INTRUSION DETECTION DEVICE, INTRUSION DETECTION METHOD, INTRUSION DETECTION PROGRAM, AND INTRUSION DETECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress erroneous detection in a configuration for detecting an intrusion of a person using an electric wave in a predetermined area, even when there are many other electric waves having frequency bands equal or close to that of the electric wave to be used.

SOLUTION: An intrusion detection device 101 comprises: a receiving part 22 that selectively receives a target wireless signal from wireless signals transmitted from a plurality of devices in a predetermined area; a spatial feature amount calculating part 11 that calculates a spatial feature amount in the predetermined area on the basis of the target wireless signal received by the receiving part 22; a detecting part 12 that detects a motion of a person in the predetermined area on the basis of the spatial feature amount calculated by the spatial feature amount calculation part 11; and a timing control part 14 that controls a timing at which the target wireless signal is transmitted. The receiving part 22 selectively receives the target wireless signal from the wireless signals according to the timing controlled by the timing control part 14.
