Real-Time Intruder Detection System Using Sound Localization and Background Subtraction

In this paper, an efficient and real-time intruder detection system, based on the concepts of sound localization and background subtraction, is proposed. The system consists of a camera capable of 180° rotation and a microphone array. The camera turns towards the direction of the source of disturbance by sound localization, based on the Delay of Arrival technique. The system detects the presence of possible intruders in real-time, using background subtraction, and alerts the security center on detection.
