ABSTRACT:
A trespass detection system includes an electronic-wave trespass detection sensor which is provided near the boundary of a trespass surveillance area, and a detection device body which detects trespassing into the area on the basis of a detection output from the sensor. The detection device body includes a change quantity storing unit which stores the quantity of change in electric field intensity over a predetermined period for each detection zone that is set in advance along the direction of extension of the electronic-wave trespass detection sensor, a statistical processing unit which statistically processes each of the quantities of change, a threshold value setting unit which corrects a threshold value on the basis of the result of the processing and sets a new threshold value, and a trespass detection determining unit which compares the quantity of change and the threshold value and thus determines that there is trespassing by an object.
