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 includ ed
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.
