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.
