\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 A while back my garage was burgled and all my power tools were stolen! I realised shortly after that if I'd just had a camera overlooking the door then at least
I'd have know exactly when and who did the dirty deed. And so ZoneMinder was born. It's still relatively new but hopefully it has developed to be something that can be genuinely useful and prevent similar incidents or even perhaps bring some perpetrators
ZoneMinder is designed around a series of independent components that only function when necessary limiting any wasted resource and maximising the efficiency of your machine. A fairly ancient Pentium II PC should be able to track one camera per
device at up to 25 frames per second with this dropping by half approximately for each additional camera on the same device. Additional cameras on other devices do not interact so can maintain this frame rate. Even monitoring several cameras still will n
ot overload the CPU as frame processing is designed to synchronise with capture and not stall it.
\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 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 wi
th 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 }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 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 ca
n 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 th
at you don't wish to track or define areas that will alarm if various thresholds are exceeded in conjunction with other zones.

\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 Firstly, it uses MySQL so you'll need that. In order to compile you need to make sure you have a development instal
lation 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 }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 Next it does things wit
h JPEGs so you'll need at least libjpeg.a which I think come as standard nowadays with most distributions. Users have reported varying degrees of success with other jpeg libraries such as jpeg-mmx but these are not officially supported. If you plan to use
network cameras then the Perl Compatible Regular Expression library (libpcre.a) can prove useful but is not always essential. ZoneMinder also uses the netpbm utilities in a very limited way to generate thumbnails under certain circumstances though this ca
ZoneMinder can generate MPEG videos if necessary, for this you'll need either ffmpeg (recommended) or the Berkeley MPEG encoder (mpeg_encode). If you don't have either, don't worry, as the options will be hidden and you'll not really miss too
much. Some of the authentication uses openssl MD5 functions, if you get a grumble about these during configuration all it will mean is that authentication won\rquote
t be used for streaming. The web interface uses PHP and so you need that in your apache or other
web server as well, make sure MySQL support is available either statically or as a module. There are also various perl modules that you may need that vary depending on which options you choose on installation, for more details see later in this document.
Finally, there is quite a bit of image streaming in the package. So if you don't have FireFox or another browser that supports image streaming natively I recommend you get the excellent Cambozola java applet from }{
which will let you view the image stream in Internet Explorer and others. Otherwise you're limited to just refreshing still images or mpeg based streams, if you have compatible plugins.
\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 Hardware-wise, ZoneMinder has been used with various video and USB c
ameras with the V4L interface. It will also work with most Network or IP cameras. I don't have a lot of cameras myself so I've not had change to test it with a huge range personally however there is a list of devices that are definitely known to work on t
h
e web site. Please let me know if your camera works and is not listed. You do need to have Video4Linux installed. I've not got too many machines so I've only really used it on various RedHat/Fedora distributions, which seem to have everything there by def
ault 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.

ic application but is formed from several components. These components primarily include executable compiled binaries which do the main video processing work, perl scripts which usually perform helper and/or external inter
face tasks and php web scripts which are used for the web interface.
\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 A brief description of each of the principle components follows.
This is the ZoneMinder Capture daemon. This binary's job is to sit on a video device and suck frames off it as fast as possible, this should run at more or less constant speed.
This is the ZoneMinder Analysis daemon. This is the component that goes through the captured frames and checks them for motion which might generate an alarm or event. It generally keeps up
with the Capture daemon but if very busy may skip some frames to prevent it falling behind.
This is the ZoneMinder Frame daemon. This is an optional daemon that can run in concert with the Analysis daemon and whose function it is to actually write ca
ptured 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 t running or dies then the Analysis daemon just writes them itself.
web interface connects with this to get real-time or historical streamed images. It runs only when a live monitor stream or event stream is actually being viewed and dies when the event finishes or the associate web page is closed. If you find you have s
e
veral zms processes running when nothing is being viewed then it is likely you need a patch for apache (see the Troubleshooting section). A non-parsed header version of zms, called nph-zms, is also installed and may be used instead depending on your web s
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 nec
This is a small binary that exists only to ensure that the video device files can be read by the main capture daemons. It is often the case that these device files are set to be accessible by root on
ly on boot. This binary runs setuid and ensures that they have appropriate permissions. This is not a daemon and runs only on system start and then exits.
\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 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.
This is the ZoneMinder Daemon Control script. This is used by the web interface and the zmpkg.pl script to control and maintain the execution of the capture and analysis daemons, amongst others. You should not need to run this script yourself.
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 scrip
t 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 line. It can be run interactively or in batch mode either from the command line or a cron job or similar. In the zmconfig.pl there is an option to specify fast event deletes w
here the web interface only deletes the event entry from the database itself. If this is set then it is this script that tidies up the rest.
This is a simple script purely designed to keep an eye on the capture daemons and restart them if they lockup. It has been known for sync problems in the video drivers to cause this so this script makes sure that nothing important gets missed.
Currently this script is responsible for checking whether a new version of ZoneMinder is available and other miscellaneous actions related to upgrades and migrations. It is also intended to be a \lquote one stop shop\rquote

