18.4 Setting up Pre-Alarm
Recording
The NetVision system can make continuous
short recordings (1 - 300 sec.) during
scheduled alarm-monitoring times, with only
the two most recent being retained at any time
(for each camera). When an alarm is
triggered, this provides a recording of the
scene just before the alarm occurred without
using up a lot of hard drive space. This
pertains to recording that is triggered by
external sensors/inputs, or video motion
detection.
TechTip:
Scheduled (and manual /
instant) recording are not available while
pre-alarm recording is in effect on a
specific camera (i.e., during the scheduled
alarm/monitoring times).
