Stream settings
This Network Camera supports multiple streams with frame sizes ranging from 176 x 144 to 2560 x
1920. (in 5 Megapixels frame size)
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: Users can define the "Region of Interest" (viewing region) and the "Output Frame size"
(size of the live view window).
■ Stream 3: A separately-coinfigured viewing window is not available for stream #3.
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 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.
