\par A }{\insrsid150409 while}{\insrsid150409 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 leas
t 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 perpe
trators to justice.
\par 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 cam
era 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.
\par 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 c
omes 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 allow
s
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 ca
n even be installed as a system service ensuring it is right there if your computer has to reboot for any reason.
\par 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 reg
ions that you don't wish to track or define areas that will alarm if various thresholds are exceeded in conjunction with other zones.
\par 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.
\par ZoneMinder is free but if you do get ZoneMinder up and running and find it useful then please feel free to visit }{\field{\*\fldinst {\insrsid150409 HYPERLINK http://www.zoneminder.com/donate.html }{\insrsid354063 {\*\datafield
\insrsid150409 where any donations will be appreciated and will help to fund future improvements of ZoneMinder. This would be especially appreciated if you use ZoneMinder as part of your business or to protect your property.
\par }\pard\plain \s15\qj \li0\ri0\sa180\widctlpar\nooverflow\faroman\rin0\lin0\itap0 \f1\fs20\lang2057\langfe1033\cgrid\langnp2057\langfenp1033 {\insrsid150409 ZoneMinder needs a couple of things to work.
\par 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
\rquote s probably worth installing all the pure mysql rpm files to be sure you have the right ones.
\par Next it does things with JPEGs so you'll need at least libjpeg.a which I think come as standard nowadays with most distr
ibutions. It also uses the netpbm utilities in a very limited way to generate thumbnails under certain circumstances though this can be modified.
\par ZoneMinder can generate MPEG videos if necessary, for this you'll need either ffmpeg (recommended) or the Berk
eley 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 much. The web interface uses PHP and so you need that in your apache or other web server as well, make sure MySQL support is a
vailable 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.
\par 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 }{\cs16\ul\cf2\insrsid150409
http://www.charliemouse.com/code/cambozola/}{\insrsid150409 which will let you view the image stream in Internet Explorer and others. Otherwise you're limited to just refreshing still images.
\par 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 wi
th 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 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.

The first thing you need to do is run the included configure script to define some initial configuration, just type
\par }{\i\insrsid150409 ./configure --with-mysql=<your MySQL root> --with-webdir=<your web directory> --with-cgidir=<your cgi directory>
\par }{\insrsid150409 where }{\i\insrsid150409 --with-mysql}{\insrsid150409 identifies the root directory where you have installed MySQL (usually /usr), }{\i\insrsid150409 --with-webdir}{\insrsid150409
is the directory to which you want to install the PHP files, and }{\i\insrsid150409 --with-cgidir}{\insrsid150409 is the directory to which you want to install CGI files. These directories could be }{\i\insrsid150409 /var/www/html/zm}{\insrsid150409
and }{\i\insrsid150409 /var/www/cgi-bin}{\insrsid150409 for example. }{\insrsid150409 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\insrsid150409 \endash with-ffmpeg=<
path to ffmpeg build directory>}{\insrsid150409 to help configure find it. Note this path should be to the directory you build ffmpeg in and not where it is installed. This package installs only binaries whereas ZoneMinder needs access to the header a
nd libraries files which remain. If you have built ffmpeg with the mp3lame feature turned on your will additionally need to tell configure where to find that, to prevent unresolved dependencies. To do this add the }{\i\insrsid150409 \endash
with-lame=<path to lame directory>}{\insrsid150409 option as well. }{\insrsid150409 There are also two further arguments you can add if your web user and group are not both 'apache'. These are }{\i\insrsid150409 --with-webuser}{\insrsid150409 and }{
\i\insrsid150409 --with-webgroup}{\insrsid150409 . Type
\par }{\i\insrsid150409 ./configure \endash help
\par }{\insrsid150409 for details}{\insrsid150409 on these options}{\insrsid150409 .
\par That's the build configuration sorted out. The ne
xt thing you have to do is do a little more runtime specific configuration. ZoneMinder configuration is scattered around various files in the distribution so to make things easier for you there is a ZoneMinder configuration utility included. Type
\par }{\i\insrsid150409 perl ./zmconfig.pl
\par }{\insrsid150409
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 configurat
ion 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. If you just want to rerun the substitutions you can run zmconfig.pl in non-interactive mode by typ
ing
\par }{\i\insrsid150409 perl ./zmconfig.pl -noi
\par }{\insrsid150409 which will just read your file and do the substitutions with no questions asked. There are two classes of options, \lquote core\rquote
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 \lquote options\rquote
section of the web interface. Only the first set need to be completed with zmconfig at this stage. If you want to change just a few options and can\rquote
t access the options dialog via the web you can append them as parameters to zmconfig and it will just ask you about those. So for example,
\par }{\insrsid150409 however it is fairly dumb }{\insrsid150409 and }{\insrsid150409 will not tell you if you make a typo and misspell an option.
\par 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. T
his 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 (zmschem
a.sql) can be used to actually create the tables required. The database is usually called just 'zm'.
\par If you are a first time user the first run of zmconfig.pl will warn you about the missing database, you can ignore those errors this time. Once you\rquote ve run i
t for the first time the schema file should have your desired database name in it so use it to create the database (see below). Once the database and permissions are set up rerun zmconfig.pl with the \endash
noi option to get it to load the configuration into your new database.
\par 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 versi
on 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.
\par For a new installation the simplest way to create your database and users is as follows,
\par }{\i\insrsid150409 mysql mysql < zmschema.sql
\par }{\insrsid150409 You may need to supply a username and password to the mysql commands in the first place to give yourself sufficient privileges to pe
rform 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.
\par Then just type }{\i\insrsid150409 'make'}{\insrsid150409 and off you go.

