</span></span><![endif]><u><span lang=EN-GB>Introduction<o:p></o:p></span></u></h1>
<p class=MsoPlainText><span lang=EN-GB>Welcome to ZoneMinder, the new
all-in-one Linux GPL'd security camera solution. A few months back my garage
was burgled and all my wine and power tools were nicked! 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 a baby but hopefully it can grow up to be something that can be genuinely
useful and maybe one day either prevent similar incidents or perhaps bring some
perpetrators to justice.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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 please let me know.</span></p>
<p class=MsoPlainText><span lang=EN-GB>ZoneMinder is free but if you do get a
ZoneMinder up and running and find it useful then please feel free to visit <a
href="http://www.zoneminder.com/donate.html">http://www.zoneminder.com/donate.html</a>
where any donations will be appreciated and will help to fund future
improvements of ZoneMinder.</span></p>
<h1><![if !supportLists]><span lang=EN-GB style='text-decoration:none;
text-underline:none'>2.<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span><![endif]><u><span lang=EN-GB>Requirements<o:p></o:p></span></u></h1>
<p class=MsoPlainText><span lang=EN-GB>ZoneMinder needs a couple of things to
work.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Next it does things with JPEGs so you'll
need at least libjpeg.a which I think come as standard nowadays with most
distributions. It also uses the netpbm utilities in a very limited way to
generate thumbnails under certain circumstances though this can be modified.</span></p>
<p class=MsoPlainText><span lang=EN-GB>ZoneMinder can generate MPEG videos if
necessary, for this you'll need either ffmpeg (recommended) or the Berkeley MPEG
encoder. If you don't have either don't worry, as the options will be hidden
and you'll not miss much really. 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Finally, there is quite a bit of image
streaming in the package. So if you don't have Netscape or another browser that
supports image streaming natively I recommend you get the excellent Cambozola
java applet from <span class=MsoHyperlink><span style='color:blue'>http://www.charliemouse.com/code/cambozola/</span></span>
which will let you view the image stream in Internet Explorer and others.
Otherwise you're limited to just refreshing still images.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Hardware-wise, ZoneMinder has been used
with various video and USB cameras with the V4L interface. I don't have a lot
of cameras myself so I've not had change to test it with a huge ranger 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 is not listed. You do need to have
Video 4 Linux installed. I've not got too many machines so I've only really
used it on RedHat, which does 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.</span></p>

text-underline:none'>3.<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</span></span><![endif]><u><span lang=EN-GB>Building<o:p></o:p></span></u></h1>
<p class=MsoPlainText><span lang=EN-GB>The first thing you need to do is run
the included configure script to define some initial configuration, just type</span></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>./configure
--with-mysql=&lt;your MySQL root&gt; --with-webdir=&lt;your web directory&gt;
--with-cgidir=&lt;your cgi directory&gt;<o:p></o:p></span></i></p>
<p class=MsoPlainText><span lang=EN-GB>where --with-mysql identifies where you
have installed MySQL (usually /usr), --with-webdir is the directory to which
you want to install the PHP files, and --with-cgidir is the directory to which
you want to install CGI files. These directories could be /var/www/html/zm and
/var/www/cgi-bin for example. There are also two further arguments you can add
if your web user and group are not both 'apache'. These are --with-webuser and
--with-webgroup. Type</span></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>./configure
<EFBFBD>help<o:p></o:p></span></i></p>
<p class=MsoPlainText><span lang=EN-GB>for details.</span></p>
<p class=MsoPlainText><span lang=EN-GB>That's the build configuration sorted
out. The next thing you have to do is do a little more runtime specific
configuration. ZoneMinder config is scattered around various files in the
distribution so to make things easier for you there is a ZoneMinder
configuration utility included. Type</span></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>perl
./zmconfig.pl<o:p></o:p></span></i></p>
<p class=MsoPlainText><span lang=EN-GB>to get it started. It is an interactive
utility and will prompt you by asking you various questions. For most questions
typing '?' will give you additional help if you need it. Once you've answered
all the questions it will write out a configuration file called 'zmconfig.txt'
and then process various files to substitute the information in them. If you
run it again it will remember your answers from before by reading
'zmconfig.txt' before it starts. You can also edit this file directly to change
values. If you do you can run zmconfig.pl in non-interactive mode by typing</span></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>perl
./zmconfig.pl -noi<o:p></o:p></span></i></p>
<p class=MsoPlainText><span lang=EN-GB>which will just read your file and do
the substations with no questions asked. Also if you are upgrading from version
0.9.7 (or later) you can copy your old zmconfig.txt file into the current build
directory before you run zmconfig.pl and it will use your preferences as a
basis for generating the new ones. There are two classes of options, <20>core<72>
options which much be specified with zmconfig which detail things such as
database passwords which are compiled into ZoneMinder and other options with
are stored in the database and which can be modified dynamically via the
<EFBFBD>options<EFBFBD> section of the web interface. Only the first set need to be completed
with zmconfig at this stage.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Among the first questions zmconfig.pl
asks you are to do with the database and the next thing you should do is create
it and the associated database users. You may notice that there are two sets of
users and passwords. This is because the streaming server and utility binaries
require only read access to the database so you may wish to create both a full
access user and a limited access user. You can of course set both to the full
access user. The included schema (zmschema.sql) can be used to actually create
the tables required. The database is usually called just 'zm'.</span></p>
<p class=MsoPlainText><span lang=EN-GB>If you are upgrading from a previous
version you can use zmalter-x.y.z.sql to upgrade your database and make the
necessary changes where x.y.z identifies the version of ZoneMinder you had
installed previously. So if you are going from version 0.9.7 to version 0.9.11
you would run the scripts for all intervening versions to get to the current
one, i.e. zmalter-0.9.7.sql, zmalter-0.9.8.sql, zmalter-0.9.9.sql and
zmalter0.9.10.sql. For a new installation the simplest way to create your
database and users is as follows,</span></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>mysql
mysql &lt; zmschema.sql<o:p></o:p></span></i></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>mysql
mysql<o:p></o:p></span></i></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>grant
select,insert,update,delete on &lt;your database name&gt;.* to '&lt;your first
username&gt;'@localhost identified by '&lt;your first password&gt;';<o:p></o:p></span></i></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>grant
select on &lt;your database name&gt;.* to '&lt;your second
username&gt;'@localhost identified by '&lt;your second password&gt;'<o:p></o:p></span></i></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>quit<o:p></o:p></span></i></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>mysqladmin
reload<o:p></o:p></span></i></p>
<p class=MsoPlainText><span lang=EN-GB>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 use the
hostname of the remote machine instead of localhost.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Then just type <i style='mso-bidi-font-style:
normal'>'make'</i> and off you go.</span></p>
<h1><![if !supportLists]><span lang=EN-GB style='text-decoration:none;

</span></span><![endif]><u><span lang=EN-GB>Installation<o:p></o:p></span></u></h1>
<p class=MsoPlainText><span lang=EN-GB>Once the build has completed you should
have several shiny new binaries. I will now briefly describe what each of them
does.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmc</span></b><span lang=EN-GB> - This is the
ZoneMinder Capture daemon. This binary's job is to sit on a video device and such
frames off it as fast as possible, this should run<span style="mso-spacerun:
yes"><EFBFBD> </span>at more or less constant speed.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zma</span></b><span lang=EN-GB> - This is the
ZoneMinder Analysis daemon. This is the component that goes through the
captured frames and checks them for alarming events. It generally keeps up with
the zmc but if very busy may skip some frames to prevent it falling behind.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmf</span></b><span lang=EN-GB> - 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 to do more analysis (!) and so keep
up with the capture daemon better. If it isn<73>t running or dies then the
Analysis daemon just writes them itself.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zms</span></b><span lang=EN-GB> - This is the
ZoneMinder Streaming server. The web interface connects with this to get
real-time or historical streamed images.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmu</span></b><span lang=EN-GB> - This is the
ZoneMinder Utility. It's basically a handy command line interface to several
useful functions. It<49>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.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmfix</span></b><span lang=EN-GB> - 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>As well as this there are the web PHP
files in the web directory and some perl scripts in the scripts directory, only
one of which may actually be used in a minimal installation. These scripts all
have some configuration at the top of the files which should be viewed and
amended if necessary and are as follows.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmpkg.pl</span></b><span lang=EN-GB> - 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.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmdc.pl</span></b><span lang=EN-GB> - 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.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmfilter.pl</span></b><span lang=EN-GB> - 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.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmaudit.pl</span></b><span lang=EN-GB> - 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.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmx10.pl</span></b><span lang=EN-GB> - 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<6F>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.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zmwatch.pl</span></b><span lang=EN-GB> - 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.</span></p>
<p class=MsoPlainText style='margin-left:18.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>zm</span></b><span lang=EN-GB> - This is the
(optional) ZoneMinder init script, see below for details.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Finally, check zm_config.php in the web
directory and amend any configuration necessary in there. Most will have
already been done by the configuration utilities.</span></p>
<p class=MsoPlainText><span lang=EN-GB>At this stage typing 'make install' will
install everything to the desired locations, you may wish to su to root first
though. The installation routine will copy the binaries and scripts to your
chosen install location, usually /usr/local/bin and then move zms to your
cgi-bin area. It will then copy the web files to your chosen directory and
ensure they have the right permissions. Finally it tries to link zm.php to
index.php but will not overwrite an existing file if it exists.</span></p>
<p class=MsoPlainText><span lang=EN-GB>The 'zm' script does not get installed
automatically as it is not necessary for the operation of the ZoneMinder setup
per se. However if you want to ensure that the ZoneMinder daemons are started
on reboot etc copy it to your init.d directory, usually something like /etc/rc.d/init.d
and then add it by doing</span></p>
<p class=MsoPlainText><i style='mso-bidi-font-style:normal'><span lang=EN-GB>/sbin/chkconfig
--add zm<o:p></o:p></span></i></p>
<p class=MsoPlainText><span lang=EN-GB>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 style='mso-bidi-font-style:normal'>'service
zm start'</i> or <i style='mso-bidi-font-style:normal'>'service zm stop'</i> etc.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Now start your web browser and point it
at your zm.php and off you go.</span></p>

</span></span><![endif]><u><span lang=EN-GB>Tutorial<o:p></o:p></span></u></h1>
<p class=MsoPlainText><span lang=EN-GB>What you see now (and subsequently)
depends on whether you chose to run ZoneMinder in authenticated mode or not.
This is an option that lets you specify whether anyone that goes to the
ZoneMinder web pages must authenticate themself in order to be given
permissions to perform certain tasks. If you chose this mode then you will need
to log in here. By default a fully privileged user <20>admin<69> has been created
with a password also of <20>admin<69>. You should change this password as soon as
possible.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Once you<6F>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 a <20>start<72> or <20>stop<6F> link
depending on the current state. 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Please bear in mind that from here on

