If you also have a small minimum pixel difference threshold this can cause multiple bogus alarms.

description=>"Should frame analysis try and be efficient in skipping frames",
help=>"In previous versions of ZoneMinder the analysis daemon would attempt to keep up with the capture daemon by processing the last captured frame on each pass. This would sometimes have the undesirable side-effect of missing a chunk of the initial activity that caused the alarm because the pre-alarm frames would all have to be written to disk and the database before processing the next frame, leading to some delay between the first and second event frames. Setting this option enables a newer adaptive algorithm where the analysis daemon attempts to process as many captured frames as possible, only skipping frames when in danger of the capture daemon overwriting yet to be processed frames. This skip is variable depending on the size of the ring buffer and the amount of space left in it. Enabling this option will give you much better coverage of the beginning of alarms whilst biasing out any skipped frames towards the middle or end of the event. However you should be aware that this will have the effect of making the analysis daemon run somewhat behind the capture daemon during events and for particularly fast rates of capture it is possible for the adaptive algorithm to be overwhelmed and not have time to react to a rapid build up of pending frames and thus for a buffer overrun condition to occur.",

description=>"Whether to check with zoneminder.com for updated versions",
help=>"From ZoneMinder version 1.17.0 onwards new versions are expected to be more frequent. To save checking manually for each new version ZoneMinder can check with the zoneminder.com website to determine the most recent release. These checks are infrequent, about once per week, and no personal or system information is transmitted other than your current version number. If you do not wish these checks to take place or your ZoneMinder system has no internet access you can switch these check off with this configuration variable",
description=>"What method windows should use to refresh themselves, choose either javascript or http",
help=>"Many windows in Javascript need to refresh themselves to keep their information current. This option determines what method they should use to do this. Choosing 'javascript' means that each window will have a short JavaScript statement in with a timer to prompt the refresh. This is the most compatible method. Choosing 'http' means the refresh instruction is put in the HTTP header. This is a cleaner method but refreshes are interrupted or cancelled when a link in the window is clicked meaning that the window will no longer refresh and this would have to be done manually.",
help=>"From version 1.18.0 ZoneMinder can use a double buffering method to preload still image prior to displaying them on screen. This reduces flickering and makes viewing still images a more pleasant experience. However some devices may not support the JavaScript/frames combination needed to make this possible in which case this option should be switched off. As this option uses JavaScript it will only have an effect if the ZM_WEB_REFRESH_METHOD option is set to JavaScript also.",
description=>"Whether to compact the montage view by removing status and FPS information",
help=>"The montage view shows the output of all of your active monitors in one window. This include a small menu and status information for each one. This can increase the web traffic and make the window larger than may be desired. Setting this option on removes all this extraneous information and just displays the images.",
introduction=>"There are now a number of options that are grouped into bandwidth categories, this allows you to configure the ZoneMinder client to work optimally over the various access methods you might to access the client.\n\nThe next few options control what happens when the client is running in 'high' bandwidth mode. You should set these options for when accessing the ZoneMinder client over a local network or high speed link. In most cases the default values will be suitable as a starting point.",

help=>"The top frame of the monitor window when monitoring a live feed in streaming mode contains a continuous stream of images. This option controls how often a new frame is sent to the browser when the monitor is idle, ie. not in alarm state. It makes little sense to set this too small as if it results in frames being sent much faster than they are being captured you will just get the same ones over and over. It should be set to be less or equal to the capture rate of the cameras you are using which will normally be between 2 and 25 Frames Per Second which maps to values between 500 and 40 being used here though your bandwidth may well limit how much can actually be sent. Note also that this is the update rate when no alarms are being generated, if an alarm situation occurs then the rate speeds up as per the next option so this can be set to a longer delay without you missing anything.",
description=>"What the maximum frame rate for streamed video should be",
help=>"When using streamed video the main control is the bitrate which determines how much data can be transmitted. However a lower bitrate at high frame rates results in a lower quality image. This option allows you to limit the maximum frame rate to ensure that video quality is maintained. An additional advantage is that encoding video at high frame rates is a processor intensive task when for the most part a very high frame rate offers little perceptible improvement over one that has a more manageable resource requirement. Note, this option is implemented as a cap beyond which binary reduction takes place. So if you have a device capturing at 15fps and set this option to 10fps then the video is not produced at 10fps, but rather at 7.5fps (15 divided by 2) as the final frame rate must be the original divided by a power of 2.",
help=>"A value of 1 sends the whole image to the browser which resizes it in the window, larger values scale down by that amount on the server before sending a reduced size image to the browser.
