3.6.7 Pre-Alarm Recording
This item is used to set the recording duration of pre-alarm video. The
pre-alarm recording function aims to allow the user to view a complete event
video. What user can view is not only the video recorded after the alarm is
triggered, but also the video recorded few seconds before the alarm is
triggered.
When an event is triggered while normal recording is in effect, the unit will
start copying the pre-alarm and the post-alarm video to the event video. The
pre-alarm duration can be set from 0~30 seconds.
The quality of the pre-alarm video is the same as the quality setting for normal
record video; and the quality of the post-alarm video is the same as the
quality setting for event record video.
