Audio Input

An external microphone or a line source can be connected to the product’s Audio-in connector. Conﬁgure the audio input settings

under Video & Audio > Audio Settings.

Note

The internal microphone on this Axis p roduct cannot be used.

Source - Select Microphone for an external microphone or Line for a Line in device, e.g. a n audio mixer for multiple microphones or

a microphone with a built-in ampliﬁer.

Microphone power - The E nable microphone power option provides DC power for an external microphone. Microphone power

should only be used with microphones that have no battery. This setting should not be enabled when using a dynamic or battery

powered microphone. Microphone power will not harm the microphone; if you are uncertain, try switching it off and on. To use a

professional microphone requiring 48V phantom power, you need an external power supply a nd a balanced-unbalanced converter

(audio transformer) in b etw een.

Input gain - Control the volume (dB Full Scale) of the audio input. If the sound is too low, choose a higher dB, to a mplify the

sound. If the sound is too high, choose a lower dB. The Level bar gives a visual r epresentation 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. 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

• G726

Sample rate - The number of tim es per second the sound is sampled. A higher sample rate will provide b ette 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 wil l give better audio quality. A lower bit

rate may have latency or delay, but w

ill require less bandwidth.

sou

nd is too high, choose a lower dB.
