[VORTEX Camera] Detection > Audio detection

Audio capture feature in VORTEX devices serves as a valuable tool in surveillance, enhancing crime detection, protection, and forensic investigation. It provides essential context, alerts security teams to out-of-view activity, and proves valuable in situations where video surveillance falls short, such as low-light conditions.

Audio 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. Environment where video surveillance falls short, such as low-light conditions.

How to configure Audio detection:

1. Drag the bar to enable audio detection, and click save
2. After save, the current sound input will be interactively indicated by a fluctuating wave diagram.
3. Use a mouse click to drag the Alarm level tab to a preferred location on the slide bar, and save again

NOTE:

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 configure an alarm level.
2. To configure this feature, you must not mute the audio in Audio settings. The default of the camera can be muted due to the lack of an internal microphone. An external microphone is provided by users.

IMPORTANT NOTE: Audio detection is only available for VORTEX cameras.
