Audio Settings

The AXIS 211W can transmit audio to other clients using a connected
external microphone or the internal microphone and can play audio
received from other clients via connected speakers. This section
describes how to configure basic audio settings for the AXIS 211W, e.g.
set the communication mode and adjust the sound levels in the
microphone and speakers connected to the camera.
Note:
The speakers connected to the audio output must have a built-in amplifier, e.g. PC
speakers.

Check this box option to enable
audio in the AXIS 211W.

Audio Channels

Full duplex mode is simultaneous
two-way audio where you can
transmit and receive audio at the
same time.
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 done 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. 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 211W to web clients.
It will not receive audio from any other web client. This can be used in remote monitoring, and web attractions
to provide live audio, and 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.

Audio Input

Audio from a connected microphone or a line source can be connected to the Audio in connector of the AXIS
211W. The audio source must be set to Microphone or Line depending on the connected device.
Note:
To prevent unauthorized listening, the internal microphone can be disabled by inserting a plug in the Audio in connector.
