Alarm Settings
Figure 47: Alarm Settings
The Alarm Settings page contains pre/post alarm record time, alarm duration,
non-event record rate, and alarm video protection.
PRE-ALARM Record Time: The length of video that gets packed into the
alarm event before an alarm is triggered.
ALARM DURATION: The length of triggered alarm before it times out.
During the duration, if another same type of alarm is triggered, the timer
will be reset.
POST-ALARM Record Time: The length of video that gets packed into
the alarm event after an alarm is triggered.
NON-EVENT REC RATE: When set to NORMAL, the DVR will record
at normal rate according to the settings in the Record SETTING. When set
to I FRAME, the DVR will record at one frame per second to take less
space of the SD card.