build has completed you should have several shiny new binaries. I will now briefly describe what each of them does.

sit on a video device and suck frames off it as fast as possible, this should run at more or less constant speed.
\par }{\b\insrsid150409 zma}{\insrsid150409 - This is the ZoneMinder Analysis daemon. This is the component that goes through the captured frames and checks them for motion which m
ight 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.
\par }{\b\insrsid150409 zmf}{\insrsid150409 - This is the ZoneMinder Frame daemon. This is an optional daemon that can run in concert with the Analys
is 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\rquote
- 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 th
e 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).
\par }{\b\insrsid150409 zmu}{\insrsid150409 - This is the ZoneMinder Utility. It's basically a handy command line interface to several useful functions. It\rquote
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.
\par }{\b\insrsid150409 zmfix}{\insrsid150409 - This is a small binary tha
t 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 permiss
ions. This is not a daemon and runs only on system start and then exits.
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.
- 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.
\par }{\b\insrsid150409 zmdc.pl}{\insrsid150409 - This is the ZoneMind
er 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.
\par }{\b\insrsid150409 zmfilter.pl}{\insrsid150409 - This script contro
ls 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.
- 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 lin
e. 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 th
is is set then it is this script that tidies up the rest.
\par }{\b\insrsid150409 zmx10.pl}{\insrsid150409 - 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 ZoneMinde
r 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\rquote
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.
\par }{\b\insrsid150409 zmwatch.pl}{\insrsid150409 - 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 probl
ems in the video drivers to cause this so this script makes sure that nothing important gets missed.
\par }{\b\insrsid150409 zmupdate.pl}{\insrsid150409 \endash Currently this script is responsible for checking whether a new version of ZoneMinder is available and other miscellaneous actions related to
upgrades and migrations. Eventually it is intended to be a \lquote one stop shop\rquote for any upgrades and will execute everything necessary to update your installation to a new version.
\par }{\b\insrsid150409 zm}{\insrsid150409 - This is the (optional) ZoneMinder init script, see below for details.
lly, 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 but some scripts have a \lquote VERBOSE\rquote flag you can set to get more debug out.
\par At this stage typing 'ma
ke 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 ar
ea. 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 already exists.
\par The 'zm' script does not get installed automa
tically as it is not necessary for the operation of the ZoneMinder setup per se and is not necessarily supported for distributions other than RedHat 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
\par }{\i\insrsid150409 chkconfig --add zm
\par }{\insrsid150409 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\insrsid150409 'service zm start'}{\insrsid150409 or }{\i\insrsid150409
'service zm stop'}{\insrsid150409 etc. You may need to use the \lquote }{\cs26\i\insrsid150409 \emdash levels}{\insrsid150409 \rquote parameter to chkconfig to ensure that ZoneMinder is started when you need it to.

\par Once you\rquote ve logged in, or if you are run
ning 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 ser

to start with. This is a link that you can click on to control the ZoneMinder system as a whole. Below that are various other links including one detailing the

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.
\par To help you get started on the video configuration the best thing is to us a tool like 'xawtv' (}{\field\flddirty{\*\fldinst {\insrsid150409 HYPERLINK "http://bytesex.org/xawtv/" }{\insrsid354063 {\*\datafield
) to get a picture you're happy with, and to check your camera works. Then run 'zmu -d <device_no> -q -v' to get a dump of the settings (no

ber 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.

In this case continuous events of a fixed length are generated regardless of motion which is analogous to a convention time-lapse video recorder. No motion detection takes place in this mode.
This is a hybrid of Modect and Record and results in both fixed length events being recorded and also any motion being highlighted within those events.

\par }{\b\insrsid150409 Section Length}{\insrsid150409 \endash This specifies the length (in seconds) of any fixed length events produced when the monitor function is \lquote Record\rquote or \lquote Mocord\rquote
. 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.
\par }{\b\insrsid150409 Frame Skip }{\insrsid150409 \endash This setting also applies only to the \lquote Record\rquote or \lquote Mocord\rquote 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, whereas one would mean that one frame is skipped between each saved one, two means that two frames are skipped between each
saved one etc. An alternate way of thinking is that one in every \lquote Frame Skip + 1\rquote
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 fra
me rate. The alternate approach is to limit the capture frame rate which will obviously affect the rate at which frames are saved.
\par }{\b\insrsid150409 Run Mode }{\insrsid150409 \endash Two choices are available here. \lquote Continuous\rquote is the usual setting and means that the monitor is expected to be per
forming the function selected above at all times and should one or more of the daemons fail or not be running it will be automatically restarted. By contrast \lquote Triggered\rquote
means that the decision about whether the daemons should actually be active is devolved to an external triggering mechanism.
\par }{\b\insrsid150409 Triggers }{\insrsid150409 \endash This small section lets you select which triggers will apply if the run mode has been set to \lquote triggered\rquote

\par }{\b\insrsid150409 Source Type}{\insrsid150409 \endash 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 affe
cts which set of options are shown in the next tab.
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 supp
ort 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.
\par }{\b\insrsid150409 Device Format}{\insrsid150409 \endash 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.
\par }{\b\insrsid150409 Capture Palette}{\insrsid150409 - 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.
\par }{\b\insrsid150409 Capture Width/Height}{\insrsid150409 - The dimensions of the video str
eam 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.
\par }{\b\insrsid150409 Orientation}{\insrsid150409 \endash If your camera is mounted upside d
own 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 t
he 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 \lquote Rotate Right\rquote
here then set the height to be 352 and width to be 288.
For remote cameras use these fields to enter the full URL of the camera. Basically if your camera is at }{\cs16\ul\cf2\insrsid150409 http://camserver.home.net:8192/cameras/camera1.jpg}{\insrsid150409 then these fields will be camserver.home.net, 819
2 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 <username>:<password>@<hostname>.com.
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.

