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

Amulti-connector cable (available from Axis; Multi-Connector Cable (sold separately)) is required when connecting external audio equipment to the Axis product.

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 - Microphone power should only be used with electric 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.

Input gain - Control the volume (dB Full Scale) of the audio input. If the sound is too low, choose a higher dB. If the sound is too high, choose a lower dB. The Level bar gives a visual representation of the audio signal in dB Full Scale.

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.

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.

ACC 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.

Sample rate - 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.

Bit rate - Set the required bit rate depending on the selected encoding. A higher bit rate will give better audio quality. A lower bit rate may have latency or delay, but will require less bandwidth.
