Stream settings
This Network Camera supports multiple streams with frame sizes ranging from 176 x 144 to
1280x800 (FD8137H series).
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 640 x 360, and the Viewing Window
function is not available for stream 2.
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.
