The device interface
• Client stream information: Turn on to show dynamic information about the video stream used by the browser that
shows the live video stream. The bitrate information differs from the information shown in a text overlay, because of
different information sources. The bitrate in the client stream information is the bitrate of the last second, and it
comes from the encoding driver of the device. The bitrate in the overlay is the average bitrate of the last 5 seconds,
and it comes from the browser. Both values cover only the raw video stream and not the additional bandwidth
generated when it's transported over the network through UDP/TCP/HTTP.
• Adaptive stream: Turn on to adapt the image resolution to the viewing client's actual display resolution, to improve
the user experience and help prevent a possible overload of the client's hardware. The adaptive stream is only
applied when you view the live video stream in the web interface in a browser. When adaptive stream is turned on,
the maximum frame rate is 30 fps. If you take a snapshot while adaptive stream is turned on, it will use the image
resolution selected by the adaptive stream.
