Audio Channels
Select the type of audio transmission from the Audio mode: drop-down list (Video & Audio> Audio Settings). The different types are:
Full duplex - Simultaneous two-way audio allowing you to transmit and receive audio (talk and listen) 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 in both directions between the Axis product and the client computer, but only in one
direction at a time. You must actively receive sound using the Talk/Listen button visible in the Live View page (see
Control viewer toolbar
once to switch between speaking and listening. The Talk/Listen mode is configured from the Audio tab in the AMC control panel
(see AXIS Media Control on
Simplex - Network Camera speaker only - Audio is transmitted from the client to the Axis product and played by the speaker
connected to the product. To send audio, the Talk and Microphone buttons in the AMC toolbar must both be enabled. Click either
button to stop audio transmission.
Simplex - Network Camera microphone only - Audio captured by the microphone connected to the Axis product is transmitted from
the product to one or more clients.

Audio Input
An external microphone or a line source can be connected to the product's Audio-in connector. Configure the audio input settings
under Video & Audio > Audio Settings.
Note
The internal microphone is used by default; the external microphone is used when connected. It is possible to disable the
internal microphone by connecting a plug to the mic input.
Source - Select Microphone for an external microphone or Line for a Line in device, e.g. an audio mixer for multiple microphones or
a microphone with a built-in amplifier.
Microphone power - The Enable microphone power option provides DC power for an external microphone. Microphone power should
only be used with microphones that have no battery and when using the internal microphone. This setting should not be enabled
when using a dynamic or battery powered microphone. Microphone power will not harm the microphone; if you are uncertain, try
switching it off and on. To use a professional microphone requiring 48V phantom power, you need an external power supply and a
balanced-unbalanced converter (audio transformer) in between.
Input gain - Control the volume (dB Full Scale) of the audio input. If the sound is too low, choose a higher dB, to amplify the
sound. If the sound is too high, choose a lower dB. 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.
Encoding - 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.
