Configuring Audio Detection
The audio detection feature detects audio changes in the camera scene that can generate
events and corresponding actions.

Parameter Function
Enable Input
Abnormal
Check to enable the audio input abnormal function. This detects if the
audio input changes from the "normal" audio that is typically generated
at the camera site.
Enable Intensity
Change
Check to enable the audio intensity change function. This detects if the
audio intensity changes, meaning the volume level becomes stronger
than the typical level.
Sensitivity
Set the Sensitivity level from 1 to 100 for the audio detection. Sensitivity
refers to the audio recognition sensitivity (as a percentage). Moving the
Sensitivity slider to a higher sensitivity setting increases the audio
detection sensitivity which will detect more events.
Threshold
Set the Threshold level from 1 to 100 for the audio detection.
Threshold is the intensity change threshold, or the amount of audio
required to trigger an event notification. The smaller the Threshold
value, the more events will be detected.
Audio Detection
Graph
The best way to configure audio detection is to experiment with the
sensitivity and threshold settings while someone is generating sound
in front of the camera. Use this graph to compare the audio that is
generated to the Threshold line displayed in the graph.
