\par }{\insrsid7562726 A few months back my garage was burgled and all my wine and power tools were nicked! I realised shortly after that if I'd just had a camera overlooking the door then at least I'd
have know exactly when and who did the dirty deed. And so ZoneMinder was born. It's still a baby but hopefully it can grow up to be something that can be genuinely useful and maybe one day either prevent similar incidents or perhaps bring some perpetrator
s 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 camera pe
r 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 comes w
ith a user friendly and comprehensive PHP based web interface allowing you to control and monitor your cameras from home or even at work or on the road. It supports variable web capabilities based on available bandwidth. The web interface also allows you
t
o view events that your cameras have captured and archive them or review them time and again, or delete the ones you no longer wish to keep. The web pages directly interact with the core daemons ensuring full co-operation at all times. ZoneMinder can even
be installed as a system service ensuring it is right there if your computer has to reboot for any reason.
\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 c
an eliminate false positives whilst ensuring that anything you don't want to miss will be captured and saved. ZoneMinder allows you to define a set of 'zones' for each camera of varying sensitivity and functionality. This allows you to eliminate regions t
hat 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 {\insrsid7562726 HYPERLINK http://www.zoneminder.com/donate.html }{\insrsid8067092 {\*\datafield
\insrsid7562726 where any donations will be appreciated and will help to fund future improvements of ZoneMinder.}{\insrsid1131838 This would be especially appreciated if you use ZoneMinder as part of your business or to protect your property.}{

\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 }{\insrsid12872856 runtime;}{\insrsid7562726 this is because it needs to use the MySQL header files.}{
\insrsid10433091 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.}{\insrsid7562726
ed at least libjpeg.a which I think come as standard nowadays with most distributions. It also uses the netpbm utilities in a very limited way to generate thumbnails under certain circumstances though this can be modified.
\par ZoneMinder can generate MPEG videos if necessary, for this you'll need either ffmpeg (recommended) or the Berkeley MPEG encoder}{\insrsid10433091 (mpeg_encode)}{\insrsid7562726 . If you don't have either}{\insrsid10433091 ,}{\insrsid7562726
don't worry, as the options will be hidden and you'll not }{\insrsid1131838 really }{\insrsid7562726 miss much. The web interface uses PHP and so you need t
hat in your apache or other web server as well, make sure MySQL support is available either statically or as a module. There are also various perl modules that you may need that vary depending on which options you choose on installation, for more details
\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\insrsid7562726
http://www.charliemouse.com/code/cambozola/}{\insrsid7562726 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 interfa
ce. I don't have a lot of cameras myself so I've not had change to test it with a huge range personally however there is a list of devices that are definitely known to work on the web site. Please let me know if your camera }{\insrsid10433091 works and }{
\insrsid7562726 is not listed. You do need to have Video 4 Linux installed. I've not got too many machines so I've only really used it on }{\insrsid10433091 various }{\insrsid7562726 RedHat}{\insrsid10433091 distributions}{\insrsid7562726 , which }{
\insrsid10433091 seem to }{\insrsid7562726 have everything there by default I think. SlackWare does need a bit more tinkering than other distributions; the
re 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.

\par }{\insrsid7562726 where --with-mysql identifies }{\insrsid10433091 the root directory }{\insrsid7562726 where you have installed MySQL (usually /usr), --with-webdir i
s the directory to which you want to install the PHP files, and --with-cgidir is the directory to which you want to install CGI files. These directories could be /var/www/html/zm and /var/www/cgi-bin for example. There are also two further arguments you c
an add if your web user and group are not both 'apache'. These are --with-webuser and --with-webgroup. Type
\par That's the build configuration sorted out. The next thing you have to do is do a little more runtime specific configuration. ZoneMinder }{\insrsid12872856 configuration}{\insrsid7562726
\par }{\insrsid7562726 to get it started. It is an interactive utility and will pr
ompt you by asking you various questions. For most questions typing '?' will give you additional help if you need it. Once you've answered all the questions it will write out a configuration file called 'zmconfig.txt' and then process various files to sub
stitute the information in them. If you run it again it will remember your answers from. If you }{\insrsid10433091 just want to rerun the substitutions you}{\insrsid7562726 can run zmconfig.pl in non-interactive mode by typing
\par }{\insrsid7562726 which will just read your file and do the subst}{\insrsid10433091 i}{\insrsid7562726 t}{\insrsid10433091 ut}{\insrsid7562726 ions 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.}{\insrsid10433091 If you want to change just a few options and can\rquote t access the options dialog via the web you can ap
pend them as parameters to zmconfig and it will just ask you about those. So for example,}{\insrsid7562726

\par }{\insrsid7562726 Among the first questions zmconfig.pl
asks you are to do with the database and the next thing you should do is create it and the associated database users. You may notice that there are two sets of users and passwords. This is because the streaming server and utility binaries require only re
a
d access to the database so you may wish to create both a full access user and a limited access user. You can of course set both to the full access user. The included schema (zmschema.sql) can be used to actually create the tables required. The database i
s usually called just 'zm'.
\par }{\insrsid2780672 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 it for the first time the schema file should have your desired database na
me 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 }{\insrsid7562726 If you are upgrading from a previous version you can use
zmalter-x.y.z.sql to upgrade your database and make the necessary changes where x.y.z identifies the version of ZoneMinder you had installed previously. So if you are going from version 0.9.7 to version 0.9.11 you would run the scripts for all intervening
versions to get to the current one, i.e. zmalter-0.9.7.sql, zmalter-0.9.8.sql, zmalter-0.9.9.sql}{\insrsid2780672 and zmalter0.9.10.sql.
\par }{\insrsid7562726 You may need to supply a username and password to the mysql commands in the first place to give yourself sufficient privileges to perform the required commands. If you want to host your database on a different machine than that which Zon
eMinder is running on then use the hostname of the remote machine instead of localhost.

