AXIS 233D - Audio
Audio
The AXIS 233D can transmit audio to other clients by connecting an external microphone
and can play audio received from other clients via a connected speaker.
Audio Settings
This section describes how to configure the basic audio settings for the AXIS 233D, e.g. set
the communication mode and adjust the sound levels in the microphone and speaker
connected to the camera.
Enable Audio - Check this box to enable audio.
Audio Channels
The AXIS 233D has four types of audio transmission. Choose which type best suits your
needs.
Audio mode
• Full duplex mode has simultaneous two-way audio, which means you can talk
and listen 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 speaking, release the button
and you will receive audio from the other end of the connection.
Note: 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 con-
nected 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 instruc
-
tions 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 233D to web clients. It will not receive audio from any other web cli
-
ents. 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.
