Video and Audio

Audio Settings

The audio functionality for each video stream is enabled under Video & Audio > Video Stream > Audio.

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 — 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 buttons must both be active, see AMC Audio Controls, on page 13.

Simplex — 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.

Audio Input

An external microphone or a line source can be connected to the 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.

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.

The 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 48 V phantom power, you need an external power supply and a balanced-unbalanced converter (audio transformer) in between.

Use the Input gain to 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.

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.

G711 is an unlicensed standard codec that is useful when integrating audio into a VoIP system

G726 is an unlicensed speech codec that is most commonly used within the security industry.

The Sample rate defines the number of times per second the sound is sampled. A higher sample rate will provide better audio quality, but also requires a greater bandwidth.
