•
Record Until RESET Received—
changes the beginning of the
postalarm recording period. If you select this option, postalarm
recording does not begin until the alarm is reset to its normal
state. Otherwise, the postalarm recording period begins when the
alarm is triggered.
•
Priority—
determines how alarms from this zone are sorted in the
Current Alarms window. Alarms notifications from zones with
Priority 1 are listed at the top of the Current Alarms window.
•
Alarm Time in Seconds—
contains the following options:
•
Prealarm—
indicates how much of the video captured before the
alarm occurs is appended to the beginning of a video segment of
an alarm event within this zone.
•
Postalarm—
indicates how much of the video captured after the
alarm occurs is appended to end of a video segment of an alarm
event within this zone.
•
Realarm—
indicates how long after an alarm occurs that ensuing
alarms are ignored. For example, if you enter 5 seconds, alarms
that occur less than 5 seconds after an initial alarm event do not
trigger recording.
After you enter this information, click Save to add the zone to the Zones
directory in the directory tree. The next section describes how to assign
cameras to the zone and configure which events trigger the zone to record.
When creating a zone for the recording of video loss events, be
sure to include an additional three seconds to account for the
maximum lag between the loss of video and the triggering of the
alarm (the system monitors for video loss every 1.5 seconds). For
example, if you want to record five seconds of prealarm video on
the zone, set the prealarm time to eight seconds.
