edit link to create new control types or to edit the existing ones.</p>
<p class=MonitorOption><b>Control Device &#8211; </b>This is the device that is
used to control your camera. This will normally be a serial or similar port. If
your camera is a network camera, you will generally not need to specify a
control device.</p>
<p class=MonitorOption><b>Control Address &#8211; </b>This is the address of
your camera. Some control protocols require that each camera is identified by a
particular, usually numeric id. If your camera uses addressing then enter the
id of your camera here. If your camera is a network camera then you will
usually need to enter the hostname or IP address of it here. This is ordinarily
the same as that given for the camera itself.</p>
<p class=MonitorOption><b>Auto Stop Timeout &#8211;</b> Some cameras only
support a continuous mode of movement. For instance you tell the camera to pan
right and then when it is aligned correctly you tell it to stop. In some cases
it is difficult to time this precisely over a web interface so this option
allows you to specify an automatic timeout where the command will be
automatically stopped. So a value of 0.25 here can tell the script to stop
moving a quarter of a second after starting. This allows a more precise method
of fine control. If this value is left blank or at zero it will be ignored, if
set then it will be used as the timeout however it will only be applied for the
lower 25% of possible speed ranges. In other words if your camera has a pan
speed range of 1 to 100 then selecting to move at 26 or over will be assumed to
imply that you want a larger movement that you can control yourself and no
timeout will be applied. Selecting motion at lower speeds will be interpreted
as requiring finer control and the automatic timeout will be invoked.</p>
<p class=MonitorOption><b>Track Motion &#8211;</b> This and the following four
options are used with the experimental motion function. This will only work if
your camera supports mapped movement modes where a point on an image can be
mapped to a control command. This is generally most common on network cameras
but can be replicated to some degree on other cameras that support relative
movement modes. See the Camera Control section for more details. Check this box
to enable motion tracking.</p>
<p class=MonitorOption><b>Track Delay &#8211;</b> This is the number of seconds
to suspend motion detection for following any movement that the camera may make
to track motion.</p>
<p class=MonitorOption><b>Return Location &#8211; </b>If you camera supports a
&#8216;home&#8217; position or presets you can choose which preset the camera
should return to after tracking motion.</p>
<p class=MonitorOption><b>Return Delay &#8211; </b>This is the delay, in
seconds, once motion has stopped being detected, before the camera returns to
any defined return location.</p>
<p class=MonitorTab><EFBFBD>&#8216;X10&#8217; Tab</p>
<p class=MonitorOption><b>Note: This tab and its options will only appear if
you have indicated that your system supports the X10 home automation protocol
during initial system configuration.</b></p>
<p class=MonitorOption><b>X10 Activation String</b> - The contents of this
field determine when a monitor starts and/or stops being active when running in
&#8216;Triggered; mode and with X10 triggers. The format of this string is as
follows,</p>
<p class=MsoPlainText style='margin-left:36.0pt'><b>n</b> : If you simply enter
a number then the monitor will be activated when an X10 ON signal for that unit
code is detected and will be deactivated when an OFF signal is detected.</p>
<p class=MsoPlainText style='margin-left:36.0pt'><b>!n</b> : This inverts the previous
mode, e.g. !5 means that the monitor is activated when an OFF signal for unit
code 5 is detected and deactivated by an ON.</p>
<p class=MsoPlainText style='margin-left:36.0pt'><b>n+</b> : Entering a unit
code followed by + means that the monitor is activated on receipt of a ON
signal for that unit code but will ignore the OFF signal and as such will not
be deactivated by this instruction. If you prepend a '!' as per the previous
definition it similarly inverts the mode, i.e. the ON signal deactivates the
monitor.</p>
<p class=MsoPlainText style='margin-left:36.0pt'><b>n+&lt;seconds&gt;</b> : As
per the previous mode except that the monitor will deactivate itself after the
given number of seconds.</p>
<p class=MsoPlainText style='margin-left:36.0pt'><b>n-</b> : Entering a unit
code followed by - means that the monitor is deactivated on receipt of a OFF
signal for that unit code but will ignore the ON signal and as such will not be
activated by this instruction. If you prepend a '!' as per the previous
definition it similarly inverts the mode, i.e. the OFF signal activates the
monitor.</p>
<p class=MsoPlainText style='margin-left:36.0pt'><b>n-&lt;seconds&gt;</b> : As
per the previous mode except that the monitor will activate itself after the
given number of seconds.</p>
<p class=MonitorOption>You can also combine several of these expressions to by
separating them with a comma to create multiple circumstances of activation.
However for now leave this blank.</p>
<p class=MonitorOption><b>X10 Input Alarm String</b> - This has the same format
as the previous field but instead of activating the monitor with will cause a
forced alarm to be generated and an event recorded if the monitor is Active.
The same definition as above applies except that for activated read alarmed and
for deactivated read unalarmed(!). Again leave this blank for now.</p>
<p class=MonitorOption><b>X10 Output Alarm String</b> - This X10 string also
has the same format as the two above options. However it works in a slightly
different way. Instead of ZoneMinder reacting to X10 events this option
controls how ZoneMinder emits X10 signals when the current monitor goes into or
comes out of the alarm state. Thus just entering a number will cause the ON
signal for that unit code to be sent when going into alarm state and the OFF
signal when coming out of alarm state. Similarly 7+30 will send the unit code 7
ON signal when going into alarm state and the OFF signal 30 seconds later
regardless of state. The combination of the X10 instruction allows ZoneMinder
to react intelligently to, and also assume control of, other devices when
necessary. However the indiscriminate use of the Input Alarm and Output Alarm
signals can cause some horrendous race conditions such as a light going on in
response to an alarm which then causes an alarm itself and so on. Thus some
circumspection is required here. Leave this blank for now anyway.</p>
<p class=MonitorTab>&#8216;Misc&#8217; Tab</p>
<p class=MonitorOption><b>Event Prefix</b> &#8211; By default events are named
&#8216;Event-&lt;event id&gt;&#8217;, however you are free to rename them
individually as you wish. This option lets you modify the event prefix, the
&#8216;Event-&#8216; part, to be a value of your choice so that events are
named differently as they are generated. This allows you to name events
according to which monitor generated them. </p>
<p class=MonitorOption><b>Section Length</b> &#8211; This specifies the length
(in seconds) of any fixed length events produced when the monitor function is
&#8216;Record&#8217; or &#8216;Mocord&#8217;. Otherwise it is ignored. This
should not be so long that events are difficult to navigate nor so short that
too many events are generated. A length of between 300 and 900 seconds I
recommended.</p>
<p class=MonitorOption><b>Frame Skip </b>&#8211; This setting also applies only
to the &#8216;Record&#8217; or &#8216;Mocord&#8217; functions and specifies how
many frames should be skipped in the recorded events. The default setting of
zero results in every captured frame being saved. Using a value of one would
mean that one frame is skipped between each saved, two means that two frames
are skipped between each saved frame etc. An alternate way of thinking is that
one in every &#8216;Frame Skip + 1&#8217; frames is saved. The point of this is
to ensure that saved events do not take up too much space unnecessarily whilst
still allowing the camera to capture at a fairly high frame rate. The alternate
approach is to limit the capture frame rate which will obviously affect the
rate at which frames are saved.</p>
<p class=MonitorOption><b>FPS Report Interval</b> <b>&#8211; </b>How often the
current performance in terms of Frames Per Second is output to the system log.
Not used in any functional way so set it to maybe 1000 for now. If you watch
/var/log/messages (normally) you will see this value being emitted at the
frequency you specify both for video capture and processing.</p>
<p class=MonitorOption><b>Default Scale &#8211; </b>If your monitor has been
defined with a particularly large or small image size then you can choose a
default scale here with which to view the monitor so it is easier or more
visible from the web interface.</p>
<p class=MonitorOption><b>Web Colour</b> <b>&#8211; </b>Some elements of
ZoneMinder now use colours to identify monitors on certain views. You can
select which colour is used for each monitor here. Any specification that is
valid for HTML colours is valid here, e.g. &#8216;red&#8217; or
&#8216;#ff0000&#8217;. A small swatch next to the input box displays the colour
you have chosen.</p>
<p class=MsoPlainText>Finally, click 'Save' to add your monitor.</p>
<p class=MsoPlainText>On the main console listing you will now see your monitor
and some of its vital statistics. Most columns are also links and you get to
other functions of ZoneMinder by choosing the appropriate one. Describing them
left to right, they are as follows.</p>
<p class=MsoPlainText>The first column is the Id, clicking on this gives you
the opportunity to edit any of the settings you have just defined your monitor
to have.</p>
<p class=MsoPlainText>The next column is the Name column, clicking on this will
give you the watch window where you can view a live feed from your camera along
with recent events. This is described more fully below.</p>
<p class=MsoPlainText>Following that are the Function and Source columns, which
may be represented in various colours. Initially both will be showing red. This
means that that monitor is not configured for any function and as a consequence
has no zmc (capture) daemon running on it. If it were orange it would mean that
a zmc daemon was running but no zma (analysis) daemon and green means both are
running. In our case it is red because we defined the Monitor to have a
Function of None so no daemons are required.</p>
<p class=MsoPlainText>To get the daemons up and running you can either click on
the source listed in the Source column and edit the monitor properties or click
on the Function listed and change it to &#8217;Monitor&#8217;, which will
ensure that one or more appropriate daemons are started automatically. You need
to ensure that you have started ZoneMinder before any of these settings actually
has any effect.</p>
<p class=MsoPlainText>Having a device status of red or orange does not
necessarily constitute an error if you have deliberately disabled a monitor or
have just put it into Passive mode.</p>
<p class=MsoPlainText>If you have several cameras (and thus monitors) on a
device the device status colour reflects all of them for the capture daemon. So
if just one monitor is active then the daemon is active for both even if all
the other monitors are switched off.</p>
<p class=MsoPlainText>Once you have changed the function of your monitor, the
main console window will be updated to reflect this change. If your device
status does not go green then check your system and web server logs to see if
it's something obvious.</p>
<p class=MsoPlainText>You can now add further monitors if you have cameras set
up to support them. Once you have one or more monitors you may notice the
'&lt;n&gt; Monitors' title becomes a link. Clicking on this link will open up a
window which allows you to assign your monitors to groups. These let you select
certain monitors to view. For instance you may only wish to view outdoor monitors
while indoors. You can also choose to view all of them. If you choose a group
then your selection will be remembered via a cookie and will be used until you
change it. You can call your groups anything you like, though
&#8216;Mobile&#8217; has a special meaning (see Mobile Devices below).</p>
<p class=MsoPlainText>There may also be a &#8216;Cycle&#8217; link which allows
you to cycle through a shot from each of your monitors (in the selected group
unless they are switched off) and get a streamed or still image from each in
turn. Similarly if you see a link titled &#8216;Montage&#8217; it will allow
you view all your active enabled cameras (in the selected group)
simultaneously. Be aware however that this can consume large amounts of
bandwidth and CPU so should not be used continuously unless you have resource
to burn. </p>
<h2><a name="_Toc125113491"><span style='text-decoration:none'>8.2.<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Defining Zones</a></h2>
<p class=MsoPlainText>The next important thing to do with a new monitor is set
up Zones for it to use. By default you'll already have one generated for you
when you created your monitor but you might want to modify it or add others.
Click on the Zones column for your monitor and you should see a small popup
window appear which contains an image from your camera overlain with a stippled
pattern representing your zone. In the default case this will cover the whole
image. The colour of the zones appearing here is determined by what type they
are. The default zone is Active and so will be red, Inclusive zones are orange,
exclusive zones are purple, preclusive zones are blue and inactive zones are
white.</p>
<p class=MsoPlainText>Beneath the zones image will be a table containing a
listing of your zones. Clicking on either the relevant bit of the image or on
the Id or Name in the table will bring up another window where you can edit the
particulars for your Zones. As you can see there are quite a few, so now is a
good time to go through them.</p>
<p class=MsoPlainText>The Zone view is split into two main areas, on the left
is the options are area and on the right is the zone drawing area. A default or
new zone will cover the whole drawing area and will overlay any other zones you
already have on there. Unlike the previous zones image, the current zone is
coloured green, other zones will be orange regardless of type. Your first task
is to decide if you want the zone over the whole image or whether you can
narrow down the detection area; the smaller the zone, the less processing time
it takes to examine it. If you wish to the edit the dimensions of the zone you
can either manually fill in the table containing the zone points under the
image, or click on the zone corners once to select it (it should turn red), and
then click on the desired location to relocate it. Moving your mouse over a
point will highlight the corresponding entry in the points table and vice
versa.</p>
<p class=MsoPlainText>To add a new point, click on the &#8216;+&#8217; next to
the point entry in the point table. This will add another point directly
between that and the next point. To delete a point, select it, and then click
on the &#8216;-&#8216; link. The &#8216;X&#8217; that appears in the same area
just allows you to deselect that point and leave it in the same place. You can
make zones almost any shape you like; except that zones may not self-intersect
(i.e. edges crossing over each other) .</p>
<p class=MsoPlainText>Once you have your zone the correct size and shape, you
should now fill in the rest of the configuration. These options are as follows.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Name</b> &#8211; This is
just a label to identify the zone by. You can change this to be more
representative if you like, though it isn't used much except for logging and
debugging.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Type</b> - This is one of
the more important concepts in ZoneMinder and there are five to choose from.</p>
<p class=MsoPlainText style='margin-left:49.65pt;text-indent:-18.0pt'><span
style='font-family:"Courier New"'>o<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span><b>Active</b> - This is the zone type you'll use most often, and
which will be set for your default zone. This means that this zone will trigger
an alarm on any events that occur within it that meet the selection criteria. </p>
<p class=MsoPlainText style='margin-left:49.65pt;text-indent:-18.0pt'><span
style='font-family:"Courier New"'>o<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span><b>Inclusive</b> - This zone type can be used for any zones that
you want to trigger an alarm only if at least one other Active zone has already
triggered one. This might be for example to cover an area of the image like a
plant or tree which moves a lot and which would trigger lots of alarms. Perhaps
this is behind an area you'd like to monitor though, in this case you'd create
an active zone covering the non-moving parts and an inclusive zone covering the
tree perhaps with less sensitive detection settings also. If something
triggered an alarm in the Active zone and also in the Inclusive zone they would
both be registered and the resulting alarm would be that much bigger than if
you had blanked it out altogether.</p>
<p class=MsoPlainText style='margin-left:49.65pt;text-indent:-18.0pt'><span
style='font-family:"Courier New"'>o<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span><b>Exclusive</b> <20>- The next zone Type is Exclusive. This means
that alarms will only be triggered in this zone if no alarms have already been
triggered in Active zones. This is the most specialised of the zone types and
you may never use it but in its place it is very useful. For instance in the
camera covering my garden I keep watch for a hedgehog that visits most nights and
scoffs the food out of my cats bowls. By creating a sensitive Exclusive zone in
that area I can ensure that a hedgehog alarm will only trigger if there is
activity in that small area. If something much bigger occurs, like someone
walking by it will trigger a regular alarm and not one from the Exclusive zone.
Thus I can ensure I get alarms for big events and also special small events but
not the noise in between.</p>
<p class=MsoPlainText style='margin-left:49.65pt;text-indent:-18.0pt'><span
style='font-family:"Courier New"'>o<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span><b>Preclusive</b> - This zone type is relatively recent. It is
called a Preclusive zone because if it is triggered it actually precludes an
alarm being generated for that image frame. So motion or other changes that
occur in a Preclusive zone will have the effect of ensuring that no alarm
occurs at all. The application for this zone type is primarily as a shortcut
for detecting general large-scale lighting or other changes. Generally this may
be achieved by limiting the maximum number of alarm pixels or other measure in
an Active zone. However in some cases that zone may cover an area where the
area of variable illumination occurs in different places as the sun and/or
shadows move and it thus may be difficult to come up with general values.
Additionally, if the sun comes out rapidly then although the initial change may
be ignored in this way as the reference image catches up an alarm may
ultimately be triggered as the image becomes less different. Using one or more
Preclusive zones offers a different approach. Preclusive zones are designed to
be fairly small, even just a few pixels across, with quite low alarm
thresholds. They should be situated in areas of the image that are less likely
to have motion occur such as high on a wall or in a corner. Should a general
illumination change occur they would be triggered at least as early as any
Active zones and prevent any other zones from generating an alarm. Obviously
careful placement is required to ensure that they do not cancel any genuine
alarms or that they are not so close together that any motion just hops from
one Preclusive zone to another. As always, the best way is to experiment a
little and see what works for you.</p>
<p class=MsoPlainText style='margin-left:49.65pt;text-indent:-18.0pt'><span
style='font-family:"Courier New"'>o<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span><b>Inactive</b> - This final zone type is the opposite of Active.
In this zone type no alarms will ever be reported. You can create an Inactive
zone to cover any areas in which nothing notable will ever happen or where you
get constant false alarms that don't relate to what you are trying to monitor.
An Inactive zone can overlay other zone types and will be processed first.</p>
<p class=MsoPlainText style='margin-left:27.0pt'>It was mentioned above that
Inactive zones may be overlaid on other zones to blank out areas however as a
general principle you should try and make zones abut each other as much as
possible and not overlap. This helps avoid repeated duplicate processing of the
same area. For instance an Inclusive zone overlaying an Active zone when all
other settings are the same will always trigger when the Active zone does which
somewhat defeats the object of the exercise. One exception to this is
Preclusive zones. These may be situated within Active areas are they are
processed first and if small may actually save processing time by preventing
full analysis of the image.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Presets</b> &#8211; This
contains a predefined list of some common zone settings. Selecting one will
fill in some of the other fields in the page and help you to pick appropriate
values for your zones. Note that it may be that none of the presets will be
appropriate for your purposes so it is worth going through the individual
options below to ensure that each has a sensible value. </p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Units</b> - This setting
which details whether certain of the following settings are in Pixels or
Percent, where &#8216;Percent&#8217; refers to a percentage area of the zone
itself. In general &#8216;Pixels&#8217; is more precise whereas percentages are
easier to use to start with or if you change image sizes frequently. If you
change this setting all appropriate values below are redisplayed in the correct
context. A good tip would be to initially enter the settings in Percent and
then change to Pixels if you wish to be more precise. Be aware though that
repeated flipping between the settings may cause rounding errors. Note, the
sense of the percentage values refers to the area of the zone and not the image
as a whole. This makes trying to work out necessary sizes rather easier.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Alarm Colour </b>- The
option after that allows you to specify what colour you'd like any alarms this
zone generates to be highlighted on images. Pick anything you like that will
show up against your normal image background. This option is irrelevant for
Preclusive and Inactive zones and will be disabled. For Inactive zones all
subsequent options are likewise disabled.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Alarm Check Method </b>&#8211;This
setting allows you to specify the nature of the alarm checking that will take
place, and more specifically what tests are applied to determine whether a
frame represents an alarm or not. The three options are
&#8216;AlarmPixels&#8217;, &#8216;FilteredPixels&#8217; and &#8216;Blobs&#8217;
and depending on which option is chosen some of the following other settings
may become unavailable. The first of these indicates that only a count of individual
alarmed pixels should be used to determine the state of a image, the second
indicate that the pixels should be filtered to remove isolated pixels (see
below) before being counted, and the third uses a more sophisticated analysis
which is designed to aggregate alarmed pixels into continuous groups, or
&#8216;blobs&#8217;. Blob analysis default, however this method takes slightly
longer and so if you find that one of the other methods works just as well for
you and you wish to maximise performance you can opt for that instead. Some of
the more useful alarm related features such as highlighted analysis images are
only available with the &#8216;Blob&#8217; setting.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Min/Maximum Pixel Threshold</b>
&#8211; These setting are used to define limits for the difference in value
between a pixel and its predecessor in the reference image. For greyscale
images this is simple but for colour images the colours are averaged first,
originally this used an RMS (root mean squared) algorithm but calculating
square roots mugs performance and does not seem to improve detection. Using an
average means that subtle colour changes without any brightness change may go
undetected but this is not the normal circumstance. There is also the option to
use a more sophisticated integer algorithm to calculate a Y (or brightness)
value from the colours themselves.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Filter Width/Height</b>
&#8211; To improve detection of valid event ZoneMinder applies several other
functions to the data to improve its ability to distinguish interesting signals
from uninteresting noise. The first of these is a filter that removes any pixels
that do not participate in a contiguous block of pixels above a certain size.
These options are always expressed in pixels and should be fairly small, and an
odd number, three or five is a good value to choose initially. Application of
this filter removes any tiny or discontinuous pixels that don't form part of a
discrete block. </p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Zone Area</b> &#8211; This
field differs from the others in that it may not be written to. It is there
purely as a useful reference, when working in pixel units, of the area of the
zone.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Min/Maximum Alarmed Area</b>
- The following two settings define the minimum and maximum number of pixels
that exceed this threshold that would cause an alarm. If the units are Percent
this (and following options) refers to the percentage of the frame and not the
zone, this is so these values can be related between zones. The minimum value
must be matched or exceeded for an alarm to be generated whereas the maximum
must not be exceeded or the alarm will be cancelled. This is to allow for
sudden changes such as lights coming on etc, which you may wish to disregard.
In general a value of zero for any of these settings causes that value to be
ignored, so you can safely set a maximum to zero and it will not be used. The
use of just a number of pixels is however a very brute force method of
detection as many small events dispersed widely are not distinguished from a
compact one.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Min/Maximum Filtered Area</b>
&#8211; These are two additional bounds that specify the limits of pixels that
would cause an alarm after this filtering process. As the filtering process can
only remove alarmed pixels it makes no sense for the Minimum and Maximum
Filtered Area to be larger than the equivalent Alarmed Area and in general they
should be smaller or the same.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Min/Maximum Blob Area</b> -
The next step in the analysis phase is the collation of any remaining alarmed
areas into contiguous blobs. This process parses the image and forms any pixels
that adjoin other alarmed pixels into one or more larger blobs. These blobs may
be any shape and can be as large as the zone itself or as small as the filtered
size. The Minimum and Maximum Blob Size settings allow you to define limits
within which an alarm will be generated. Of these only the Minimum is likely to
be very useful.</p>
<p class=MsoPlainText style='margin-left:27.0pt'><b>Min/Maximum Blobs </b>-
Finally the Minimum and Maximum Blobs settings specify the limits of the actual
number of blobs detected. If an image change satisfies all these requirements
it starts or continues an alarm event.</p>

