ROI encoding of an image
This feature helps you to optimize image bandwidth and storage. You can select
an important area of detail or ROI (Region of interest) in a stream, such as a
number plate or face. The ROI area will have a higher quality image and the non-
ROI areas will have a lower image quality thereby saving bandwidth.
You can define up to eight ROIs.
To define an ROI:
1. In the Video/Audio folder (1), click the ROI tab (2) to open its window.
2. Using the PTZ panel (3), move the lens to the desired location.
3. Select the stream type (4): main stream or substream.
4. Enable Fixed Region (5). This lets you manually configure the image quality
enhancement level as well as name the region.
5. Select the region number and enhancement level. Enter the region’s name.
6. Draw an area in the image.
