ROI
Region of interest(often abbreviate ROI), is a selected subset of samples within a dataset identified
for a particular purpose. Users can select up to 8 key regions of a scene to transmit through
separate streams for targeted preview and recording.
By using ROI technology, more than 50% of bit rate can be saved and therefore less bandwidth
demanded and the storage usage reduced. So according to this, you can set a small bit rate for high
resolution.
