PURPOSE: A security system using a different kind camera and a method thereof are provided to photograph a clear image using a narrow viewing angle camera moving by movement of a subject, thereby reducing system installation costs. CONSTITUTION: A wide viewing angle camera(11) photographs a broad monitoring region. A narrow viewing angle camera(12) has higher resolution than the wide viewing angle camera and photographs a narrower region. A driving device unit(13) partially photographs the monitoring area by adjusting an angle of the narrow viewing angle camera. A control device unit(20) detects a pixel region where a subject moves from image data photographed by the wide viewing angle camera. The control device unit controls an angle of the narrow viewing angle camera to photograph the pixel region.
