<p>PROBLEM TO BE SOLVED: To make it easy to adjust a detection area in a monitor space and accurately and speedily judge that a human body enter or exits from the area by arranging the human body detecting device right above in the monitor space and forming the movement detection area only right below the human detecting device. SOLUTION: The infrared human body detector 10 is installed right above the entrance exit D of the monitor space and the movement detection area A is formed only right below the human body detecting device 10. Thus, the movement detection area A is formed and then a human body M which enters or exits from the monitor space certainly passes through the movement detection area, so it can accurately be judged that the human body M enters or exits from the area. In this case, the human body detecting device is only installed irrelevantly to the extent of the monitor space so that the movement detection area is formed only right below the entrance exit D, and only the fitting height is considered for accurate human body detection. Therefore, the area of detection areas A and B corresponding to the height is only determined.</p> |
