User’s Manual

5.4.7Pre-Alarm Recording

This item is used to set the duration time of pre-alarm recording video. The pre-alarm recording function aims to give the user the opportunity to view a more complete event video. The user can see the video recorded after the alarm is triggered, and the video recorded ahead the alarm.

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.

5.4.8Circular Recording

The 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 recorded video and stores new video over the HDD spaces. If you choose to record in linear mode instead, the unit stops recording when the HDD is full.

From the Record Setup menu, move the cursor to <Circular Recording> and press ENTER, then select <ON> / <OFF> using UP / DOWN keys.

5.4.9Audio Recording

This item allows the user to enable / disable the Audio recording function of the unit. When set to <ON>, audio input is recorded and saved with the video. When set to <OFF>, audio is ignored. The default setting is <ON>.
