This Network Camera supports multiple streams with frame sizes ranging from 768 x 144 to 7552 x
1416 pixels.
■ 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 3200 x 600.
■ Stream 3: The default frame size for Stream 3 is set to the 768 x 144
■ Stream 4: The default frame size is 7552 x 1416, and the Viewing Window function is not
available for stream 4.
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.
