— Pre-record: The length of 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 length of 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 a recording is kept on the HDD. If the deadline is reached, the le
will be deleted. If you set the expired time to 0, the le will not be deleted. This parameter is usually determined in
consideration of the capacity of the HDD.
— Record Audio: Check the checkbox to enable audio recording.