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\insrsid7562726 zmdc.pl}{\insrsid7562726 - This is the ZoneMinder Daemon Control script. This is used by the web interface and the zmpk

\par }{\b\insrsid7562726 zmfilter.pl}{\insrsid7562726 - This script controls the execution of saved filters and will be started and stopped by the
web interface based on whether there are filters that have been defined to be autonomous. This script is also responsible for the automatic uploading of events to a 3rd party server.
\par }{\b\insrsid7562726 zmaudit.pl}{\insrsid7562726 - This scri
pt is used to check the consistency of the event file system and database. It can delete orphaned events, i.e. ones that appear in one location and not the other as well as checking that all the various event related tables are in line. It can be run inte

actively or in batch mode either from the command line or a cron job or similar. In the zmconfig.pl there is an option to specify fast event deletes where the web interface only deletes the event entry from the database itself. If this is set then it is t
- This is an optional script that can be used to initiate and monitor X10 Home Automation style events and interface with an alarm system either by the generation of X10 signals on ZoneMinder events or by initiat
ing 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

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

in order to be given permissions to perform certain tasks. If you chose this mode then you will need to log in here. By default a fully privileged user \lquote admin\rquote has been created with a password also of \lquote admin\rquote
. You should change this password as soon as possible.
\par Once you\rquote ve logged in, or if you are running in un-authenticat

To use ZoneMinder properly you need to define at least one Monitor. Essentially, a monitor is associated with a camera and }{\insrsid13576447 can }{\insrsid7562726
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.

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 (note, you will have to additionally supply a u
sername and password to zmu if you are running in authenticated mode). You can then enter these values into the video related options of the monitor configuration panel. The 'device_no' referred to here is a number corresponding to the digit at the end of
your device file, so /dev/video0 has a 'device_no' of 0 etc. If 'zmu' gives you an error related to permissions run 'zmfix -a' to make sure you can access all the video devices.

}{\insrsid12872856 not be}{\insrsid12202642 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\insrsid12202642 Frame Skip }{\insrsid12202642 \endash This setting also applies only to }{\insrsid4203687 the }{\insrsid12202642 \lquote Record\rquote or \lquote Mocord\rquote }{\insrsid4203687
functions and specifies how many frames should be skipped in the recorded events. The default setting o
f 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 }{\insrsid1131838 t}{\insrsid4203687
hinking 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 frame rate. The alternate approach is to limit the capture frame rate which will ob
viously affect the rate at which frames are saved.}{\insrsid12202642
\par }{\b\insrsid4203687 Run Mode }{\insrsid4203687 \endash Two choices are available here. \lquote Continuous\rquote
is the usual setting and means that the monitor is expected to be performing 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 }{\insrsid4721303 mechanism.}{\insrsid4203687
\par }{\b\insrsid4721303 Triggers }{\insrsid4721303 \endash This small section lets you select which triggers will apply if the run mode has been set to }{\insrsid1131838 \lquote }{\insrsid4721303 triggered}{\insrsid1131838 \rquote }{\insrsid4721303
above. The most common trigger is X10 and this will appear here if you indicated that your system supported it during installation. Only X10 is }{\insrsid4721303\charrsid15420176 s}{\insrsid4721303 upported as a shipped trigger with }{\insrsid1131838 Z
oneMinder}{\insrsid4721303 at present but it is expected that other triggers will become available as necessary. You can also just use \lquote cron\rquote
\par }{\b\insrsid12202642 Source Type}{\insrsid12202642 \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 affects which set of }
{\insrsid1312060 options are shown in the next tab}{\insrsid12202642 .
For a local camera enter the device number that your camera is attached to. If it is /dev/video0 enter '0' etc. Some video devices, e.g. BTTV cards support multiple cameras}{\insrsid1312060 on one device}{\insrsid7562726 so in }{\insrsid1312060
this case enter the channel number in }{\insrsid7562726 the Channel box or leave it at zero if you're using a USB camera or one with}{\insrsid1312060 just one}{\insrsid7562726 channel.
\par }{\b\insrsid7562726 Device Format}{\insrsid7562726 \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\insrsid1312060 Capture Palette}{\insrsid1312060 - 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. }{\insrsid12872856 There is a slight performance penalty when using palettes other than grey or 24 bit colour as an internal conversion is involved. }{
\insrsid1312060 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\insrsid1312060 Capture Width/Height}{\insrsid1312060 - The dimensions of the video stream your camera will supply. If your camera supports several just enter the one
you'll want to use for this application, you can always change it later. However I would recommend starting with no larger than }{\insrsid14377348 320x240 or }{\insrsid1312060
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 197x3}{\insrsid14377348
33 should be avoided initially.}{\insrsid1312060
\par }{\b\insrsid1312060 Orientation}{\insrsid1312060 \endash If your camera is mounted upside down or at right angles you can use this field to specify a rotation that is app
lied to the image as it is captured. This incurs an additional processing overhead so if possible it is better to mount your camera the right way round if you can. If not set the orientation here. If you choose one of the rotation options remember to swit
ch 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\insrsid7562726 http://camserver.home.net:8192/cameras/camera1.jpg}{\insrsid7562726
then these fields will be camserver.home.net, 8192 and /cameras/camera1.jopg respectively. Leave the port at 80 if there is no s
pecial port required. If you require authentication to access your camera then add this onto the host name in the form <username>:<password>@<hostname>.com.
\par }{\b\insrsid14377348 Remote Image Colours }{\insrsid14377348 \endash Specify the amount of colours in the captured image. Unlike with local camer
as 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 }{\insrsid14377348 \lquote }{\insrsid7562726 sprintf}{\insrsid14377348 \rquote }{\insrsid7562726
style string. It is actually passed through sprintf and then through printf to add the monitor name so a format of '%%s - %y/%m/%d %H:%M:%S' }{\insrsid14377348 (note the double % at the beginning) }{\insrsid7562726
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.
\par }{\b\insrsid7562726 Timestamp Label X/Y}{\insrsid7562726 - 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. }{
\insrsid14377348 To place the timestamp at the bottom of the image use a value eight less than the image height.}{\insrsid7562726
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 resurrected on an alarm or just kept waiting to be analysed. It can be any value you l
ike with a couple of provisos, (see next options). However it is stored in shared memory and making it too large especially for large images with a high colour depth can use a lot of memory. A value of no more than 100 is usually ok.}{\insrsid14377348
If you find that your system will not let you use the value you want it is probably }{\insrsid1131838 because}{\insrsid14377348
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.}{\insrsid7562726
\par }{\b\insrsid7562726 Warm-up Frames }{\insrsid7562726 - This specifies how many frames the analysis daemon should process but not examine when it starts. This allows it to generate an accurate reference image from a series of images before looking too
carefully for any changes. I use a value of 25 here, too high and it will take a long time to start, too low and you will get false alarms when the analysis daemon starts up.
\par }{\b\insrsid7562726 Pre/Post Event Image Buffer}{\insrsid7562726 - These options determine how many frames from before
and after an event should be preserved with it. This allows you to view what happened immediately prior and subsequent to the event. A value of 10 for both of these will get you started but if you get a lot of short events and would prefer them to run to
gether to form fewer longer ones then increase the Post Event buffer size. }{\insrsid14377348 The pre-event buffer is a true buffer and should not really exceed half}{\insrsid7562726 the ring buffer size. }{\insrsid14377348
However the post-event buffer is just a count that is applied to captured frames and so can be managed more }{\insrsid1131838 flexibly. You}{\insrsid7562726 should also bear in mind the frame rate of the camera when choosing th}{\insrsid14377348 ese}{
\insrsid7562726 }{\insrsid14377348 values}{\insrsid7562726 . For instance a network camera capturing at 1FPS will give you 10 seconds before and after each event if you chose 10 here. This may well be
too much and pad out events more than necessary. However a fast video card may capture at 25FPS and you will want to ensure that this setting enables you to view a reasonable time frame pre and post event.
On some occasions you may have one or more cameras capable of high capture rates but find that you generally do not require this performance at all times and would prefer to lighten the load on your server. This option permits you to limit the maximum ca
p
ture rate to a specified value. This may allow you to have more cameras supported on your system by reducing the CPU load or to allocate video bandwidth unevenly between cameras sharing the same video device. This value is only a rough guide and the lower
the value you set the less close the actual FPS may approach it especially on shared devices where it }{\insrsid5585016 can be}{\insrsid7562726 difficult to synchronise two}{\insrsid5585016 or more}{\insrsid7562726
different capture rates precisely. There is a global configuration option that allows you to turn this limiting off in the event of an alarm.
- How often the current performance in terms of Frames Per Second is output to the system log. Not used in any functional way so set it to maybe 1000 for now. If you watch /var/log/messages (normally) you
will see this value being emitted at the frequency you specify both for video capture and processing.
\par }{\b\insrsid7562726 Reference Image Blend %ge}{\insrsid7562726 - 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}{\insrsid5585016 \rquote }{\insrsid7562726
s part in the reference image will diminish by a factor of 0.9 each time round. So a typical reference image will be 10% the previous image, 9% the one before
that and then 8.1%, 7.2%, 6.5% and so on of the rest of the way. An image will effectively vanish around 25 images later than when it was added. This blend value is what is specified here and if higher will make slower progressing events less detectable a
s
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 }{\insrsid5585016 (usually down) }{\insrsid7562726 later if necessary.

\par }{\b\insrsid7562726 X10 Activation String}{\insrsid7562726 - }{\insrsid5585016 The}{\insrsid7562726 contents of this field determine when a monitor }{\insrsid11086489 starts and/or stops being active when running in \lquote
Triggered; mode and with X10 triggers. T}{\insrsid7562726 he format of this string is as follows,
: If you simply enter a number then the monitor will be activated when an X10 ON signal for that unit code is detected and will be deactivated when an OFF signal is detected.
\par }{\ul\insrsid7562726 !n}{\insrsid7562726 : This inverts the previous mode, e.g. !5 means that the monitor is activated when an OFF signal for unit code 5 is detected and deactivated by an ON.
\par }{\ul\insrsid7562726 n+}{\insrsid7562726 : Entering a unit code followed by + means that the monitor is activated on receipt
of a ON signal for that unit code but will ignore the OFF signal and as such will not be deactivated by this instruction. If you prepend a '!' as per the previous definition it similarly inverts the mode, i.e. the ON signal deactivates the monitor.
\par }{\ul\insrsid7562726 n+<seconds>}{\insrsid7562726 : As per the previous mode except that the monitor will deactivate itself after the given number of seconds.
\par }{\ul\insrsid7562726 n-}{\insrsid7562726 : Entering a unit code followed by - means that the monitor is deactivated on receipt of a OFF signal for that unit code but will ignore t
he ON signal and as such will not be activated by this instruction. If you prepend a '!' as per the previous definition it similarly inverts the mode, i.e. the OFF signal activates the monitor.
\par }{\ul\insrsid7562726 n-<seconds>}{\insrsid7562726 : As per the previous mode except that the monitor will activate itself after the given number of seconds.
You can also combine several of these expressions to by separating them with a comma to create multiple circumstances of activation. However for now leave this blank.
\par }{\b\insrsid7562726 X10 Input Alarm String}{\insrsid7562726 - This has the same format as the previous field but instead of activating the monitor with will cause a forced alarm to be generated and an event recorded if the monitor is Active. The same }{
\insrsid12872856 definition as above applies}{\insrsid7562726 except that for activated read alarmed and for deactivated read unalarmed(!). Again leave this blank for now.
\par }{\b\insrsid7562726 X10 Output Alarm String}{\insrsid7562726 - This X10 string also has the same format as the two above options. However it works in a slightly different way. Instead of ZoneMinder reacting to X10 events this opt
ion controls how ZoneMinder emits X10 signals when the current monitor goes into or comes out of the alarm state. Thus just entering a number will cause the ON signal for that unit code to be sent when going into alarm state and the OFF signal when coming
out of alarm state. Similarly 7+30 will send the unit code 7 ON signal when going into alarm state and the OFF signal 30 seconds later regardless of state. The combination of the X10 instruction allows ZoneMinder to react intelligently to, and also assume
control of, other devices when necessary. However the indiscriminate use of the Input Alarm and Output Alarm signals can cause some horrendous race conditions such as a light going on in response to an alarm which then causes an alarm itself and so on. Th
us some circumspection is required here. Leave this blank for now anyway.

\insrsid7562726 and you get to other functions of ZoneMinder by choosing the appropriate one. Describing them left to right, they are as follows.
\par The first column is the Id, clicking on this gives you the opportunity to edit any of the settings you have just defined your monitor to have.
\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}{\insrsid595092 along with recent events}{\insrsid7562726 . 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 runni
n
g but no zma (analysis) daemon and green means both are running. In our case it is red because we defined the Monitor to have a Function of None so no daemons are required. To get the daemons up and running you can either click on the source listed in the
Source column and edit the monitor properties or click on the Function listed and change it to }{\insrsid595092 \rquote Monitor\rquote }{\insrsid7562726 , 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.
\par Once you have changed the function of your monitor, the main console window will be updated to reflect this change. If your device status does not go green then check your system and web server logs to see if it's something obvious.
\par You can now add further monitors if you have cameras set up to support them. Once you have one or more monitors you may notice the '<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 still image from each in turn. There may also be a link titled \lquote Montage\rquote
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. Click on the Zones column for your monitor and
you should see a small popup window appear which contains an image from your camera overlain with a stippled pattern representing your zone. In the default case this will cover the whole image and will be red. Beneath that will be a table containing a lis
t
ing of your zones. Clicking on either the relevant bit of the image or on the Id or Name in the table will bring up another window where you can edit the particulars for your Zones. As you can see there are quite a few, so now is a good time to go through
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.
: This zone type can be used for any zones that you want to trigger an alarm only if at least one other Active zone has already triggered one. This might be for example to cover an area of the image like a plant or tree which moves a lo
t and which would trigger lots of alarms. Perhaps this is behind an area you'd like to monitor though, in this case you'd create an active zone covering the non-moving parts and an inclusive zone covering the tree perhaps with less sensitive detection set
tings also. If something triggered an alarm in the Active zone and also in the Inclusive zone they would both be registered and the resulting alarm would be that much bigger than if you had blanked it out altogether.
\par }{\ul\insrsid7562726 Exclusive}{\insrsid7562726 : The next zone Type is Exclus
ive. 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 camer
a
covering my garden I keep watch for a hedgehog that visits most nights and scoffs the food out of my cats bowls. By creating a sensitive Exclusive zone in that area I can ensure that a hedgehog alarm will only trigger if there is activity in that small a
rea. If something much bigger occurs, like someone walking by it will trigger a regular alarm and not one from the Exclusive zone. Thus I can ensure I get alarms for big events and also special small events but not the noise in between.
\par }{\ul\insrsid7562726 Preclusive}{\insrsid7562726 : This zo
ne 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 n
o
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 zo
n
e. However in some cases that zone may cover an area where the area of variable illumination occurs in different places as the sun and/or shadows move and it thus may be difficult to come up with general values. Additionally, if the sun comes out rapidly
hen although the initial change may be ignored in this way as the reference image catches up an alarm may ultimately be triggered as the image becomes less different. Using one or more Preclusive zones offers a different approach. Preclusive zones are des
i
gned to be fairly small, even just a few pixels across, with quite low alarm thresholds. They should be situated in areas of the image that are less likely to have motion occur such as high on a wall or in a corner. Should a general illumination change oc
c
ur they would be triggered at least as early as any Active zones and prevent any other zones from generating an alarm. Obviously careful placement is required to ensure that they do not cancel any genuine alarms or that they are not so close together that
any motion just hops from one Preclusive zone to another. As always, the best way is to experiment a little and see what works for you.
\par }{\ul\insrsid7562726 Inactive }{\insrsid7562726 : This final zone type is the opposite of Active. In this zone type no alarms will ever be reported. You can cr
eate an Inactive zone to cover any areas in which nothing notable will ever happen or where you get constant false alarms that don't relate to what you are trying to monitor. An Inactive zone can overlay other zone types and will be processed first.

ioned 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 }{\insrsid4344454 do }{\insrsid7562726
not overlap. This helps avoid repeated
duplicate processing of the same area. For instance an Inclusive zone overlaying an Active zone when all other settings are the same will always trigger when the Active zone does which somewhat defeats the object of the exercise. One exception to this is
Preclusive zones. These may be situated within Active areas are they are processed first and if small may actually save processing time by preventing full analysis of the image.
\par }{\b\insrsid7562726 Units}{\insrsid7562726 - This setting which details whether certain of the following settings are in Pixels or Percent of the frame. In general }{\insrsid12872856 \lquote P}{\insrsid7562726 ixels}{\insrsid12872856 \rquote }{
\insrsid7562726 is more precise whereas percentages are easier to use to start with}{\insrsid4344454 or if you change image sizes frequently}{\insrsid7562726 . If you change this setting all appropriate values below are redisplayed in the correct con
text. A good tip would be to initially enter the settings in Percent and then change to Pixels and refine any gaps. Repeated flipping between the settings will cause rounding errors, as ZoneMinder in general is not at home to Mr Floating Point for reasons
- Following the units the next four settings define the bounds of the Zone in the monitor frame and are self-explanatory with the exception of the fact that the minima are at the top left of the frame and the maxima are at
the bottom right rather than in a Cartesian style.

ature 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 }{\insrsid8589730 and depending on which option is chosen some of the following other settings may become unavailable.}{\insrsid2111957
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 is
olated 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 .}{\insrsid8589730
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 more useful a
larm related features such as highlighted analysis images are only available with the \lquote Blob\rquote setting.}{\insrsid2111957

ge. For greyscale images this is simple but for colour images the colours are averaged first, originally this used an RMS (root mean squared) algorithm but calculating square roots mugs performance and does not seem to improve detection. Using an average
d
oes means that subtle colour changes without any brightness change may go undetected but this is not the normal circumstance. There is also the option to use a more sophisticated integer algorithm to calculate a Y (or brightness) value from the colours th
- The following two settings define the minimum and maximum number of pixels that exceed this threshold that would cause an alarm. If the units are Percent this (and following options) refers to the percentage of the frame
and not the zone, this is so these values can be related between zones. The minimum value must be matched or exceeded for an alarm to be generated whereas the maximum must not be exceeded or the alarm will be cancelled. This is to allow for sudden change
such as lights coming on etc, which you may wish to disregard. In general a value of zero for any of these settings causes that value to be ignored, so you can safely set a maximum to zero and it will not be used. The use of just a number of pixels is ho
wever a very brute force method of detection as many small events dispersed widely are not distinguished from a compact one.
\par }{\b\insrsid7562726 Filter Width/Height}{\insrsid7562726 \endash To improve detection of valid event ZoneMinder applies several other functions to the data to improve its abil
ity 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 }{\insrsid4344454 expressed in }
{\insrsid7562726 pixels and should be fairly small, and an odd number}{\insrsid4344454 , three or five is a good value to choose }{\insrsid1131838 initially}{\insrsid7562726
\par }{\b\insrsid7562726 Min/Maximum Filtered Area}{\insrsid7562726 \endash These are two additional bounds
that specify the limits of pixels that would cause an alarm after this filtering process. As the filtering process can only remove alarmed pixels it makes no sense for the Minimum and Maximum Filtered Area to be larger than the equivalent Alarmed Area and
in general they should be smaller or the same.
\par }{\b\insrsid7562726 Min/Maximum Blob Area}{\insrsid7562726 - The next step in the analysis phase is the collation of any remaining alarmed areas into contiguous blobs. This process parses the image and forms any pixels that adjoin other alarmed p
ixels into one or more larger blobs. These blobs may be any shape and can be as large as the zone itself or as small as the filtered size. The Minimum and Maximum Blob Size settings allow you to define limits within which an alarm will be generated. Of th
ese only the Minimum is likely to be very useful.
\par }{\b\insrsid7562726 Min/Maximum Blobs }{\insrsid7562726 - 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 }{\insrsid4344454
starts or continues }{\insrsid7562726 an alarm event.

is wrong so look in your system error log and check for or report anything unusual. The centre of the window will have a tiny frame that just contains a status; this will be 'Idle', 'Alarm' or 'Alert' depending on the function of the Monitor and what's go
ing 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 }{\insrsid4344454 \lquote }{\insrsid7562726 cooling down}{\insrsid4344454 \rquote }{

uired. You can also specify a sound file in the configuration, which will be played when an alarm occurs to alert you to the fact if you are not in front of your computer. This should be a short sound of only a couple of seconds ideally. Note that as the
s
tatus is refreshed every few seconds it is possible for this not to alert you to every event that takes place, so you shouldn't rely on it for this purpose if you expect very brief events. Alternatively you can decrease the refresh interval for this windo

\par Below the status is a list of recent events that have occurred, 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 appropriately.
\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 fin
ally 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 zone are added together, Active zones scores are added unchanged, Inclusive zones are halved first and Exclusive
zones are doubled. In reality values are likely to be much less than 100 but it does give a simple indication of how major the event was.

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

hich can be sorted by clicking on the heading. Also this window will not refresh automatically, rather only on request. Other than that, you can choose to view events here or delete them as before.
\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. Filtering itself is fairly simple; you first choose how many expressions you'd like your filter to contain. Changin
g
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 exp

hich you can use to include or exclude Archived events. In general you'll probably do most filtering on un-archived events. Once your filter is specified, clicking 'submit' will filter the events according to your specification. If you have created a filt
er 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 fi
lter automatically applied in order to delete events or upload events via ftp to another server and mail notifications of events to one or more email accounts. In most cases you can specify your preferences for upload formats and email content during conf
i
guration time (make sure you type '?' to get help on options). Emails and messages (essentially small emails intended for mobile phones or pagers) have a variety of tokens that can be substituted for various details of the event that caused them. This inc
ludes links to the event view or the filter as well as the option of attaching images or videos to the email itself. See the included templates zmconfig_eml.txt and zmconfig_msg.txt for a fuller explanation of the availability and meaning of these tokens.
\par F
iltering 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 instan
ce events that happen during weekdays or at certain times of the day are highlighted, uploaded or deleted.
From the monitor or filtered events listing you can now click on an event to view it in more detail. If you have streaming capabil
ity you will see a series of images that make up the event. You will also see a link to allow you to view the still images themselves. If you don't have streaming then you will be taken directly to this page. The images themselves are thumbnail size and d
e
pending on the configuration and bandwidth you have chosen will either be the full images scaled in your browser of actual scaled images. If it is the latter, if you have low bandwidth for example, it may take a few seconds to generate the images. If thum
bnail 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 contai
n an overlay outlining the blobs that represent the alarmed area. This outline is in the colour defined for that zone and lets you see what it was that caused the alarm. Clicking on one of the thumbnails will take you to a full size window where you can s
e the image in all its detail and scroll through the various images that make up the event. If you have the ZM_RECORD_EVENT_STATS option on, you will be able to click the 'Stats' link here and get some analysis of the cause of the event. Should you determ
i
ne that you don't wish to keep the event, clicking on Delete will erase it from the database and file system. Returning to the event window, other options here are renaming the event to something more meaningful, refreshing the window to replay the event
stream, deleting the event, switching between streamed and still versions of the event (if supported) and generating an MPEG video of the event (if supported).
\par These last two options require further explanation. Archiving an event means that it is kept to o
ne side and not displayed in the normal event listings unless you specifically ask to view the archived events. This is useful for keeping events that you think may be important or just wish to protect. Once an event is archived it can be deleted or unarc
hived 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 }{\insrsid12872856 its}{\insrsid7562726 usefulness may vary. It can use either the Berkeley MPEG encoder or the faster and new ffm
peg 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 video
s
created by this method will be very quick. However when using the ffmpeg encoder, ZoneMinder will attempt to match the duration of the video with the duration of the event. This has the useful effect of making the video watchable and not too quick while
having the unfortunate side effect of increasing file size and generation time. Ffmpeg in particular has a particularly rich set of options and you can specify during configuration which additional options you may wish to include to suit your preferences.
\par B
uilding an MPEG video, especially for a large event, can take some time and should not be undertaken lightly as the effect on your host box of many CPU intensive encoders will not be good. However once a video has been created for an event it will be kept
so subsequent viewing will not incur the generation overhead. I will be the first to admit that this area of the package is not particularly well implemented and needs work, and probably a better encoder. Videos can also be included in notification emails
however care should be taken when using this option as for many frequent events the penalty in CPU and disk space can quickly mount up.

\rquote link following each description to get a fuller explanation about each option. This
is the same as you would get from zmconfig.pl. A number of option groups have a master option near the top which enables or disables the whole group so you should be aware of the state of this before modifying options and expecting them to make any diffe
rence.
\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 will require a system restart. This is not done automatically in case you wil

ons will still be using the old values and this can lead to data inconsistency or loss.
\par }{\insrsid15289376 One of the options you may notice in the \lquote System\rquote tab allows you to specify the default language for your installation of ZoneMinder. Versions 1.17.0 and later support m
ultiple languages but rely on users to assist in creating language files for specific languages. To specify a language you will have to give the applicable code, thus for UK English this is en_gb, and for US English it would be en_us}{\insrsid12607833
, if no language is given then UK English is assumed}{\insrsid15289376
. Most languages will be specified in this nn_mm format and to check which languages are available look for files named zm_lang_*.php in the ZoneMinder build directory where the parts represented by the \lquote *\rquote would be what you wo
uld enter as a language. This is slightly unwieldy and will probably be improved in future to make it easier to determine language availability. On checking which languages are available it may be that your preferred language is not currently included and
if this is the case please consider doing a translation and sending it back to it may be included in future releases. All the language elements are given in the zm_lang_en_gb.php file along with a few notes to help you understand the format.
\par }{\insrsid7562726 As mentioned above, you may also see a \lquote users\rquote tab}{\insrsid15289376 in the Options }{\insrsid12607833 area}{\insrsid7562726
. 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 yo
u have created another fully privileged user to take over the same role. Each user is defined with a name and password (which is hidden) as well as an enabled setting which you can use to temporarily enable or disable users, for example a guest user for l
imited time access.}{\insrsid15289376
As well as that there is a language setting that allows you to define user specific languages. Setting a language here that is different than the system language will mean that when that user logs in they will have the web interface pres
ented in their own language rather than the }{\insrsid12607833 system }{\insrsid15289376 default, if it is available. }{\insrsid1131838 Specifying}{\insrsid12607833
a language here is done in the same way as for the system default language described above.}{\insrsid7562726
\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 vide
o 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 }{\insrsid12872856 \lquote }{

