Circular Recording
Users can choose to record videos in circular mode or in linear mode. If
circular mode is selected, the NVR will store new videos into the HDD spaces
while overwriting the oldest recorded videos. 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 at the
status bar to inform users that the disk is full.
From the Record setup menu, set <Circular Recording> to <ON>/<OFF> to
enable or disable circular recording mode.
