This Network Camera supports multiple streams with a frame size ranging from 176 x 144 to 2048x
1536�
The denition of multiple streams:
■ Stream 1 & 2: Users can dene the "Region of Interest" (viewing region) and the "Output Frame
Size" (size of the live view window)� It is like selecting a portion of the image captured by sensor
to display only the selection portion� For example, a camera may capture a scene where half of
the screen is the sky, and the other half a parking lot� You may then select the parking lot as the
region of interest, and thus save video size and networking bandwidth�
■ Stream 3: Stream 3 does not support the "Region of Interest" conguration.
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 streams 1� 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 the
vehicles� The blue sky is of little value for the surveillance purpose�
