This Network Camera supports multiple streams with frame sizes ranging from 176 x 144 to 2048 x 1536
pixels.
The denition of multiple streams:
■ Stream 1: Users can dene the "Region of Interest" (viewing region) and the "Output Frame Size" (size
of the live view window).
■ Stream 2: The default frame size for Stream 2 is set to the 640 x 480.
■ Stream 3: The default frame size for Stream 3 is set to the 2048 x 1536.
Click Viewing Window to open the viewing region settings page. On this page, you can congure the
Region of Interest and the Output Frame Size for a video stream. For example, you can crop only a
portion of the image that is of your interest, and thus save the bandwidth needed to transmit the video
stream. As the picture shown below, the area of your interest in a parking lot should be the vehicles. The
blue sky is of little value for the surveillance purpose.