</span></span>Viewing Monitors</a></h2>
<p class=MsoPlainText>As this point you should have one or more Monitors running
with one or more Zones each. Returning to the main Console window you will see
your monitors listed once more. The columns not explored so far are the Monitor
name, and various event totals for certain periods of time. Clicking on any of
the event totals will bring up a variation on the same window but click on the
Monitor name for now. If it is not a link then this means that that monitor is
not running so ensure that you have started ZoneMinder and that your Monitor
function is not set to &#8216;None&#8217;. If the link works, clicking on it
will pop another window up which should be scaled to contain a heading, an
image from your monitor, a status and a list of recent events if any have been
generated.</p>
<p class=MsoPlainText>Depending on whether you are able to view a streamed
image or not the image frame will either be this stream or a series of stills.
You have the option to change from one to the other (if available) at the
centre of the top heading. Also along the top are a handful of other links.
These let you change the scale of the image stream, modify image settings (for
local devices) or close the window. If you have cameras that can be controlled,
a &#8216;Control&#8217; link should also be present which is described below.</p>
<p class=MsoPlainText>The image should be self-explanatory but if it looks like
garbage it is possible that the video configuration is wrong so look in your
system error log and check for or report anything unusual. The centre of the
window will have a tiny frame that just contains a status; this will be 'Idle',
'Alarm' or 'Alert' depending on the function of the Monitor and what's going on
in the field of view. Idle means nothing is happening, Alarm means there is an
alarm in progress and Alert means that an alarm has happened and the monitor is
&#8216;cooling down&#8217;, if another alarm is generated in this time it will
just become part of the same event. These indicators are colour coded in green,
red and amber.</p>
<p class=MsoPlainText>By default if you have minimised this window or opened
other windows in front it will pop up to the front if it goes to Alarm state.
This behaviour can be turned off in &#8216;options&#8217; if required. You can
also specify a sound file in the configuration, which will be played when an
alarm occurs to alert you to the fact if you are not in front of your computer.
This should be a short sound of only a couple of seconds ideally. Note that as
the status is refreshed every few seconds it is possible for this not to alert
you to every event that takes place, so you shouldn't rely on it for this
purpose if you expect very brief events. Alternatively you can decrease the
refresh interval for this window in the configuration though having too
frequent refreshing may impact on performance.</p>
<p class=MsoPlainText>Below the status is a list of recent events that have
occurred, by default this<69> is a listing of just the last 10 but clicking on
'All' will give you a full list<73> and 'Archive' will take you to the event
archive for this monitor, more on this<69> later. Clicking on any of the column
headings will sort the events appropriately.</p>
<p class=MsoPlainText>From here you can also delete events if you wish. The
events themselves are listed with the event id, and event name (which you can
change), the time that the event occurred, the length of the event including
any preamble and postamble frames, the number of frames comprising the event
with the number that actually contain an alarm in brackets and finally a score.
This column lists the average score per alarm frame as well as the maximum
score that any alarm frame had.</p>
<p class=MsoPlainText>The score is an arbitrary value that essentially
represents the percentage of pixels in the zone that are in blobs divided by
the square root of the number of blobs and then divided by the size of the
zone. This gives a nominal maximum of 100 for a zone and the totals for each
zone are added together, Active zones scores are added unchanged, Inclusive
zones are halved first and Exclusive zones are doubled. In reality values are
likely to be much less than 100 but it does give a simple indication of how
major the event was.</p>
<h2><a name="_Toc125113493"><span style='text-decoration:none'>8.4.<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Controlling Monitors</a></h2>
<p class=MsoPlainText>If you have defined your system as having controllable
monitors and you are looking at a monitor that is configured for control, then
clicking on the &#8216;Control&#8217; link along the top of the window will
change the short event listing area to a control area. The capabilities you
have defined earlier determine exactly what is displayed in this window.
Generally you will have a Pan/Tilt control area along with one or subsidiary
areas such as zoom or focus control to the side. If you have preset support
then these will be near the bottom of the window. The normal method of
controlling the monitor is by clicking on the appropriate graphics which then
send a command via the control script to the camera itself. This may sometimes
take a noticeable delay before the camera responds.</p>
<p class=MsoPlainText>It is usually the case that the control arrows are
sensitive to where you click on them. If you have a camera that allows
different speeds to be used for panning or zooming etc then clicking near the
point of the arrow will invoke the faster speed whilst clicking near the base
of the arrow will be slower. If you have defined continuous motion then ongoing
activities can be stopped by clicking on the area between the arrows, which
will either be a graphic in the case of pan/tilt controls or a word in the case
of zoom and focus controls etc.</p>
<p class=MsoPlainText>Certain control capabilities such as mapped motion allow
direct control by clicking on the image itself when used in browsers which
support streamed images directly. Used in this way you can just click on the
area of the image that interests you and the camera will centre on that spot.
You can also use direct image control for relative motion when the area of the
image you click on defines the direction and the distance away from the centre
of the image determines the speed. As it is not always very easy to estimate
direction near the centre of the image, the active area does not start until a
short distance away from the centre, resulting in a &#8216;dead&#8217; zone in
the middle of the image.</p>
<h2><a name="_Toc125113494"><span style='text-decoration:none'>8.5.<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Filtering Events</a></h2>
<p class=MsoPlainText>The other columns on the main console window contain
various event totals for your monitors over the last hour, day, week and month
as well as a grand total and a total for events that you may have archived for
safekeeping. Clicking on one of these totals or on the 'All' or 'Archive' links
from the monitor window described above will present you with a new display.
This is the full event window and contains a list of events selected according
to a filter which will also pop up in its own window. Thus if you clicked on a
'day' total the filter will indicate that this is the period for which events
are being filtered. The event listing window contains a similar listing to the
recent events in the monitor window. The primary differences are that the
frames and alarm frames and the score and maximum score are now broken out into
their own columns, all of which can be sorted by clicking on the heading. Also
this window will not refresh automatically, rather only on request. Other than
that, you can choose to view events here or delete them as before.</p>
<p class=MsoPlainText>The other window that appeared is a filter window. You
can use this window to create your own filters or to modify existing ones. You
can even save your favourite filters to re-use at a future date. Filtering
itself is fairly simple; you first choose how many expressions you'd like your
filter to contain. Changing this value will cause the window to redraw with a
corresponding row for each expression. You then select what you want to filter
on and how the expressions relate by choosing whether they are 'and' or 'or'
relationships. For filters comprised of many expressions you will also get the
option to bracket parts of the filter to ensure you can express it as desired.
Then if you like choose how you want your results sorted and whether you want
to limit the amount of events displayed.</p>
<p class=MsoPlainText>There are several different elements to an event that you
can filter on, some of which require further explanation. These are as follows,
'Date/Time' which must evaluate to a date and a time together, 'Date' and
'Time' which are variants which may only contain the relevant subsets of this,
'Weekday' which as expected is a day of the week.</p>
<p class=MsoPlainText>All of the preceding elements take a very flexible free
format of dates and time based on the PHP strtotime function
(http://www.php.net/manual/en/function.strtotime.php). This allows values such
as 'last Wednesday' etc to be entered. I recommend acquainting yourself with
this function to see what the allowed formats are. However automated filters
are run in perl and so are parsed by the Date::Manip package. Not all date
formats are available in both so if you are saved your filter to do automatic
deletions or other tasks you should make sure that the date and time format you
use is compatible with both methods. The safest type of format to use is
&#8216;-3 day&#8217; or similar with easily parseable numbers and units are in
English.</p>
<p class=MsoPlainText>The other things you can filter on are all fairly self
explanatory, except perhaps for 'Archived' which you can use to include or
exclude Archived events. In general you'll probably do most filtering on un-archived
events. There are also two elements, Disk Blocks and Disk Percent which
don&#8217;t directly relate to the events themselves but to the disk partition
on which the events are stored. These allow you to specify an amount of disk
usage either in blocks or in percentage as returned by the &#8216;df&#8217;
command. They relate to the amount of disk space used and not the amount left
free. Once your filter is specified, clicking 'submit' will filter the events
according to your specification. As the disk based elements are not event
related directly if you create a filter and include the term &#8216;DiskPercent
&gt; 95&#8217; then if your current disk usage is over that amount when you
submit the filter then all events will be listed whereas if it is less then
none at all will. As such the disk related terms will tend to be used mostly
for automatic filters (see below). If you have created a filter you want to
keep, you can name it and save it by clicking 'Save'.</p>
<p class=MsoPlainText>If you do this then the subsequent dialog will also allow
you specify whether you want this filter automatically applied in order to
delete events or upload events via ftp to another server and mail notifications
of events to one or more email accounts. Emails and messages (essentially small
emails intended for mobile phones or pagers) have a format defined in the
Options screen, and may include a variety of tokens that can be substituted for
various details of the event that caused them. This includes links to the event
view or the filter as well as the option of attaching images or videos to the
email itself. Be aware that tokens that represent links may require you to log
in to access the actual page, and sometimes may function differently when
viewed outside of the general ZoneMinder context. The tokens you can use are as
follows.</p>

