< Pre-Alarm Recording >
This item is used to set the recording duration of pre-alarm video. The pre-alarm recording
function aims to allow users to view a complete event video. What users 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.
< Circular Recording >
Users can choose to record video in circular mode or in linear mode. If circular mode is
selected, the DVR will stores new video into the HDD spaces while overwrite the oldest
recorded video. Alternatively, if linear mode is selected, the DVR will stop recording when
the HDD is full. In the meantime, the internal buzzer will start beeping and a message will
be shown on the screen informing 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 UP / DOWN keys.
< Audio Recording >
This item allows users to enable / disable Audio recording function of the unit. When it’s set
to <On>, audio input is recorded and saved with the video. When it’s set to <Off>, audio is
ignored.
