5.4 ROI
ROI (Region of Interest) encoding helps to discriminate the ROI and background informaon in
video compression. The technology assigns more encoding resource to the region of interest, thus
to increase the quality of the ROI whereas the background informaon is less focused.
5.4.1 Set ROI
ROI (Region of Interest) encoding helps to assign more encoding resource to the region of interest,
thus to increase the quality of the ROI whereas the background
informaon is less focused.
Before You Start
Please check the video coding type. ROI is supported when the video coding type is H.264 or H.
265.
Steps
1.
Go to
Conguraon → Video/Audio → ROI .
2.
Check Enable.
3.
Select Stream Type.
4.
Select Region No. and click
to draw ROI region on the live view.
Note
Select the xed region that needs to be adjusted and drag the mouse to adjust its posion.
5.
Input the Area Name and ROI Level.
6.
Click Save.
Note
The higher the ROI level is, the clearer the image of the detected region is.
7.
Oponal: Select other region No. and repeat the above steps if you need to draw mulple xed
regions.
5.5 Display Info. on Stream
The informaon of the objects (e.g. human, vehicle, etc.) is marked in the video stream. You can
