2. Encoding Parameters Setting for Recording
1) Select Record tab page to configure. You can configure the stream type, the resolution, and other
parameters on your demand.
• Pre-record: The 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 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
not be deleted. The actual keeping time for the file should be determined by the capacity of the
HDD.
• Redundant Record: Enabling redundant record means you save the record in the redundant HDD.
See Chapter Configuring Redundant Recording.
• Record Audio: Check the checkbox to enable or disable audio recording.
2) Click Apply to save the settings.
Note: The redundant record is to decide whether you want the camera to save the record files in the
redundant HDD. You must configure the redundant HDD in HDD settings. For detailed information, see
