[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 the
technical notice
