• Video Quality: Set the video quality of recording, with six levels configurable.
The Stream Type, Resolution, Bitrate Type, and Video Quality are not configurable for
the Main Stream (Event) of the IP Camera.
• Frame Rate: Set the frame rate of recording.
For HUI Series DVRs, when a 5 MP signal input is connected, the frame rate of the
main stream cannot exceed 12 fps. When a 4 MP signal input is connected, the frame
rate of the main stream cannot exceed 15 fps.
The minimum frame rate for main stream is 1 fps.
• Max. Bitrate Mode: Set the mode to General or Custom.
• 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.

average amount of data transferred per unit of time.
• Video Encoding: You can configure H.264 or H.265 for the main stream
(continuous) of IP and analog cameras. Check the Enable H.264+ or Enable
H.265+ checkbox to enable this function. Enabling it helps to ensure high video
quality with a lowered bitrate.
When the connected IP camera does not support H.265, only H.264 can be seleted for
the main stream (continuous).
The analog and IP cameras support enabling H.264+/H.265+ if the video encoding is
H.264/H.265 for the main stream.
After enabling H.264+ or H.265+, the Bitrate Type, Video Quality, Max. Bitrate Mode,
Max. Bitrate (Kbps), and Max. Bitrate Range Recommend are not configurable.
If H.265+ is enabled, line crossing detection and region entrance detection are not
supported.
For a connnected IP camera, H.264+ or H.265+ must be supported by the camera and
added to the DVR with the HIKVISION protocol.
5. Reboot the device to activate the new settings after enabling H.264+ or H.265+.
6. Click More Settings to configure additional parameters.
