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 default setting is 15
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.

User can choose to record video in circular mode or in linear mode. If you
choose to record in circular mode, then the unit begins to overwrite the oldest

buzzer starts beeping when the HDD is full.

press ENTER, then select <ON> / <OFF> using UP / DOWN keys.
