Audio Clips - Axis P3364–LV User Manual

AXIS P3364–LV Network Camera
Video and Audio
To use a professional microphone requiring 48 V 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 (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.
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.
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 product's Audio-out connector (a 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 (dB Full Scale) of the line audio output. If the sound is too low, choose a higher dB. If the
sound is too high, choose a lower dB.

Audio Clips

An audio clip is a sound file that can be played when events occur or directly from the Live View page. The audio clip must first be
uploaded to the Axis product or recorded by a microphone connected to the product.
To add, download, modify or remove audio clips, go to Video & Audio > Audio Clips. For more information see the online help
To configure the Axis product to play audio clips when an event occurs, an action rule must be set up. For more information, see
Events, on page 36.
Note
Audio clips cannot be used if the product's audio functionality is enabled. The audio functionality is enabled on the Audio
tab under Video & Audio > Video Stream.
