。 A microwave is emitted, the microwave hits a person or object entering a given space, and the reflected wave is captured, and the Doppler effect of the reflected wave prevents the person or object from entering the space. This is an intrusion detection device that detects a microwave oscillator and a flat antenna that emits microwaves oscillated by the oscillator, and is difficult to identify when visually inspected from the surface. The device is configured to be able to catch the reflected wave when the microwave emitted by the antenna hits the second hand of the clock, and the device operates by the Doppler effect of the reflected wave from the second hand of the clock. An intrusion detection device configured to be able to self-diagnose whether or not there is an intrusion detection device.
