\par }\pard \s15\qj \li0\ri0\sa180\widctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid150409 A while back my garage was burgled and all my power tools were }{\insrsid14238447 stolen}{\insrsid150409
! 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 }{\insrsid8588488 relatively new}{\insrsid150409 but hopefully it }{
\insrsid8588488 has developed}{\insrsid150409 to be something that can be genuinely useful and prevent similar incidents or }{\insrsid8588488 even }{\insrsid150409 perhaps bring some perpetrators to justice.
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 d
evice at up to 25 frames per second with this dropping by half approximately for each additio}{\insrsid8588488 nal camera on the same device. A}{\insrsid150409
dditional 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 }\pard \s15\qj \li0\ri0\sa180\widctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid150409 As well as being fast ZoneMinder is designed to be friendly and even more than that, actually useful. As well as the fast video interface core it also comes with
a user friendly and comprehensive PHP based web interface allowing you to control and monitor your cameras from home or even at work or on the road. It supports variable web capabilities based on available bandwidth. The web interface also allows you to
iew 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 \s15\qj \li0\ri0\sa180\widctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid150409 The core of ZoneMinder is the capture and analysis of images and there is a highly configurable set of parameters that allow you to ensure that you can
eliminate false positives whilst ensuring that anything you don't want to miss will be captured and saved. ZoneMinder allows you to define a set of 'zones' for each camera of varying sensitivity and functionality. This allows you to eliminate regions that
you don't wish to track or define areas that will alarm if various thresholds are exceeded in conjunction with other zones.

\insrsid150409 ZoneMinder needs a couple of things to work}{\cf0\revised\revauth1\revdttm111218027\insrsid992481 . }{\deleted\revauthdel1\revdttmdel111218027\insrsid150409\delrsid992481 .}{\cf0\revised\revauth1\revdttm111218027\insrsid992481 Ordina
rily the \lquote configure\rquote script will check for the presence of required (and optional) components but it is useful to be prepared beforehand.
\par }{\insrsid150409 Firstly, it uses MySQL so you'll need that. In order to compile you need to make sure you have a development installa
tion 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 \s15\qj \li0\ri0\sa180\widctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid150409 Next it does things with JPEGs so you'll need at least libjpeg.a which I think come as standard nowadays with most distributions. }{\insrsid6106433
Users have reported varying degrees of success with other jpeg libraries such as jpeg-mmx but these are not officially supported. }{\insrsid6449428 If you plan to use ne
twork cameras then the Perl Compatible Regular Expression library (libpcre.a) can prove useful but is not always essential. ZoneMinder}{\insrsid150409
also uses the netpbm utilities in a very limited way to generate thumbnails under certain circumstances though this can be modified.
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 }{
\insrsid7103735 too }{\insrsid150409 much. }{\insrsid7103735 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. }{
\insrsid150409 The web interface uses PHP and so you need that in your apache or other w
eb 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.
\par }\pard \s15\qj \li0\ri0\sa180\widctlpar\nooverflow\faroman\rin0\lin0\itap0 {\insrsid150409 Finally, there is quite a bit of image streaming in the package. So if you don't have }{\deleted\revauthdel1\revdttmdel111218027\insrsid150409\delrsid992481
Netscape }{\cf0\revised\revauth1\revdttm111218027\insrsid992481 FireFox }{\insrsid150409 or another browser that supports image streaming natively I recommend you get the excellent Cambozola java applet from }{\cs16\ul\cf2\insrsid150409
http://www.charliemouse.com/code/cambozola/}{\insrsid150409 which will let you view the image stream in Internet Explorer and others. Otherwise you're limited to just refreshing still images}{\cf0\revised\revauth1\revdttm111218027\insrsid992481 or mpeg

It will also work with most Network or IP cameras. }{\insrsid150409 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 wor
k on the web site. Please let me know if your camera works and is not listed. You do need to have Video4Linux installed. I've not got too many machines so I've only really used it on various RedHat}{\insrsid7103735 /Fedora}{\insrsid150409
distributions, which seem to have everything there
by default I think. SlackWare does need a bit more tinkering than other distributions; there is a document on the web site describing what users have had to do to get it working. Please give me feedback on other distributions not listed on the site.
ZoneMinder is not a single monolithic application but is formed from several components. These components primarily include executable compiled binaries which do the main video processing work, perl scripts which usually perform helper and/or external
interface tasks and php web scripts which are used for the web interface.

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 kee

\insrsid14973247 'action' is 'on', 'off', 'cancel' or \lquote show\rquote where 'on' forces an alarm condition on, 'off' forces an alarm condition off and 'cancel' negates the previous 'on' or 'off'. The \lquote show\rquote
action merely updates some auxiliary text which can optionally be displayed in the images captured by the
monitor. Ordinarily you would use 'on' and 'cancel', 'off' would tend to be used to suppress motion based events. Additionally 'on' and 'off' can take an additional time offset, e.g. on+20 which automatically 'cancel's the previous action after that numbe
\insrsid14973247 'score' is the score given to the alarm, usually to indicate it's importance. For 'on' triggers it should be non-zero, otherwise it should be zero.

\insrsid14973247 \lquote showtext\rquote is up to 32 characters of text that can be displayed in the timestamp that is added to images. The \lquote show\rquote
action is designed to update this text without affecting alarms but the text is updated, if present, for any of the actions. This is designed to allow external input to appear on the images captured, for instance temperature or personnel identity etc.
Note that multiple messages can be sent at once and should be LF or CRLF delimited. Without customisation zmtrigger.pl is of little use, but if you configure it correctly it can help in
tegrate other systems to generate external triggers that will cause ZoneMinder events.
These are a set of example scripts which can be used to control Pan/Tilt/Zoom class cameras. Each script converts a set of standard parameters used for
camera control into the actual protocol commands sent to the camera. If you are using a camera control protocol that is not in the shipped list then you will have to create a similar script though it can be created entirely separately from ZoneMinder and

This script is used to manage the experimental motion tracking feature. It is responsible for detecting that an alarm is taking place and moving the camera to point to the alarmed location, and then subsequently returning it to a defined st

it will remember your answers from}{\insrsid15812926 beforehand}{\insrsid150409 . If you just want to rerun the substitutions you can run zmconfig.pl in non-interactive mode by typing

the facility in xawtv, or other tool, to capture either one or more still images or possibly a movie. If this works and the images or movie are not garbage then the chances are that ZoneMinder will work fine also.

This relates to the timestamp that is applied to each frame. It is a \lquote s}{\insrsid7282709 trftime}{\insrsid150409 \rquote style string. It is actually passed through }{\insrsid7282709 strftime}{\insrsid150409

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 t

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). 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 }{\insrsid16398105 50 }{\insrsid150409
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 o
n 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.

emon 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.
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 a
nd subsequent to the event. A value of 10 for both of these will get you started but if you get a lot of short events and would prefer them to run together to form fewer longer ones then increase the Post Event buffer size. The pre-event buffer is a true
b
uffer 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 the
s
e values. For instance a network camera capturing at 1FPS will give you 10 seconds before and after each event if you chose 10 here. This may well be too much and pad out events more than necessary. However a fast video card may capture at 25FPS and you w
ill want to ensure that this setting enables you to view a reasonable time frame pre and post event.
This option allows you to specify how many consecutive alarm frames must occur before an alarm event is generated. The usual, and defaul
t, value is 1 which implies that any alarm frame will cause or participate in an event. You can enter any value up to 16 here to eliminate bogus events caused perhaps by screen flickers or other transients. Values over 3 or 4 are unlikely to be useful how
ever. Please note that }{\insrsid342179 if you have statistics recording enabled then currently statistics are not recorded for the first \lquote Alarm Frame Count\rquote

apable of high capture rates but find that you generally do not require this performance at all times and would prefer to lighten the load on your server. This option permits you to limit the maximum capture rate to a specified value. This may allow you t
o
have more cameras supported on your system by reducing the CPU load or to allocate video bandwidth unevenly between cameras sharing the same video device. This value is only a rough guide and the lower the value you set the less close the actual FPS may
approach it especially on shared devices where it can be difficult to synchronise two or more different capture rates precisely. There is a global configuration option that allows you to turn this limiting off in the event of an alarm.

Each analysed image in ZoneMinder is a composite of previous images and is formed by applying the current image as a certain percentage of the previous reference image. Thus, if we entered the value of 10 here, each image\rquote
s part in the reference image will diminish by a factor of 0.9 each time round. So a typical reference image will be 10% the previous image, 9% the one before that and then 8.1%, 7.2%, 6.5% and so on of the rest
of the way. An image will effectively vanish around 25 images later than when it was added. This blend value is what is specified here and if higher will make slower progressing events less detectable as the reference image would change more quickly. Simi

arly 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 requiremen
ts what the appropriate value would be for you but start with 10 here and adjust it (usually down) later if necessary.

the whole image and will be red. Beneath that will be a table containing a listing of your zones. Clicking on either the relevant bit of the image or on the Id or Name in the table will bring up another window where you can edit the particulars for your Z
ones. As you can see there are quite a few, so now is a good time to go through them. The options are as follows.
This is just a label to identify the zone by. You can change this to be more representative if you like, though it isn't used much except for logging and debugging.

l 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 lot and which would trigger lots of alarms. Perhaps this is behind an area you'd like to monitor though, in this case you'd create an active zone covering the non-moving parts an
d
an inclusive zone covering the tree perhaps with less sensitive detection settings also. If something triggered an alarm in the Active zone and also in the Inclusive zone they would both be registered and the resulting alarm would be that much bigger tha
: The next zone Type is Exclusive. This means that alarms will only be triggered in this zone if no alarms have already been triggered in Active zones. This is the most specialised of the zone types and you
may never use it but in its place it is very useful. For instance in the camera covering my garden I keep watch for a hedgehog that visits most nights and scoffs the food out of my cats bowls. By creating a sensitive Exclusive zone in that area I can ensu
e that a hedgehog alarm will only trigger if there is activity in that small area. If something much bigger occurs, like someone walking by it will trigger a regular alarm and not one from the Exclusive zone. Thus I can ensure I get alarms for big events
and also special small events but not the noise in between.
: This zone type is relatively recent. It is called a Preclusive zone because if it is triggered it actually precludes an alarm being generated for that image frame. So motion or other c
hanges that occur in a Preclusive zone will have the effect of ensuring that no alarm occurs at all. The application for this zone type is primarily as a shortcut for detecting general large-scale lighting or other changes. Generally this may be achieved
b
y 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 diffic
u
lt to come up with general values. Additionally, if the sun comes out rapidly then although the initial change may be ignored in this way as the reference image catches up an alarm may ultimately be triggered as the image becomes less different. Using one
or more Preclusive zones offers a different approach. Preclusive zones are designed to be fairly small, even just a few pixels across, with quite low alarm thresholds. They should be situated in areas of the image that are less likely to have motion occur
such as high on a wall or in a corner. Should a general illumination change occur they would be triggered at least as early as any Active zones and prevent any other zones from generating an alarm. Obviously careful placement is required to ensure that th
ey 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.

posite 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. A
n Inactive zone can overlay other zone types and will be processed first.
I mentioned above that Inactive zones may be overlaid on other zones to blank out areas however as a general principle you should try and make zones abut each other as much as possibl
e and do not overlap. This helps avoid repeated duplicate processing of the same area. For instance an Inclusive zone overlaying an Active zone when all other settings are the same will always trigger when the Active zone does which somewhat defeats the o
bject 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.

Percent\rquote refers to a percentage area of the zone itself}{\insrsid150409 . In general \lquote Pixels\rquote is more precise whereas percentages are easier to use to start with or if you change image sizes fre

whereas it now only refers to the area of the zone. This makes trying to work out necessary sizes rather easier.

This is a new addition to Zone definitions. It allows you to specify the nature of the alarm checking that will take place, and more specifically what tests are applied to determine whether a frame represents an alarm or not. The three options are
\lquote AlarmPixels\rquote , \lquote FilteredPixels\rquote and \lquote Blobs\rquote
and depending on which option is chosen some of the following other settings may become unavailable. The first of these indicates that only a count of individual alarmed pixels should be used to dete
rmine the state of a image, the second indicate that the pixels should be filtered to remove isolated pixels (see below) before being counted, and the third uses a more sophisticated analysis which is designed to aggregate alarmed pixels into continuous g
roups, or \lquote blobs\rquote
. Blob analysis is the method ZoneMinder has always used previously (before it became optional) and so this is the default. However this method takes slightly longer and so if you find that one of the other methods works just as well for yo
u and you wish to maximise performance you can opt for that instead. Some of the more useful alarm related features such as highlighted analysis images are only available with the \lquote Blob\rquote setting.

ore sophisticated integer algorithm to calculate a Y (or brightness) value from the colours themselves.
- The following two settings define the minimum and maximum number of pixels that exceed this threshold that would cause an alar
m. 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 m
a
ximum must not be exceeded or the alarm will be cancelled. This is to allow for sudden changes such as lights coming on etc, which you may wish to disregard. In general a value of zero for any of these settings causes that value to be ignored, so you can
safely set a maximum to zero and it will not be used. The use of just a number of pixels is however a very brute force method of detection as many small events dispersed widely are not distinguished from a compact one.
tion of valid event ZoneMinder applies several other functions to the data to improve its ability to distinguish interesting signals from uninteresting noise. The first of these is a filter that removes any pixels that do not participate in a contiguous b

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 sens

ncoder or the faster and new ffmpeg encoder. Either of these will generate a short video, which will be downloaded to your browsing machine to view. Due to the relatively slow frame rate that ZoneMinder will capture at and the high minimum frame rate that
the Berkeley encoder uses videos created by this method will be very quick. However when using the ffmpeg encoder, ZoneMinder will attempt to match the duration of the video with the duration of the event. This has the useful effect of making the video wa

chable 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 in

.}{\cs35\cf1\insrsid4094536 A small number of example capabilities are included in ZoneMinder, these can be used \lquote as is\rquote or modified.

te motion requests from the web interface into a standard set of commands which are passed to a script defined in the control capability. Example scripts are provided in ZoneMinder which support a number of serial or network protocols but it is likely tha

be emphasised that the control and capability elements of ZoneMinder are not intended to be able to support every camera out of the box. Some degree of development is likely to be required for many cameras. This should often be a relatively straightforwar

The best places to look for errors are in the system error log (normally /var/log/messa}{\insrsid2383329 ges on RedHat), the}{\insrsid150409 Zo
neMinder logs, and the web server log (/var/log/httpd/error_log unless otherwise defined). There should be something in one of those that gives you some kind of tip off.

Device configuration. If you can't get your cameras to work in ZoneMinder, firstly make sure that you have the correct settings. Use xawtv or something like that to check for settings that wor}{\insrsid12017992 k and then run zmu -d <device}{
\insrsid150409 > -q -v to get the settings. If you can't get them to work with that then the likelihood is t
hey won't work with ZoneMinder. Also check the system logs (usually /var/log/messages) for any video configuration errors. If you get some and you're sure they're not a problem then switch off ZM_STRICT_VIDEO_CONFIG in zmconfig.pl or the \lquote options
\par {\listtext\pard\plain\s15 \f2\fs20\lang2057\langfe1033\langfenp1033\insrsid150409 \hich\af2\dbch\af0\loch\f2 o\tab}Start simple. Begin with a single monitor and single zone. You can run the zmc capture daemon from the command line as 'zmc -}{
\insrsid12017992 -device <device>}{\insrsid150409 ' (or whatever your video device is). If it returns immediately there's a problem so check the logs, if it stays up th
en 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 ano
ther user as some files may not be accessible. If you'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 brea
k ZoneMinder, I'm not a PHP guru but setting safe mode may prevent your PHP files from running certain programs. You may have to set configuration to allow this. Also since the daemons are started by your web server, if it dies or is shut down then the da
emons 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.}{\insrsid2383329 If everything else works but you can\rquote
t get images in your browser a likely cau
se is a mismatch between where your web server expects to execute CGI scripts and where you have installed the zms streaming server. Check your server configuration for the correct CGI location and ensure you have supplied the same directory to the ZoneMi
nder configure script via the \endash with-cgidir option. }{\insrsid150409
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 th
an your system can handle. The size it requests is base on the following formula, ring buffer size x image width x image height x 3 (for 24 bits images) + a bit of overhead. So if for instance you were using 24bit 640x480 then this would come to about 92M
b
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{\*\fldinst {\insrsid2383329 HYPERLINK "http://www.redhat.com/docs/manuals/database/RHDB-2.1-Manual/admin_user/kernel-resources.html" }{\insrsid1774400 {\*\datafield

You can also sometimes get shared memory errors if you have changed the monitor image size for instance. In this case i
t 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.}{\insrsid150409
Use the ipcs and ipcrm system commands to check and remove }{\insrsid2383329 segments}{\insrsid150409 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 version 0.9.8 ZoneMinder has used short PHP open ta
gs to output information, so instead of something like this '<?php echo $value ?>', it will be something like this '<?= $value ?>' which is easier and quicker to write as well as being neater. More information about this directive can be seen at the follo
. However although by default most PHP installations support this form, some will need to have it switched on explicitly. To do this you will first need to find your
php.ini file (do a 'locate php.ini' or 'find / -name php.ini'. Be aware however that sometimes you might find more than one, so ensure you identify the one that is actually being used. You will then need to find the line that starts 'short_open_tag = ' an
d
change the Off value to On. This will correct the problem. However in some cases you may have explicitly switched it off, so that XML compliant documents can be more easily served, or you may even not have permission to edit the file. In this case you ca
n
go into the web directory of ZoneMinder and run 'sh retag.sh' which will replace all the short open tags in the files themselves with the longer variant. You will obviously have to remember to do this for each subsequent version of ZoneMinder that you in

You can prevent this information from being emitted by set
ting 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 s

Unsupported palettes. ZoneMinder currently is designe

you have multiple USB cameras on one bus then it can appear as if ZoneMinder is causing your cameras to fail. This is because the bandwidth available to cameras is limited by the fairly low USB speed. In order to use more than one USB camera with ZoneMind
e
r (or any application) you will need to inform the driver that there are other cameras requiring bandwidth. This is usually done with a simple module option. Examples are usb_alt=<n> for the OV511 driver and cams=<n> for CPIA etc. Check your driver docume
ntation for more details. Be aware however that sharing cameras in this way on one bus will also limit the capture rate due to the reduced bandwidth.
Incorrect libjpeg.a detection. It seems to be the case that in some cases the library file libjpeg.a is rep
orted 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 usual
ly need to ensure you have gcc and g++ installed (though they are often the same binary).
Httpd and zms memory leaks. It has been reported by some users with RedHat 9 that the zms process fails to terminate correctly when the controlled window is killed and also that it, and it\rquote
s associated httpd process, continue to grow in memory size until they kill the system. This appears to be a bug in early versions of apache 2. On other systems it may appear that zms is leaking and growing. However what grows is the
total and shared memory size while the non-shared memory size stays constant. It's a little odd but I think what it happening is that as zms picks images out of the shared memory ring buffer to display, as each slot is read the size of that bit of memory
is added to the shared memory total for the process. As streamed images are not read consecutively it's a semi-random process so initially most of the buffer slots are new and the shared memory size grows then as time goes on the remaining unaccessed slot
s
reduce until once all have been read the shared memory use caps out at the same size as the actual segment. This is what I would have expected it to be in the first place, but it seems to do it incrementally. Then once this total is hit it grows no furth
er. As it's shared memory anyway and already in use this apparent leak is not consuming any more memory than when it started.

\f1\fs20\lang2057\langfe1033\cgrid\langnp2057\langfenp1033 {\insrsid4000360 FEATURE \endash The video generation interface has been re
designed and expanded. This allows you to see what videos have been generated previously and manage, view or download them.}{\insrsid7476161
You can also specify more precisely what input and output options to pass to ffmpeg and what video formats you want to support. These options are available from the Options->Tools view.}{\insrsid4000360
\endash A new timeline view has been added. This is an enhanced graphic activity view that represents events as colour coded bars on a time based chart. Passing you}{\insrsid12146333
r mouse over the activity will display images and details from the events in the chart.}{\insrsid10438658 }{\insrsid12146333 You are able to choose whether you see this view or the traditional events vi
ew as a default. Since this view can be a large file and dynamic loading of event images can be bandwidth intensive this preference can be specific on a bandwidth specific basis. The option to switch between the traditional list and the timeline view is a
vailable at all times however. IMPORTANT NOTE: }{\insrsid10438658 This view is }{\insrsid12146333 a beta version only and due to extensive use of CSS currently only renders correctly on}{\insrsid10438658 }{\insrsid12146333
FireFox type browsers. Even then as it can use huge numbers of elements it is possible it may degrade or cras
h your browser. Specifically Internet Explorer seems to get totally confused and renders some elements twice and others in the wrong place etc. I hope to remedy this situation for the next release but for now using this view with IE is not recommended. }{
\endash References to the video device files are now expressed as full file paths rather than just numbers. This allows files other than /dev/videoX to be used easily.
\par {\listtext\pard\plain\s27 \f2\fs20\lang2057\langfe1033\langfenp1033\insrsid4000360 \hich\af2\dbch\af0\loch\f2 o\tab}FIX \endash Integration with all versions of ffmpeg, including CVS, is now supported. At least un
\endash Monitors can now use a file path as a video source. This allows you to use scripts such as wget or other webcam type applications to generate your images which can then be fed into ZoneMinder as a monitor and analysed and archived etc.
\endash Users can now be defined with a maximum bandwidth setting. This prevents low privilege users from swamping the system with lots of high bandwidth streaming.
\endash Debug levels for the binaries can now be controlled in a limited fashion from the Options screen. For more details see the help on the Options->Tools->ZM_EXTRA_DEBUG* options.
\endash The user authentication methods have been revised to separate authentication at the web front end from authenticat
ion at back end streaming. Thus there are now several more authentication options to allow more fine control. The most significant of these ZM_AUTH_TYPE now offers a choice of \lquote remote\rquote
authentication which allows you to use a third party authentication sch
eme such as http basic authentication and have that users name passed via the REMOTE_USER environment variable. Providing there is a user of that name known to ZoneMinder they will be automatically logged in. Be warned however that there is no facility fo
r this user to log out so ensure that you do not lock yourself into a low privilege account. Also you may need to remove user cookies when you change authentication methods.
\endash Users now have a \lquote control\rquote permission which determines whether they are a
ble to control PTZ style cameras. As with the other permissions there are three levels, None, View and Edit. Unlike some of the other options it may not be obvious what levels do what. The \lquote None\rquote
level bars access to any control functionality, the \lquote View\rquote level permits users to actually control the positioning and settings of a camera }{\insrsid16728107 (rather than just look at them which is what might be expected) }{
\insrsid10683511 and the \lquote Edit\rquote level allows users to modify the various control capabilities.
Jpeg errors are now reported via the generic ZoneMinder error and debug mechanism rather than just to standard output as is the default in libjpeg.

h the console view has been reduced. This is especially significant where you may have lots of monitors.
\endash Paths to the control scripts were hard coded with a full path. This broke the packaged ZoneMinder distributions so the paths are now relative to the ZM_PATH_BIN config unless they start with a \lquote /\rquote .

\endash Motion detection can now be temporarily disabled from the watch view. This is most useful with PTZ type cameras where you can switch off motion detection whilst repositioning the camera. Just don\rquote t forget to switch it
\endash Monitors can now be defined with a default scale. This allows you to reduce the
viewing size of a monitor that might be capturing at a large image size. This works in conjunction with the bandwidth specific scaling so if you bandwidth setting is 50% and your monitor is also 50% then at that bandwidth you will be viewing at 25%. This
is to ensure that all monitors maintain relative scaling at all bandwidths.
\endash In the past there has been some confusion about what the \lquote prev\rquote and \lquote next\rquote
options do when scrolling through events. They actually move to the previous or next event in the list from which the event was selected rather than in chronological order. Previously this order was descending date/time in most cases meaning t
hat the previous event would be one that occurred after the current event. In order to prevent this confusion and allow users to define a default order which they prefer there are now two more options in Options->System called ZM_EVENT_SORT_FIELD and ZM_E
V
ENT_SORT_ORDER which allow you to choose your own sort type and order. The default for these is now date/time ascending meaning oldest first which is opposite to the previous default and you will need to update these options to retain the previous behavio
ur. Note also that this ordering applies only to event lists and not the \lquote last x events\rquote in the watch window which are still newest first.

FEATURE \endash 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.
There has long been a dichotomy between the functions that can be applied via interactive filters versus back
ground saved filters. This release addresses this to some extent allowing you, for instance, to archive or unarchive matching events, or edit them as described above. This is not a complete solution and it is expected that the functionality will converge
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 configurat
ion has been rewritten to provide all configuration options as members of the configuration class which are initialised once on startup and then can be accessed directly with no further overhead.

an alternative method of parsing the output from network ca

p
cre. If the option is off or libpcre is missing then a more basic parsing is used instead. This new method should be slightly faster as it does not have the overhead of regular expression parsing, however this also makes it slightly more inflexible. If yo
u 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.}{\insrsid15291753

\endash Brightness, colour, hue and contrast are now saved persistently for a monitor rather than being reset each time the system is restarted. This feature is based on a patch submitted by forum user \lquote oskin\rquote .
\endash In previous versions the events folder has been keyed by the monitor name. Th
is has caused problems in the past with various characters appearing which are legal in names but not in filesystems. From this version all files related to monitors are keyed on the monitor id rather than the name. To help you navigate through these file
s the monitor name still exists but as a link only. Please ensure you run zmupdate.pl to update your events directory.

ons->Web. You can also control the width or height of these thumbnails but should only set one dimension only and leave the other blank or zero.

http://ffmpeg.sourceforge.net/}}}{\insrsid1732201 ) for video generation and processing. Recently a new ve
rsion (0.4.9-pre1) was released which changed the interface that ZoneMinder uses and so broke compilation. This version will detect which version of ffmpeg you have and compile accordingly.
If you use filters to send event notification emails you can now have them sent in HTML format. This is done automatically if your mail body includes a \lquote <html>\rquote token,
\endash An experimental feature has been added which lets you view several events in sequence. In event listing you can check the events you want to view and then click the \lquote View\rquote
button. This will allow you to navigate through only those events in the normal manner (via Prev and Next links) but also to view them in sequence by clicking on the \lquote Play All\rquote
link. This will replay each event and then automatically move onto the next one. You can stop this progression at any time by pressing \lquote Stop\rquote (which only stops the seque
nce and not the currently playing event). The timing of the replay is done depending on the calculated length of the event (plus one second) and so may not exactly correspond to the real event length. In particular this is unlikely to work if replaying ev
ents using MPEG video and buffering players as the timing will likely be incorrect. If you are viewing an event but haven\rquote t checked any in the list the \lquote Play All\rquote button will just work down the current event list.
\endash Previously events have been created even if only one frame has generated an alarm. This has not always been desirable as sometimes glitches and flickers create large numbers of events, however no mechanism ex
isted for limiting this. In this version you can now specify the minimum number of consecutive alarmed frames that are necessary to create an event. This is the \lquote Alarm Frame Count\rquote
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 bufferi
ng significantly and also reduces the chance of errors caused by multiple simultaneous image generation.
\endash The generated MIME types when creating streamed video were previously assigned by zms depending on which of a limited number of output format
s was specified. This has now been changed so that the ffmpeg libavformat library itself now generates these identifiers. The consequence of this is that many more video formats supported by your version of ffmpeg should now be available via zms.
\endash When viewing a single frame of an event you can select a \lquote stats\rquote
link to view the statistics that apply to that frame, if you have the RECORD_EVENT_STATS option switched on. This can be used to help configure your zones for optimal motion detection. Previ
ously only pixel count values were displayed here which made it difficult to configure zones configured in percentage terms. These values are now displayed in both pixel and percentage terms to assist in zone configuration. Note that the percentage values
are based on the current size of the zone so if this is changed then the value displayed will not be applicable at the time of event generation.
\endash When doing motion detection an extra blob, that could never be removed, was sometimes included. This could have caused false triggering and has not been corrected.
\endash A problem was reported whereby when using bulk frame records to reduce database load the last frame record was not written. Replaying the event via the web interface resulting in the event be
ing truncated. A correction has been made so prevent this and ensure that the last frame of an event is always recorded.
\endash If an analysis daemon terminates abnormally or the host computer crashes then events can be left in a state whereby they effectively have zero length and are useless. A change to zmaudit.pl was made such that any \lquote open\rquote
events such as this which have not been updated for at least five minutes are closed and updated to reflect their actual content so that they may be viewed or saved. Events recovered in this way are named with a \lquote (r)\rquote
\endash In more recent versions of MySQL the password hash generated is 50 characters long, which overflows the previous password field in the database which was only 32 characters long. This field has been extended to 64 characters to accommodate this.
The montage view had an error whereby the refresh timeout for stills was mislabelled causing continuous refresh attempts which rendered the view mostly unusable. The constants in question are now correctly referenced.
The default, bandwidth specific, rate and scales were not always used as the records in the database were misnamed. This is now corrected though you may need to reset the values that were used previously as these will be lost if they had been changed.
\endash It was previously the case that old images could be left in the \lquote images\rquote directory for a long period, sometimes resulting in incorrectly assuming correct operation. A fix was made to zmaudit.pl which mod
ified the previous clean up of old WAP images so that any old images left in this directory are removed after a short period. Please ensure that if you have customised the web interface and have images you wish to keep that they are not left in the tempor

\f1\fs20\lang2057\langfe1033\cgrid\langnp2057\langfenp1033 {\insrsid1732201 FEATURE \endash The default replay rate and live and event scale settings are now configura
ble on a per bandwidth basis rather than globally. This allows you to view at full scale when you have high bandwidth and at smaller scales when you do not have so much resource. You will need to re-configure your previous defaults as they will be lost.
\endash Two new filter elements have been added. These are disk blocks and disk percentage. These are event independent and return the amount of disk space used on the event partition in terms of disk blocks or percentage as returned by }{
\i\insrsid1732201\charrsid13107570 df(1)}{\insrsid1732201 . Thus filters using these criteria will either match all events or none at all d
epending 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 exceed
s
a certain value. Included in the database schemas for both new installations and upgrades is a sample filter called PurgeWhenFull which can be used to do this. It is initially not set to do anything automatically so if you want to use it, you should load
it into the filter selection window, modify it to your taste and then save it, selecting \lquote auto delete\rquote
. 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 even
ts to match and thus be deleted. Using a limit ensures that only a small number are affected at any one time.
\endash Filters can now be defined to automatically execute an external script or program of your choosing. This can be specified when the filte
r is saved. Note that for security reasons this cannot be just any arbitrary command but must be readable and executable by your web server effective user. The script or program you specify here will be executed in the events root directory once for each
event and will be passed one parameter containing the relative path to the event directory. This will normally be of the form }{\i\insrsid1732201\charrsid13107570 <MonitorName>/<EventId>}{\insrsid1732201
so it it possible to determine both the monitor and event in question from the path. Note also that a flag
is set per event as with other auto actions indicating that an executable script has been run on that event and so to exclude it from subsequent matches. However if you have several filters all with executable scripts you will find that only the first get
s executed as the flag will be set following successful completion and so no further scripts will be run on that event. Successful completion is indicated by the script returning a zero exit status, any other status indicates an error and the }{
\i\insrsid1732201 executed }{\insrsid1732201 flag will not be set.

\endash The zone definition have been updated so that selecting the various types of zones etc only disables those options you no long
er have access to rather than wiping them out entirely. This is also true of the zone when saved. Thus you can now more easily change a zone to be temporarily inactive for example and have your previous active settings restored in the future.

option. This allows one or both of live or event streaming to be in this format rather than motion JPEG style as before. Note however that is still somewhat experimental and may not work on your system. The reason for this is due to the variation
in plugins and video movie formats. Currently I have got it working well with browsers on Windows platforms using the Windows Media Player plugin and the 'asf' video format. I have also managed to get event streaming working on Mozilla using mplayer (I th
i
nk) though it jumps in and out of it's place in the window a bit. I would appreciate any feedback or advice on formats and plugins that work on your system. Also note that video streaming tends to get buffered before being displayed. This can result in th
Motion JPEG Capture. Previously image capture from network devices has been limited to single stills capture only. This has now changed and if you entered a remote camera path that returns the }{\i\insrsid1732201 multipart/x-mixed-replace}{
MIME type then this will be parsed and images extracted from the stream. This is much faster than before and frame rates can be as fast now with network cameras as with capture cards and video. This feature also has the side-effect that one ZoneMind
er installation can use another as a remote video source.
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 stre
ams which was screwing up the headers. I believe this to be because the initial header had no content-length header, as the length is indeterminate. So I have added a zero content length header which I believe fixes the problem though perhaps not in the b
st way. I have also made the installation link the existing zms binary to nph-zms so that you can now use zms in non-parsed-header mode. If it detects it is in this mode then the content-length header is not output, though several other additional ones ar
e. In nph mode the 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 m
eant that a lot of database activity was taking place as each captured frame required its own entry in the database. The frames table has now been reorganised so that 'bulk' frames may be written at defined intervals to reduce this database activity. The
records act as markers and individual frame timings are interpolated in between. Bulk frames are only used when no alarm or motion detection activity is taking place and normal frame records are kept otherwise.
Event List Ordering and Scrolling. It was previously the case that the \lquote Next\rquote and \lquote Prev\rquote
buttons on the event view did not always go to the event that was expected and sometimes disappeared altogether. This behaviour has now been modified and these buttons will now take you to the next and previous ev
ents in the list 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.
detection parameters can be defined either in terms of total pixels or as a percentage. This percentage was defined relative to the size of the image as a whole. However this was difficult to calculate or estimate especially with several zones of varying
sizes. In version 1.19.0 this has been changed so that the percentage relates to the size of the zone itself instead. This should make calculations somewhat easier. To convert your existing zones you can run zmupdate.pl with the \endash
z option, though this should be done only once and you should backup your database beforehand in case of error.
Console View System Display. The console display was slight revamped to indicate disk space usage (via the \lquote df\rquote command) on the events partition,
anges applied in version 1.18.0 to prevent invalidate entries in the zone definition form actually had the opposite effect due to JavaScript treating everything as a string and not a number (e.g. 5 is greater than 123). This is now corrected.
and Scales. You can now specify (in the options dialog) the default scale you would like to view live and event feeds at. You can also give a default rate for viewing event replays.

rame Buffer Size. Previously it was possible for frames being sent from the analysis daemon to the frame server to exceed the defined maximum buffer size in which case the write would fail. It is now possible to define a larger size if necessary to preven
t this. Note that you may have to adjust your system configuration to accommodate this. For further details check the help for the ZM_FRAME_SOCKET_SIZE option.
Filter Name Duplication. Following recent changes to the filters table, several people reported t
hat when saving filters they actually got a duplicate. This resulted in several copies of filters all with the same name as the constraint on unique filter names was not present. Well it is now so when upgrading your database all the filters will be renam
ed from \lquote myfilter\rquote to \lquote myfilter_<id>\rquote where \lquote <id>\rquote
is the id number in the database (which is then removed). In general the higher the id number the more recent the filter. So you should go through your filter list deleting old copies and then rename the last one back to it\rquote s original name.

Database Upgrade Change. Users upgrading from releases prior to 1.18.0 please note that now as part of the upgrade process all your filters will have any a
utomatic actions unset. This is because the previous affinity to a particular monitor has now been removed and you may be left with several filters all doing the same thing to all of the events or have filters which for instance delete events on only one
monitor but which now would delete them for all of them. It is recommended that you review your list of saved filters and delete duplicates before adding any monitor specific terms and resetting the actions for any that remain.

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 pret
ty 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
bug that had existed previously in YUV conversion which caused incorrect conversions for certain values. The other two main areas of optimisation are in the Blend and Delta image functions. Normally when doing motion detection the analysis daemons spend
a
bout 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 de
l
tas (or differences), a simple RGB average and a Y channel calculation. Historically the RGB one was faster however with the optimisations the Y channel calculation (which is more accurate) is now 15-20% faster and so has become the default though you can
select either method by the ZM_Y_IMAGE_DELTAS configuration option. A new method of image blending has also been added which is up to 6 times faster than the old one which is retained for compatibility and because in some unusual circumstances it may stil
l be more accurate (see the ZM_FAST_IMAGE_BLENDS option for details). Altogether these optimisations (along with other common sense ones such as not maintaining a reference image in \lquote Record\rquote
mode where it is not used) significantly reduce the CPU load for m
ost systems, especially when alarms are not in progress. If an alarm is detected then a lot of file system and database activity takes place which is limited by the speed of these resources so the gain will not be as much.
ent has previously indicated that basic authentication for network cameras could be used by entering a hostname of the form of <user>:<pass>@<hostname>. This was not actually the case as the relevant authentication header was never sent. This is now fixed
Monitor Independent Filters. Previously filters were closely tied to a monitor and a new
filter had to be created for each monitor. This has now changed and filters can now specify an associated monitor in the same was as other parameters. Links have now been added to the main console view to allow you to view lists of events from all monito
r
s in one and saved filters can now affected as many or as few monitors as you wish. IMPORTANT: Please note that as part of the upgrade process all your filters will have any automatic actions unset. This is because the previous affinity to a particular mo
n
itor has now been removed and you may be left with several filters all doing the same thing to all of the events or have filters which for instance delete events on only one monitor but which now would delete them for all of them. It is recommended that y
ou review your list of saved filters and delete duplicates before adding any monitor specific terms and resetting the actions for any that remain.
New Filter Operators. Two new filter operators and their inverse have been added. You can now indicate whether a value is in a set of other values, for example \lquote cat\rquote is in the set of \lquote cat, dog, cow, horse\rquote
. You can also use regular expressions so \lquote cat\rquote matches \lquote ^c.*\rquote . The \lquote not in set\rquote and \lquote not matches\rquote operators are also available.
Additional Scales. Enhancements to the scaling algorithm mean that non binary scales are now just as easy to apply, thus new scales such as 0.75x have been added. Others can be easily included if necessary.
Montage Sizing. The montage view allows you to view all of your active cameras in
one window. However if your cameras are different sizes then this becomes very untidy. You can now constrain the image size of each monitor in this view to a fixed size with the ZM_WEB_MONTAGE_WIDTH and ZM_WEB_MONTAGE_HEIGHT configuration options. Monito
r images will be enlarged or reduced as necessary.
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 ma
y 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.
Monitor Name Constraint. The name given to a monit
or is used in file paths and several other areas. Thus it is important that it follows certain conventions but up until this release these names were unrestricted. The monitor form now limits monitor names to alphanumeric characters plus hyphen and unders
Timestamp Change. Traditionally ZoneMinder has time-stamped each image as it is captured. This ensures that all images have their capture time recorded immediately. However there are several side-effects which may be undesirable. Firstly the time and
resource is spent time-stamping images that are not recorded and which are discarded, secondly the timestamp is included in any motion detection and may potentially trigger an alarm if detection parameters are very sensitive. The third effect is that as t
he 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_TIMESTAMP_ON_CAPTURE configuration option, to indicate whether the timestamps should be added on capture, as before, or only added when the image is viewed or recorded. Setting it to this later value allows timestamps to be added to scaled images.
Scaleable Stills View. The stills view of a monitor (when streaming is not available or desired) is now scaleable in the same way as the streamed view.
Double Buffered Stills View. The stills view has now been
restructured to allow a double buffering approach. Thus a new image is loaded in the background and only written to screen when complete. This removes the refresh flicker that means that the screen blanks periodically however uses more JavaScript so may n
ot be suitable for all platforms. Whether ZoneMinder uses double buffering or not is controlled by the ZM_WEB_DOUBLE_BUFFER configuration option.
Fixed Length Event Bug. A bug was reported whereby the fixed length events that could be specified for use in R
ecord or Mocord mode could sometimes result in events a multiple of that length. So events that were meant to be 15 minutes long could sometimes be 30 or even 45 minutes. This was especially the case with monitors that had low frame rates. This is now fix
Pending Process Bug. A bug was found whereby a process that was scheduled to be started in the future (due to repeated failures) would drop out of the pending queue if a further explicit restart was attempted. This is now fixed.
Strsignal Function. The strsignal function was included from version 1.17.1 however this is not ubiquitous on all distributions. The existence of this function is now tested for by the configure script and it is not used if not present.
Add Max Alarm Threshold. Previously the alarm threshold (which is the amount a pixel has to differ from it\rquote s counterpart in the reference image) existed only in a \lquote minimum\rquote form meaning pixels that were more different matched. A max
imum has now been added to assist in screening out large changes in brightness. In addition to this a number of new consistency checks have been added to the zone definition form to try and prevent bogus or invalid settings.
arly requested feature is that of adding extra information to allow diagnostics of the process of image detection. This has previously been somewhat hit and miss but in this version a new configuration option ZM_RECORD_DIAG_IMAGES has been included to all
o
w this. This option will generate several images for each captured frame in an alarm including each reference image and a series of images containing the image differences at various stages in the process. It is not possible to record these for the image
prior to an alarm but those following it are included and should assist in tuning the zones to provide optimal motion detection.
Event Images Renamed. The capture and analysis images recorded during an event have been renamed from capture-???.jpg to ???-cap
ture, 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 \lquote perl zmupdate.pl \endash r\rquote as an appropriately privileged or root user.
Version checking. ZoneMinder will now optionally check for new versions
of itself at zoneminder.com. This is done with a simple http get and no personal information otherwise than your current version of ZoneMinder is transmitted or recorded. If new versions are found you may be alerted of them via the web interface. This is
an initial step towards enhancing and automating the upgrade process.