interface to generate video files in various formats in a common way. You can also use it from the command line in certain circumstances but this is not usually necessary.
This is an optional script that can be used to initiate and monitor X10
Home Automation style events and interface with an alarm system either by the generation of X10 signals on ZoneMinder events or by initiating ZoneMinder monitoring and capture on receipt of X10 signals from elsewhere, for instance the triggering of an X10
PIR. For example I have several cameras that don\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.

These are a set of example scripts which can be used to control Pan/Tilt/Zoom class cameras. Each script converts a set of standard parameters used for camera control into the actual protocol comman

maximum capture rate to a specified value. This may allow you to have more cameras supported on your system by reducing the CPU load or to allocate video bandwidth unevenly between cameras sharing the same video device. This value is only a rough guide a

way. An image will effectively vanish around 25 images later than when it was added. This blend value is what is specified here and if higher will make slower progressing events less detectable as the reference image would change more quickly. Similarly

n also just use \lquote cron\rquote jobs or other mechanisms to actually control the camera and keep them completely outside of the ZoneMinder settings. The zmtrigger.pl script is also available to implement custom external triggering.
Enter the full path to the device file that your camera is attached to, e.g. /dev/video0. Some video devices, e.g. BTTV cards support multiple cameras on one device so in this case enter the channel number in the Channel box or leave it at
zero if you're using a USB camera or one with just one channel.
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.
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 versio
n but for now if you have the choice choose one of grey or 24 bit colour.
The dimensions of the video stream your camera will supply. If your camera supports several just enter the one you'll want to use for this application, you can
always change it later. However I would recommend starting with no larger than 320x240 or 352x288 and then perhaps increasing and seeing how performance is affected. This size should be adequate in most cases. Some cameras are quite choosy about the sizes
you can use here so unusual sizes such as 197x333 should be avoided initially.
If your camera is mounted upside down or at right angles you can use this field to specify a rotation that is applied to the image as it is captured. This incurs a
n additional processing overhead so if possible it is better to mount your camera the right way round if you can. If you choose one of the rotation options remember to switch the height and width fields so that they apply, e.g. if your camera captures at
352x288 and you choose \lquote Rotate Right\rquote here then set the height to be 352 and width to be 288. You can also choose to \lquote flip\rquote the image if your camera provides mirrored input.

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 sid
e of the image and a Y value of 0 will place it at the top of the image. To place the timestamp at the bottom of the image use a value eight less than the image height.
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 like with a couple of provisos, (see next options). How
ever it is stored in shared memory and making it too large especially for large images with a high colour depth can use a lot of memory. A value of no more than 50 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.
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, t
oo 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 you started but if you get a lot of short events and would prefer them to run together to form fewer longer ones then increase the Pos
t
Event buffer size. The pre-event buffer is a true buffer and should not really exceed half the ring buffer size. However the post-event buffer is just a count that is applied to captured frames and so can be managed more flexibly. You should also bear in
mind the frame rate of the camera when choosing these values. For instance a network camera capturing at 1FPS will give you 10 seconds before and after each event if you chose 10 here. This may well be too much and pad out events more than necessary. Howe
ver 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.

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.

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. T
his might be for example to cover an area of the image like a plant or tree which moves a lot and which would trigger lots of alarms. Perhaps this is behind an area you'd like to monitor though, in this case you'd create an active zone covering the non-mo
v
ing parts and an inclusive zone covering the tree perhaps with less sensitive detection settings also. If something triggered an alarm in the Active zone and also in the Inclusive zone they would both be registered and the resulting alarm would be that mu
ch bigger than if you had blanked it out altogether.
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 a
ea I can ensure that a hedgehog alarm will only trigger if there is activity in that small area. If something much bigger occurs, like someone walking by it will trigger a regular alarm and not one from the Exclusive zone. Thus I can ensure I get alarms f
or big events and also special small events but not the noise in between.
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 mot
ion 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 ma
y
be achieved by limiting the maximum number of alarm pixels or other measure in an Active zone. However in some cases that zone may cover an area where the area of variable illumination occurs in different places as the sun and/or shadows move and it thus
may be difficult to come up with general values. Additionally, if the sun comes out rapidly then although the initial change may be ignored in this way as the reference image catches up an alarm may ultimately be triggered as the image becomes less differ
nt. Using one or more Preclusive zones offers a different approach. Preclusive zones are designed to be fairly small, even just a few pixels across, with quite low alarm thresholds. They should be situated in areas of the image that are less likely to hav
e
motion occur such as high on a wall or in a corner. Should a general illumination change occur they would be triggered at least as early as any Active zones and prevent any other zones from generating an alarm. Obviously careful placement is required to
ensure that they do not cancel any genuine alarms or that they are not so close together that any motion just hops from one Preclusive zone to another. As always, the best way is to experiment a little and see what works for you.

type is the opposite of Active. In this zone type no alarms will ever be reported. You can create an Inactive zone to cover any areas in which nothing notable will ever happen or where you get constant false alarms that don't relate to what you are trying
to monitor. An Inactive zone can overlay other zone types and will be processed first.
It was mentioned above that Inactive zones may be overlaid on other zones to blank out areas however as a general principle you should try and make zones abut each other
as much as possible and not overlap. This helps avoid repeated duplicate processing of the same area. For instance an Inclusive zone overlaying an Active zone when all other settings are the same will always trigger when the Active zone does which somewh
at 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.

eral other functions to the data to improve its ability to distinguish interesting signals from uninteresting noise. The first of these is a filter that removes any pixels that do not participate in a contiguous block of pixels above a certain size. These
options are always expressed in pixels and should be fairly small, and an odd number, three or five is a good value to choose initially. Application of this filter removes any tiny or discontinuous pixels that don't form part of a discrete block.

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 you

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.
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 divide
d 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 lik
ely to be much less than 100 but it does give a simple indication of how major the event was.
If you have defined your system as having controllable monitors and you are looking at a monitor that is configured for control, then clicking on the \lquote Control\rquote
link along the top of the window will change the short event listing area to a control area. The capabilities you have defined earlier determine exactly what is displayed in this window. Generally you will have a Pan/Tilt control area alo
ng with one or subsidiary areas such as zoom or focus control to the side. If you have preset support then these will be near the bottom of the window. The normal method of controlling the monitor is by clicking on the appropriate graphics which then send
a command via the control script to the camera itself. This may sometimes take a noticeable delay before the camera responds.
\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 It is usually the case that the control arrows are sensitive to where you click on them. If you have a camera that allows differen
t speeds to be used for panning or zooming etc then clicking near the point of the arrow will invoke the faster speed whilst clicking near the base of the arrow will be slower. If you have defined continuous motion then ongoing activities can be stopped b
y clicking on the area between the arrows, which will either be a graphic in the case of pan/tilt controls or a word in the case }{\insrsid4615107 of zoom and focus controls etc.

itself when used in browsers which support streamed images directly. Used in this way you can just click on the area of the image that interests you and the camera will centre on that spot. You can also use direct image control for relative motion when t
h
e area of the image you click on defines the direction and the distance away from the centre of the image determines the speed. As it is not always very easy to estimate direction near the centre of the image, the active area does not start until a short
distance away from the centre, resulting in a \lquote dead\rquote zone in the middle of the image.
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 tot
al 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 contain

a list of events selected according to a filter which will also pop up in its own window. Thus if you clicked on a 'day' total the filter will indicate that this is the period for which events are being filtered. The event listing window contains a simil
a

window will not refresh automatically, rather only on request. Other than that, you can choose to view events here or delete them as before.

ponding 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

except perhaps for 'Archived' which you can use to include or exclude Archived events. In general you'll probably do most filtering on un-archived events. There are also two elements, Disk Blocks and Disk Percent which don\rquote t

command. They relate to the amount of disk spac
e used and not the amount left free. Once your filter is specified, clicking 'submit' will filter the events according to your specification. As the disk based elements are not event related directly if you create a filter and include the term \lquote
DiskPercent > 95\rquote
then if your current disk usage is over that amount when you submit the filter then all events will be listed whereas if it is less then none at all will. As such the disk related terms will tend to be used mostly for automatic filters (see below).

t should be readable and executable by your web server user. It will get run once per event and the relative path to the directory containing the event in question. Normally this will be of the form <MonitorName>/<EventId> so from this path you can derive
both the monitor name and event id and perform any action you wish. Note that arbitrary commands are not allowed to be specified in the filter, for security the only thing it may contain is the full path to an executable. What that contains is entirely up
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 filter
s, so for instance events that happen during weekdays or at certain times of the day are highlighted, uploaded or deleted. Additionally using disk related terms in your filters means you can automatically create filters that delete the oldest events when
our disk gets full. Be warned however that if you use this strategy then you should limit the returned results to the amount of events you want deleted in each pass until the disk usage is at an acceptable level. If you do not do this then the first pass
w
hen the disk usage is high will match, and then delete, all events unless you have used other criteria inside of limits. ZoneMinder ships with a sample filter already installed, though disabled. The PurgeWhenFull filter can be used to delete the oldest ev
ents when your disk starts filling up. To use it you should select and load it in the filter interface, modify it to your requirements, and then save it making you sure you check the \lquote Delete Matching Events\rquote
option. This will then run in the background and ensure that your disk does not fill up with events.
From the monitor or filtered events listing you can now click on an event to view it in more detail. If you have streaming capability you will see a series of images that make up the event.
Under that you should also see a progress bar. Depending on your configuration this will either be static or will be filled in to indicate how far through the event you are. By default this functionality is turned off for low bandwidth settings as the im
age delivery tends to not be able to keep up with real-time and the progress bar cannot take this into account. Regardless of whether the progress bar updates, you can click on it to navigate to particular points in the events.
\par You will also see a link to a
llow you to view the still images themselves. If you don't have streaming then you will be taken directly to this page. The images themselves are thumbnail size and depending on the configuration and bandwidth you have chosen will either be the full image
s
scaled in your browser of actual scaled images. If it is the latter, if you have low bandwidth for example, it may take a few seconds to generate the images. If thumbnail images are required to be generated, they will be kept and not re-generated in futu
re. Once the images appear you can mouse over them to get the image sequence number and the image score.

colour defined for that zone and lets you see what it was that caused the alarm. Clicking on one of the thumbnails will take you to a full size window where you can see the image in all its detail and scroll through the various images that make up the eve

b
ase 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 (i
f supported) and generating an MPEG video of the event (if supported).
These last two options require further explanation. Archiving an event means that it is kept to one side and not displayed in the normal event listings unless you specifically ask to vie
w the archived events. This is useful for keeping events that you think may be important or just wish to protect. Once an event is archived it can be deleted or unarchived but you cannot accidentally delete it when viewing normal unarchived events.
\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 The fin
al option of generating an MPEG video is still somewhat experimental and its usefulness may vary. It uses the open source ffmpeg encoder to generate short videos, which will be downloaded to your browsing machine or viewed in place. When using the ffmpeg
ncoder, ZoneMinder will attempt to match the duration of the video with the duration of the event. Ffmpeg has a particularly rich set of options and you can specify during configuration which additional options you may wish to include to suit your prefere
n
ces. In particular you may need to specify additional, or different, options if you are creating videos of events with particularly slow frame rates as some codecs only support certain ranges of frame rates. Details of these options can be found in the do
cumentation for the encoders and is outside the scope of this document.
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 g
ood. However once a video has been created for an event it will be kept so subsequent viewing will not incur the generation overhead. Videos can also be included in notification emails, however care should be taken when using this option as for many frequ
ent events the penalty in CPU and disk space can quickly mount up.
The final area covered 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.

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

or loss.

tab allows you to specify the default language for your installation of ZoneMinder. Versions 1.17.0 and later support multiple languages but rely on users to assist in creating language files for sp

ntrol and capability elements of ZoneMinder are not intended to be able to support every camera out of the box. Some degree of development is likely to be required for many cameras. This should often be a relatively straightforward task however if you hav
e
a camera that you want to be supported then please feel free to get in touch and I should be able to provide an estimate for how much effort this is likely to be. It is also the case that I have only been able to access this limited number of cameras to
test against; some other cameras may use different motion paradigms that don\rquote
t fit into the control capability/script architecture that ZoneMinder uses. If you come across any cameras like this then please forward as much information to me as possible so that I may be able to extend the ZoneMinder model to encompass them.
If you have a camera that supports PTZ controls and wish to use it with ZoneMinder then the first thing you need to do is ensure that it has an accurate entry in the ca
pabilities table. To do this you need to go to the Control tab of the Monitor configuration dialog and select \lquote Edit\rquote
where it is listed by the Control Type selection box. This will bring up a new window which lists, with a brief summary, the existing capab
ilities. To edit an existing capability to modify select the Id or Name of the capability in question, or click on the Add button to add a new control capability. Either of these approaches will create a new window, in familiar style, with tabs along the
top and forms fields below. In the case of the capabilities table there are a large number of settings and tabs, the mean and use of these are briefly explained below.
This is the full path to a script or application that will map the standard set of ZoneMinder control commands to equivalent control protocol command. This may be one of the shipped example zmcontrol-*.pl scripts or something else entirely.

The second key element to controlling cameras with ZoneMinder is ensuring that an appropriate control script or application is present. A small num
ber of sample scripts are included with ZoneMinder and can be used directly or as the basis for development. Control scripts are run atomically, that is to say that one requested action from the web interface results in one execution of the script and no
state information is maintained. If your protocol requires state information to be preserved then you should ensure that your scripts do this as ZoneMinder has no concept of the state of the camera in control terms.

hen you need to ensure that it supports the parameters that ZoneMinder will pass to it. If you already have scripts or applications that control your cameras, the ZoneMinder control script will just act as glue to convert the parameters passed into a form
that your existing application understands. If you are writing a script to support a new protocol then you will need to convert the parameters passed into the script to equivalent protocol commands. If you have carefully defined your control capabilities

If you wish to use the XHTML-MP interface to ZoneMinder there is no extra configuration required to enable it per se. However ZoneMinder needs to be able to figure out what kind of content to deliver to particular browsers, so you have two cho
ices. You can edit zm.php and include a definition that corresponds to your phone, describing a small number of basic capabilities, you will see a couple of examples already there, or you can use the comprehensive open source WURFL package available from
. You will need to download both the WURFL php files and the wurfl.xml file itself. WURFL is a resource containing information on the capabilities of a huge number of mobile phones,
devices and browsers. Thus once it has matched your phone it can determine various capabilities it may possess. This means that ZoneMinder itself only has to deal with these capabilities and not the individual phone types.
\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 To use WURFL you should install the php files in the same directory as ZoneMinder and then create a \lquote wurfl\rquote

st components of ZoneMinder can emit informational, warning, error and debug messages in a standard format. These messages can be logged in one or more locations. By default all messages produced by scripts are logged in <script name>.log files which are
placed in the directory defined by the ZM_PATH_LOGS configuration variable. This is initially defined as \lquote /tmp\rquote
though it can be overridden (see the Options and Users section above). So for example, the zmpkg.pl script will output messages to /tmp/zmpkg.pl, an example of these messages is
where the first part refers to the date and time of the entry, the next section is the name (or an abbreviated version) of the script, followed by the process id in
square brackets, a severity code (INF, WAR, ERR or DBG) and the debug text. If you change the location of the log directory, ensure it refers to an existing directory which the web user has permissions to write to. Also ensure that no logs are present in
that directory the web user does not have permission to open. This can happen if you run commands or scripts as the root user for testing at some point. If this occurs then subsequent non-privileged runs will fails due to being unable to open the log file
s.
\par As well as specific script logging above, information, warning and error messages are logged via the system syslog service. This is a standard component on Linux systems and allows logging of all sorts of messages in a standard way and using a standard f
ormat. On most systems, unless otherwise configured, messages produced by ZoneMinder will go to the /var/log/messages file. On some distributions they may end up in another file, but usually still in /var/log. Messages in this file are similar to those in
the script log files but differ slightly. For example the above event in the system log file looks like

A number of users have asked how to suppress or redirect ZoneMinder messages that are written to this file. This most often occurs due to not wanting other system messages to be overwhelmed and obscured by the ZoneMind
er produced ones (which can be quite frequent by default). In order to control syslog messages you need to locate and edit the syslog.conf file on your system. This will often be in the /etc directory. This file allows configuration of syslog so that cert
ain classes and categories of messages are routed to different files or highlighted to a console, or just ignored. Full details of the format of this file is outside the scope of this document (typing \lquote man syslog.conf\rquote
The syslog service uses the concept of priorities and facilities where the former refers to the importance of the message and the latter refers to that part of the system from which it originated. Standard priorities include \lquote info\rquote , \lquote
warning\rquote , \lquote err\rquote and \lquote debug\rquote and ZoneMinder uses these priorities when generating the corresponding class of message. Standard facilities include \lquote mail\rquote , \lquote cron\rquote and \lquote security\rquote

oduce error and debug messages. The way that the binaries work is slightly different. Binaries generate information, warning and error messages using syslog in exactly the same way as scripts and these messages will be handled identically. However debug o
u
tput is somewhat different. For the scripts, if you want to enable debug you will need to edit the script file itself and change the DBG_LEVEL constant to have a value of 1. This will then cause debug messages to be written to the <script>.log file as wel
l
as the more important messages. Debug messages however are not routed via syslog. Scripts currently only have one level of debug so this will cause any and all debug messages to be generated. Binaries work slightly differently and while you can edit the
call to zmDbgInit that is present in every binary\rquote s \lquote main\rquote function to update the initial value of the debug level, there are easier ways.

then go to the Debug tab. There you will find a number of debug options. The first thing you should do is ensure that the ZM_EXTRA_DEBUG setting is switched on. This enables debug generally. The next thing you need to do is select the debug target, level

