⑤ ROI
ROI is the area of interest setting. Users can set the most concerned and most interested area
in the video screen through this function. IPC will improve the video image quality of the
corresponding area when video encoding, and reduce the encoding quality of other areas, so
as to highlight the image effect in the selected area.
The specific operation steps are as follows:
Step 1: In the main interface, click "Configuration → Events → Ordinary Events →
ROI" to enter the ROI setting interface, as shown in Figure 8-28.
Step 2: 【Region Settings】Move the mouse to the preview screen, hold down the left mouse
button to select the ROI area range, and release the left mouse button to complete the area
drawing. You can also enter the X, Y, W, and H corresponding positions in the corresponding
area to set the area.
Step 3: 【Set "Relative QP value" or "Absolute QP value"】Select "Relative QP value" or
"Absolute QP value" in the corresponding area position and enter the corresponding value.
Step 4: Click "Apply" to complete the ROI setting.
The ROI function depends on the specific model, and the ROI function is only
supported under the H.264 or H.265 code. Other codes do not support the
ROI function at this time.
Click 【Delete】 in the corresponding setting area to delete the corresponding
ROI area.
