VIVOTEK FD8164 User Manual

 

 

Advanced Mode

   

This Network Camera supports multiple streams with frame sizes ranging from 176 x 144 to 1920 x 

1080 pixels (FD8164 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 1280 x 720, 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.
