[Bandwidth Management]
When using H.265 / H.264, it is possible to control the bitrate, which in turn allows the
amount of bandwidth usage to be controlled.

VBR (Variable Bitrate): The quality of the video stream is kept as constant as possible
at the cost of a varying bitrate. The bandwidth is used much more efficiently than a
comparable CBR. You can set a limit to the bit rate by specifying a
Maximal Bit Rate .
Set the image quality to one of the 5 standards: Standard, Fair , Good , Great , and
Excellent .

CBR (Constant Bitrate): CBR is used to achieve a specific bitrate by varying the quality
of the stream. Use the Maximal Bit Rate drop-down list to select a bitrate.

Smart Streaming: When the option is enabled, the bitrates will be automatically reduced
in static scenes, significantly maximizing bandwidth and lowering file size.

You can choose the image quality of Static Scene and Dynamic Scene to one of the
5 standards: Standard , Fair , Good , Great and Excellent . You can even choose the
maximum bitrate to optimize the bandwidth.

Bitrate Reduction Level : The default value is 254 / 300. The bigger the value the
more bitrates can be reduced in static scenes, thus saving the recording size.
Note: To enable Smart Streaming , only supported by GV-FER5700 / 5701 / 12203 and
GV-EFER3700 Series, it is required to use either GV-NVR V8.7.0 or GV-VMS V16.10.3
and later versions. For details, see t.
