Audio Input

Input sensitivity - Select the microphone sensitivity level (High/Low) depending on the sound level in the monitored area. For

example, if the Axis p roduct is installed in a noisy environment, try setting the input sensitivity to Low.

Input gain - 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 visua l repres entation 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.

Encoding - Select digital audio encoding format.

• AAC 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 recomm ended codec to use. An AAC license

is included in the A xis product.

• G711

• G726

Sample rate - The number of times per second the sound is sam pled. A higher sample rate will provide better a udio quality, but

also requires a greater bandwidth.

Bit rate - Set the required bit rate depending on the selected encoding. A higher bit ra te will give better audio quality. A lower bit

rate may have latency or delay, but will require less bandwidth.
