Video and Audio
• 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 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.
