AXIS P3367-VE Network Camera
Video and Audio
To set the audio mode, go to
Video & Audio > Audio Settings
and select the desired mode from the
Audio mode
drop-down list.
Audio Input
An external microphone or a line source can be connected to the Audio-in connector. Configure the audio input settings under
Video
& Audio
>
Audio Settings
.
Note
If using unbalanced Line in a mono contact must be used. Signal on tip and ground on sleeve.
Select
Microphone
to use an external microphone or
Line
to use a Line in device, e.g. an audio mixer for multiple microphones
or a microphone with a built-in amplifier, as audio source.
The
Microphone power
option provides DC power for an external microphone.
To use a professional microphone requiring 48V phantom power, you need an external power supply and a balanced-unbalanced
converter (audio transformer) in between.
Use the
Input gain
to control the volume of the audio input. If the sound is too low, choose a higher dB value, to amplify the
sound. If the sound is too high, choose a lower dB value. 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.
Use the
Encoding
option to 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
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.
Note
The
Sample rate
defines 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.
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.
For more information about these settings, please see the online help
.
Audio Output
An external speaker can be connected to the Audio-out connector (an active speaker with built-in amplifier is required for this). The
output can be connected to another amplifier with speakers. A stereo connector must be used for the audio out.
Configure the audio output settings under
Video & Audio
>
Audio Settings
.
Output gain -
Control the volume of the line audio output. If the sound is too low, choose a higher dB value. If the sound is
too high, choose a lower dB value.
