Audio Input
Note
When used in an outdoor enclosure, the internal microphone on this Axis product cannot be used.
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.
