demand.
2) Click More to configure the pre-record, post-record time, expired time, redundant record/capture
and whether you want to record audio.
•
Pre-record: The time you set to record before the scheduled time or event. For example, when an
alarm triggered the recording at 10:00, if you set the pre-record time as 5 seconds, the camera
records it at 9:59:55.
•
Post-record: The time you set to record after the event or the scheduled time. For example, when
an alarm triggered the recording ends at 11:00, if you set the post-record time as 5 seconds, it
records till 11:00:05.
•
Expired Time: The expired time is the longest time for a record file to be kept in the HDD, if the
deadline is reached, the file will be deleted. You can set the expired time to 0, and then the file
will not be deleted. The actual keeping time for the file should be determined by the capacity of
the HDD.
•
Redundant Record/ Capture: Enabling redundant record or capture means you save the record
and captured picture in the redundant HDD. See Chapter 5.8 Configuring Redundant Record/
Capture.
•
Record Audio: Choose "yes" to record the sound, "no" to record the image without sound.
