AXIS 2191 Installation Guide - DRAFT COPY

Using the Audio Module with Your Camera

Your Audio Module is now configured and ready for use with your network camera. Enter your

camera's IP-address in your browser, or click Home on the Admin page. You should then see the

control panel for the AXIS 2191 below the camera image.

NB. Exactly which controls

will be visible below the

image depends on the audio

mode you are using. For

example, the Push-to-Talk

button will not be visible in

Full Duplex mode. Similarly,

when using Simplex-Listen

mode, only the Volume Slider

and the Speaker mute button

will be shown.

Push-To-Talk

Used in Half Duplex or

Simplex - Talk mode. The

button's own mode is set in

the camera's admin pages.

Using the Different Audio Modes

Full Duplex

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 are the mute checkboxes and the volume sliders, to kill the sound or to

adjust the input/output levels. This mode requires a full duplex sound card on your computer.

Half Duplex

Half Duplex mode also sends and receives audio in both directions, but only in one direction at a

time. This means that you must actively transmit with the help of the Push-to-Talk button. To speak,

press the button (check that the microphone is not muted). When finished speaking, release the

button. You will now be receiving audio from the other end of the connection. Note that the Push-to-

Talk button can be configured for use in two different ways - Toggle or Instant. This is set in the

camera's administration tools.

Simplex - Talk

Simplex - Talk mode means that only the web-client end of the connection can transmit audio (i.e. to

the AXIS 2191). This could be used to e.g. provide spoken instructions to a person seen in the

network camera. This mode also requires you to use the Push-to-Talk button.

Simplex - Listen

Simplex - Listen mode can only receive audio from the AXIS 2191 to the web-client. This can be used

in remote monitoring, web attractions etc., to provide live audio, as well as video, of a monitored

situation.
