Video ROI Encoding
It is possible to configure Region of Interest settings for three (CB-6204) or four (CB-6208) H.264
streams on the
Video ROI Encoding
screen. The image displayed within the ROI box can be displayed
with a higher bit rate and quality than the image outside of the box. Overall bit rate is not affected
by selecting Regions of Interest. Enhancing the video where the quality is very important consumes
more bandwidth, but enables lowering image quality and bandwidth consumption on less important
zones in the scene.