s detection of browser capabilities to prevent the Cambozola Java applet being used. However sometimes the opposite effect

\f1\fs20\lang2057\langfe1033\cgrid\langnp2057\langfenp1033 {\insrsid1732201 Version Numbering. ZoneMinder version numbers have now changed. This is to allow more frequent \lquote point\rquote releases which are expe
cted to happen for instance whenever new language files are included. Previously all releases had the same version increment so it was difficult to tell the significance of any particular release. Now the version number is in the }{\i\insrsid1732201 x.y.z
}{\insrsid1732201 format where a change in }{\i\insrsid1732201 x}{\insrsid1732201 signifies a major fundamental or architectural rework, a change in }{\i\insrsid1732201 y}{\insrsid1732201

ons which would not be recommended as important to all users. As ZoneMinder has been referred to by the point release up until now, e.g. .15, .16 etc the next number in that sequence has been retained for continuity and to avoid having any ambiguity in ve
Language Support. ZoneMinder now allows specification of system and user specific languages other than UK English. These languages are given in language files named zm_lang_}{\i\insrsid1732201 nn_mm}{\insrsid1732201
.php which can be created from the default zm_lang_en_gb.php file. If your language is not included then please consider doing a translation by checking this file and submitting your changes back for inclusion in future releases.
Syntactic Improvements. Previously setting \lquote NOTICE\rquote errors on in PHP would flag tens or hu
ndreds of violations in the ZoneMinder web files. Whilst not strictly errors this represented sloppy coding and sometimes covered up genuine bugs. All the files have been revisited and revised to ensure that a many of these problems as possible have been
eliminated and only the very few where the fix would be significantly less optimal than the problem remain.
Stream Scaling Resizing. Previously when watching a stream and modifying the scale of the streamed feed only the actual feed would change size and th
e containing frames and windows would remain the same. This was fine for changes to smaller scales but problematic for larger scales. This has been changed for that the window and frames will now resize appropriately.
\f1\fs20\lang2057\langfe1033\cgrid\langnp2057\langfenp1033 {\insrsid1732201 Run States. Instead of the old \lquote start/stop\rquote
links the current system state is now a link which takes you to a dialog which allows you to start, restart or stop the system. You can also save the current run state which basically takes a snapshot of the current monitor functions
and saves that. You can then reselect that state later which basically involves resetting the monitors to have these saved functions and then doing a system restart.
New Monitor Functions. Instead of Passive, Active, and X10, the modes are now Monitor (=
old Passive) which just allows you to watch the feed, Modect (= old Active) which is MOtion DetECT and which will capture events as previously, Record which continuously records with no analysis and MoCord which is a hybrid of Modect and Record and which
w
ill continuously record but also do motion detection and highlight where this has occurred. The Record and Mocord functions both records events whose length in seconds is defined by the 'Section Length' monitor attribute. You can additionally specify a 'F
rame 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 controlled outside of zmdc and zmpkg. Additionally the X10 triggers may now be specified in an X10 section. This has changed to allow for other types of triggers to be added more easily.

by default. You can list all of the events if you like by choosing the appropriate option. There are shortcuts to pages of events at the top of the listing. If these produce strange looking sequences like 1,2, 3, 5, 9, 17, 37 etc this is deliberate and us
es an exponential algorithm intended to allow you to quickly navigate through the list to a particular page in the minimum number of clicks.
Scaleable Streams. Event and monitor streams can now be scaled to a certain extent allowing you to view at a differe
nt resolution than that captured. This area may be somewhat incomplete especially in terms of monitoring at a higher screen size where the frame is not adjusted properly.
Variable Frame Rates. Event streams can now be viewed at various rates allowing faster review (if your bandwidth allows) to long events, or slower for more precision.
Scaleable/Variable MPEG generation. Generation of MPEG videos now also allows you to specify the scale relative to the original image and also the frame rate. Again, for long
events captured in the perpetual recording modes this will allow a faster review of the period the event covers.