<p class=MsoPlainText>Finally you can also specify a script which is run on
each matched event. This script should be readable and executable by your web
server user. It will get run once per event and the relative path to the
directory containing the event in question. Normally this will be of the form
&lt;MonitorName&gt;/&lt;EventId&gt; so from this path you can derive both the
monitor name and event id and perform any action you wish. Note that arbitrary
commands are not allowed to be specified in the filter, for security the only thing
it may contain is the full path to an executable. What that contains is
entirely up to you however.</p>
<p class=MsoPlainText>Filtering is a powerful mechanism you can use to
eliminate events that fit a certain pattern however in many cases modifying the
zone settings will better address this. Where it really comes into its own is
generally in applying time filters, so for instance events that happen during
weekdays or at certain times of the day are highlighted, uploaded or deleted.
Additionally using disk related terms in your filters means you can
automatically create filters that delete the oldest events when your disk gets
full. Be warned however that if you use this strategy then you should limit the
returned results to the amount of events you want deleted in each pass until
the disk usage is at an acceptable level. If you do not do this then the first
pass when the disk usage is high will match, and then delete, all events unless
you have used other criteria inside of limits. ZoneMinder ships with a sample
filter already installed, though disabled. The PurgeWhenFull filter can be used
to delete the oldest events when your disk starts filling up. To use it you
should select and load it in the filter interface, modify it to your
requirements, and then save it making you sure you check the &#8216;Delete
Matching Events&#8217; option. This will then run in the background and ensure
that your disk does not fill up with events.</p>

</span></span>Viewing Events</a></h2>
<p class=MsoPlainText>From the monitor or filtered events listing you can now
click on an event to view it in more detail. If you have streaming capability
you will see a series of images that make up the event. Under that you should
also see a progress bar. Depending on your configuration this will either be
static or will be filled in to indicate how far through the event you are. By
default this functionality is turned off for low bandwidth settings as the
image delivery tends to not be able to keep up with real-time and the progress
bar cannot take this into account. Regardless of whether the progress bar
updates, you can click on it to navigate to particular points in the events.</p>
<p class=MsoPlainText>You will also see a link to allow you to view the still
images themselves. If you don't have streaming then you will be taken directly
to this page. The images themselves are thumbnail size and depending on the
configuration and bandwidth you have chosen will either be the full images
scaled in your browser of actual scaled images. If it is the latter, if you
have low bandwidth for example, it may take a few seconds to generate the
images. If thumbnail images are required to be generated, they will be kept and
not re-generated in future. Once the images appear you can mouse over them to
get the image sequence number and the image score.</p>
<p class=MsoPlainText>You will notice for the first time that alarm images now
contain an overlay outlining the blobs that represent the alarmed area. This
outline is in the colour defined for that zone and lets you see what it was
that caused the alarm. Clicking on one of the thumbnails will take you to a
full size window where you can see the image in all its detail and scroll
through the various images that make up the event. If you have the
ZM_RECORD_EVENT_STATS option on, you will be able to click the 'Stats' link
here and get some analysis of the cause of the event. Should you determine that
you don't wish to keep the event, clicking on Delete will erase it from the
database and file system. Returning to the event window, other options here are
renaming the event to something more meaningful, refreshing the window to
replay the event stream, deleting the event, switching between streamed and
still versions of the event (if supported) and generating an MPEG video of the
event (if supported).</p>
<p class=MsoPlainText>These last two options require further explanation.
Archiving an event means that it is kept to one side and not displayed in the
normal event listings unless you specifically ask to view the archived events.
This is useful for keeping events that you think may be important or just wish
to protect. Once an event is archived it can be deleted or unarchived but you
cannot accidentally delete it when viewing normal unarchived events.</p>
<p class=MsoPlainText>The final option of generating an MPEG video is still
somewhat experimental and its usefulness may vary. It uses the open source
ffmpeg encoder to generate short videos, which will be downloaded to your
browsing machine or viewed in place. When using the ffmpeg encoder, ZoneMinder
will attempt to match the duration of the video with the duration of the event.
Ffmpeg has a particularly rich set of options and you can specify during
configuration which additional options you may wish to include to suit your
preferences. In particular you may need to specify additional, or different,
options if you are creating videos of events with particularly slow frame rates
as some codecs only support certain ranges of frame rates. Details of these
options can be found in the documentation for the encoders and is outside the
scope of this document.</p>
<p class=MsoPlainText>Building an MPEG video, especially for a large event, can
take some time and should not be undertaken lightly as the effect on your host
box of many CPU intensive encoders will not be good. However once a video has
been created for an event it will be kept so subsequent viewing will not incur
the generation overhead. Videos can also be included in notification emails,
however care should be taken when using this option as for many frequent events
the penalty in CPU and disk space can quickly mount up.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Options and Users</a></h2>
<p class=MsoPlainText>The final area covered by the tutorial is the options and
user section. If you are running in authenticated mode and don&#8217;t have
system privileges then you will not see this section at all and if you are
running in un-authenticated mode then no user section will be displayed.</p>
<p class=MsoPlainText>The various options you can specify are displayed in a
tabbed dialog with each group of options displayed under a different heading.
Each option is displayed with its name, a short description and the current
value. You can also click on the &#8216;?&#8217; link following each
description to get a fuller explanation about each option. This is the same as
you would get from zmconfig.pl. A number of option groups have a master option
near the top which enables or disables the whole group so you should be aware
of the state of this before modifying options and expecting them to make any
difference.</p>
<p class=MsoPlainText>If you have changed the value of an option you should
then &#8216;save&#8217; it. A number of the option groups will then prompt you
to let you know that the option(s) you have changed will require a system
restart. This is not done automatically in case you will be changing many
values in the same session, however once you have made all of your changes you
should restart ZoneMinder as soon as possible. The reason for this is that web
and some scripts will pick up the new changes immediately but some of the
daemons will still be using the old values and this can lead to data
inconsistency or loss.</p>
<p class=MsoPlainText>One of the options you may notice in the
&#8216;System&#8217; tab allows you to specify the default language for your
installation of ZoneMinder. Versions 1.17.0 and later support multiple
languages but rely on users to assist in creating language files for specific
languages. To specify a language you will have to give the applicable code,
thus for UK English this is en_gb, and for US English it would be en_us, if no
language is given then UK English is assumed. Most languages will be specified
in this nn_mm format and to check which languages are available look for files
named zm_lang_*.php in the ZoneMinder build directory where the parts
represented by the &#8216;*&#8217; would be what you would enter as a language.
This is slightly unwieldy and will probably be improved in future to make it
easier to determine language availability. On checking which languages are
available it may be that your preferred language is not currently included and
if this is the case please consider doing a translation and sending it back to
it may be included in future releases. All the language elements are given in
the zm_lang_en_gb.php file along with a few notes to help you understand the
format.</p>
<p class=MsoPlainText>As mentioned above, you may also see a
&#8216;users&#8217; tab in the Options area. In this section you will see a
list of the current users defined on the system. You can also add or delete
users from here. It is recommended you do not delete the admin user unless you
have created another fully privileged user to take over the same role. Each
user is defined with a name and password (which is hidden) as well as an
enabled setting which you can use to temporarily enable or disable users, for
example a guest user for limited time access. As well as that there is a
language setting that allows you to define user specific languages. Setting a
language here that is different than the system language will mean that when
that user logs in they will have the web interface presented in their own
language rather than the system default, if it is available. Specifying a
language here is done in the same way as for the system default language
described above.</p>
<p class=MsoPlainText>There are also five values that define the user
permissions, these are &#8216;Stream&#8217;, &#8216;Events&#8217;,
&#8216;Control&#8217;, &#8216;Monitors&#8217; and &#8216;System&#8217; Each can
have values of &#8216;None&#8217;, &#8216;View&#8217; or &#8216;Edit&#8217;
apart from &#8216;Stream&#8217; which has no &#8216;Edit&#8217; setting. These
values cover access to the following areas; &#8216;Stream&#8217; defines
whether a user is allowed to view the &#8216;live&#8217; video feeds coming
from the cameras. You may wish to allow a user to view historical events only
in which case this setting should be &#8216;none&#8217;. The
&#8216;Events&#8217; setting determines whether a user can view and modify or
delete any retained historical events. The &#8216;Control&#8217; setting allows
you to indicate whether the user is able to control any Pan/Tilt/Zoom type
cameras you may have on your system. The &#8216;Monitors&#8217; setting
specifies whether a user can see the current monitor settings and change them.
Finally the &#8216;System&#8217; setting determines whether a user can view or
modify the system settings as a whole, such as options and users or controlling
the running of the system as a whole.</p>
<p class=MsoPlainText>As well as these settings there is also a
&#8216;Bandwidth&#8217; setting which can be used to limit the maximum
bandwidth that a user can view at and a &#8216;Monitor Ids&#8217; setting that
can be used for non-&#8217;System&#8217; users to restrict them to only being
able to access streams, events or monitors for the given monitors ids as a
comma separated list with no spaces. If a user with &#8216;Monitors&#8217; edit
privileges is limited to specific monitors here they will not be able to add or
delete monitors but only change the details of those they have access to. If a
user has &#8216;System&#8217; privileges then the &#8216;Monitors Ids&#8217;
setting is ignored and has no effect.&#8217;</p>
<p class=MsoPlainText>That&#8217;s pretty much is it for the tour, though there
is a lot more to ZoneMinder as you will discover. You should experiment with
the various setting to get the results you think are right for your
requirements.</p>

<h1><a name="_Toc125113497"><span style='text-decoration:none'>9.<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span></span><u>Camera
Control</u></a></h1>
<p class=MsoPlainText>Version 1.21.0 of ZoneMinder introduced a new feature,
allowing you to control cameras from the web interface and to some extent
automatically. Pan/Tilt/Zoom (PTZ) cameras have a wide range of capabilities
and use a large number of different protocols making any kind of generic
control solution potentially very difficult. To address this ZoneMinder uses
two key approaches to get around this problem.</p>
<p class=MsoPlainText><b>1) Definition of Capabilities</b> &#8211; For each
camera model you use, an entry in the camera capabilities table must be
created. These indicate what functions the camera supports and ensure that the
interface presents only those capabilities that the camera supports. There are
a very large number of capabilities that may be supported and it is very
important that the entries in this table reflect the actual abilities of the
camera. A small number of example capabilities are included in ZoneMinder,
these can be used &#8216;as is&#8217; or modified.</p>
<p class=MsoPlainText><b>2) Control Scripts &#8211;</b> ZoneMinder itself does
not generally provide the ability to send commands to cameras or receive
responses. What it does is mediate motion requests from the web interface into
a standard set of commands which are passed to a script defined in the control
capability. Example scripts are provided in ZoneMinder which support a number
of serial or network protocols but it is likely that for many cameras new
scripts will have to be created. These can be modelled on the example ones, or
if control commands already exist from other applications, then the script can
just act as a &#8216;glue&#8217; layer between ZoneMinder and those commands.</p>
<p class=MsoPlainText>It should be emphasised that the control and capability
elements of ZoneMinder are not intended to be able to support every camera out
of the box. Some degree of development is likely to be required for many
cameras. This should often be a relatively straightforward task however if you
have a camera that you want to be supported then please feel free to get in
touch and I should be able to provide an estimate for how much effort this is
likely to be. It is also the case that I have only been able to access this
limited number of cameras to test against; some other cameras may use different
motion paradigms that don&#8217;t fit into the control capability/script
architecture that ZoneMinder uses. If you come across any cameras like this
then please forward as much information to me as possible so that I may be able
to extend the ZoneMinder model to encompass them.</p>

</span></span>Control Capabilities</a></h2>
<p class=MsoPlainText>If you have a camera that supports PTZ controls and wish
to use it with ZoneMinder then the first thing you need to do is ensure that it
has an accurate entry in the capabilities table. To do this you need to go to
the Control tab of the Monitor configuration dialog and select
&#8216;Edit&#8217; where it is listed by the Control Type selection box. This
will bring up a new window which lists, with a brief summary, the existing
capabilities. To edit an existing capability to modify select the Id or Name of
the capability in question, or click on the Add button to add a new control
capability. Either of these approaches will create a new window, in familiar
style, with tabs along the top and forms fields below. In the case of the
capabilities table there are a large number of settings and tabs, the mean and
use of these are briefly explained below.</p>
<p class=MonitorTab>&#8216;Main&#8217; Tab</p>
<p class=MsoPlainText style='margin-top:0cm;margin-right:0cm;margin-bottom:

</span></span>Control Scripts</a></h2>
<p class=MsoPlainText>The second key element to controlling cameras with
ZoneMinder is ensuring that an appropriate control script or application is
present. A small number of sample scripts are included with ZoneMinder and can
be used directly or as the basis for development. Control scripts are run
atomically, that is to say that one requested action from the web interface
results in one execution of the script and no state information is maintained.
If your protocol requires state information to be preserved then you should
ensure that your scripts do this as ZoneMinder has no concept of the state of
the camera in control terms.</p>
<p class=MsoPlainText>If you are writing a new control script then you need to
ensure that it supports the parameters that ZoneMinder will pass to it. If you
already have scripts or applications that control your cameras, the ZoneMinder
control script will just act as glue to convert the parameters passed into a
form that your existing application understands. If you are writing a script to
support a new protocol then you will need to convert the parameters passed into
the script to equivalent protocol commands. If you have carefully defined your
control capabilities above then you should only expect commands that correspond
to those capabilities.</p>
<p class=MsoPlainText>The standard set of parameters passed to control scripts
is defined below,</p>

