Audio

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 is used for encoding only in the Axis product. For decoding, no 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 denes 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.
