1. RECORD DURATION
2. PRE-RECORD
Record duration determines the amount of time
the DVR records after the initial motion or alarm
detection. The user may choose from 0, 20, 40,
60, 80, 100, 120, 180 and 240 seconds. Zero
seconds continues to record until the recording is
stopped manually. The default duration is 60
seconds.
The DVR keeps at all times 140 fields of recording
in its buffer in order to compensate for events that
happened
prior to the initial motion or alarm
detection. When motion or alarm is triggered, the
buffer is divided proportionately according to the
camera number and added in front of the data
when motion or alarm recording starts.
