Audio stream
In addition to video data, the unit can also send and receive audio signals. The
transmission of audio takes place at the same time as that of the video data in a
separate data stream. Thus it increases the data traffic. The audio data is coded
according to G.711 compression standard and requires an additional bandwidth
of about 80 kBit/s per direction.
