 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 seconds, the speed dome starts to record at
9:59:55.
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 set as 5 seconds, the speed dome records until 11:00:05.
The Post-record time can be configured as 5 s, 10 s, 30 s, 1 min, 2 min, 5 min
or 10 min.
The Pre-record and Post-record parameters vary depending on the speed
dome model.
