Acoustic Inspector, created through Sound Cam Korea's long-term research and development, is an inspection and tracking system optimized for the era of the 4th Industrial Revolution. Through the developed system, data such as abnormal noise and leaks (leakage) occurring in facilities can be stored, classified, predicted, and visualized in the cloud at a low cost to prevent and predict future facility problems and facility safety in advance. there is. We have developed the first system in Korea to objectify acoustic information through the use of multi-channel microphones and beamforming technology. It is used as an abnormal noise diagnostic tester for specific products produced in production facilities. Additionally, by utilizing the technology, an anti-drone system capable of detecting and tracking unmanned aerial vehicles at long distances can be implemented with its own technology.
