6.4.3  Configuring ROI Encoding 
Note: Only 4-series of cameras and version above supports the function. 
ROI  stands  for  the  region  of  interest.  And  the  ROI  encoding  enables  you  to 
discriminate the ROI and background information in compression, that is to say, the 
technology assigns more encoding resource to the region of interest to increase the 
quality of the ROI whereas the background information is less focused.   
Steps:   
1.  Enter the ROI settings interface 
Configuration > Advanced Configuration > Video / Audio >ROI 
2.  Draw the region of interest on the image. There are four regions can be drawn. 
3.  Choose the stream type to set the ROI encoding. 
4.  Choose the ROI type. 
There are two options for ROI encoding, the fixed region  encoding and the 
dynamic tracking. 
  The fixed region encoding is the ROI encoding for the manually 
configured area. And you can choose the Image Quality Enhancing level for 
ROI encoding, and you can also name the ROI area. 
  And  the  dynamic  tracking  refers  to  the  ROI  defined  by 
intelligent analysis such as human face detection. You can choose the Image 
Quality Enhancing level for the ROI encoding.
