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
A m ulti-connector cable (available from Axis; Mu lti-Connector Cable (sold separately)) is required when connecting external
audio equipment to the Axis product.
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 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 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 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.
Encoding - Select dig
ital audio encoding format.
• AAC requires a license for both encoding and decoding. AAC is the least complicated a nd 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 times per second the sound is sampled. A higher sample rate will provide better audio quality, but
also requires a greater bandwidth.
