Stream settings
This Network Camera supports multiple streams with frame sizes ranging from 176 x 144 to 2048 x 1536.
The definition of multiple streams:
■Stream 1: Users can define 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 1600 x 1200.
■Stream 3: The default frame size for Stream 2 is set to the 176 x 144.
■Stream 4: This stream does not support window cropping.
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 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.
