Audio

This section describes how to configure the basic audio settings for the AXIS 213 PTZ such as setting the
communication mode and adjusting the sound levels in the microphone and speaker connected to the
connection module.

Audio - Basic

Enable Audio
Enable audio transmission to and from the AXIS 213 PTZ using the connection module, which is an
optional accessory. See AUDIO IN/OUT, on page 35 for more information.
Audio Channels
There are two mono audio channels between the AXIS 213 PTZ and other clients, one for receiving audio
and one for transmitting audio. Each audio channel can be turned on or off, which means that there are
four audio mode options that can be used.
Full-duplex mode means that you can transmit and receive audio (talk and listen) at the same time, without
having to use any of the controls. This is just like having a telephone conversation. The only controls you
may wish to use in this mode are the mute buttons - to turn the sound off, and the sliders - to adjust the
input/output volume levels. This mode requires that the client PC has a sound card with support for
full-duplex audio. If your available bandwidth is 0.2 Mbit/s or less, it is recommended that you use
half-duplex mode instead.
Half-duplex mode also 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 help of 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. You now 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 12. It is also
possible to configure the Push-to-talk button so that it toggles between speaking and listening modes.
Half-Duplex mode is best if you only have limited bandwidth available.
When you select Simplex - AXIS 213 PTZ speaker only mode, the speaker connected to the AXIS 213
PTZ's connection module plays audio, but no audio is transmitted from the AXIS 213 PTZ to other web
clients. This could be used to provide spoken instructions to a person seen in the network camera. This
mode requires you to use the push to talk button.
Simplex - AXIS 213 PTZ microphone only mode transmits audio from the microphone connected to the
AXIS 213 PTZ's connection module to any web clients. It does 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.
