9.3  Configuring ROI 
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 according to different camera models. 
Steps: 
1.  Go to Configuration> Device Configuration> Encoding and Storage > ROI.
