[Bandwidth Management]
When using the H.264 codec, it is possible to configure the bitrate settings to control
bandwidth usage.
 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 much more efficiently used than a
comparable CBR. Set the image quality to one of the 5 standards: Standard, Fair, Good,
Great and Excellent.
 Maximal Bit Rate: When the system bitrate exceeds the specified Maximal Bit Rate, the
system will automatically lower its bitrate so as not to exceed it. Select one of the bitrates
from the drop-down list or select Auto if you do not want to enable this function. The
default value is 6 MB
 CBR (Constant Bitrate): CBR is used to achieve a specific bitrate by varying the quality
of the stream. The bitrates available for selection depend on the image resolution.
