Sound classification
The type of sound detected while the camera is capturing an image can be classified and created as a sound
classification event. When you complete the setting, click the [Apply] button at the bottom of the page.
The setting on the sound classification event applies to [Sound classification] on the [Event]>[Event setup] pages
equally.

Configuration

Note
If [Line] is set for [Source] in [Video & Audio]>[Audio setup]>[Audio in], the sound
classification function does not operate.
Enable sound classification
To use the sound classification event, select [Enable sound classification].
Noise filter
To use the noise removal filter, select [Enable]. If the noise from the surrounding
environments is higher than 55dB~65dB, use [Noise filter]. Using the noise reduction
function according to environments reduces original sound so that the sound
classification performance may deteriorate, or a malfunction may occur. If the noise
reduction filter is used in a quiet environment, the sound classification performance
may deteriorate.
Level of classification
Sets the level of audio energy to classify the sound. The level value of input audio
energy is drawn on the area while being renewed periodically from right to left. The
sound classification applies only to audio over the set level. In other words, it is
classified as the sound source only when the energy of the audio input is higher than
the reference line. If the reference line is lowered, there is more target data for the
sound classification, and a higher possibility of false detections. If the reference line
rises, there are less target data for the sound classification and a higher probability of
missing detections. Set it properly according to the surrounding noise level.
Categories
This detects the type of sound and creates an event. The type of sound to detect can
be selected and can be selected repeatedly.
Scream: Triggers an event by detecting a sudden loud sound, including a scream or
shout made by a person such as an adult male, female, or child.
Gunshot: Triggers an event by detecting a gunshot that does not occur repeatedly.
Explosion: Triggers an event by detecting a sudden sound caused by destruction.
Crashing glass: Triggers an event by detecting the sound of breaking glass.
