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 3 key regions of a scene to transmit through separate streams for
targeted preview and recording.
By using Milesight 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.

Note: You can set a low bit rate. For example, you can set a bit rate with 512Kbps and a resolution with 1080P, then
you can see the image quality of ROI is more clear and fluent than the other region.