- This relates to the timestamp that is applied to each frame. It is a \lquote sprintf\rquote style string. It is actually passed through sprintf and then through printf to add t
he 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\rquote
t want a timestamp or have a camera that puts one on itself then leave this field blank.
- 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
- 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 \lquote n\rquote images are kept, ready to be resurre
cted 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
l
ot of memory. A value of no more than 100 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.
\par }{\b\insrsid150409 Warm-up Frames }{\insrsid150409 - This specifies how many frames the analysis daemon should process but not examine when it starts. This allows it to g
enerate 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.
- 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 yo
u 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
t
he 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 yo
u
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 t

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 ser
ver. 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 d
e
vice. 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 con
figuration option that allows you to turn this limiting off in the event of an alarm.
\par }{\b\insrsid150409 FPS Report Interval}{\insrsid150409 - 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 f
or 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.
\par }{\b\insrsid150409 Reference Image Blend %ge}{\insrsid150409 - 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\rquote
s part in the reference image will diminish by a factor of 0.9 each time round. So a typical reference ima
ge 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
w
ill 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.

f
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 st
a
te 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.

\par 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.
\par 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.
\par 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
w
e 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
\rquote Monitor\rquote , which will ensure that one or more appropriate daemons are started automatically.
\par 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.
\par 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.

if you have cameras set up to support them. Once you have one or more monitors you may notice the '<n> 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

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.

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. Cli
ck 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. B
e
neath 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 quit
e a few, so now is a good time to go through them. The options are as follows.
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.
: 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.
\par }{\ul\insrsid150409 Inclusive}{\insrsid150409 : 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 t
he 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
t
ree 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 altog
: 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 onl
y
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
: 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 value
s
. 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
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 c
rner. 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 alar
ms 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.
\par }{\ul\insrsid150409 Inactive }{\insrsid150409 : This final zone type is the opposite of Active. In this zone ty
pe 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
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 do 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 except
ion 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.
\par }{\b\insrsid150409 Units}{\insrsid150409 - This setting which details whether certain of the following settings are in Pixels or Percent of the frame. In general \lquote Pixels\rquote
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 and refine any gaps. Repeated flipping between the settings will cause rounding errors, as ZoneMinder in general is not at home to Mr Floating Po
int for reasons of performance. }{\insrsid150409
Note, the sense of the percentage values changed in version 1.19.0. Prior to that percentages referred to the area of the image as a whole, whereas it now only refers to the area of the zone. This makes trying to work out necessary sizes rather easier.}{
- 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 max
ima are at the bottom right rather than in a Cartesian style.
\par }{\b\insrsid150409 Alarm Colour }{\insrsid150409 - 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 you
r 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.
\par }{\b\insrsid150409 Alarm Check Method }{\insrsid150409 \endash This is a new addition to Zone definitions. It allows you to sp
ecify 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 \lquote AlarmPixels\rquote , \lquote FilteredPixels\rquote and
\lquote Blobs\rquote and depending on which opti
on 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 \lquote blobs\rquote
. Blob analysis is the method ZoneMinder has always used previously
(before it became optional) and so this is the 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 mo
re useful alarm related features such as highlighted analysis images are only available with the \lquote Blob\rquote setting.
\par }{\b\insrsid150409 Min/Maximum Alarm Threshold}{\insrsid150409 \endash These setting are used to define limits for the difference in value between a pixel and its predecessor in the re
ference 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
a
n 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
- 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 o
f 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 su
den 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 p
ixels is however a very brute force method of detection as many small events dispersed widely are not distinguished from a compact one.
\par }{\b\insrsid150409 Filter Width/Height}{\insrsid150409 \endash To improve detection of valid event ZoneMinder applies several other functions to the data to impro
ve 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 a
nd 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.
\par }{\b\insrsid150409 Min/Maximum Filtered Area}{\insrsid150409 \endash These are two additio
nal 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 Alarm
ed Area and in general they should be smaller or the same.
\par }{\b\insrsid150409 Min/Maximum Blob Area}{\insrsid150409 - 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 othe
r 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 gener
ated. Of these only the Minimum is likely to be very useful.
\par }{\b\insrsid150409 Min/Maximum Blobs }{\insrsid150409 - 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.
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 Mon
itor 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 conta
i
n a heading, an image from your monitor, a status and a list of recent 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 opti
on 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.
\par 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 con
t
ains 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 \lquote cooling down\rquote , 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.
\par 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 \lquote options\rquote
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 i
n 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 th
is 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.
\par Below the status is a list of recent events that have occ
urred, by default this is a listing of just the last 10 but clicking on 'All' will give you a full list and 'Archive' will take you to the event archive for this monitor, more on this later. Clicking on any of the column headings will sort the events a
ppropriately.
\par 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.
\par 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 zon
e 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.
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 windo
w
. 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 t
h
e 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 c
hoose to view events here or delete them as before.
\par 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. Filter
ing 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.
\par 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, '
W
eekday' 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 Wedn
e
sday' 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 \lquote -3 day\rquote
or similar with easily parseable numbers and units. are in England
\par 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 sp
ecified, 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'.
\par 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 con
ent 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 cause
d
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 o
f these tokens.
\par 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.

