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