\par }\pard \s16\qj \li0\ri0\sa180\nowidctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid475446 The first thing you need to do is check the ZoneMinder logs to see if you can find out what is and what isn\rquote t working. }{\insrsid5185469 See the }

nfiguration. 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> -q -v to get the settings. If you can't g
e
t them to work with that then the likelihood is they won't work with ZoneMinder. Also check the system logs (usually /var/log/messages) for any video configuration errors. If you get some and you're sure they're not a problem then switch off ZM_STRICT_VID
EO_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 <device>' (or whatever your video device is). If it returns immediately there
's a problem so check the logs, if it stays up then your video configuration is probably ok. To get more information out of it use debug as specified below. Also check that the shared memory segment has been created by doing 'ipcs -m'. Finally, beware of
doing tests as root and then trying to run as another user as some files may not be accessible. If you're checking things as root make sure that you clean up afterwards!

ur 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 w
e
b server, if it dies or is shut down then the daemons may disappear. In this version the daemons are run under the control of a script which should trap expected signals but it is possible this doesn't cover all circumstances. If everything else works but

t get images in your browser a likely cause is a mismatch between where your web server expects to execute CGI scripts and where you have installed the zms streaming server. Check your server configuration for the correct CGI location and ensure yo
u have supplied the same directory to the ZoneMinder configure script via the \endash with-cgidir option.
One of the more common errors you can see in the log files is of the form 'Can't shmget: Invalid argument'. Generally speaking this is caused by an attempt
to allocate an amount of shared memory greater than your system can handle. The size it requests is base on the following formula, ring buffer size x image width x image height x 3 (for 24 bits images) + a bit of overhead. So if for instance you were usin
g
24bit 640x480 then this would come to about 92Mb if you are using the default buffer size of 100. If this is too large then you can either reduce the image or buffer sizes or increase the maximum amount of shared memory available. If you are using RedHat
then you can get details on how to change these settings at }{\field\fldedit{\*\fldinst {\cs29\ul\cf2\insrsid475446\charrsid15794850 HYPERLINK "http://www.redhat.com/docs/manuals/database/RHDB-2.1-Manual/admin_user/kernel-resources.html" }{
You should be able to use a similar procedure with other distributions to modify the shared memory pool without kernel recompilations though in some cases this may be necessary. You can also sometimes get shared memory errors if you have changed the
monitor image size for instance. In this case it is sometimes that an old process is hanging onto the shared memory and will not let it be resized. Ensure that you do a full ZoneMinder restart and/or manually delete the shared memory segment to check. Us
e the ipcs and ipcrm system commands to check and remove segments 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. Since ver
sion 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 informati
on about this directive can be seen at the following location, }{\cs29\ul\cf2\insrsid475446\charrsid15794850 http://www.php.net/manual/en/configuration.directives.php#ini.short-open-tag}{\insrsid475446
. However although by default most PHP installations support this form, some will need to have it switched on explicit
ly. To do this you will first need to find your php.ini file (do a 'locate php.ini' or 'find / -name php.ini'. Be aware however that sometimes you might find more than one, so ensure you identify the one that is actually being used. You will then need to
ind the line that starts 'short_open_tag = ' and change the Off value to On. This will correct the problem. However in some cases you may have explicitly switched it off, so that XML compliant documents can be more easily served, or you may even not have
p
ermission to edit the file. In this case you can go into the web directory of ZoneMinder and run 'sh retag.sh' which will replace all the short open tags in the files themselves with the longer variant. You will obviously have to remember to do this for e
ach subsequent version of ZoneMinder that you install as well.
Paths. I admit it, the various paths in ZoneMinder can be bit of a nightmare mainly because some relate to real directories and others to web paths. Make sure that they are all }{\insrsid5185469 sensible and }{\insrsid475446 corr
ect and that permissions are such that the various parts of ZoneMinder can actually run.

Unsupported palettes. ZoneMinder currently is designed to use the simple palettes of greyscale and 24 bit as well as now the YUV420P and some other palettes. This should cove

ause 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 usua

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 o
n the host system. Since ZoneMinder contains both C++ and C files you need to be able to compile both of these file types and so usually need to ensure you have gcc and g++ installed (though they are often the same binary).

p
ening is that as zms picks images out of the shared memory ring buffer to display, as each slot is read the size of that bit of memory is added to the shared memory total for the process. As streamed images are not read consecutively it's a semi-random pr
cess so initially most of the buffer slots are new and the shared memory size grows then as time goes on the remaining unaccessed slots reduce until once all have been read the shared memory use caps out at the same size as the actual segment. This is wha

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 star

A custom title can now be added via the normal Options dialog (ZM_WEB_TITLE_PREFIX). This title will be used in all browser windows and allows you to distinguish between multiple ZM installations for example.
Ordinarily ZoneMinder will resize the console window to fit the number of monitors displayed. If you are using a tabbed browser this can be a little irritating. A new option (ZM_WEB_RESIZE_CONSOLE) has been added to control this behaviour.
Version 1.21.0 added support for events to be labelled with Cause and Notes fields. However these could not be modified directly from the web interface. This has been amended so that an \lquote Edit\rquote
link is now present in the events listing. Clicking on this allows you to modify these fields for one or more events so they can be identified as belonging to a particular incident.

