Audio Settings
The AXIS 212 PTZ can transmit audio to clients using either the built-in microphone or a connected external
microphone and can play audio received from clients via a connected speaker.
Note: The speaker connected to the audio output must have a built-in amplifier, e.g. PC speakers.
An example of a network using AXIS 212 PTZ cameras to transmit audio and video across the network.
This section describes how to configure the basic audio settings for the AXIS 212 PTZ, e.g. set the
communication mode and adjust the sound levels in the microphone and speaker connected to the camera.

Audio Channels
Half-duplex mode transmits and receives audio in both directions, but only in one direction at a time. This
means that you must select when to receive or transmit audio with the push-to-talk button. To speak, press and
hold the button (check that the microphone is not muted). When finished speaking, release the button and you
will receive audio from the other end of the connection.
Note that the push-to-talk button is configured from AMC, see AXIS Media Control, on page 9. It is also possible
to configure the push-to-talk button so that it toggles between speaking and listening modes.
When selecting Simplex - Network Camera speaker only mode, the speaker connected to the camera will play
audio, but no audio will be transmitted from the camera to other web clients. This could be used to e.g. provide
spoken instructions to a person seen in the camera. This mode requires you to use the push-to-talk button.
Simplex - Network Camera microphone only mode transmits audio only from the AXIS 212 PTZ to web
clients. It will not receive audio from any other web clients. This can be used in remote monitoring, web
attractions etc., to provide live audio, as well as video, of a monitored situation.
When using half-duplex, the Send the sound from the active client to all other clients option transmits the
audio signal from the client that is talking to all the other clients.
