If you select VBR, DVR will adjust the actual bit rate according to the video movement. When there is
not much movement, DVR will use low bit rate, while there is much movement, DVR will use high bit rate.
In this case, DVR can save HDD usage and network bandwidth.
If you select CBR, DVR will use the fixed bit rate to compress image.
