Set the video codec data flows in the Services / Phone / Video menu for calls
and in the Services / Streaming / RTSP menu for streaming. The set bandwidth
represents the value that the codec has to approach on a long-time average. The
data flows can vary depending on the scene to be scanned.
The measured data flow values correspond to the test view of a person standing
in front of the intercom.
