Abstract
A camera system includes: a camera configured to capture an image of a surveillance area; a microphone array which includes at least one microphone; and at least one processor configured to implement: a video processor which designates at least one subject in the image as a target; a beam-former which calculates a rotation angle of the microphone array based on a location of the subject; and a driving controller which rotates the microphone array toward the subject based on the rotation angle of the microphone array, wherein the beam-forming unit further performs signal processing on an audio input signal received through the microphone array rotated toward the subject and outputs an audio output signal corresponding to the audio input signal.
