Pre-Alarm Recording; Circular Recording - D-Link DNR-2060-08P User Manual

Section 4: Advanced Configuration
This options enables the setting of a recording duration before an alarm trigger is received.
The pre-alarm recording function aims to allow users to playback video of a complete event.
This enables you to playback video recorded from immediately 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 to 70 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.
You can choose to record video in either a circular mode or in a linear mode. If circular mode
is selected,the NVR will store new video overwriting the oldest recordings.
Alternatively, if linear mode is selected, the NVR will stop recording when the HDD is full. In
the meantime, the internal buzzer will start beeping and an alert icon will be shown on the
status bar to inform users that the disk is full.
From the Record setup menu, move the cursor to Circular Recording and press ENTER, then
select ON/OFF using the UP/DOWN keys.
