This Network Camera supports multiple streams with a frame size ranging from 176 x 144 to 1280
x 800�
The denition of multiple streams:
■ Stream 1: Users can dene 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 the sensor
to display only the selected 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 2: Stream 2 does not support the "Region of Interest" conguration.
Click Viewing Window to open the viewing region settings page. On this page, you can congure
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
vehicles� The blue sky is of little value for the surveillance purpose�
Please follow the steps below to set up those settings for a stream:
1� Select a stream for which you want to set up the viewing region�
2� Select a Region of Interest from the drop-down list. The oating frame, the same as the one

with your mouse�
3� Choose a proper Output Frame Size from the drop-down list according to the size of your
monitoring device�
