The Stream Type, Resolution, Bitrate Type and Video Quality are not configurable for the Main
Stream (Event) of the IP Camera.

Max. Bitrate Mode: Set the mode to General or Custom (32-6144Kbps).
Max Bitrate (Kbps): Select or customize the maximum bit rate for recording.
Max. Bitrate Range Recommended: A recommended max. bit rate range is provided for reference.
Max. Average Bitrate (Kbps): Set the max. average bit rate which refers to the average amount of
data transferred per unit of time.
The resolution of 960 × 1080 (1080P Lite) is avaiable when the 1080P Lite is enabled in the
Record>Advanced Settings interface (refer to Chapter5.11 Configuring 1080P Lite).
Please refer to the Appendix-Specifications for the supported resolutions of different models.
3. Check the checkbox of Enable H.264+ to enable this function. Enabling it helps to ensure the high video
quality with a lowered bitrate.
After enabling the H.264+, the Max. Bitrate Mode, Max. Bitrate(Kbps) and Max. Bitrate Range
Recommend are not configurable.
The H.264+ can not be used with the SVC at the same time.
For the connnected IP camera, the H.264+ should be supported by the camera and added to the DVR
with the HIKVISION protocol.
You should reboot the device to activate the new settings after enabling the H.264+.

• 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 time for keeping the record files in the HDDs, once exceeded, the files will be
deleted. The files will be saved permanently if the value is set as 0. The actual keeping time for the files
should be determined by the capacity of the HDDs.

Chapter 5.8 Configuring Redundant Recording.
• Record Audio: Enable this feature to record the sound and disable it to record the video without sound.
