Enable H.264+ Mode: check the checkbox to enable. Once enabled, the Max. Bitrate Mode,
Max. Bitrate(Kbps) and Max. Bitrate Range Recommend are not configurable. Enabling it helps

Pre-record: The time you set to record before the scheduled time or event. For example, when an
alarm triggers the recording at 10:00, and if you set the pre-record time as 5 seconds, the camera
records 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, and if you set the post-record time as 5 seconds, it
records till 11:00:05.
•
Expired Time: The expired time is period for a recorded file to be kept in the HDD. When the
deadline is reached, the file will be deleted. If you set the expired time to 0, the file will not be