</span></span><![endif]><span lang=EN-GB>Defining Monitors</span></h2>
<p class=MsoPlainText><span lang=EN-GB>To use ZoneMinder properly you need to
define at least one Monitor. Essentially, a monitor is associated with a camera
and will 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>To help you get started on the video
configuration the best thing is to us a tool like 'xawtv' to get a picture
you're happy with, and to check your camera works. Then run 'zmu -d
&lt;device_no&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_no' referred to here is
a number corresponding to the digit at the end of your device file, so
/dev/video0 has a 'device_no' of 0 etc. If 'zmu' gives you an error related to
permissions run 'zmfix -a' to make sure you can access all the video devices.</span></p>
<p class=MsoPlainText><span lang=EN-GB>The options explained in a little more
detail are as follows,</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Name</span></b><span lang=EN-GB> - First choose a name
for it, anything you like. </span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Function</span></b><span lang=EN-GB> - This
essentially defines what the monitor is doing. This can be 'None' meaning the
monitor is currently disabled, 'Passive' meaning you can watch the streams
coming from the camera but no alarms or events will be generated, or 'Active'
meaning all the images will be analysed as well as the stream being available
to watch. If you have specified X10 support then X10 is also available as an
option, which means that the monitor is generally passive but may switch to or
from active mode on receipt of X10 commands (see below). Generally you'll want
'Active' but for now leave this at 'None'. </span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Source Type</span></b><span lang=EN-GB> <20> This
determines whether the camera is a local one attached to a physical video or
USB port on your machine or a remote network camera or similar. Choosing one or
the other affects which set of three options are shown next.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Device Number/Channel</span></b><span lang=EN-GB> <20>
For a local camera enter the device number that your camera is attached to. If
it is /dev/video0 enter '0' etc. Some video devices, e.g. BTTV cards support
multiple cameras so in the Channel box choose the appropriate channel, or leave
it at zero if you're using a USB camera or one without channels. </span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Device Format</span></b><span lang=EN-GB> <20> For a
local camera 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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Remote Host/Port/Path</span></b><span lang=EN-GB> <20>
For remote cameras use these fields to enter the full URL of the camera.
Basically if your camera is at <span class=MsoHyperlink><span style='color:
blue'>http://camserver.home.net:8192/cameras/camera1.jpg</span></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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Orientation</span></b><span lang=EN-GB> <20> 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 not set the orientation here. 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 <20>Rotate Right<68> here then set the height to be 352 and width to be 288.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Capture Width/Height</span></b><span lang=EN-GB> - 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
352x288 and then perhaps increasing and seeing how performance is affected.
This size should be adequate in most cases.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Capture Palette</span></b><span lang=EN-GB> - 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 scale first, and then 24 bit colour. If neither of these work very
well then YUV420P probably will.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Timestamp Label Format</span></b><span lang=EN-GB> -
This relates to the timestamp that is applied to each frame. It is a sprintf
style string. It is actually passed through sprintf and then through printf to
add the monitor name so a format of '%%s - %y/%m/%d %H:%M:%S' would be
recommended though you can modify it if necessary. If you don<6F>t want a
timestamp or have a camera that puts one on itself then leave this field blank.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Timestamp Label X/Y</span></b><span lang=EN-GB> - 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. A Y value of the height you supplied earlier minus
8 will place it on the bottom of the image.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Image Buffer Size</span></b><span lang=EN-GB> - 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 <20>n<EFBFBD> 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 100
is usually ok.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Warm-up Frames </span></b><span lang=EN-GB>- 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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Pre/Post Event Image Buffer</span></b><span
lang=EN-GB> - 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. Both of these values added together should not exceed the ring buffer
size. You should also bear in mind the frame rate of the camera when choosing
this value. 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 well
capture at 25FPS and you will want to ensure that this setting enables you to
view a reasonable time frame pre and post event.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Maximum FPS</span></b><span lang=EN-GB> <20> 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 is difficult to
synchronise two different capture rates precisely. There is a global
configuration option that allows you to turn this limiting off in the event of
an alarm.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>FPS Report Interval</span></b><span lang=EN-GB> - 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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Reference Image Blend %ge</span></b><span lang=EN-GB>
- 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 recommended value of 10 here, each
images 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 later if necessary.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>X10 Activation String</span></b><span lang=EN-GB> -
This option is only available if you have specified X10 support in the
configuration. If you have then this contents of this field determine when a
monitor starts and stops being Active if its function is set to X10. Basically
what this means is that a monitor with a Function of X10 normally acts as it is
Passive, i.e. you can watch the video stream but no analysis is done. On
receipt of the appropriate X10 signal however it effectively changes to Active
mode and starts to analyse images until an X10 signal (or elapsed time) changes
it back to Passive again. The format of this string is as follows,</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>n</span></u><span
lang=EN-GB> : 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.</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>!n</span></u><span
lang=EN-GB> : 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.</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>n+</span></u><span
lang=EN-GB> : 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.</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>n+&lt;seconds&gt;</span></u><span
lang=EN-GB> : As per the previous mode except that the monitor will deactivate
itself after the given number of seconds.</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>n-</span></u><span
lang=EN-GB> : 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.</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>n-&lt;seconds&gt;</span></u><span
lang=EN-GB> : As per the previous mode except that the monitor will activate
itself after the given number of seconds.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>X10 Input Alarm String</span></b><span lang=EN-GB> -
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 apply except that for
activated read alarmed and for deactivated read unalarmed(!). Again leave this
blank for now.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>X10 Output Alarm String</span></b><span lang=EN-GB> -
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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Finally, click 'Save' to add your
monitor.</span></p>
<p class=MsoPlainText><span lang=EN-GB>On the main console listing you will now
see your monitor and some of its vital statistics. Each column is also a link
and you get to other functions of ZoneMinder by choosing the appropriate one.
Describing them left to right, they are as follows.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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. This is described more fully below.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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. 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 <20>Passive<76> or 'Active', which will ensure that one or more
appropriate daemons are started automatically.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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 which allows you to cycle
through a shot from each of your monitors (unless they are switched off) and
get a streamed or still image from each in turn. There may also be a link
titled <20>Montage<67> which allows you view all your enabled cameras 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. </span></p>

