Applications > Audio detection
Audio detection, along with video motion detection, is applicable in the following scenarios:
1� Detection of activities not covered by camera view, e�g�, a loud input by gun shots or breaking a
door/window.
2� A usually noisy environment, such as a factory, suddenly becomes quiet due to a breakdown of
machines�
3� A PTZ camera can be directed to turn to a preset point by the occurrence of audio events�
4� Dark environments where video motion detection may not function well�
The red circles indicate where the audio alarms can be triggered when breaching or falling below
the preset threshold�
How to congure Audio detection:
1� Once the Audio detection window is opened, the current sound input will be interactively
indicated by a uctuating yellow wave diagram.
2� Use a mouse click to drag the Alarm level tab to a preferred location on the slide bar�
3. Select the “Enable audio detection“ checkbox and click Save to enable the feature.
1. Note that the volume numbers (0~100) on the side of wave diagram does not represent decibel
(dB). Sound intensity level has already been mapped to preset values. You can, however, use
the real-world inputs at your installation site that are shown on the wave diagram to congure
an alarm level.
2. To configure this feature, you must not mute the audio in Configuration > Media > Audio.
The default of the camera can be muted due to the lack of an internal microphone. An external
microphone is provided by users.
NOTE:
