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 Internet Explorer, or click Home on the camera's admin page. You should
then see the control panel for the AXIS 2191 below the camera image. If no audio controls are
visible, check that you have made the correct setting under External Devices.
Push-To-Talk
Used in Half-Duplex or
Simplex - Talk mode.
The button's own
mode is set in the
camera's admin pages.
Show/Hide Settings
Shows or hides the
slider controls and
level indicators.
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 to turn off
the sound, and the level sliders, to adjust the input/output levels. This mode requires a
full-duplex sound card on your computer. If your available bandwidth is 0.2Mbit/s or less,
it is recommended that you use Half-Duplex mode instead.
Half-Duplex
Half-Duplex mode also sends and receives audio in both directions, but only in one
direction at a time. This means 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 admin tools.
Half-Duplex mode is best if you only have limited bandwidth available.
Level Adjust IN/OUT
Drag sliders to adjust level.
