3.6.2 Alarm Buffers Section
Each video stream can have an alarm buffer. Normally, the alarm buffer on a stream is a simply a
ring buffer that stores the last N captured images for the stream (N depends on the size of the
images being encoded and the size of the buffer). If an alarm condition is declared, however, the
alarm buffer will only continue to buffer post alarm images until the part of the buffer that is allocated
for post alarm buffering is full. At that point, buffering will stop, and the pre and post alarm images
held in the buffer will be retained until a new Alarm Buffer Arm command is issued.
Note that you will only be allowed to arm the alarm buffer if the Alarm Buffer Size and Post Alarm
Buffer Size parameters for the stream have been set to values greater than zero (see page 30).
Stream 0 Tab
Alarm Buffer State - Indicates the current state of the alarm buffer
for stream 0.
 Off = The buffer is disabled.
 Arming = The buffer is in the process of being armed.
 Armed = The buffer is armed and ready to react to an alarm
condition.
 Active = An alarm condition has been declared and the buffer is
actively buffering post alarm images.
 Done = The buffer has finished buffering post alarm images and
has stopped buffering.
Click the Arm Buffer button to arm the alarm buffer for stream 0. (If the buffer is in
a "done" state, this will arm the buffer and make it begin buffering again.)
Click the Disable Buffer button to disable the alarm buffer for stream 0.
Stream 1 Tab and Stream 2 Tab
The contents and operation of the Stream 1 tab and the Stream 2 tab are similar to the Stream 0 tab.
