This Network Camera supports multiple streams with a frame size ranging from 176 x 144 to 2048x 

1536�

The definition of multiple streams:

■ Stream 1 & 2: Users can define 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" configuration.  

Click 

Viewing Window to open the viewing region settings page. On this page, you can configure 

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�
