Video and Audio

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

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

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.

Note

If recording audio to edge storage, such as an SD card or network share, use AAC encoding.

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.

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.

For more information about these settings, please see the online help .

Audio Output

An external speaker can be connected to the Audio-out connector (a built-in amplifier is required for this). The output can be connected to another amplifier with speakers. A stereo connector must be used for the audio out.

Configure the audio output settings under Video & Audio > Audio Settings.

Note

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

Output gain - Control the volume (dB Full Scale) of the line audio output. If the sound is too low, choose a higher dB. If the sound is too high, choose a lower dB.

Audio Clips

An audio clip is a sound file that can be played when events occur or directly from the Live View page. The audio clip must first be uploaded to the Axis product or recorded by a microphone connected to the product.
