AAC

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
.
