Axis 26926r2 Manuale Utente

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.

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. 

Check this box to enable audio in the AXIS 212 PTZ.

Audio mode
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.
