a microphone with a built-in amplifier.
Microphone power - Microphone power should only be used with electric microphones that have no battery and when using the
internal microphone. This setting should not be enabled when using a dynamic or battery powered microphone.
Input gain - Control the volume (dB Full Scale) of the audio input. I f the sound is too low, choose a higher dB. If the sound is too
high, choose a lower dB. The Level bar gives a visual representation of the audio signal in dB Full Scale.
• Green — the signal is at a good level.
• Yellow — the signal is becoming distorted.
• Red — The signal is distorted
Encoding - Select digital audio encoding format.
• 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. A AC is the least complicated and most widely used codec. If
achieving the best possible audio quality is a priority, AAC is the rec
ommended codec to use. An AAC license is included
in the Axis product.
Sample rate - The number of times per second the sound is sampled. A higher sam ple rate will provide bette r 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 a udio quality. A lower bit
rate may have latency or delay, but will require less bandwidth.
