Description

Sound source analyzing apparatus The present invention relates to a sound source analysis device, and more specifically, to a sound source analysis device that analyzes a sound source using a plurality of microphones. A camera may be used for monitoring a specific space. Video generated by the camera is transmitted to a server in real-time or periodically, and the user can access the server using their terminal to view the camera footage. Alternatively, the video generated by the camera may be transmitted directly to the user's terminal. Meanwhile, for a surveillance system using cameras, the space must be equipped with lighting. For example, if the surveillance space is not equipped with lighting or if the provided lighting is not functioning, surveillance using cameras may not be performed properly. Microphones can be used to replace cameras. Events in the surveillance space can be detected by analyzing sound using microphones. On the other hand, when a surveillance system is established using microphones, the location where an event occurred may not be easily identified. Therefore, in constructing a surveillance system using a microphone, there is a need for an invention that enables easy identification of the location where an event occurred.
