example, when an alarm triggers 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 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: Enabling redundant record means you save the recording files
in the redundant HDD. See Chapter Configuring Redundant Recording.
