Audio Modes
The Axis product supports the following audio modes:
• Full duplex – Simultaneous two-way audio allowing the Axis product to transmit and receive audio at the same time.
There is no echo cancellation; if feedback loops appear, try moving the microphone or the speaker.
• Half-duplex – Audio can be transmitted to and from the Axis product but only in one direction at a time. To transmit
audio using the Live View page, use the Talk and Listen buttons, see AMC Audio Controls on page 13.
• Simplex – Network Camera speaker only - Audio is transmitted from a client to the Axis product and can be played by
a speaker connected to the product. To transmit audio using the Live View page, the Talk and Microphone on buttons
must both be active, see AMC Audio Controls on page 13.
• Simplex – Network Camera microphone only - Audio captured by the product microphone is transmitted from the
Axis product to one or more clients.
To set the audio mode, go to Video & Audio > Audio Settings and select the desired mode from the Audio mode drop-down list.

Note
If using unbalanced Line in a mono contact must be used. Signal on tip and ground on sleeve.
Select Microphone to use an external microphone or Line to use a Line in device, e.g. an audio mixer for multiple microphones
or a microphone with a built-in amplifier, as audio source.
Select the +30 dB microphone boost option to amplify the signal of the external microphone connected to the Axis product.
Microphone boost option is useful when a microphone's volume is too low and you want to increase it. This option is not available
when the Line source is selected
The Microphone power option provides DC power for an external microphone.
Use the Input gain to control the volume of the audio input. If the sound is too low, choose a higher dB value, to amplify the
sound. If the sound is too high, choose a lower dB value. The Level bar gives a visual representation of the audio signal level in dB
relative to the full-scale input level.
• Green — the signal is at a good level.
• Yellow — the signal is becoming distorted.
• Red — the signal is distorted.
Use the Encoding option to select digital audio encoding format.
• AAC requires a license for both encoding and decoding. AAC is the least complicated and most widely used codec. If
achieving the best possible audio quality is a priority, AAC is the recommended codec to use. An AAC license is included
in the Axis product.
