The monitor image is recorded automatically when an

stop when an alarm occurs. If the unit is already
recording then the recording quality does not change for
alarm recording. Set the options for alarm recording in
the Alarm record menu.

3.2.1 Pre-alarm recording

A buffer is used to pre-capture video for
recording images just before an alarm is triggered.
Pre-alarm recording only occurs if the unit is not already
recording during the pre-alarm period. The recording
quality in the pre-alarm period is the same as the
recording quality before the alarm occurs. If the
recorder is not recording before the alarm occurs, the
recording quality in the pre-alarm period is the same as
normal recording quality.