A problem was found if using the zmf frame server and greyscale images. The option to colourise JPEG images is intended to be used to ensure that all JPEG files are written with a 24 bit colourspace as certain tools such as ffmpeg require this. However

Removed use of \lquote zmu\rquote binary from zmwatch.pl and zmx10.pl. Previously these scripts had used zmu to determine last image time and alarm state information. The use of this script was a bit overkill and the introduction of user permissions
complicated matter slightly so these scripts now access the shared memory directly.
Shared memory permissions. Following introduction of a user permissions system the previous 777 mode for shared memory was deemed insecure. Consequently from now on shared
memory is only accessible from the owner. This means that zmu will only work when run as root or the web user unless you set it setuid where it should still be secure as it will require authentication.

New contrast/brightness etc adjustments feature. This accessible from the Settings link on the monitor window. It's fairly basic at present
but should work for most types of cameras. If you have any device or driver specific auto-brightness, auto-contrast etc enabled the changes you make may appear to work but may be overridden by the auto feature immediately so check for that if your changes
do not appear to be having an effect. Also if you have a number of cameras being multiplexed onto one device then any changes here will probably affect all your cameras.

ids as a comma-separated list (no spaces) to the appropriate field. Users limited to specific monitors may not create or delete monitors even if defined with monitor edit permissions.
Some windows now (optionally) use a JavaScript timeout to refresh themsel

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 every second for a while, stopping if the connection is made. Thanks to Todd McAnally for the initial suggestion.

l now get a snapshot of the event frame with the highest score. This is to enable you to quickly see what the event was about without having to watch the stream or view all the static images.
Make delta times variable precision. A couple of problems had be
en reported where long events got negative durations. This was due to an overflow in a time difference routine. This had been operating on fixed precision allowing high precision for short deltas. This routine has been changed to allow variable precision
and events will now have to be several days long to wrap in this way.
Fixed round detection problem. Although the existence or otherwise of the \lquote round\rquote function is correctly detected, the appropriate header file with the results of this test was not included which was not helpful. This has been corrected.
OPT_MPEG bug. A bug was reported (by Fernando Diaz) where the results of the ZM_OPT_MPEG configuration variable was not correctly imported into the scripts. This now happens as intended.
Fixed zmvideo.pl event length bug. The zmvideo.pl script which is used to generate video MPEG files tries to calculate the correct frame rate
based on the length of the event and the number of frames it contains. Previously it did not take account 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 en
coded 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.

Fixed filter bug. A bug in the zmfilter.pl script was detected and reported by Ernst Lehmann. This bug basically meant that events were not
checked as often as they should have been and many may have been left out for filters that had no time component. The script has now been updated to reflect Ernst\rquote s suggested changes.

sly sensible suggestion from Carlton Thomas this module has been removed from zmconfig.pl. Originally Term::ReadKey was in there for funky single character unbuffered input but that has long since disappeared so just regular perl input methods are used no

Added stats view \endash If you have the RECORD_EVENT_STATS directive set and are viewing a still image from an event you can now view the statistics r
ecorded for that frame. This tells you why that frame triggered or participated in an alarm. This can be useful in tuning the various motion detection parameters and seeing why events occurred.
New video palette support \endash 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 mi
nd though that YUV palettes are converted into RGB internally so if you have the choice RGB24 may be faster as it's the 'native' format used within.
Added preclusive zones \endash Added a new zone type, the preclusive zone. For full details see the relevant section above but in brief this is a zone type that if alarmed will actually prevent an alarm. This completes the pantheon of zone types I think.
Fixed Mozilla JavaScript \endash Various JavaScript functionality did not function on Mozilla, Netscape and other browsers. This is now (hopefully) fixed.
Allow image and mpegs to be attached to emails \endash Added new tokens (%EI1%, %EIM% and %EV%) to the filter emails. This allows the first alarm image, most highly scored alarm image and an alarm MPEG to be attached to alarm
notification emails. Use %EV% especially with care!
Fixed possible motion detection bug \endash I found a few double declared local variables left over from the rewrite. This may have affected the motion detection algorithm. Fixed now anyway.
Modified scoring \endash Alarm scoring has been modified to give more granularity for smaller events. This will have the effect of raising the scores for small events while large ones will still be about the same.
Fixed /cgi-bin path problem \endash Previously you could specify the real path to you cgi-bin directory if you have one but not the web path. You can now do both.
Improved video handling in browser \endash 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.
Added ffmpeg support \endash 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 vide
os 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.
Colourise greyscale image files \endash In past versions, captur
ed greyscale images were stored as JPEG files with a corresponding greyscale colourspace. This saved a small amount of space but meant that mpeg_encode had to do a conversion to encode them, and ffmpeg just fell in a heap. Now you can optionally opt to ha
v
e greyscale images saved as full 24 bit colourspace images (they still look the same) at the price of a small penalty in CPU and disk but allowing you to easily and quickly create MPEG files. This option is one by default but can be switched off if you do
Fast RGB diffs \endash 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 dif
ference. 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 m
a
y be slower especially on old machines. There is a slight double whammy here if you have a YUV palette for capture and set this option off as the image will be converted to RGB and then partially converted back to get the Y value. This is currently very i
Fixed STRICT_VIDEO_CONFIG \endash 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.
Web colour change \endash I thought the old red, green and amber text colours were just a bit too gaudy so I've toned them down a bit. Hope you like them!

Added zmu -q/--query option - There is now a new query option for zmu. When
combined with -d it gives the config of the device and when used with -m it dumps the current settings for the monitor and zones. Mostly useful for bug reporting. The previous version of zmu used with just -d gave this information for a video device by de
fault. This now requires the -q option also to bring into line with it's -m equivalent.
Can now retag PHP files if necessary - Version 0.9.8 was the first version to use short_open_tags in the PHP files. This caused grief to some people so this script will put them back to the long verion.
Frame and event lengths fractional - A new field has been added to the Frames table. This is 'Delta' a
nd is a fractional number of seconds relative to the event start time. This is intended to support the real-time playback of events rather than just 'as fast as possible' or with a configured delay as at present. The event length is now also fractional.

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.
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.

ough 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.
Zone Definitions - Allow zones to be defined according to a colour coded bitmap or as polygons. Cu
rrently 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.}{\insrsid12454246
Work has already begun on this feature.}{\insrsid1732201
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.
Extend the API. Well ok it's not really got an API yet but the image data is held in shared memory in a very simple format. In theo
ry 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 utili
ty 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. Zo
neMinder will interpolate, add a bit of magic, and recommend settings that will support this selection automatically thereafter. The hooks for this are already in to some extent.
Add sound support to allow a captured audio channel to be associated with a video device. }{\insrsid12454246 Work on this feature has already begun.}{\insrsid1732201
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.
