Configuring ROI Encoding
Purpose:
ROI (Region of Interest) encoding helps to discriminate the ROI and background information in video compression, which
means, the technology assigns more encoding resource to the region of interest, thus to increase the quality of the ROI
whereas the background information is less focused.
NOTE:
ROI function varies by camera model.