<p class=MsoPlainText>ZoneMinder has always had a minimal WML (Wireless Markup
Language) capability to allow it to function on mobile phones and similar
devices. However as of 1.20.0 this is now deprecated and has been replaced with
a new XHTML &#8211; Mobile Profile mode as well as the default HTML4. XHTML-MP
is a small, and limited, version of XHTML intended for mobile devices and is
based on XHTML Basic. It does not contain scripting or other dynamic elements
and essentially is a subset of HTML as most people know it.</p>
<p class=MsoPlainText>The ZoneMinder XHTML-MP interface allows you to log into
your installation via your phone or mobile devices and perform a limited number
of tasks. These include viewing recent events, and monitoring live streams.
However unlike the full interfaces these elements are presented as still images
requiring manual refreshing. For now the XHTML-MP interface is presented as a
prototype interface; rather than one offering full capabilities. As such,
please feel free to make comments or offer suggestions via the forums on <span
class=Internetlink><a href="http://www.zoneminder.com/">http://www.zoneminder.com</a></span>.</p>
<p class=MsoPlainText>As well as XHTML-MP, ideally I&#8217;d like to be able to
offer a WML2.0 interface. WML2.0 is a blending of WML1.3, which is traditional
WAP, and XHTML. As such it offers the scripting that WML has traditionally
included plus the better control of mark-up that is the realm of XHTML.
Unfortunately so far I&#8217;m unaware of any devices that support WML2.0 even
if they say they are WAP2 compliant, certainly I&#8217;ve never had a phone
that does. If you find out that a particular phone does support this then
please let me know (or better still send me the phone!).</p>
<p class=MsoPlainText>If you wish to use the XHTML-MP interface to ZoneMinder
there is no extra configuration required to enable it per se. However
ZoneMinder needs to be able to figure out what kind of content to deliver to
particular browsers, so you have two choices. You can edit zm.php and include a
definition that corresponds to your phone, describing a small number of basic
capabilities, you will see a couple of examples already there, or you can use
the comprehensive open source WURFL package available from <span
class=Internetlink><a href="http://wurfl.sourceforge.net/">http://wurfl.sourceforge.net/</a></span>.
You will need to download both the WURFL php files and the wurfl.xml file
itself. WURFL is a resource containing information on the capabilities of a
huge number of mobile phones, devices and browsers. Thus once it has matched
your phone it can determine various capabilities it may possess. This means
that ZoneMinder itself only has to deal with these capabilities and not the
individual phone types.</p>
<p class=MsoPlainText>To use WURFL you should install the php files in the same
directory as ZoneMinder and then create a &#8216;wurfl&#8217; sub-directory and
ensure it is readable and writeable (or preferably owned by) your web server
user. You should put the wurfl.xml file in there. One other thing you may need
to change, as the xml file is quite large, is the &#8216;memory_limit&#8217;
setting in php.ini as the default setting of 8Mb may be too small. Once
you&#8217;ve done this you should find that your phone or device is recognised
and if it can support XHTML-MP it will receive that interface. If your phone is
very new, or you are using an old version of the XML file you might find that
it is not present however. The WURFL library uses a caching strategy to avoid
reloading the whole XML file each time so check if a sensible looking cache
file has been created in the &#8216;wurfl&#8217; sub-directory also check the
wurfl.log in the same place.</p>
<p class=MsoPlainText>The WURFL is a third party application and as such I am
unable to offer support directly for it. If you feel your device is missing or
incorrectly represented please contact the authors via their own channels. If
on the other hand you have any comments on ZoneMinder on your device
specifically please let me know and I would be pleased to hear about it.</p>
<p class=MsoPlainText>As support for cookies in mobile devices is patchy at
best, the groups feature is not fully implemented in the XHTML-MP views.
Instead if there is a group called &#8216;Mobile&#8217; already defined then
that group will always be effective, if not then all monitors available to the
logged in user will be visible,</p>

first and see if anyone has had the same problem in the past. If not then feel
free to get in touch and I'll see if I can suggest something else. Please
ensure that you read the posting guidelines and go through the steps listed
below before posting or mailing though.</p>
<p class=MsoPlainText>The first thing you need to do is check the ZoneMinder
logs to see if you can find out what is and what isn&#8217;t working. Most
components of ZoneMinder can emit informational, warning, error and debug
messages in a standard format. These messages can be logged in one or more
locations. By default all messages produced by scripts are logged in &lt;script
name&gt;.log files which are placed in the directory defined by the
ZM_PATH_LOGS configuration variable. This is initially defined as
&#8216;/tmp&#8217; though it can be overridden (see the Options and Users
section above). So for example, the zmpkg.pl script will output messages to
/tmp/zmpkg.pl, an example of these messages is</p>
<p class=MsoPlainText>03/01/06 13:46:00.166046 zmpkg[11148].INF [Command:
start]</p>
<p class=MsoPlainText>where the first part refers to the date and time of the
entry, the next section is the name (or an abbreviated version) of the script,
followed by the process id in square brackets, a severity code (INF, WAR, ERR
or DBG) and the debug text. If you change the location of the log directory,
ensure it refers to an existing directory which the web user has permissions to
write to. Also ensure that no logs are present in that directory the web user
does not have permission to open. This can happen if you run commands or
scripts as the root user for testing at some point. If this occurs then
subsequent non-privileged runs will fails due to being unable to open the log
files.</p>
<p class=MsoPlainText>As well as specific script logging above, information,
warning and error messages are logged via the system syslog service. This is a
standard component on Linux systems and allows logging of all sorts of messages
in a standard way and using a standard format. On most systems, unless
otherwise configured, messages produced by ZoneMinder will go to the
/var/log/messages file. On some distributions they may end up in another file,
but usually still in /var/log. Messages in this file are similar to those in
the script log files but differ slightly. For example the above event in the
system log file looks like</p>
<p class=MsoPlainText>Jan<EFBFBD> 3 13:46:00 shuttle52 zmpkg[11148]: INF [Command:
start]</p>
<p class=MsoPlainText>where you can see that the date is formatted differently
(and only to 1 second precision) and there is an additional field for the
hostname (as syslog can operate over a network). As well as ZoneMinder entries
in this file you may also see entries from various other system components.</p>
<p class=MsoPlainText>A number of users have asked how to suppress or redirect
ZoneMinder messages that are written to this file. This most often occurs due
to not wanting other system messages to be overwhelmed and obscured by the
ZoneMinder produced ones (which can be quite frequent by default). In order to
control syslog messages you need to locate and edit the syslog.conf file on
your system. This will often be in the /etc directory. This file allows
configuration of syslog so that certain classes and categories of messages are
routed to different files or highlighted to a console, or just ignored. Full
details of the format of this file is outside the scope of this document
(typing &#8216;man syslog.conf&#8217; will give you more information) but the
most often requested changes are easy to implement.</p>
<p class=MsoPlainText>The syslog service uses the concept of priorities and
facilities where the former refers to the importance of the message and the
latter refers to that part of the system from which it originated. Standard
priorities include &#8216;info&#8217;, &#8216;warning&#8217;, &#8216;err&#8217;
and &#8216;debug&#8217; and ZoneMinder uses these priorities when generating
the corresponding class of message. Standard facilities include
&#8216;mail&#8217;, &#8216;cron&#8217; and &#8216;security&#8217; etc but as
well this, there are eight &#8216;local&#8217; facilities that can be used by
machine specific message generators. ZoneMinder produces it&#8217;s messages
via the &#8216;local1&#8217; facility.</p>
<p class=MsoPlainText>So armed with the knowledge of the priority and facility
of a message, the syslog.conf file can be amended to handle messages however
you like.</p>
<p class=MsoPlainText>So to ensure that all ZoneMinder messages go to a
specific log file you can add the following line near the top of your
syslog.conf file</p>
<p class=Command># Save ZoneMinder messages to zm.log#</p>
<p class=Command>local1.*<2A><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> /var/log/zm/zm.log</p>
<p class=MsoPlainText>which will ensure that all messages produced with the
local1 facility are routed to fhe /var/log/zm/zm.log file. However this does
not necessarily prevent them also going into the standard system log. To do
this you will need to modify the line that determines which messages are logged
to this file. This may look something like</p>
<p class=Command># Log anything (except mail) of level info or higher.</p>
<p class=Command># Don't log private authentication messages!</p>
<p class=Command>*.info;mail.none;news.none;authpriv.none;cron.none<6E><65><EFBFBD><EFBFBD><EFBFBD>
/var/log/messages</p>
<p class=MsoPlainText>by default. To remove ZoneMinder messages altogether from
this file you can modify this line to look like</p>
<p class=Command>*.info;local1.!*;mail.none;news.none;authpriv.none;cron.none<6E><65><EFBFBD><EFBFBD>
/var/log/messages</p>
<p class=MsoPlainText>which instructs syslog to ignore any messages from the
local1 facility. If however you still want warnings and errors to occur in the
system log file, you could change it to </p>
<p class=Command>*.info;local1.!*;local1.warning;mail.none;news.none;authpriv.none;cron.none<6E><65><EFBFBD><EFBFBD>
/var/log/messages</p>
<p class=MsoPlainText>which follows the ignore instruction with a further one
to indicate that any messages with a facility of local1 and a priority of
warning or above should still go into the file.</p>
<p class=MsoPlainText>These recipes are just examples of how you can modify the
logging to suit your system, there are a lot of other modifications you could
make. If you do make any changes to syslog.conf you should ensure you restart the
syslogd process or send it a HUP signal to force it to reread its configuration
file otherwise your changes will be ignored.</p>
<p class=MsoPlainText>The discussion of logging above began by describing how
scripts produce error and debug messages. The way that the binaries work is
slightly different. Binaries generate information, warning and error messages
using syslog in exactly the same way as scripts and these messages will be
handled identically. However debug output is somewhat different. For the
scripts, if you want to enable debug you will need to edit the script file
itself and change the DBG_LEVEL constant to have a value of 1. This will then
cause debug messages to be written to the &lt;script&gt;.log file as well as
the more important messages. Debug messages however are not routed via syslog.
Scripts currently only have one level of debug so this will cause any and all
debug messages to be generated. Binaries work slightly differently and while
you can edit the call to zmDbgInit that is present in every binary&#8217;s &#8216;main&#8217;
function to update the initial value of the debug level, there are easier ways.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Use debug. ZoneMinder has various debug in it that by default
will go into your system log (via syslog). These will be of the form of</p>
<p class=MsoPlainText style='margin-left:36.0pt'>&quot;Sep 14 14:50:11
localhost zma-0[1975]: INF [Front: 221000 - Processing at 4.26 fps ]&quot;</p>
<p class=MsoPlainText>where the zma-0 part identifies the daemon and the device
it is running on. Entries with INF in are informational and not an error, if
you see ERR then it is one, though not all are fatal. WAR would indicate a warning.
You can prevent this information from being emitted by setting the
ZM_DBG_LEVEL_zmc environment variable to -1 or less once things are working. If
you want to run any of the daemons from the command line to test, setting
ZM_DBG_PRINT to 1 will output the debug on the console. You can also use the
USR1 and USR2 signals to increase or decrease the amount of debug being
emitted.</p>
<p class=MsoPlainText>The best places to look for errors are in the system
error log (normally /var/log/messages on RedHat), the ZoneMinder logs, and the
web server log (/var/log/httpd/error_log unless otherwise defined). There
should be something in one of those that gives you some kind of tip off.</p>
<p class=MsoPlainText>Some other things you can check.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Device configuration. If you can't get your cameras to work in
ZoneMinder, firstly make sure that you have the correct settings. Use xawtv or
something like that to check for settings that work and then run zmu -d
&lt;device&gt; -q -v to get the settings. If you can't get them to work with
that then the likelihood is they won't work with ZoneMinder. Also check the
system logs (usually /var/log/messages) for any video configuration errors. If
you get some and you're sure they're not a problem then switch off
ZM_STRICT_VIDEO_CONFIG in zmconfig.pl or the &#8216;options&#8217; tab.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Start simple. Begin with a single monitor and single zone. You
can run the zmc capture daemon from the command line as 'zmc --device
&lt;device&gt;' (or whatever your video device is). If it returns immediately
there's a problem so check the logs, if it stays up then your video configuration
is probably ok. To get more information out of it use debug as specified below.
Also check that the shared memory segment has been created by doing 'ipcs -m'.
Finally, beware of doing tests as root and then trying to run as another user
as some files may not be accessible. If you're checking things as root make
sure that you clean up afterwards!</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Web server. Ensure that your web server can serve PHP files. It's
also possible that your php.ini file may have some settings which break
ZoneMinder, I'm not a PHP guru but setting safe mode may prevent your PHP files
from running certain programs. You may have to set configuration to allow this.
Also since the daemons are started by your web server, if it dies or is shut
down then the daemons may disappear. In this version the daemons are run under
the control of a script which should trap expected signals but it is possible
this doesn't cover all circumstances. If everything else works but you
can&#8217;t get images in your browser a likely cause is a mismatch between
where your web server expects to execute CGI scripts and where you have
installed the zms streaming server. Check your server configuration for the
correct CGI location and ensure you have supplied the same directory to the
ZoneMinder configure script via the &#8211;with-cgidir option. </p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>One of the more common errors you can see in the log files is of
the form 'Can't shmget: Invalid argument'. Generally speaking this is caused by
an attempt to allocate an amount of shared memory greater than your system can
handle. The size it requests is base on the following formula, ring buffer size
x image width x image height x 3 (for 24 bits images) + a bit of overhead. So
if for instance you were using 24bit 640x480 then this would come to about 92Mb
if you are using the default buffer size of 100. If this is too large then you
can either reduce the image or buffer sizes or increase the maximum amount of
shared memory available. If you are using RedHat then you can get details on
how to change these settings at <span class=Internetlink><a
href="http://www.redhat.com/docs/manuals/database/RHDB-2.1-Manual/admin_user/kernel-resources.html">http://www.redhat.com/docs/manuals/database/RHDB-2.1-Manual/admin_user/kernel-resources.html</a></span>.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>You should be able to use a similar procedure with other
distributions to modify the shared memory pool without kernel recompilations
though in some cases this may be necessary. You can also sometimes get shared
memory errors if you have changed the monitor image size for instance. In this
case it is sometimes that an old process is hanging onto the shared memory and
will not let it be resized. Ensure that you do a full ZoneMinder restart and/or
manually delete the shared memory segment to check. Use the ipcs and ipcrm
system commands to check and remove segments if necessary.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>If you get odd javascript errors and your web console or other
screens come up with bits missing then it's possible that there is a problem
with the PHP configuration. Since version 0.9.8 ZoneMinder has used short PHP
open tags to output information, so instead of something like this '&lt;?php
echo $value ?&gt;', it will be something like this '&lt;?= $value ?&gt;' which
is easier and quicker to write as well as being neater. More information about
this directive can be seen at the following location, <span class=Internetlink>http://www.php.net/manual/en/configuration.directives.php#ini.short-open-tag</span>.
However although by default most PHP installations support this form, some will
need to have it switched on explicitly. To do this you will first need to find
your php.ini file (do a 'locate php.ini' or 'find / -name php.ini'. Be aware
however that sometimes you might find more than one, so ensure you identify the
one that is actually being used. You will then need to find the line that
starts 'short_open_tag = ' and change the Off value to On. This will correct
the problem. However in some cases you may have explicitly switched it off, so
that XML compliant documents can be more easily served, or you may even not
have permission to edit the file. In this case you can go into the web
directory of ZoneMinder and run 'sh retag.sh' which will replace all the short
open tags in the files themselves with the longer variant. You will obviously
have to remember to do this for each subsequent version of ZoneMinder that you
install as well.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Paths. I admit it, the various paths in ZoneMinder can be bit of
a nightmare mainly because some relate to real directories and others to web
paths. Make sure that they are all correct and that permissions are such that
the various parts of ZoneMinder can actually run.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Missing perl modules. There are various perl modules used by the
various scripts. If you get errors about missing ones, the easiest way to
install them is to type the following (you will probably need to be root),</p>
<p class=MsoPlainText style='margin-left:21.3pt'><i>perl -MCPAN -eshell</i></p>
<p class=MsoPlainText style='margin-left:21.3pt'>this will then (eventually,
after some configuration if it&#8217;s your first time) present you with a
prompt. From there you can type install module, e.g. Archive::Zip and the rest
should be more or less automatic as it will chase any dependencies for you.
There may be some initial configuration questions it might ask you on startup
if you've never run it before and to speed things up I would not install a new
Bundle at this point (it can end up building you a whole new perl if
you&#8217;re not careful) if it asks you but everything else should be quite
straightforward. You can often also install perl modules via your ordinary
package manager, e.g. yum or apt.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Unsupported palettes. ZoneMinder currently is designed to use the
simple palettes of greyscale and 24 bit as well as now the YUV420P and some
other palettes. This should cover most cameras but it's possible that there are
ones out there that might want to use more esoteric formats that ZoneMinder
doesn&#8217;t support. This will often show up as the capture daemon being unable
to set picture attributes. If this occurs try using different palettes starting
with greyscale and if you can't get anything to work let me know and I'll try
and add it.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>USB bus problems. If you have multiple USB cameras on one bus
then it can appear as if ZoneMinder is causing your cameras to fail. This is
because the bandwidth available to cameras is limited by the fairly low USB
speed. In order to use more than one USB camera with ZoneMinder (or any
application) you will need to inform the driver that there are other cameras
requiring bandwidth. This is usually done with a simple module option. Examples
are usb_alt=&lt;n&gt; for the OV511 driver and cams=&lt;n&gt; for CPIA etc.
Check your driver documentation for more details. Be aware however that sharing
cameras in this way on one bus will also limit the capture rate due to the
reduced bandwidth.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Incorrect libjpeg.a detection. It seems to be the case that in
some cases the library file libjpeg.a is reported as missing even when
apparently present. This appears to actually be down to the g++ compiler not
being installed on the host system. Since ZoneMinder contains both C++ and C
files you need to be able to compile both of these file types and so usually
need to ensure you have gcc and g++ installed (though they are often the same
binary).</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Httpd and zms memory leaks. It has been reported by some users
with RedHat 9 that the zms process fails to terminate correctly when the
controlled window is killed and also that it, and it&#8217;s associated httpd
process, continue to grow in memory size until they kill the system. This
appears to be a bug in early versions of<6F> apache 2. On other systems it may
appear that zms is leaking and growing. However what grows is the total and
shared memory size while the non-shared memory size stays constant. It's a
little odd but I think what it happening is that as zms picks images out of the
shared memory ring buffer to display, as each slot is read the size of that bit
of memory is added to the shared memory total for the process. As streamed images
are not read consecutively it's a semi-random process so initially most of the
buffer slots are new and the shared memory size grows then as time goes on the
remaining unaccessed slots reduce until once all have been read the shared
memory use caps out at the same size as the actual segment. This is what I
would have expected it to be in the first place, but it seems to do it
incrementally. Then once this total is hit it grows no further. As it's shared
memory anyway and already in use this apparent leak is not consuming any more
memory than when it started.</p>
<p class=MsoPlainText>Also, if you are using IE under Windows and get lots of
annoying clicks when various windows refresh then you'll need to edit your
registry and remove the value for HKEY_CURRENT_USER\AppEvents\Schemes\Apps\Explorer\Navigating\.current

