9.4.10Audio

Select the microphone or line-in connector as the Audio input or switch it off. Adust the Input volume with the slider. Switch the Audio output On or Off.

Select G.711 or L16 as the audio Recording format. The default value is G.711. Select L16 if you want better audio quality with higher sampling rates. This requires approximately eight times the G.711 bandwith.

Note:

The audio signals are sent in a separate data stream parallel to the video data, and so increase the network load. The audio data requires an additional bandwidth of approximately

80 kbps to 640 Kbps, depending on type of audio compression selected, for each connection. If you do not want any audio data to be transmitted, select Off.