Previously in the c/c++ code accessor functions had to be called to access the value of configuration options. This was expensive when done repeatedly so some classes used cached local variables to avoid this. The configuration has been

The zmaudit.pl script has been modified to be faster and access disk a lot less. Previously it was possible for this script to frequently thrash disks while determining timestamps on directories.

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

currently playing event). The timing of the replay is done depending on the calculated length of the event (plus one second) and so may not exactly correspond to the real event length. In particular this is unlikely to work if replaying events using MPEG

described above. Note that if an alarm is in progress single isolated alarmed frames will still prolong it and the count only applies to the initial frames that would cause the event.

All stills views now use the single image mode of zms rather than spawning off a zmu process to write an image which is then read. This reduces complexity of double buffering significantl

The generated MIME types when creating streamed video were previously assigned by zms depending on which of a limited number of output formats was specified

. Thus filters using these criteria will either match all events or none at all depending on the
disk usage at the time of filter execution. The addition of these terms along with the ability to sort and limit filter results now means it is possible to create a filter that will automatically clear out old events once disk usage exceeds a certain val
u
e. Included in the database schemas for both new installations and upgrades is a sample filter called PurgeWhenFull which can be used to do this. It is initially not set to do anything automatically so if you want to use it, you should load it into the fi

. Please note that filters created using disk related terms to delete events should always contain a limit term also otherwise it is possible for all events to match and
thus be deleted. Using a limit ensures that only a small number are affected at any one time.
Filters can now be defined to automatically execute an external script or program of your choosing. This can be specified when the filter is saved. Not
e that for security reasons this cannot be just any arbitrary command but must be readable and executable by your web server effective user. The script or program you specify here will be executed in the events root directory once for each event and will

then this will be parsed and images extracted from the stream. This is much faster than before and frame rates can be as fast now with network cameras as with capture cards and video. This feature also has the side-effect that one ZoneMinder installation
NPH Streaming. After months of frustration I have finally figured out why streams were corrupted using Cambozola versions after 0.22. It turned out that apache was injecting characters into the streams which was sc
rewing 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
a
lso 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 t
he false character injection seems to disappear so I suspect this is a better way to use zms.
Bulk Frame Records. With the recent advent of the 'Record' and 'Mocord' modes a lot of people have started using ZoneMinder as a pseudo-DVR. This meant that a lot
of database activity was taking place as each captured frame required its own entry in the database. The frames table has now been reorganised so that 'bulk' frames may be written at defined intervals to reduce this database activity. The records act as m
arkers and individual frame timings are interpolated in between. Bulk frames are only used when no alarm or motion detection activity is taking place and normal frame records are kept otherwise.

which the event was selected from. Thus if the list was sorted on ascending scores then the \lquote next\rquote
event is the one below which has a higher score etc. A possibly counterintuitive side effect of this is that as the default list is sorted by descending time the \lquote next\rquote
event is the one below in the list which will actually be earlier and the \lquote previous\rquote event is later. So long as you remember that next and prev refer to the order of the list you should be ok.

Optimisations and Performance Improvements. This release contains several major performance improvements in various areas. The first of these is that image processing for YUV style input formats are now pretty much handled
at almost the same speed as native RGB formats. As this is what the capture daemons spend most of their time doing, the improvement helps reduce the amount of CPU time by a significant degree. Application of these changes also highlighted a bug that had e
x
isted previously in YUV conversion which caused incorrect conversions for certain values. The other two main areas of optimisation are in the Blend and Delta image functions. Normally when doing motion detection the analysis daemons spend about 99% of the
i
r 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 differe
ces), 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 m
e
thod by the ZM_Y_IMAGE_DELTAS configuration option. A new method of image blending has also been added which is up to 6 times faster than the old one which is retained for compatibility and because in some unusual circumstances it may still be more accura
te (see the ZM_FAST_IMAGE_BLENDS option for details). Altogether these optimisations (along with other common sense ones such as not maintaining a reference image in \lquote Record\rquote
mode where it is not used) significantly reduce the CPU load for most systems, esp
ecially 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.

