AXIS 212 PTZ - Audio

Audio

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.

Audio Channels

Audio mode

Half-duplexmode 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.
