Audio

You can set the gain of the audio signals to suit your specific requirements. The live video
image is shown in the window to help you check the audio source. Your changes are effective
immediately.
If you connect via Web browser, you must activate the audio transmission on the 'Live'
functions page. For other connections, the transmission depends on the audio settings of the
respective system.
The audio signals are sent in a separate data stream parallel to the video data, and so increase
the network load. The audio data is encoded according to the selected format and requires
additional bandwidth. If you do not want any audio data to be transmitted, select Off.