<p class=MsoPlainText>Major architectural changes as well as a whole raft of
other enhancements and fixes.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Zones can now be (virtually) any shape of
polygon. This means that triangular, octagonal, duo decahedrons etc are now
supported. The only exceptions to this are self-intersecting shapes which will
be flagged. This adds a lot more flexibility to the definition of zones. Zones
can be drawn semi-interactively.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Certain preset zones settings are now supplied to
allow quicker configuration of zones. These are intended to be a guide only,
and not definitive settings but form a useful starting point.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; The zmpkg.pl scripts now attempts to determine
the supported syntax of the &#8216;su&#8217; command so it should work even
with distributions like Slackware that don&#8217;t support the &#8211;shell
option. Previously this required a hand edit.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Some common perl functionality has been moved to
perl modules which have been included. This also allows other scripts to use
the ZoneMinder modules to create additional functionality particularly in the
area of triggering. All scripts have been converted to use these modules.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; A (small currently) number of monitor presets
have been added to the monitor configuration view. This allows quicker initial
configuration of certain (mostly network) cameras without having to know all
the paths. Contributions detailing other cameras will be gratefully accepted.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Signal loss on locally attached video sources is
now detected. This will create a short Signal Lost event on signal loss,
followed by a Signal Reacquired event when it comes back. While the signal is lost
no recording will take place in any mode.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; The zmtrigger.pl script has been completed
revamped to support both incoming and outgoing triggers. Certain example
triggers and connections have been included in the trigger modules but this is
intended to be an example only and to provide a basis for users to customise
and add their own functionality. Users will also be able to contribute modules
tailored to specific external systems.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; The configure script now takes a generic
&#8216;extra libs&#8217; option to allow specification of any extra libraries
that may be required for compilation due to additional ffmpeg options etc. The
mp3lame option has been removed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Mime support for streaming has been enhanced to
allow easy configuration of additional formats of data streaming. The streaming
daemons themselves have also been improved to support the generation of other
stream formats.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; The alarm sound that can be configured to play
when viewing a monitor with a current alarm has now been improved to not depend
on the refreshing of the status which resulted in clipped audio.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Script debug now follows the same format as all
debug and uses the syslog facility. This means that all important messages go
into the /var/log/messages file (or equivalent). This can be modified by
redirecting the local1 facility in syslog.conf to go elsewhere, or be ignored,
if so desired.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; A new raw streaming format has been added for
live monitor streams. This produces a low cpu impact raw rgb feed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; A zm.pid file is now placed in /var/run/zm when
ZoneMinder is running, and removed when stopped. This can be used by other
elements to check the status of ZoneMinder. The pid in the file is that of the
master zmdc.pl server instance.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; The continuous/triggered settings for monitors
have now been removed. They have been replaced by an Enabled flag that
indicates whether a monitor is actually doing the task assigned to it. This can
be used by scripts to disable or enable monitors depending on external triggers
without having to change the Function or start and stop daemons. The state of
this flag is now saved in &#8216;run states&#8217; to allow ZoneMinder to be
started with some monitors initially disabled.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

re-organised slightly and some fields have moved between tabs.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; When motion is detected the centre of the region
of motion is written to shared memory, where is can be used for tracking. This
can now optionally be a simple median of the motion extents or (in blob mode) a
weighted centre for better location of irregularly shaped events.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Added event progress and navigation bar to event
view (currently not on IE). This allows partial replay of events and an
indication of how far through the event it is. This is off by default for low
bandwidth settings as the image replay tends not to be able to keep up.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Added --with-libarch to configure for 64 bit

versions of system libraries.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span></span>Release
1.21.4</a></h2>
<p class=MsoPlainText>A whole bunch of improvements and fixes.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; The video generation interface has been
redesigned and expanded. This allows you to see what videos have been generated
previously and manage, view or download them. You can also specify more
precisely what input and output options to pass to ffmpeg and what video
formats you want to support. These options are available from the
Options-&gt;Tools view.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Historical video is now supported from the XHTML
mobile device interface allowing you to replay previous events etc.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; A new timeline view has been added. This is an
enhanced graphic activity view that represents events as colour coded bars on a
time based chart. Passing your mouse over the activity will display images and
details from the events in the chart. You are able to choose whether you see
this view or the traditional events view as a default. Since this view can be a
large file and dynamic loading of event images can be bandwidth intensive this
preference can be specific on a bandwidth specific basis. The option to switch
between the traditional list and the timeline view is available at all times however.
IMPORTANT NOTE: This view is a beta version only and due to extensive use of
CSS currently only renders correctly on FireFox type browsers. Even then as it
can use huge numbers of elements it is possible it may degrade or crash your
browser. Specifically Internet Explorer seems to get totally confused and
renders some elements twice and others in the wrong place etc. I hope to remedy
this situation for the next release but for now using this view with IE is not
recommended.<2E> </p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; References to the video device files are now
expressed as full file paths rather than just numbers. This allows files other
than /dev/videoX to be used easily.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; Integration with all versions of ffmpeg, including
CVS, is now supported. At least until the next ffmpeg interface change anyway!</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Monitors can now use a file path as a video
source. This allows you to use scripts such as wget or other webcam type
applications to generate your images which can then be fed into ZoneMinder as a
monitor and analysed and archived etc.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Users can now be defined with a maximum bandwidth
setting. This prevents low privilege users from swamping the system with lots
of high bandwidth streaming.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Debug levels for the binaries can now be
controlled in a limited fashion from the Options screen. For more details see
the help on the Options-&gt;Tools-&gt;ZM_EXTRA_DEBUG* options.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; The user authentication methods have been revised
to separate authentication at the web front end from authentication at back end
streaming. Thus there are now several more authentication options to allow more
fine control. The most significant of these ZM_AUTH_TYPE now offers a choice of
&#8216;remote&#8217; authentication which allows you to use a third party
authentication scheme such as http basic authentication and have that users
name passed via the REMOTE_USER environment variable. Providing there is a user
of that name known to ZoneMinder they will be automatically logged in. Be
warned however that there is no facility for this user to log out so ensure
that you do not lock yourself into a low privilege account. Also you may need
to remove user cookies when you change authentication methods.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Users now have a &#8216;control&#8217; permission
which determines whether they are able to control PTZ style cameras. As with
the other permissions there are three levels, None, View and Edit. Unlike some
of the other options it may not be obvious what levels do what. The
&#8216;None&#8217; level bars access to any control functionality, the
&#8216;View&#8217; level permits users to actually control the positioning and
settings of a camera (rather than just look at them which is what might be
expected) and the &#8216;Edit&#8217; level allows users to modify the various
control capabilities.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; A bug was fixed where the streamed images were using
the quality settings for saved files.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; Jpeg errors are now reported via the generic
ZoneMinder error and debug mechanism rather than just to standard output as is
the default in libjpeg.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; The time taken to load and refresh the console view
has been reduced. This is especially significant where you may have lots of
monitors.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; Paths to the control scripts were hard coded with a
full path. This broke the packaged ZoneMinder distributions so the paths are
now relative to the ZM_PATH_BIN config unless they start with a
&#8216;/&#8217;.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; The masks used for shared memory have now been
refined to prevent invalid values from causing duplicates.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Monitors can now be re-ordered from the console
view to allow you to choose how you would like them arranged.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Motion detection can now be temporarily disabled
from the watch view. This is most useful with PTZ type cameras where you can
switch off motion detection whilst repositioning the camera. Just don&#8217;t
forget to switch it back on again afterwards!</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; A default scale per bandwidth setting can now be
defined. This allows you to reduce the size of streams etc on slow connections.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Monitors can now be defined with a default scale.
This allows you to reduce the viewing size of a monitor that might be capturing
at a large image size. This works in conjunction with the bandwidth specific
scaling so if you bandwidth setting is 50% and your monitor is also 50% then at
that bandwidth you will be viewing at 25%. This is to ensure that all monitors
maintain relative scaling at all bandwidths.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; The choice of streaming versus stills views as
default can now be specified per bandwidth setting.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; In the past there has been some confusion about
what the &#8216;prev&#8217; and &#8216;next&#8217; options do when scrolling
through events. They actually move to the previous or next event in the list
from which the event was selected rather than in chronological order.
Previously this order was descending date/time in most cases meaning that the
previous event would be one that occurred after the current event. In order to
prevent this confusion and allow users to define a default order which they
prefer there are now two more options in Options-&gt;System called
ZM_EVENT_SORT_FIELD and ZM_EVENT_SORT_ORDER which allow you to choose your own
sort type and order. The default for these is now date/time ascending meaning
oldest first which is opposite to the previous default and you will need to
update these options to retain the previous behaviour. Note also that this
ordering applies only to event lists and not the &#8216;last x events&#8217; in
the watch window which are still newest first.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; A curious problem with logging in on PHP 4.4 has now
been fixed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Following requests and some confusion about how
often filters are executed versus reloaded from the database, this is now a
configurable options (Options-&gt;System-&gt; ZM_FILTER_EXECUTE_INTERVAL).
Please read the help on this option for guidance on what values to use.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; A &#8216;Filters&#8217; button has been added to
the main console view allowing easier access to the filters view.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Support for the HTTPS protocol has been added
allowing streaming etc to function over secure links.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Following virtual extinction of donations I have
added a small one time nag screen which invites you to donate to ZoneMinder
after a month of use. That&#8217;s all it does and once dismissed you will
never see it again!</p>

</span></span>LANGUAGE &#8211; A lot of new tokens have been added. These have
been included in all the language files in English. It would be appreciated if
anyone who is able to edit their zm_lang_xx_yy.php language files and translate
these tokens could email them back to me so I can include them in future
releases.</p>

<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; On some platforms there is no definition of the
&#8216;round&#8217; function. Previous versions of ZM have detected this and
included one if no other is present. However changes in 1.21.0 meant that this
did not always happen and the function went undefined. This has been corrected.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

</span></span>FEATURE &#8211; A custom title can now be added via the normal
Options dialog (ZM_WEB_TITLE_PREFIX). This title will be used in all browser
windows and allows you to distinguish between multiple ZM installations for
example.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Ordinarily ZoneMinder will resize the console
window to fit the number of monitors displayed. If you are using a tabbed
browser this can be a little irritating. A new option (ZM_WEB_RESIZE_CONSOLE)
has been added to control this behaviour.</p>

</span></span>FEATURE &#8211; Version 1.21.0 added support for events to be
labelled with Cause and Notes fields. However these could not be modified
directly from the web interface. This has been amended so that an
&#8216;Edit&#8217; link is now present in the events listing. Clicking on this
allows you to modify these fields for one or more events so they can be
identified as belonging to a particular incident.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; There has long been a dichotomy between the
functions that can be applied via interactive filters versus background saved
filters. This release addresses this to some extent allowing you, for instance,
to archive or unarchive matching events, or edit them as described above. This
is not a complete solution and it is expected that the functionality will
converge further in the future.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Previously in the c/c++ code accessor functions

expensive when done repeatedly so some classes used cached local variables to
avoid this. The configuration has been rewritten to provide all configuration
options as members of the configuration class which are initialised once on

</span></span>FEATURE &#8211; Events viewed in the events listing view can now
be saved locally by clicking on the &#8216;Export&#8217; button. This creates a
tar or zip file of the selected file groups, such as images, videos etc, as
well as, optional, HTML pages describing the basic details about the event and
frame details. This allows a basic navigation and viewing of the events outside
of the regular ZoneMinder interface. This format is different, and improved,
over that that created in the background filter function and it is expected
that these functions will converge at some point.</p>

</span></span>FEATURE &#8211; Several users have reported problems using the
Perl Compatible Regular Expression (PCRE) library, mostly to do with it not
being found or an incorrect version being used. This version allows an
alternative method of parsing the output from network cameras that does not depend
on libpcre at all. Which method is used is controlled by the option
Options-&gt;Network-&gt;ZM_NETCAM_REGEXPS. If this option is on then the
traditional regular expression based parsing is implemented, provided you have
built with libpcre. If the option is off or libpcre is missing then a more
basic parsing is used instead. This new method should be slightly faster as it
does not have the overhead of regular expression parsing, however this also
makes it slightly more inflexible. If you experience problems using the new
method with your netcam then you should try switching to the regular expression
based method, and report the issue via the forums, preferably with a snapshot
of the output of your camera.</p>

</span></span>FEATURE &#8211; In previous versions the events folder has been
keyed by the monitor name. This has caused problems in the past with various
characters appearing which are legal in names but not in filesystems. From this
version all files related to monitors are keyed on the monitor id rather than
the name. To help you navigate through these files the monitor name still
exists but as a link only. Please ensure you run zmupdate.pl to update your

which changed the interface that ZoneMinder uses and so broke compilation. This
version will detect which version of ffmpeg you have and compile accordingly.</p>

</span></span>FEATURE &#8211; An experimental feature has been added which lets
you view several events in sequence. In event listing you can check the events
you want to view and then click the &#8216;View&#8217; button. This will allow
you to navigate through only those events in the normal manner (via Prev and
Next links) but also to view them in sequence by clicking on the &#8216;Play
All&#8217; link. This will replay each event and then automatically move onto
the next one. You can stop this progression at any time by pressing
&#8216;Stop&#8217; (which only stops the sequence and not the currently playing
event). The timing of the replay is done depending on the calculated length of
the event (plus one second) and so may not exactly correspond to the real event
length. In particular this is unlikely to work if replaying events using MPEG
video and buffering players as the timing will likely be incorrect. If you are
viewing an event but haven&#8217;t checked any in the list the &#8216;Play
All&#8217; button will just work down the current event list.</p>

</span></span>FEATURE &#8211; Previously events have been created even if only
one frame has generated an alarm. This has not always been desirable as
sometimes glitches and flickers create large numbers of events, however no
mechanism existed for limiting this. In this version you can now specify the
minimum number of consecutive alarmed frames that are necessary to create an
event. This is the &#8216;Alarm Frame Count&#8217; described above. Note that
if an alarm is in progress single isolated alarmed frames will still prolong it
and the count only applies to the initial frames that would cause the event.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; All stills views now use the single image mode of
zms rather than spawning off a zmu process to write an image which is then
read. This reduces complexity of double buffering significantly and also
reduces the chance of errors caused by multiple simultaneous image generation.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; The generated MIME types when creating streamed
video were previously assigned by zms depending on which of a limited number of
output formats was specified. This has now been changed so that the ffmpeg
libavformat library itself now generates these identifiers. The consequence of
this is that many more video formats supported by your version of ffmpeg should
now be available via zms.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; When viewing a single frame of an event you can
select a &#8216;stats&#8217; link to view the statistics that apply to that
frame, if you have the RECORD_EVENT_STATS option switched on. This can be used
to help configure your zones for optimal motion detection. Previously only
pixel count values were displayed here which made it difficult to configure
zones configured in percentage terms. These values are now displayed in both
pixel and percentage terms to assist in zone configuration. Note that the
percentage values are based on the current size of the zone so if this is
changed then the value displayed will not be applicable at the time of event
generation.</p>

</span></span>FIX &#8211; When doing motion detection an extra blob, that could

<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; A problem was reported whereby when using bulk frame
records to reduce database load the last frame record was not written.
Replaying the event via the web interface resulting in the event being
truncated. A correction has been made so prevent this and ensure that the last
frame of an event is always recorded.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; If an analysis daemon terminates abnormally or the
host computer crashes then events can be left in a state whereby they
effectively have zero length and are useless. A change to zmaudit.pl was made
such that any &#8216;open&#8217; events such as this which have not been
updated for at least five minutes are closed and updated to reflect their
actual content so that they may be viewed or saved. Events recovered in this
way are named with a &#8216;(r)&#8217; mark to help identify them.</p>

</span></span>FIX &#8211; In more recent versions of MySQL the password hash
generated is 50 characters long, which overflows the previous password field in
the database which was only 32 characters long. This field has been extended to
64 characters to accommodate this.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

referenced.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FIX &#8211; The default, bandwidth specific, rate and scales were
not always used as the records in the database were misnamed. This is now

these will be lost if they had been changed.</p>

</span></span>FIX &#8211; It was previously the case that old images could be
left in the &#8216;images&#8217; directory for a long period, sometimes
resulting in incorrectly assuming correct operation. A fix was made to
zmaudit.pl which modified the previous clean up of old WAP images so that any
old images left in this directory are removed after a short period. Please
ensure that if you have customised the web interface and have images you wish
to keep that they are not left in the temporary images folder as they will now
be deleted.</p>

</span></span>FEATURE &#8211; The default replay rate and live and event scale

<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Two new filter elements have been added. These
are disk blocks and disk percentage. These are event independent and return the
amount of disk space used on the event partition in terms of disk blocks or
percentage as returned by <i>df(1)</i>. Thus filters using these criteria will
either match all events or none at all depending on the disk usage at the time
of filter execution. The addition of these terms along with the ability to sort
and limit filter results now means it is possible to create a filter that will
automatically clear out old events once disk usage exceeds a certain value. Included
in the database schemas for both new installations and upgrades is a sample
filter called PurgeWhenFull which can be used to do this. It is initially not
set to do anything automatically so if you want to use it, you should load it
into the filter selection window, modify it to your taste and then save it,
selecting &#8216;auto delete&#8217;. Please note that filters created using
disk related terms to delete events should always contain a limit term also
otherwise it is possible for all events to match and thus be deleted. Using a
limit ensures that only a small number are affected at any one time.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FEATURE &#8211; Filters can now be defined to automatically
execute an external script or program of your choosing. This can be specified
when the filter is saved. Note that for security reasons this cannot be just
any arbitrary command but must be readable and executable by your web server
effective user. The script or program you specify here will be executed in the
events root directory once for each event and will be passed one parameter
containing the relative path to the event directory. This will normally be of
the form <i>&lt;MonitorName&gt;/&lt;EventId&gt;</i> so it it possible to
determine both the monitor and event in question from the path. Note also that
a flag is set per event as with other auto actions indicating that an
executable script has been run on that event and so to exclude it from
subsequent matches. However if you have several filters all with executable
scripts you will find that only the first gets executed as the flag will be set
following successful completion and so no further scripts will be run on that
event. Successful completion is indicated by the script returning a zero exit
status, any other status indicates an error and the <i>executed </i>flag will
not be set.</p>

selecting the various types of zones etc only disables those options you no

<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>MPEG video streaming. ZoneMinder now supports true video
streaming if configured with the <i>&#8211;with-ffmpeg</i> option. This allows
one or both of live or event streaming to be in this format rather than motion
JPEG style as before. Note however that is still somewhat experimental and may
not work on your system. The reason for this is due to the variation in plugins
and video movie formats. Currently I have got it working well with browsers on
Windows platforms using the Windows Media Player plugin and the 'asf' video
format. I have also managed to get event streaming working on Mozilla using
mplayer (I think) though it jumps in and out of it's place in the window a bit.
I would appreciate any feedback or advice on formats and plugins that work on
your system. Also note that video streaming tends to get buffered before being
displayed. This can result in the 'live' view being several seconds delayed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Motion JPEG Capture. Previously image capture from network
devices has been limited to single stills capture only. This has now changed
and if you entered a remote camera path that returns the <i>multipart/x-mixed-replace</i>
MIME type then this will be parsed and images extracted from the stream. This
is much faster than before and frame rates can be as fast now with network
cameras as with capture cards and video. This feature also has the side-effect
that one ZoneMinder installation can use another as a remote video source.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>NPH Streaming. After months of frustration I have finally figured
out why streams were corrupted using Cambozola versions after 0.22. It turned
out that apache was injecting characters into the streams which was screwing up
the headers. I believe this to be because the initial header had no
content-length header, as the length is indeterminate. So I have added a zero
content length header which I believe fixes the problem though perhaps not in
the best way. I have also made the installation link the existing zms binary to
nph-zms so that you can now use zms in non-parsed-header mode. If it detects it
is in this mode then the content-length header is not output, though several
other additional ones are. In nph mode the false character injection seems to
disappear so I suspect this is a better way to use zms.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Bulk Frame Records. With the recent advent of the 'Record' and
'Mocord' modes a lot of people have started using ZoneMinder as a pseudo-DVR.
This meant that a lot of database activity was taking place as each captured
frame required its own entry in the database. The frames table has now been
reorganised so that 'bulk' frames may be written at defined intervals to reduce
this database activity. The records act as markers and individual frame timings
are interpolated in between. Bulk frames are only used when no alarm or motion
detection activity is taking place and normal frame records are kept otherwise.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Event List Ordering and Scrolling. It was previously the case
that the &#8216;Next&#8217; and &#8216;Prev&#8217; buttons on the event view
did not always go to the event that was expected and sometimes disappeared
altogether. This behaviour has now been modified and these buttons will now
take you to the next and previous events in the list which the event was
selected from. Thus if the list was sorted on ascending scores then the
&#8216;next&#8217; event is the one below which has a higher score etc. A
possibly counterintuitive side effect of this is that as the default list is
sorted by descending time the &#8216;next&#8217; event is the one below in the
list which will actually be earlier and the &#8216;previous&#8217; event is
later. So long as you remember that next and prev refer to the order of the
list you should be ok.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Zone Percentage Sizes. Zone motion detection parameters can be
defined either in terms of total pixels or as a percentage. This percentage was
defined relative to the size of the image as a whole. However this was
difficult to calculate or estimate especially with several zones of varying
sizes. In version 1.19.0 this has been changed so that the percentage relates
to the size of the zone itself instead. This should make calculations somewhat
easier. To convert your existing zones you can run zmupdate.pl with the
&#8211;z option, though this should be done only once and you should backup
your database beforehand in case of error.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Console View System Display. The console display was slight
revamped to indicate disk space usage (via the &#8216;df&#8217; command) on the
events partition,</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

</span></span>Zone Form Validation. Changes applied in version 1.18.0 to
prevent invalidate entries in the zone definition form actually had the
opposite effect due to JavaScript treating everything as a string and not a
number (e.g. 5 is greater than 123). This is now corrected.</p>

</span></span>Frame Buffer Size. Previously it was possible for frames being
sent from the analysis daemon to the frame server to exceed the defined maximum
buffer size in which case the write would fail. It is now possible to define a
larger size if necessary to prevent this. Note that you may have to adjust your
system configuration to accommodate this. For further details check the help
for the ZM_FRAME_SOCKET_SIZE option.</p>

</span></span>Filter Name Duplication. Following recent changes to the filters
table, several people reported that when saving filters they actually got a
duplicate. This resulted in several copies of filters all with the same name as
the constraint on unique filter names was not present. Well it is now so when
upgrading your database all the filters will be renamed from &#8216;myfilter&#8217;
to &#8216;myfilter_&lt;id&gt;&#8217; where &#8216;&lt;id&gt;&#8217; is the id
number in the database (which is then removed). In general the higher the id
number the more recent the filter. So you should go through your filter list
deleting old copies and then rename the last one back to it&#8217;s original
name.</p>

a particular monitor has now been removed and you may be left with several
filters all doing the same thing to all of the events or have filters which for
instance delete events on only one monitor but which now would delete them for
all of them. It is recommended that you review your list of saved filters and

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Optimisations and Performance Improvements. This release contains
several major performance improvements in various areas. The first of these is
that image processing for YUV style input formats are now pretty much handled
at almost the same speed as native RGB formats. As this is what the capture
daemons spend most of their time doing, the improvement helps reduce the amount
of CPU time by a significant degree. Application of these changes also
highlighted a bug that had existed previously in YUV conversion which caused
incorrect conversions for certain values. The other two main areas of
optimisation are in the Blend and Delta image functions. Normally when doing
motion detection the analysis daemons spend about 99% of their time comparing a
captured image with the reference image and then blending the two ready for the
next capture. Both of these functions have been significantly improved. In
previous versions there were two options for calculating image deltas (or
differences), a simple RGB average and a Y channel calculation. Historically
the RGB one was faster however with the optimisations the Y channel calculation
(which is more accurate) is now 15-20% faster and so has become the default
though you can select either method by the ZM_Y_IMAGE_DELTAS configuration
option. A new method of image blending has also been added which is up to 6
times faster than the old one which is retained for compatibility and because
in some unusual circumstances it may still be more accurate (see the
ZM_FAST_IMAGE_BLENDS option for details). Altogether these optimisations (along
with other common sense ones such as not maintaining a reference image in
&#8216;Record&#8217; mode where it is not used) significantly reduce the CPU
load for most systems, especially when alarms are not in progress. If an alarm
is detected then a lot of file system and database activity takes place which
is limited by the speed of these resources so the gain will not be as much.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Remote Authentication. This document has previously indicated
that basic authentication for network cameras could be used by entering a
hostname of the form of &lt;user&gt;:&lt;pass&gt;@&lt;hostname&gt;. This was
not actually the case as the relevant authentication header was never sent.
This is now fixed and addresses of this form can now be used.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Filter Date Parsing. The zmfilter.pl date parsing now correctly
reports when dates or times which it cannot parse are used.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Monitor Independent Filters. Previously filters were closely tied
to a monitor and a new filter had to be created for each monitor. This has now
changed and filters can now specify an associated monitor in the same was as
other parameters. Links have now been added to the main console view to allow
you to view lists of events from all monitors in one and saved filters can now
affected as many or as few monitors as you wish. IMPORTANT: Please note that as
part of the upgrade process all your filters will have any automatic actions
unset. This is because the previous affinity to a particular monitor has now
been removed and you may be left with several filters all doing the same thing
to all of the events or have filters which for instance delete events on only
one monitor but which now would delete them for all of them. It is recommended
that you review your list of saved filters and delete duplicates before adding

