In this state, it is determined that the sensor unit 1 has detected the intruding object Q in the first inner specific area AC1. Conversely, even if the detection signal PD is output from the sensor unit 1, when the detection signal MD2 is output, the output of the knot circuit 57 becomes low level, so that the object detection signal DE1 Is not output.

Therefore, even if a car or a person is detected by the camera 2 in the outer second specific area AC2 and the output signal of the knot circuit 57 is at a low level, the intruding object Q exists in the inner first specific area AC1. If this is done, The object detection signal DE1 is output when both of them detect. Therefore, a stable sensor-camera-linked intrusion detection device that can reliably detect the intruding object Q in the first specific area AC1.
