Abstract
A video recorder includes a sound occurrence detection system to detect a sound occurrence in an area. A detection method can detect the sound occurrence by using the video recorder. The detection method establishes relationships between rotation angles of the video recorder and sound output orientations of a sound source in the area. Furthermore, the detection method determines a rotation angle according to the relationships once the sound occurrence occurs, and rotates the video recorder according to the rotation angle, to record videos and sounds of a sound source that causes the sound occurrence.
