8.4.3 ROI "Region of Interest"
The "Region of Interest (ROI)" function defines areas in the video image which are transmitted at a higher
bitrate than the surrounding areas.
Channel Number: selection of the channel number for adding ROIs.
Draw Area: Depiction of up to three ROI areas per channel (the region number must be changed below for a
new area).
Delete all: Delete all ROI areas in the video image.
Stream Type
Stream Type: ROI can only be used in the Normal Stream (Main Stream).
Fixed Region
Enable: Tick the selection box to enable all areas.
Region no: (1–3): Select the four areas (four areas for each channel).
ROI level (1–3): Using the value "3", will compromise the selected areas the least (and therefore the highest
possible quality will be achieved).
Region Name: Assign a name to the region.
The ROI function only has an effect if the usual video stream setting has a low bit
rate/video quality.
