 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 camera 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.
Note:
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 camera 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.
 Stream Type: You can select the stream type for recording; Main Stream and Sub-stream
are selectable. If you select Sub-stream, you can record for a longer time with the same
storage capacity.
 Overwrite: If you enable his function and the HDD is full, the new record files overwrite
the oldest record files automatically.
Note:
The Pre-record and Post-record parameters vary depending on different camera models.
4. Click OK to save the advanced setting.

 Normal: If you select Continuous, the video will be recorded automatically according to
the time of the schedule.
 Record Triggered by Motion Detection: If you select Motion, the video will be recorded
when the motion is detected. Besides configuring the recording schedule, you have to
set the motion detection area and check the checkbox of Trigger Channel in the Linkage
Method of Motion Detection settings interface. For detailed information, refer to
Section 5.2.1 Configuring Motion Detection.
 Record Triggered by Alarm: If you select Alarm, the video will be recorded when the
alarm is triggered via the external alarm input channels. Besides configuring the
recording schedule, you have to set the Alarm Type and check the checkbox of Trigger
Channel in the Linkage Method of Alarm Input settings interface. For detailed
information, refer to Section 5.2.3 Configuring Alarm Input.
