Stream settings
This Network Camera supports multiple streams with frame sizes ranging from 176 x 144 to 1280 x
800 pixels.
The denition of multiple streams:
■ Stream 1~3: Users can dene the "Region of Interest" (viewing region) and the "Output Frame
Size" (size of the live view window).
■ Stream 4: The default frame size for Stream 4 is set to the 1280 x 800, 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 congure
the Region of Interest and the Output Frame Size for different streams. 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 the vehicles. The blue sky is of little value for the surveillance purpose.
