What this tab is for
On the ROI tab, you can draw a Region of Interest (ROI). ROI encoding helps to discriminate
the ROI and background information in video compression, which means, the technology
assigns more encoding resources to the region of interest. This increases the quality of the
ROI, whereas the background information is less focused. Note that the ROI function varies
per camera model.
Region types
You can configure Fixed Region settings and Dynamic Region settings.
● Fixed Region: Using fixed region encoding you can configure an area manually. You can
select an image quality enhancing level and also name the ROI area.
● Dynamic Region: The region with motion is automatically calculated.