<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>New Filter Operators. Two new filter operators and their inverse
have been added. You can now indicate whether a value is in a set of other
values, for example &#8216;cat&#8217; is in the set of &#8216;cat, dog, cow,
horse&#8217;. You can also use regular expressions so &#8216;cat&#8217; matches
&#8216;^c.*&#8217;. The &#8216;not in set&#8217; and &#8216;not matches&#8217;
operators are also available.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Additional Scales. Enhancements to the scaling algorithm mean
that non binary scales are now just as easy to apply, thus new scales such as
0.75x have been added. Others can be easily included if necessary.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Montage Sizing. The montage view allows you to view all of your
active cameras in one window. However if your cameras are different sizes then
this becomes very untidy. You can now constrain the image size of each monitor
in this view to a fixed size with the ZM_WEB_MONTAGE_WIDTH and
ZM_WEB_MONTAGE_HEIGHT configuration options. Monitor images will be enlarged or
reduced as necessary.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Compact Montage. The traditional montage view includes individual
small menus for each monitor and a status display. This results in a somewhat
cluttered display and the refreshing of the status displays may generate more
accesses than desirable. Using the ZM_WEB_COMPACT_MONTAGE configuration option
allows this montage view to only include the monitor streams and one overall
menu bar with no status displays.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Monitor Name Constraint. The name given to a monitor is used in
file paths and several other areas. Thus it is important that it follows
certain conventions but up until this release these names were unrestricted.
The monitor form now limits monitor names to alphanumeric characters plus
hyphen and underscore.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Timestamp Change. Traditionally ZoneMinder has time-stamped each
image as it is captured. This ensures that all images have their capture time
recorded immediately. However there are several side-effects which may be
undesirable. Firstly the time and resource is spent time-stamping images that
are not recorded and which are discarded, secondly the timestamp is included in
any motion detection and may potentially trigger an alarm if detection
parameters are very sensitive. The third effect is that as the timestamp is
added to the image at it&#8217;s native resolution, if the image is scaled then
the timestamp is scaled also. This may not be a problem for enlargement but if
the image size is reduced then it may become illegible. This version now allows
you, via the ZM_TIMESTAMP_ON_CAPTURE configuration option, to indicate whether
the timestamps should be added on capture, as before, or only added when the
image is viewed or recorded. Setting it to this later value allows timestamps
to be added to scaled images. This is little performance impact either way.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Scaleable Stills View. The stills view of a monitor (when
streaming is not available or desired) is now scaleable in the same way as the
streamed view.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Double Buffered Stills View. The stills view has now been
restructured to allow a double buffering approach. Thus a new image is loaded
in the background and only written to screen when complete. This removes the
refresh flicker that means that the screen blanks periodically however uses
more JavaScript so may not be suitable for all platforms. Whether ZoneMinder
uses double buffering or not is controlled by the ZM_WEB_DOUBLE_BUFFER
configuration option.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Fixed Length Event Bug. A bug was reported whereby the fixed
length events that could be specified for use in Record or Mocord mode could
sometimes result in events a multiple of that length. So events that were meant
to be 15 minutes long could sometimes be 30 or even 45 minutes. This was
especially the case with monitors that had low frame rates. This is now fixed.</p>

</span></span>Add Max Alarm Threshold. Previously the alarm threshold (which is
the amount a pixel has to differ from it&#8217;s counterpart in the reference
image) existed only in a &#8216;minimum&#8217; form meaning pixels that were
more different matched. A maximum has now been added to assist in screening out
large changes in brightness. In addition to this a number of new consistency
checks have been added to the zone definition form to try and prevent bogus or
invalid settings.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Diagnostic Zone Images. A regularly requested feature is that of
adding extra information to allow diagnostics of the process of image
detection. This has previously been somewhat hit and miss but in this version a
new configuration option ZM_RECORD_DIAG_IMAGES has been included to allow this.
This option will generate several images for each captured frame in an alarm
including each reference image and a series of images containing the image
differences at various stages in the process. It is not possible to record
these for the image prior to an alarm but those following it are included and
should assist in tuning the zones to provide optimal motion detection.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Event Images Renamed. The capture and analysis images recorded
during an event have been renamed from capture-???.jpg to ???-capture, and from
analyse-???.jpg to ???-analyse.jpg. This is to allow all images (including
diagnostic ones) to be associated with the frame sequence number more easily.
This means that old events will no longer be able to be viewed as the wrong
image will be being searched for. To avoid this you can use the new
&#8216;zmupdate.pl&#8217; utility to rename all your old images by doing
&#8216;perl zmupdate.pl &#8211;r&#8217; as an appropriately privileged or root
user.</p>

</span></span>Version checking. ZoneMinder will now optionally check for new
versions of itself at zoneminder.com. This is done with a simple http get and
no personal information otherwise than your current version of ZoneMinder is
transmitted or recorded. If new versions are found you may be alerted of them
via the web interface. This is an initial step towards enhancing and automating
the upgrade process.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Force Java. Previously ZoneMinder could be forced to override
it&#8217;s detection of browser capabilities to prevent the Cambozola Java
applet being used. However sometimes the opposite effect was desired and using
the applet was preferred to native image handling. This has now been made
possible by making the ZM_CAN_STREAM option tri-state allowing
&#8216;auto&#8217;, &#8216;yes&#8217; or &#8216;no&#8217; to be used to provide
all alternatives.</p>

<p class=MsoPlainText>Language changes and other enhancements.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Version Numbering. ZoneMinder version numbers have now changed.
This is to allow more frequent &#8216;point&#8217; releases which are expected
to happen for instance whenever new language files are included. Previously all
releases had the same version increment so it was difficult to tell the
significance of any particular release. Now the version number is in the <i>x.y.z</i>
format where a change in <i>x</i> signifies a major fundamental or
architectural rework, a change in <i>y</i> will indicate a new release
containing incremental feature changes or fixes recommend to all users and a
change in <i>z </i>will generally mean minor non-functional or critical
modifications which would not be recommended as important to all users. As
ZoneMinder has been referred to by the point release up until now, e.g. .15,
.16 etc the next number in that sequence has been retained for continuity and
to avoid having any ambiguity in version numbers.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Language Support. ZoneMinder now allows specification of system
and user specific languages other than UK English. These languages are given in
language files named zm_lang_<i>nn_mm</i>.php which can be created from the
default zm_lang_en_gb.php file. If your language is not included then please
consider doing a translation by checking this file and submitting your changes
back for inclusion in future releases.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Syntactic Improvements. Previously setting &#8216;NOTICE&#8217;
errors on in PHP would flag tens or hundreds of violations in the ZoneMinder
web files. Whilst not strictly errors this represented sloppy coding and
sometimes covered up genuine bugs. All the files have been revisited and
revised to ensure that a many of these problems as possible have been
eliminated and only the very few where the fix would be significantly less
optimal than the problem remain.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Stream Scaling Resizing. Previously when watching a stream and
modifying the scale of the streamed feed only the actual feed would change size
and the containing frames and windows would remain the same. This was fine for
changes to smaller scales but problematic for larger scales. This has been
changed for that the window and frames will now resize appropriately.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Mmap Return Value. A problem identified by users in the forum relating
to checking of return values from the mmap function call has been corrected.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Minor Bugs. A number of minor bugs and inconsistencies were
corrected.</p>
<h2><a name="_Toc125113522"><span style='text-decoration:none'>12.20.<span
style='font:7.0pt "Times New Roman"'>&nbsp; </span></span>Release 0.9.16</a></h2>
<p class=MsoPlainText>Major usability enhancement and fixes.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Run States. Instead of the old &#8216;start/stop&#8217; links the
current system state is now a link which takes you to a dialog which allows you
to start, restart or stop the system. You can also save the current run state
which basically takes a snapshot of the current monitor functions and saves
that. You can then reselect that state later which basically involves resetting
the monitors to have these saved functions and then doing a system restart.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>New Monitor Functions. Instead of Passive, Active, and X10, the
modes are now Monitor (= old Passive) which just allows you to watch the feed,
Modect (= old Active) which is MOtion DetECT and which will capture events as
previously, Record which continuously records with no analysis and MoCord which
is a hybrid of Modect and Record and which will continuously record but also do
motion detection and highlight where this has occurred. The Record and Mocord
functions both records events whose length in seconds is defined by the
'Section Length' monitor attribute. You can additionally specify a 'Frame Skip'
value to tell it to not record 'n' frames at a time, when not alarmed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>X10 Function removed. The X10 mode has been removed and replaced
by an indication of whether the monitor is 'continuous' or 'triggered'. This
basically just indicates whether it may be controlled outside of zmdc and
zmpkg. Additionally the X10 triggers may now be specified in an X10 section.
This has changed to allow for other types of triggers to be added more easily.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Paginated Event listings. The event listings are paginated by
default. You can list all of the events if you like by choosing the appropriate
option. There are shortcuts to pages of events at the top of the listing. If
these produce strange looking sequences like 1,2, 3, 5, 9, 17, 37 etc this is
deliberate and uses an exponential algorithm intended to allow you to quickly
navigate through the list to a particular page in the minimum number of clicks.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Scaleable Streams. Event and monitor streams can now be scaled to
a certain extent allowing you to view at a different resolution than that captured.
This area may be somewhat incomplete especially in terms of monitoring at a
higher screen size where the frame is not adjusted properly.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Variable Frame Rates. Event streams can now be viewed at various
rates allowing faster review (if your bandwidth allows) to long events, or
slower for more precision.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Scaleable/Variable MPEG generation. Generation of MPEG videos now
also allows you to specify the scale relative to the original image and also
the frame rate. Again, for long events captured in the perpetual recording
modes this will allow a faster review of the period the event covers.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Tabbed Monitor options. Specification and modification of
monitors is now in a tabbed form for easier navigation.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Additional stream headers. The stream headers have been changed
to hopefully ensure that they are less likely to be cached.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Maximum process restart delay. zmdc.pl now has an upper limit (15
minutes) to the time it waits before restarting continuously crashing
processes.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Intelligent Module inclusion. zmfilter.pl now includes
Archive::Zip and other modules on an as needed basis so won't complain about
them being missing unless they have been explicitly configured to be used.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Adaptive Watchdog. zmwatch now more adaptive to actual frame
rates.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Fixed zmfilter CPU sucking bug. zmfilter.pl will now restart on
failure to read shared memory. Previously this could go into a nasty CPU
sucking loop!</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>New zmconfig options. zmconfig.pl has a new option to run with no
database if necessary</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>File reorganisation. Various administrative file changes and
reorganisations.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Compiler warnings. Various tweaks and modifications to reduce
compiler and memory warnings.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>SQL Buffer size. Increased SQL buffer size to cope with large
pre-event buffers, plus a couple of other buffers have been enlarged.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Incorrect Frame time offsets. The time offsets in alarmed frames
were incorrect and based on the time of storage rather than capture. This gave
the impression that there was a delay after the first alarmed frame and messed
up some streaming timings. This has been fixed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Event Frame listing. You can now view details of the frames
captured such as their time and score etc by clicking on the scores in the
events views.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Refined shared memory handling. Fixed zmfilter, zmwatch and zmx10
to allow zero as a valid shared memory id to allow them to keep on working if
the segment has been marked for deletion</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Frame daemon stability. Changed image buffer in zmf to be static
rather than dynamic. This has made zmf much more stable.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>MPEG overwrite option. Fixed the 'Overwrite' checkbox in video
generation to actually overwrite the video. Modded the page slightly also.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Daemon control improved. Changing between monitor functions, e.g.
Modect, Mocord etc now restarts the correct daemons.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Improved time based filters. Filters that include time based
clauses now get executed regardless of whether new events are being generated.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Audit daemon started unconditionally. zmaudit is now started
regardless of the setting of FAST_DELETES as zmfilter depends on it being
there.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Filtering more active. zmfilter is now started in 'Monitor' mode.
It does not run in when monitors are completely off however.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Stills paged. The stills view of events is now paginated for
easier navigation.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Archive images optional. Normally when an alarm is detected a set
of raw images is saved along with a mirror set of images containing motion
highlighting. This second set can now optionally be disabled.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Settings in auth mode. Control of camera brightness, contrast etc
did not previously work when running in authorised mode. This is now fixed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>zms parameter bug fixed. The streaming server incorrectly parsed
and assigned one of it&#8217;s arguments. This is now fixed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>zmu brighness bug. Previously camera brightness was not correctly
parsed from command line options passed to zmu.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Event window width variable. Event windows now scale to fit the
event image size.</p>

style='font:7.0pt "Times New Roman"'>&nbsp; </span></span>Release 0.9.15</a></h2>
<p class=MsoPlainText>Various bug fixes from the last release and before.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Bandwidth. A bug was introduced in .14 which caused a corrupted
console display and manic refreshes on new installations. This was due to a
missing bandwidth setting when no existing cookie was detected. This is now
fixed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Again in .14 a problem occurred for a new release whereby
zmconfig wanted to know the database details and but also previously wanted to
access the database before it had asked the questions. This has now been
addressed though it does require that zmconfig is run twice initially, once to
created the scripts and once to import the configuration into the database.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>In association with the previous error, the zm_config_defines.h
file was not created in the absence of the database as this was what was used
to assign configuration ids. This now takes place regardless of the database.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>The SQL to create the Users table was mistakenly omitted from the
.12 database upgrade script this has now been corrected.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>A bug in zmfilter was pointed out whereby the dynamic loading of
the Zip or Tar archive modules depending on a preference actually wasn&#8217;t.
It was looking for both and loading both at compile time. This has now been
modified to be fully runtime.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>The database user definitions in the zmvideo script indicated one
database user while the database connection used a different one. This
prevented any videos being generated.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>A problem was found if using the zmf frame server and greyscale
images. The option to colourise JPEG images is intended to be used to ensure
that all JPEG files are written with a 24 bit colourspace as certain tools such
as ffmpeg require this. However in the circumstances described above images
written by zma directly were colourised whereas those written by<62> zmf
weren&#8217;t. A change has been made whereby if set all greyscale JPEG images
are colourised in all circumstances.</p>

<p class=MsoPlainText>Major new feature and important bug-fixes.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Web configuration. Following many requests and to make ZoneMinder
easier to administer the configuration system has been changed slightly. You
should now still run zmconfig.pl to specify an initial configuration but you
now only need to answer the first few questions to give a core set of options
including the database options. The remainder of configuration options can then
be ignored to start with and all but the core options will be written to the
database. You can then view and modify these options from the web interface and
apply then without recompilation, which is now only necessary if you change the
core configuration.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Following a number of requests the .sock file directory is now
configurable in zmconfig.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Y channel bug. When using colour cameras a motion detection
problem was present if fast RGB images deltas (ZM_FAST_RGB_DIFFS) was off. This
was an overflow error in the calculation of the Y channel and caused excessive
image differences to be calculated. This has now been fixed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>The use of the Term::Readkey perl module in zmaudit.pl has been
removed. This module had been removed from zmconfig.pl previously but had
lingered in this script.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>A bug was found in zmx10.pl causing a crash if time delayed X10
events were used. This has now been fixed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Removed use of &#8216;zmu&#8217; binary from zmwatch.pl and
zmx10.pl. Previously these scripts had used zmu to determine last image time
and alarm state information. The use of this script was a bit overkill and the
introduction of user permissions complicated matter slightly so these scripts
now access the shared memory directly.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Shared memory permissions. Following introduction of a user
permissions system the previous 777 mode for shared memory was deemed insecure.
Consequently from now on shared memory is only accessible from the owner. This
means that zmu will only work when run as root or the web user unless you set
it setuid where it should still be secure as it will require authentication.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>All SQL buffers in the C++ code have been enlarged. There was
previously an issue with a buffer overflow on certain occasions.</p>

not just read-only.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

</span></span>Shared memory has now been rationalised to prevent some common

this version on it will remove all old shared memory segments.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Fixed zone image map bug for percentage zones. When you had
defined a zone in percentage terms, the image map used to select it for editing
was broken. This is now fixed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>New contrast/brightness etc adjustments feature. This accessible
from the Settings link on the monitor window. It's fairly basic at present but
should work for most types of cameras. If you have any device or driver
specific auto-brightness, auto-contrast etc enabled the changes you make may
appear to work but may be overridden by the auto feature immediately so check
for that if your changes do not appear to be having an effect. Also if you have
a number of cameras being multiplexed onto one device then any changes here
will probably affect all your cameras.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Some redundant window scrollbars removed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Added user and access control. If enabled in config
(ZM_OPT_USE_AUTH) then you will need to define and login as ZM users. There
will be one users already defined, with username 'admin' and password 'admin'.
This user is defined will full permissions and clicking on the 'Options' link
from the main console window will allow you to modify and create users with
various permission sets which hopefully will satisfy most requirements. These
users (except any defined with 'system' edit capability) can be restricted to
certain cameras by adding the monitor ids as a comma-separated list (no spaces)
to the appropriate field. Users limited to specific monitors may not create or
delete monitors even if defined with monitor edit permissions.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Some windows now (optionally) use a JavaScript timeout to refresh
themselves rather than a refresh header. Since refresh headers were interrupted
if a link of the page was linked there were previously various forced refreshes
from child windows to restart the refresh process. By using JS refresh timers
which are not interrupted these extraneous refreshes have been mostly
eliminated.</p>

</span></span>Added image view to events lists. Again a partial implementation
of a suggested feature. If you click on the score column you will now get a
snapshot of the event frame with the highest score. This is to enable you to
quickly see what the event was about without having to watch the stream or view
all the static images.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Make delta times variable precision. A couple of problems had
been reported where long events got negative durations. This was due to an
overflow in a time difference routine. This had been operating on fixed
precision allowing high precision for short deltas. This routine has been
changed to allow variable precision and events will now have to be several days
long to wrap in this way.</p>

</span></span>Fixed round detection problem. Although the existence or
otherwise of the &#8216;round&#8217; function is correctly detected, the
appropriate header file with the results of this test was not included which
was not helpful. This has been corrected. </p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

modify the events directory to reflect this. This has now been fixed.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>OPT_MPEG bug. A bug was reported (by Fernando Diaz) where the

into the scripts. This now happens as intended.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Fixed zmvideo.pl event length bug. The zmvideo.pl script which is
used to generate video MPEG files tries to calculate the correct frame rate
based on the length of the event and the number of frames it contains.
Previously it did not take account of the pre and post event frames and so
passed a much shorter value to the mpeg encoder than it should. This will only
have affected short events encoded with ffmpeg but will have resulted in much
faster frame rates than necessary. This has now been corrected to take the
whole event length into account.</p>

</span></span>Fixed filter bug. A bug in the zmfilter.pl script was detected
and reported by Ernst Lehmann. This bug basically meant that events were not
checked as often as they should have been and many may have been left out for
filters that had no time component. The script has now been updated to reflect
Ernst&#8217;s suggested changes.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

</span></span>Stylesheet change. Previously the stylesheet didn&#8217;t really
work very well on Mozilla, Netscape and browsers other than IE. This turned out
to be because I was using HTML style comments in there instead of C style ones.
This has now been corrected so you should see the correct styles. </p>

</span></span>Zmconfig.pl ReadKey. Thanks to a ridiculously sensible suggestion
from Carlton Thomas this module has been removed from zmconfig.pl. Originally
Term::ReadKey was in there for funky single character unbuffered input but that
has long since disappeared so just regular perl input methods are used now.
This removes one of the most irritating features about ZoneMinder installs.</p>

</span></span>Added stats view &#8211; If you have the RECORD_EVENT_STATS
directive set and are viewing a still image from an event you can now view the
statistics recorded for that frame. This tells you why that frame triggered or
participated in an alarm. This can be useful in tuning the various motion
detection parameters and seeing why events occurred.</p>

</span></span>New video palette support &#8211; As well as the existing
greyscale and 24 bit RGB palettes, you can now choose YUV420P and RGB565.
Rewrote the palette/colours area a bit to enable support for other palettes in
the future if requested. Bear in mind though that YUV palettes are converted
into RGB internally so if you have the choice RGB24 may be faster as it's the
'native' format used within. </p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Added preclusive zones &#8211; Added a new zone type, the
preclusive zone. For full details see the relevant section above but in brief this
is a zone type that if alarmed will actually prevent an alarm. This completes
the pantheon of zone types I think.</p>

</span></span>Allow image and mpegs to be attached to emails &#8211; Added new
tokens (%EI1%, %EIM% and %EV%) to the filter emails. This allows the first
alarm image, most highly scored alarm image and an alarm MPEG to be attached to
alarm notification emails. Use %EV% especially with care!</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Modified scoring &#8211; Alarm scoring has been modified to give
more granularity for smaller events. This will have the effect of raising the
scores for small events while large ones will still be about the same.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

</span></span>Fixed /cgi-bin path problem &#8211; Previously you could specify
the real path to you cgi-bin directory if you have one but not the web path.
You can now do both.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

</span></span>Improved video handling in browser &#8211; The MPEG/video area of
the web GUI had been a bit neglected and looked somewhat ugly. This has now
been improved to a degree and looks a bit nicer.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Added ffmpeg support &#8211; Historically ZoneMinder has only
supported the Berkeley mpeg encoder which was slow and rather limited.
ZoneMinder now supports the ffmpeg encoder as well which is much much faster
and makes generation of MPEG videos at realistic frame rates more of a reality.
As ffmpeg has so many options and everyone will probably want a different
emphasis you can now also specify additional ffmpeg options via zmconfig.pl.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Colourise greyscale image files &#8211; In past versions,
captured greyscale images were stored as JPEG files with a corresponding
greyscale colourspace. This saved a small amount of space but meant that
mpeg_encode had to do a conversion to encode them, and ffmpeg just fell in a
heap. Now you can optionally opt to have greyscale images saved as full 24 bit
colourspace images (they still look the same) at the price of a small penalty
in CPU and disk but allowing you to easily and quickly create MPEG files. This
option is one by default but can be switched off if you do not require any MPEG
encoding.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Fast RGB diffs &#8211; Previously ZoneMinder used quite a loose
method for calculating the differences between two colour images. This was
basically averaging the differences between each of the RGB components to get
an overall difference. This is still the default but by setting
ZM_FAST_RGB_DIFFS to 'no' you can now make it calculate the Y (or brightness
value) of the pixels and use the difference between those instead. This will be
more accurate and responsive to changes but is may be slower especially on old
machines. There is a slight double whammy here if you have a YUV palette for
capture and set this option off as the image will be converted to RGB and then
partially converted back to get the Y value. This is currently very inefficient
and needs to be optimised.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Fixed STRICT_VIDEO_CONFIG &#8211; Previously this actually
behaved the opposite of what it was supposed to, ie. if you wanted it strict it
wasn't and vice versa. Thanks to Dan Merillat for pointing this one out.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Source file restructuring - The source files have been broken up
and renamed extensively to support the first stage of the code being
straightened out. Likewise the class structure has been rationalised somewhat.
The php file names have also changed in some cases so it might be best to
delete all your php and css files from the zone minder install directory first
as the old ones won't be overwritten and will be left behind.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>New &#8216;montage&#8217; view - Added a montage view showing all
your cameras simultaneously either streaming or stills. The width of this
window (in terms of number of monitors) is a configuration option.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Network camera support - A major change in this version is
support for remote or network cameras. This is currently implemented as series
of http grabs of stills rather than being able to break up motion jpeg streams.
However frame rates of from 2-10 should be achievable depending on your network
proximity to the cameras.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>zmu suspend alarm option - Added new -n option to zmu to
effectively suspend alarm detection for a monitor. This is intended for short
term use and to support PTZ cameras where alarm detection is desired to be
suspended while the camera changes orientation or zoom level.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>FPS limiting - Added a new option to monitors to add a maximum
capture rate. This allows you to limit the amount of hits a network camera gets
or to reduce the system load with many cameras. It also works with multi-port
cards and limiting the capture rate on one camera allows the spare FPS to be
allocated to other devices. For instance with two cameras and no throttle, I
get about 4FPS each. Throttling one to 2FPS allows the other to operate at 6FPS
so you can allocate your capture resources accordingly. This limiting can be
disabled while alarms are occurring as a global option in zmconfig.pl.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

</span></span>Streamed image headers - Made all headers in streamed images have
full CRLF termination which will hopefully now prevent the problems with broken
streams that had existed mostly with Mozilla (and hopefully won't break
anything else).</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span

</span></span>zmfilter execution &#8211; Previously zmfilter execution was not
synchronised with the monitor state or the analysis daemon leading to it
sometimes being run unnecessarily. From now on the zmfilter process will only
run when a monitor is active and so actually potentially generating alarms.</p>

zmu. When combined with -d it gives the config of the device and when used with
-m it dumps the current settings for the monitor and zones. Mostly useful for
bug reporting. The previous version of zmu used with just -d gave this

</span></span>Frame and event lengths fractional - A new field has been added
to the Frames table. This is 'Delta' and is a fractional number of seconds
relative to the event start time. This is intended to support the real-time
playback of events rather than just 'as fast as possible' or with a configured
delay as at present. The event length is now also fractional.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Changed colour depth to bits - Having colour depths expressed in
bytes has caused no end of problems. This is now changed to be bits and can be
changed via a dropdown to limit what can be entered. Don't forget to run the
zmalter script to update your DB.</p>

style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Fixed config problems in zmcfg.h - Some config was not being set
up correctly in zmcfg.h.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Zmwatch now works on image delay and not fps - Previously the
zmwatch daemon detected capture daemon failure by trying to use the FPS
setting. This was imprecise and prone to false readings. It now uses the time
delay since the last captured image.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Added zmpkg.pl and zm scripts - There are now two new scripts.
zmpkg.pl is in charge of starting and stopping ZoneMinder as a whole package
and zm is designed to be (optionally) installed into your init.d directory to
use ZoneMinder as a service.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Fixed bug in Scan mode - The monitor cycle or scan mode had stopped
working properly due to images not being generated. This is now fixed.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Revamped the console window slightly - The console window has now
been reformatted slightly to give more and better information including server
load.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Added email and messaging to filters - Filters now allow you to
send emails or messages (basically just short emails intended for mobile
devices) on alarms. The format and possible content for these emails is in
zmconfig_eml.txt and zmconfig_msg.txt.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Made zmdc more aggresive in killing old processes - The zmdc.pl
daeamon will now kill any ZoneMinder processes it finds on startup or shutdown
to prevent orphans from being left around.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Configuration changes - Previously there were a lot of files
generated by configure. Now only zmconfig.pl is generated this way and all the
other configuration files are created by zmconfig.pl (from .z files) to
centralise configuration more.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Fixed cambolzola opt bug - There was a bug in the Cambozola
options, I can't remember what it was but it's fixed!</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Retaint arguments in zmdc.pl - In some installations zmdc was
complaining about tainted arguments from the socket. These are now detainted
prior to sending and after receiving.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Forced alarms - You can now force alarms when looking at the
monitor window should anything catch your attention. You have to remember to
switch them off as well though.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Looser video configuration - Some video configuration errors can
now be ignored via the STRICT_VIDEO_CONFIG option.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Monitor window refresh on alarm - When the monitor window is
active and an alarm has occurred the most recent alarms list is immediately
refreshed to show it.</p>

<h1><a name="_Toc125113533"><span style='text-decoration:none'>13.<span
style='font:7.0pt "Times New Roman"'>&nbsp; </span></span><u>To Do</u></a></h1>
<p class=MsoPlainText>Seeing as ZoneMinder is so young and has kind of evolved
rather than being planned there are a bunch of improvements and enhancements
still to do, here is just a sample.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Perhaps split out devices - I think devices should probably be a
separate table and class from monitors. Not critical but would represent a
better model.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Comments - Needs many more, but that's just me I'm hopeless at
commenting things out. I'll get round to it soon though honest! You're lucky to
even get this document.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Optimised zones - The zones could do with being sorted out a bit
to optimise the processing of overlapping ones, at the moment you can waste
resource unless your zones are kept very tidy.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Create zones using server side image maps - This would make it
easier to precisely define and see where your zone is going to go. Not critical
but handy but a bugger to do.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Zone Definitions - Allow zones to be defined according to a
colour coded bitmap or as polygons. Currently all zones are rectangular this
would add a bit of flexibility. Would need a bit of a rewrite though. This will
incur a slight penalty on startup and a very slight one on processing for all
reasonably shaped zones. Work has already begun on this feature.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Mouseover help - A bit more help popping up when you mouseover
things would be handy. A bit more help full stop actually.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Automatic device configuration - Video 4 Linux supports various
device queries, it should be possible to get most of the device capability
information from the device itself. The zmu utility does this now but it's not
yet integrated into the web pages.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Extend the API. Well ok it's not really got an API yet but the
image data is held in shared memory in a very simple format. In theory you
could use the capture daemon to gab the images and other things could read them
from memory or the analysis daemon could read images from elsewhere. Either way
this should be done through an API, and would need a library I think. Also the
zmu utility could probably do a whole lot more to enable other things to manage
when the daemons become active etc.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Allow ZoneMinder to 'train' itself by allowing the user to select
events that are considered important and to discard those that should be
ignored. ZoneMinder will interpolate, add a bit of magic, and recommend
settings that will support this selection automatically thereafter. The hooks
for this are already in to some extent.</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>Add sound support to allow a captured audio channel to be
associated with a video device. Work on this feature has already begun.</p>

<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>When opening a link to an event etc from a notification email the
window that is opened is just a regular browser window and not in the context
of a proper ZoneMinder web interface. Thus it comes up too big usually (not a
major issue) and also things like 'Delete' don't work as it wants to do things
to its parent (which is more of a major issue).</p>
<p class=BullettedChar><span style='font-family:"Courier New"'>o<span
style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span>The .sock files used by the *nix sockets I suspect may have the
odd permission issue now and again. I think everything recovers from it but it
needs checking out.</p>
<p class=MsoPlainText>Probably bucket loads more, just fire them at me.</p>

</span></span>Yes, those are tabs in the indents; I like tabs so don't go
changing them to spaces please. Also, yes I<> like my opening braces on their
own line most of the time, what's the point of brackets that don't line up?</p>
<p class=MsoPlainText>Everything else that isn't definitely broken is probably
deliberate, or was once anyway.</p>