text-underline:none'>5.2.<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;
</span></span><![endif]><span lang=EN-GB>Defining Zones</span></h2>
<p class=MsoPlainText><span lang=EN-GB>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
created 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 and will be red. Beneath that 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. The options are as follows.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Name</span></b><span lang=EN-GB> <20> 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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Type</span></b><span lang=EN-GB> - This is one of the
more important concepts in ZoneMinder and there are five to choose from.</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>Active</span></u><span
lang=EN-GB> : 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. </span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>Inclusive</span></u><span
lang=EN-GB> : 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.</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>Exclusive</span></u><span
lang=EN-GB> : 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.</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>Preclusive</span></u><span
lang=EN-GB> : 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.</span></p>
<p class=MsoPlainText style='margin-left:36.0pt'><u><span lang=EN-GB>Inactive </span></u><span
lang=EN-GB>: 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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><span lang=EN-GB>I 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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Units</span></b><span lang=EN-GB> - This setting which
details whether certain of the following settings are in Pixels or Percent of
the frame. In general pixels is more precise whereas percentages are easier to
use to start with. 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 and refine any gaps. Repeated
flipping between the settings will cause rounding errors, as ZoneMinder in
general is not at home to Mr Floating Point for reasons of performance. </span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Min/Maximum X/Y</span></b><span lang=EN-GB> -
Following the units the next four settings define the bounds of the Zone in the
monitor frame and are self-explanatory with the exception of the fact that the
minima are at the top left of the frame and the maxima are at the bottom right
rather than in a Cartesian style.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Alarm Colour </span></b><span lang=EN-GB>- 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

normal'><span lang=EN-GB>Alarm Threshold</span></b><span lang=EN-GB> - This
represents 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 does 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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Min/Maximum Alarmed Area</span></b><span lang=EN-GB> -
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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Filter Width/Height</span></b><span lang=EN-GB> <20> 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 pixels and should be fairly small, and an odd number.
Application of this filter removes any tiny or discontinuous pixels that don't
form part of a discrete block. </span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Min/Maximum Filtered Area</span></b><span lang=EN-GB>
<EFBFBD> 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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Min/Maximum Blob Area</span></b><span lang=EN-GB> -
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.</span></p>
<p class=MsoPlainText style='margin-left:27.0pt'><b style='mso-bidi-font-weight:
normal'><span lang=EN-GB>Min/Maximum Blobs </span></b><span lang=EN-GB>-
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 becomes an alarm event.</span></p>

</span></span><![endif]><span lang=EN-GB>Viewing Monitors</span></h2>
<p class=MsoPlainText><span lang=EN-GB>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. On doing so up will
pop another window which should be scaled to contain a heading, an image from
your monitor, a status and a list of events if any have been generated.
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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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 cooling down, 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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 configuration 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 frequently refreshing may impact on performance.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Below the status is a list of recent
events that have occurred, by default this<span style="mso-spacerun: yes"><EFBFBD>
</span>is a listing of just the last 10 but clicking on 'All' will give you a
full list<span style="mso-spacerun: yes"><EFBFBD> </span>and 'Archive' will take you
to the event archive for this monitor, more on this<span style="mso-spacerun:
yes"><EFBFBD> </span>later. Clicking on any of the column headings will sort the
events appropriately.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>

