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.

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

a microphone with a built-in ampliﬁer.

Microphone power - The Enable microphone power option provides DC power for an external m icrophone. Microphone power should

only be used with micropho nes that have no battery and when using the internal microphone. 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 and a

balanced-unbalanced converter (audio transformer) in between.

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 v isual representa tion of the a u dio 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 d

ecoding. 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 better audio quality, but

also requires a gre ater bandwidth.

Bit rate - 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.
