 Pre-record: The time you set to start recording before the scheduled time or the event.
For example, if an alarm triggers recording at 10:00, and the pre-record time is set as 5

The pre-record time can be configured as No Pre-record, 5 s, 10 s, 15 s, 20 s, 25 s, 30 s or
not limited.
The pre-record time changes according to the video bitrate.
 Post-record: The time you set to stop recording after the scheduled time or the event.
For example, if an alarm triggered recording ends at 11:00, and the post-record time is

The Post-record time can be configured as 5 s, 10 s, 30 s, 1 min, 2 min, 5 min or 10 min.
