Configuring Video Settings
This section describes how to configure camera properties (picture, exposure, white
balance, day and night, and lighting compensation) and video streaming properties
(format, resolution, frame rate, bit rate, and I-frame interval).

The page is divided into two sections: Main Stream and Sub Stream. In the Sub Stream
section, two sub streams are configurable: Sub Stream 1 and Sub Stream 2. To enable a
sub stream, select one of the sub streams, and then select the Enable check box.
For each record type (General, Motion, Alarm), you can configure the encoding format,
resolution, frame rate, bit rate, and I-frame interval settings. You can also apply a
custom watermark to the main stream.
Encode Mode
In the Format box, select H.264B, H.264, H.264H, MJPEG, or H.265.
H.264:
Main Profile. Uses less bandwidth than Baseline Profile at the same quality.
H.264B:
Baseline Profile. Uses up to 50% less bandwidth than MPEG4 and up to 80%
less than MJPEG. Higher compression and lower quality than H.264.
H.264H:
High Profile. Uses less bandwidth than Main Profile at the same quality.
Lower compression and higher quality than H.264.
MJPEG:
Uses the most bandwidth but produces excellent image quality with access
to every image in the stream.
H.265:
High Efficiency Video Coding. Supports 4K resolution. Twice as efficient as H.264.
Smart Codec
Set Smart Codec to ON or OFF.
By taking reference frames and applying them to refreshed frames, Smart Codec
eliminates the need to transmit data for an unchanged image or parts of the image
where there is no movement. Used together with H.264, Smart Codec can lead to