n 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 wil
l
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
b
andwidth 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.
\par 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. Clicki
ng 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 'Sta
t
s' 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 th
e 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).
\par These last two op
tions 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 importa
nt 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.
\par The final option of generating an MPEG video is still somewhat experimental and its 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. T
h
is 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 configura
tion which additional options you may wish to include to suit your preferences.
\par 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, a
nd 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.

vered by the tutorial is the options and user section. If you are running in authenticated mode and don\rquote
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.
\par 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 \lquote ?
llowing 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.
\par If you have changed the value of an option you should then \lquote save\rquote it. A number of the option groups will then prompt you to let you know that the option(s) you have changed w
ill 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 an
d 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.
\par One of the options you may notice in the \lquote System\rquote tab allows you to specify the default langu
age 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 Engli
s
h 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 ZoneMinde
r build directory where the parts represented by the \lquote *\rquote
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 ava
ilable 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.
\par As mentioned above, you may also see a \lquote users\rquote 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 tempo
r
arily 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 th
at 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.
\par There are also four values that define the user permissions, these are \lquote stream\rquote , \lquote events\rquote , \lquote monitors\rquote and \lquote system\rquote Each can have values of \lquote none\rquote , \lquote view\rquote or \lquote edit
\rquote apart from \lquote stream\rquote which has no \lquote edit\rquote setting. These values cover access to the following areas; \lquote stream\rquote defines whether a user is allowed to view the \lquote live\rquote
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 \lquote none\rquote . The \lquote events\rquote setting determines whether a user can view
and modify or delete any retained historical events. The \lquote monitors\rquote setting specifies whether a user can see the current monitor settings and change them. Finally the \lquote system\rquote
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-
\rquote system\rquote 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 \lquote monitors\rquote
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 \lquote system\rquote privileges then the \lquote monitors ids\rquote
setting is ignored and has no effect.\rquote
\par That\rquote 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 tho
usands 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.

In case you are having problems here are some things to try. If these don't work then check the ZoneMinder FAQ at }{\field\flddirty{\*\fldinst {\insrsid150409 HYPERLINK "http://www.zoneminder.com/faq.html" }{\insrsid354063 {\*\datafield
.html 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. The best places to look for errors are in the system err
or 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.
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 <device_no> -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 Z
M_STRICT_VIDEO_CONFIG in zmconfig.pl or the \lquote options\rquote tab.
Start simple. Begin with a single monitor and single zone. You can run the zmc capture daemon from the command line as 'zmc --device 0' (or whatever your video device is). If it returns immediatel
y 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, bew
are 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!

e 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.

