Audio Settings

The AXIS 211M 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 the basic
audio settings for the AXIS 211M,
such as setting the communication
mode and adjusting the sound levels
in the microphone and speakers
connected to the camera.
Note:
The speakers connected to the audio out-
put must have a built-in amplifier, e.g. PC speakers.

Audio Channels - Audio mode

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 finished, 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 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 211M 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.
