Stream settings
This Network Camera supports multiple streams with frame sizes ranging from 640 x 360 to 2560 x
1440 pixels
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 2560
x 1440.
■ Stream 3: The default frame size for Stream 3 is set to the 640 x 360. Only Stream 3 supports
ePTZ (as well as digital zoom in/out), and a configurable Viewing Window. Users can define the
"Region of Interest" (viewing region) and the "Output Frame Size" (size of the live view window).
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.