mmon 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 follo
w
ing 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 lar
g
e 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 http://www.redhat.com/docs/manuals/database/RHDB-2.1-Manu
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. Note, this error also sometime occurs if
you have an old shared memory segment lying around from a previous run that is too small. Use the ipcs and ipcrm system commands to check and remove it if necessary.

s 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 '<?php echo $value ?>', it will be something like this '<
?= $value ?>' which is easier and quicker to write as well as being neater. More information about this directive can be seen at the following location, }{\cs16\ul\cf2\insrsid150409 http://www.php.{\*\bkmkstart _Hlt42867874}n{\*\bkmkend _Hlt42867874}

wever 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 sometime
s
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 hav
e
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 sho
rt 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.

\par 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. 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.

al 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\rquote

cause 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 usu
a

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 installe

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\rquote
s associated httpd process, continue to grow in memory size until they kill the system. This a
ppears to be a bug in early versions of 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 i
t
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-rand
o
m 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 i
s
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

the 'asf' video format. I have al
so 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 stre

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 disappe

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 takin

\rin0\lin714\itap0 \f1\fs20\lang2057\langfe1033\cgrid\langnp2057\langfenp1033 {\insrsid150409 Optimisations and Performance Improvements. T
his 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 d
a
emons 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 cer
t
ain 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
t
he 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
o
ne 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 ble
n
ding 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 optimis
ations (along with other common sense ones such as not maintaining a reference image in \lquote Record\rquote
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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Remote Authentication. This document has previously indicated that basic authentication for network cameras could be used by
entering a hostname of the form of <user>:<pass>@<hostname>. 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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Filter Date Parsing. The zmfilter.pl date parsing now correctly reports when dates or times which it cannot parse are used.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}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 affect
d 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
l
eft 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 d

r example \lquote cat\rquote is in the set of \lquote cat, dog, cow, horse\rquote . You can also use regular expressions so \lquote cat\rquote matches \lquote ^c.*\rquote . The \lquote not in set\rquote and \lquote not matches\rquote

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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}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
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 desi
rable. 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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Monitor Name Constraint. The name given to a monitor is used in file paths and sev
eral 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.
onally 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-stampi
n
g 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 i
mage at it\rquote
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 c
onfiguration 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 im
pact either way.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Double Buffered Stills View. The stills view has now been restructured to allow a do
uble 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 pla
tforms. Whether ZoneMinder uses double buffering or not is controlled by the ZM_WEB_DOUBLE_BUFFER configuration option.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Fixed Length Event Bug. A bug was reported whereby the fixed length events that could be specified for use in Record or Mocord mode cou
ld 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.
Pending Process Bug. A bug was found whereby a process that was scheduled to be started in the future (due to repeated failures) would drop out of the pending queue if a further explicit restart was attempted. This is now fixed.
Strsignal Function. The strsignal function was included from version 1.17.1 however this is not ubiquitous on all distributions. The existence of this function is now tested for by the configure script and it is not used if not present.

s counterpart in the reference image) existed only in a \lquote minimum\rquote 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.

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
t
o 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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}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 ima
ge will be being searched for. To avoid this you can use the new \lquote zmupdate.pl\rquote utility to rename all your old images by doing \lquote perl zmupdate.pl \endash r\rquote as an appropriately privileged or root user.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Force Java. Previously ZoneMinder could be forced to override it\rquote
s detection of browser capabilities to prevent the Cambozola Java applet being used. However sometimes the opp
osite 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 \lquote auto\rquote , \lquote yes\rquote or \lquote no\rquote
to be used to provide all alternatives.

\rin0\lin714\itap0 \f1\fs20\lang2057\langfe1033\cgrid\langnp2057\langfenp1033 {\insrsid150409 Version Numbering. ZoneMinder version numbers have now changed. This is to allow more frequent \lquote point\rquote
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\insrsid150409 x.y.z}{\insrsid150409 format where a change in }{\i\insrsid150409 x}{\insrsid150409 signifies a major fundamental or architectural rework, a change in }{\i\insrsid150409 y}{\insrsid150409 will indicate a new release containing incre

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.
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\insrsid150409 nn_mm}{\insrsid150409
.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.

olations 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 a
nd only the very few where the fix would be significantly less optimal than the problem remain.
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 containi
ng 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.