text-underline:none'>5.4.<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;
</span></span><![endif]><span lang=EN-GB>Filtering Events</span></h2>
<p class=MsoPlainText><span lang=EN-GB>The other columns on the main console
window contain various event totals for your monitor 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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. All
of the preceding elements take a very flexible free format of dates and time
based on the PHP strtotime function
(http://www.zend.com/manual/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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>The other elements 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. Once your filter is specified, clicking
'submit' will filter the events according to your specification. If you have
created a filter you want to keep, you can name it and save it by clicking
'Save'.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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. In most cases
you can specify your preferences for upload formats and email content during
configuration time (make sure you type '?' to get help on options). Emails and
messages (essentially small emails intended for mobile phones or pagers) have 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. See the included
templates zmconfig_eml.txt and zmconfig_msg.txt for a fuller explanation of the
availability and meaning of these tokens.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<h2><![if !supportLists]><span lang=EN-GB style='text-decoration:none;
text-underline:none'>5.5.<span style='font:7.0pt "Times New Roman"'>&nbsp;&nbsp;&nbsp;
</span></span><![endif]><span lang=EN-GB>Viewing Events</span></h2>
<p class=MsoPlainText><span lang=EN-GB>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.
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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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).</span></p>
<p class=MsoPlainText><span lang=EN-GB>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>The final option of generating an MPEG
video is still somewhat experimental and it's usefulness may vary. It can use
either the Berkeley MPEG encoder or the faster and new ffmpeg encoder. Either
of these will generate a short video, which will be downloaded to your browsing
machine to view. Due to the relatively slow frame rate that ZoneMinder will
capture at and the high minimum frame rate that the Berkeley encoder uses
videos created by this method will be very quick. However when using the ffmpeg
encoder, ZoneMinder will attempt to match the duration of the video with the
duration of the event. This has the useful effect of making the video watchable
and not too quick while having the unfortunate side effect of increasing file
size and generation time. Ffmpeg in particular 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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. I will be the first
to admit that this area of the package is not particularly well implemented and
needs work, and probably a better encoder. 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.</span></p>

</span></span><![endif]><span lang=EN-GB>Options and Users</span></h2>
<p class=MsoPlainText><span lang=EN-GB>The final area covered by the tutorial
is the options and user section. If you are running in authenticated mode and
don<EFBFBD>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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>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 <20>?<3F> 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>If you have changed the value of an
option you should then <20>save<76> 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>As mentioned above, you may also see a
<EFBFBD>users<EFBFBD> tab. 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.</span></p>
<p class=MsoPlainText><span lang=EN-GB>There are also four values that define
the user permissions, these are <20>stream<61>, <20>events<74>, <20>monitors<72> and <20>system<65>
Each can have values of <20>none<6E>, <20>view<65> or <20>edit<69> apart from <20>stream<61> which has
no <20>edit<69> setting. These values cover access to the following areas; <20>stream<61>
defines whether a user is allowed to view the <20>live<76> 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 <20>none<6E>. The <20>events<74> setting determines whether a
user can view and modify or delete any retained historical events. The
<EFBFBD>monitors<EFBFBD> setting specifies whether a user can see the current monitor
settings and change them. Finally the <20>system<65> 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. As well as these
settings there is also a monitor ids setting that can be used for non-<2D>system<65>
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 <20>monitors<72> 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 <20>system<65> privileges then the monitors ids setting
is ignored and has no effect.</span></p>
<p class=MsoPlainText><span lang=EN-GB>That<EFBFBD>s pretty much is it for the tour.
You should experiment with the various setting to get the results you think are
right for your. Naturally, letting thousands of events build up is not good for
the database or your file system so you should endeavour to either prevent
spurious events from being generated in the first place or ensure that you
housekeep them strictly.</span></p>
<p class=MsoPlainText><span lang=EN-GB>Have fun, please report any bugs or
features you'd like to see and hopefully ZoneMinder can be your camera

don't work then feel free to get in touch and I'll see if I can suggest

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_no&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 and recompile and

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

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

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=MsoHyperlink><span style='color:blue'>http://www.php.<a
name="_Hlt42867874">n</a>et/manual/en/configuration.directives.php#ini.short-open-tag</span></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 wil 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.</span></p>

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.</span></p>

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<EFBFBD>s associated httpd process, continue to grow in memory size until they kill
the system. This appears to be a bug in either the compiler or apache on RH9.
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.</span></p>

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.</span></p>

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.</span></p>

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.</span></p>

accordingly. This limiting can be disabled while alarms are occurring as a

with being sorted out a bit to optimise the processing of overlapping ones, at

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