ever 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
Compact Montage. The traditional montage view includes individual small menus for each monitor and a status display. This results in a somewhat cluttered display and the refreshing of the status displays may generate more
accesses than desirable. Using the ZM_WEB_COMPACT_MONTAGE configuration option allows this montage view to only include the monitor streams and one overall menu bar with no status displays.

hange. Traditionally ZoneMinder has time-stamped each image as it is captured. This ensures that all images have their capture time recorded immediately. However there are several side-effects which may be undesirable. Firstly the time and resource is spe
n
t time-stamping images that are not recorded and which are discarded, secondly the timestamp is included in any motion detection and may potentially trigger an alarm if detection parameters are very sensitive. The third effect is that as the timestamp is
added to the image at it\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_TIMESTAM
P_ON_CAPTURE configuration option, to indicate whether the timestamps should be added on capture, as before, or only added when the image is viewed or recorded. Setting it to this later value allows timestamps to be added to scaled images. This is little

allow a double buffering approach. Thus a new image is loaded in the background and only written to screen when complete. This removes the refresh flicker that means that the screen blanks periodically however uses more JavaScript so may not be suitable f
or all platforms. Whether ZoneMinder uses double buffering or not is controlled by the ZM_WEB_DOUBLE_BUFFER configuration option.

mode could sometimes result in events a multiple of that length. So events that were meant to be 15 minutes long could sometimes be 30 or even 45 minutes. This was especially the case with monitors that had low frame rates. This is now fixed.
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.

eature is that of adding extra information to allow diagnostics of the process of image detection. This has previously been somewhat hit and miss but in this version a new configuration option ZM_RECORD_DIAG_IMAGES has been included to allow this. This op
ion 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 alar
m but those following it are included and should assist in tuning the zones to provide optimal motion detection.

nalyse-???.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 searche
d 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.

Stream Scaling Resizing. Previously when watching a stream and modifying the scale of the streamed feed only the actual feed would change size and the containing fra

You can then reselect that state later which basically involves resetting the monitors to have these saved functions and then doing a system restart.

ch just allows you to watch the feed, Modect (= old Active) which is MOtion DetECT and which will capture events as previously, Record which continuously records with no analysis and MoCord which is a hybrid of Modect and Record and which will continuousl
y
record but also do motion detection and highlight where this has occurred. The Record and Mocord functions both records events whose length in seconds is defined by the 'Section Length' monitor attribute. You can additionally specify a 'Frame Skip' value
to tell it to not record 'n' frames at a time, when not alarmed.
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 contro
lled outside of zmdc and zmpkg. Additionally the X10 triggers may now be specified in an X10 section. This has changed to allow for other types of triggers to be added more easily.

can list all of the events if you like by choosing the appropriate option. There are shortcuts to pages of events at the top of the listing. If these produce strange looking sequences like 1,2, 3, 5, 9, 17, 37 etc this is deliberate and uses an exponentia

Shared memory permissions. Following introduction of a user permissions system the previous 777 mode for shared memory was deemed insecure. Consequently from now on shared memory is only

Double first images. Fixed a problem where the first image of an event was being recorded twice. I don\rquote t think this was at the cost of any of the other images but one copy was an extra.
Made zmdc connect 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 eve
ry second for a while, stopping if the connection is 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 snap
shot of the event frame with the highest score. This is to enable you to quickly see what the event was about without having to watch the stream or view all the static images.

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

As well as the existing greyscale and 24 bit RGB palettes, you can now choose YUV420P and RGB565. Rewrote the palette/colours area a bit to enable support for other palettes in the future if requested. Bear in mind though that Y
UV palettes are converted into RGB internally so if you have the choice RGB24 may be faster as it's the 'native' format used within.

Historically ZoneMinder has only supported the Berkeley mpeg encoder which was slow and rather limited. ZoneMinder now supports the ffmpeg encoder as well which is much much faster and makes generation of MPEG videos at realistic
frame rates more of a reality. As ffmpeg has so many options and everyone will probably want a different emphasis you can now also specify additional ffmpeg options via zmconfig.pl.

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

Previously ZoneMinder used quite a loose method for calculating the differences between two colour images. This was basically averaging the differences between each of the RGB components to get an overall difference. This is
still the default but by setting ZM_FAST_RGB_DIFFS to 'no' you can now make it calculate the Y (or brightness value) of the pixels and use the difference between those instead. This will be more accurate and responsive to changes but is may be slower esp
e
cially on old machines. There is a slight double whammy here if you have a YUV palette for capture and set this option off as the image will be converted to RGB and then partially converted back to get the Y value. This is currently very inefficient and n
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.