\rin0\lin714\itap0 \f1\fs20\lang2057\langfe1033\cgrid\langnp2057\langfenp1033 {\insrsid150409 Run States. Instead of the old \lquote start/stop\rquote
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 function
s 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.
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 continuou
s
ly 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 second
s 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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}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 t
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 the
se 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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Scaleable Streams. Ev
ent 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
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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Scaleable/Variable MPEG generation. Generation of MPEG videos now also allo
ws 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.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Tabbed Monitor options. Specification and modification of monitors is now in a tabbed form for easier navigation.

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 wa
s about without having to watch the stream or view all the static images.
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.

OPT_MPEG bug. A bug was reported (by Fernando Diaz) where the results of the ZM_OPT_MPEG configuration variable was not correctly imported into the scripts. This now happens as intended.
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 o
f 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 correc

Historically ZoneMinder has only supported the Berkeley mpeg encoder which was slow and rather limited. ZoneMinder now supports the ffmpeg encoder as we
ll 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
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, a
nd 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.
Previously ZoneMinder used quite a loose method for calculating the differences between two colour images. This was basically averaging the di
fferences 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 inst
e
ad. 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 par
tially converted back to get the Y value. This is currently very inefficient and needs to be optimised.
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.

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 i

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 o

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 generati

\rin0\lin720\itap0 {\insrsid150409 Added zmu -q/--query option - There is now a new query option for zmu. When combined with -d it gives the con
fig 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 information for a video device by default. This now requires the -q o

\rin0\lin720\itap0 {\insrsid150409 Upgrade note - If you have installed 0.9.7 and wish to save your configuration then copy your existing zmconfig.txt file over to your 0.9.8 directory and before running zmconfig.pl.
Added multiple options to zmu - You can now give multiple options to zmu and get all the responses at once. However this is currently in a deterministic order and not related to the order you give them.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Added -v/--verbose option to zmu - Zmu has been mad
e more human friendly though it still remains primarily for daemon use. Giving the -v or --verbose option prints out a bit more as a response to each command.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Add -d/--device to zmu - This option is designed to allow you to get your video device working

\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Added FPS in status field - The status field in the web monitor views now contains an FPS setting as well as the status.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Zmconfig changes - zmconfig handles missing options better and rewrites config file even in non-interactive mode.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Fixed config problems in zmcfg.h - Some config was not being set up correctly in zmcfg.h.
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.
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.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}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.

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.
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.
ration 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.

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.
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.

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.
\pnrpnbr0\pnrpnbr0\pnrpnbr0\pnrstop36\rin0\lin720\itap0 {\insrsid150409 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.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Comments - Needs many more, but that's just me I'm hopeless at commenting things out. I'll get round
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.
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.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Zone Definitions - Allow zones to be defined according to a colour coded bitma
p 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.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Mouseover help - A bit more help popping up when you mouseover things would be handy. A bit more help full stop actually.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}WAP interface - A bit of a crusade of mine I'm afraid. I'd like to put a WML interface on to allow you to view event listing and perhaps the mos
t significant image from each event on your phone. Also simple management. From version 0.9.7 there is a very basic crude initial version that probably won't work with your phone but its there as a testbed.
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.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Extend the API. Well ok it's not really got an A
PI 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.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Create .rpm packages (as there can be several dependencies) and maybe other types of packages also, e.g. for Debian distributions.
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 o
f magic, and recommend settings that will support this selection automatically thereafter. The hooks for this are already in to some extent.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033 \hich\af2\dbch\af0\loch\f2 o\tab}Add sound support to allow a captured audio channel to be associated with a video device.
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).
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.