\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 thousands of events build up is not good for the database or your
file system so you should endeavour to either prevent spurious events from being generated in the first place or ensure that you housekeep them strictly.

gle 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 immediately there's a problem so check the logs, if it stays up then your video configuration is probably ok. To get m

're checking things as root make sure that you clean up afterwards!
Web server. Ensure that your web server can serve PHP files. It's also possible that your php.ini file may have some settings which break ZoneMinder, I'm not a PHP guru but setting safe m
ode 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 ar

this is caused by an attempt to allocate an amount of shared memory greater than your system can handle. The size it requests is base on the following formula, ring buffer size x image width x image height x 3 (for 24 bits images) + a bit of overhead. So
i
f for instance you were using 24bit 640x480 then this would come to about 92Mb if you are using the default buffer size of 100. If this is too large then you can either reduce the image or buffer sizes or increase the maximum amount of shared memory avail
able. 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-Manual/admin_user/kernel-resources.html

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 }{\insrsid15225841 system }{\insrsid7562726 commands to check and remove it if necessary.
If you get odd javascript errors and your web console or other screens come up with bits missing then it's possible that there is a problem with the PHP configuration. Sin
ce 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 inf
ormation about this directive can be seen at the following location, }{\cs16\ul\cf2\insrsid7562726 http://www.php.{\*\bkmkstart _Hlt42867874}n{\*\bkmkend _Hlt42867874}et/manual/en/configuration.directives.php#ini.short-open-tag}{\insrsid7562726
. However although by default most PHP installations support this form, some will need t
o have it switched on explicitly. To do this you will first need to find your php.ini file (do a 'locate php.ini' or 'find / -name php.ini'. Be aware however that sometimes you might find more than one, so ensure you identify the one that is actually bein
g used. You will then need to find the line that starts 'short_open_tag = ' and change the Off value to On. This }{\insrsid12872856 will}{\insrsid7562726
correct the problem. However in some cases you may have explicitly switched it off, so that XML compliant documents can be more easily serv
ed, or you may even not have permission to edit the file. In this case you can go into the web directory of ZoneMinder and run 'sh retag.sh' which will replace all the short open tags in the files themselves with the longer variant. You will obviously hav
e 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.
\rin0\lin720\itap0 {\insrsid7562726 Paths. I admit it, the various paths in ZoneMinder }{\insrsid15225841 can be}{\insrsid7562726 bit of a nightmare. Make sure that they are all correct and that permissions a

to fail. This is because the bandwidth available to cameras is limited by the fairly low USB speed. In order to use more than one USB camera with ZoneMinder (or any application) you will need to inform the driver that there are other cameras requiring ban
d
width. This is usually done with a simple module option. Examples are usb_alt=<n> for the OV511 driver and cams=<n> for CPIA etc. Check your driver documentation for more details. Be aware however that sharing cameras in this way on one bus will also limi
Incorrect libjpeg.a detection. It seems to be the case that in some cases the library file libjpeg.a is reported as missing even when apparently present. This appears to actually be down to the g++ compiler
not being installed on the host system. Since ZoneMinder contains both C++ and C files you need to be able to compile both of these file types and so usually need to ensure you have gcc and g++ installed (though they are often the same binary).

d zms memory leaks. It has been reported by some users with RedHat 9 that the zms process fails to terminate correctly when the controlled window is killed and also that it, and it\rquote

On other systems it may appear that zms is leaking and growing. However what grows is the total and shared memory size while the non-shared memory size stays constant. It's a little odd
but I think what it happening is that as zms picks images out of the shared memory ring buffer to display, as each slot is read the size of that bit of memory is added to the shared memory total for the process. As streamed images are not read consecutive
l
y it's a semi-random process so initially most of the buffer slots are new and the shared memory size grows then as time goes on the remaining unaccessed slots reduce until once all have been read the shared memory use caps out at the same size as the act
u
al segment. This is what I would have expected it to be in the first place, but it seems to do it incrementally. Then once this total is hit it grows no further. As it's shared memory anyway and already in use this apparent leak is not consuming any more

\insrsid11761538 formats are now pretty much }{\insrsid4947917 handled at almost the same speed as native RGB }{\insrsid11761538 formats. As this is what the capture d
aemons 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 ce
r
tain values. The other two main areas of optimisation are in the Blend and Delta image functions. Normally when doing motion detection the analysis daemons spend about 99% of their time comparing a captured image with the reference image and then blending
the two ready for the next capture. Both of these functions have been significantly improved. In previous versions there were two options for calculating image deltas (or differences), a simple RGB average and a Y channel calculation. Historically the RGB
one was faster however with the optimisations the Y channel calculation (which is more accurate) is now 15-20% faster and so has become the default though you can select either method by the }{\insrsid11761538\charrsid11761538 ZM_Y_IMAGE_DELTAS}{

to the image 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 }{

in tuning the zones to provide optimal motion detection.
Images Renamed. The capture and analysis images recorded during an event have been renamed from capture-???.jpg to ???-capture, and from analyse-???.jpg to ???-analyse.jpg. This is to allow all images (including diagnostic ones) to be associated with the
frame sequence number more easily. This means that old events will no longer be able to be viewed as the wrong image will be being searched for. To avoid this you can use the new \lquote zmupdate.pl\rquote utility to rename all your old images by doing

Again in .14 a problem occurred for a new release whereby zmconfig wanted to know the database details and but also previously wanted to access the database before it had asked the questions. This has now been addressed though it does require that zmconfi
g is run twice initially, once to created the scripts and once to import the configuration into the database.
In association with the previous error, the zm_config_defines.h file was not created in the absence of the database as this was what was used to assign configuration ids. This now takes place regardless of the database.

New contrast/brightness etc adjustments feature. This accessible from the Settings link on the monitor window. It's fairly basic at present but should work for most types of cameras. If you have any device or driver specific auto-brightness, auto-contrast
etc enabled the changes you make may appear to work but may be overridden by the auto feature immediately so check for that if your changes do not appear to be having an effect. Also if you have a number of cameras being multiplexed onto one device then a
ny changes here will probably affect all your cameras.
Added user and access control. If enabled in config (ZM_OPT_USE_AUTH) then you will need to define and login as ZM users. There will be one users already de
fined, with username 'admin' and password 'admin'. This user is defined will full permissions and clicking on the 'Options' link from the main console window will allow you to modify and create users with various permission sets which hopefully will satis
f
y most requirements. These users (except any defined with 'system' edit capability) can be restricted to certain cameras by adding the monitor ids as a comma-separated list (no spaces) to the appropriate field. Users limited to specific monitors may not c
reate or delete monitors even if defined with monitor edit permissions.
Some windows now (optionally) use a JavaScript timeout to refresh themselves rather than a refresh header. Since refresh headers were interrupted if a link of the page was linked ther
e were previously various forced refreshes from child windows to restart the refresh process. By using JS refresh timers which are not interrupted these extraneous refreshes have been mostly eliminated.

t more intelligent. On the suggestion of a couple of people I have made the zmdc.pl server spawning and waiting a bit more intelligent. Rather than waiting a fixed (short) amount of time, it now polls every second for a while, stopping if the connection i
s made. Thanks to Todd McAnally for the initial suggestion.
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. Th
is is to enable you to quickly see what the event was about without having to watch the stream or view all the static images.

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 fram
es it contains. Previously it did not take account of the pre and post event frames and so passed a much shorter value to the mpeg encoder than it should. This will only have affected short events encoded with ffmpeg but will have resulted in much faster
frame rates than necessary. This has now been corrected to take the whole event length into account.

may have been left out for filters that had no time component. The script has now been updated to reflect Ernst\rquote s suggested changes.

The MPEG/video area of the web GUI had been a bit neglected and looked somewhat ugly. This has now been improved to a degree and looks a bit nicer.
Historically ZoneMinder has only supported the Berkeley mpeg encoder which was slow and rather limited. ZoneMinder now supports the ffmpeg encoder as well which is much much faster and makes generation of MPEG vi
deos at realistic frame rates more of a reality. As ffmpeg has so many options and everyone will probably want a different emphasis you can now also specify additional ffmpeg options via zmconfig.pl.

ptured greyscale images were stored as JPEG files with a corresponding greyscale colourspace. This saved a small amount of space but meant that mpeg_encode had to do a conversion to encode them, and ffmpeg just fell in a heap. Now you can optionally opt t

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 yo
Previously ZoneMinder used quite a loose method for calculating the differences between two colour images. This was basically averaging the differences between each of the RGB components to get an overa
ll difference. This is still the default but by setting ZM_FAST_RGB_DIFFS to 'no' you can now make it calculate the Y (or brightness value) of the pixels and use the difference between those instead. This will be more accurate and responsive to changes bu
t
is may be slower especially on old machines. There is a slight double whammy here if you have a YUV palette for capture and set this option off as the image will be converted to RGB and then partially converted back to get the Y value. This is currently
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.

suspend alarm option - Added new -n option to zmu to effectively suspend alarm detection for a monitor. This is intended for short term use and to support PTZ cameras where alarm detection is desired to be suspended while the camera changes orientation or
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 th
e capture rate on one camera allows the spare FPS to be allocated to other devices. For instance with two cameras and no throttle, I get about 4FPS each. Throttling one to 2FPS allows the other to operate at 6FPS so you can allocate your capture resources
accordingly. This limiting can be disabled while alarms are occurring as a global option in zmconfig.pl.

Frame and event lengths fractional - A new field has been added to the Frames table. This is 'Delta' and is a fractional number of seconds relative to the event start time. This is inte

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 {\insrsid7562726 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.

to it soon though honest! You're lucky to even get this document.
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\insrsid7562726 \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\insrsid7562726 \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.
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.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033\insrsid7562726 \hich\af2\dbch\af0\loch\f2 o\tab}Automatic device configuration - Video 4 Linux
supports various device queries, it should be possible to get most of the device capability information from the device itself. The zmu utility does this now but it's not yet integrated into the web pages.
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033\insrsid7562726 \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.

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.

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.
