Abstract
An automated security surveillance system determines a location of a possible disturbance and adjusts its cameras to record video footage of the disturbance. In one embodiment, a disturbance can be determined by recording audio of the nearby area. A system, coupled to a camera, may include an arrangement of four audio sensors recording audio of the nearby area to produce independent outputs. The system further may include a processing module configured to determine an angle and distance of an audio source relative to a location of the arrangement of the four audio sensors. The system can then adjust the camera by rotation along an azimuth or elevation angle and adjusting the zoom level to record video of the audio source. Through use of the system, a surveillance system can present an image of a source of possible disturbance to an operator more rapidly and precisely than through manual techniques.
