Installing the Audio Module
❶ Before installing the AXIS 2191 Audio Module, first install your network camera. Refer to the
installation section on page 12. If you intend running the audio module in full-duplex mode, check
that the sound card on your computer supports this.
❻ Connect power
to the audio module.
❷ If using an external microphone, connect it to
the socket provided. To use an alternative input
device, (e.g. CD-player or radio) connect it to
Line-In on the terminal block.
❹ Connect a loudspeaker to the 3.5mm socket (amplified speakers
only), or to Out on the terminal block (speakers with no amplifica-
tion). Other devices (including headphones) are connected to the
terminal block.
❼ Check that the power indicators on both the audio module and the
camera are lit. Note that the power LED will blink during power-up.
❺ Using the supplied cable, connect the
audio module’s serial port to the network
camera’s serial port.
❸ Set the selector switch
to Ext to use an external
microphone or device.
Otherwise, set to Int to use
the internal microphone.
❽ Using a screwdriver,
adjust the Volume In con-
trol so that the Level In
LED occasionally shows
yellow, but not red.
❾ To verify the connection to the AXIS 2191,
start Internet Explorer and enter the IP address
of the network camera in the location/address
field, e.g. 171.1.2.200, as shown here. Configure
the audio module from the camera’s adminis-
tration pages, as described in the following
section.
