Abstract
A device for preventing cables against external damage based on sound source localization comprises a power supply unit, and a sound source sensor unit, a camera unit, a signal processing unit and a wireless communication unit which are electrically connected to the power supply unit. The signal processing unit is connected to the sound source sensor unit, the camera unit and the wireless communication unit. The camera unit is associated with the sound source sensor unit. When the sound source sensor unit recognizes a target signal, the signal processing unit sends a trigger signal to the camera unit, and then the camera unit is triggered to replay a surveillance video to determine whether or not a target really exists. Compared with the prior art, the device has the advantages of being good in safety, high in reliability and the like.
