Intrusion detection system and sensor device thereof

A sensor device that transmits a modulation wave of a transmission spectrum diffusion signal to a transmission leakage transfer passage, receives the modulation wave having leaked from the transmission leakage transfer passage to a reception leakage transfer passage, and detects an intrusion of an object to be detected into an area subject to monitoring for an intrusion of an object to be detected on the basis of the received modulation wave, the sensor device comprising:

• a reference clock generator that generates a reference clock signal;
• an output amplifier that is connected to an output terminal of the reference clock generator so as to output the reference clock signal generated by the reference clock generator to an external device;
• an input amplifier that inputs a reference clock signal from an external device;
• and
• a switchover switch that selectively supplies either one of the reference clock signal generated by the reference clock generator and a reference clock signal from the external device input by the input amplifier to a transmission spectrum diffusion signal generator,
• wherein the transmission spectrum diffusion signal generator generates the transmission spectrum diffusion signal on the basis of a reference clock signal selectively supplied via the switchover switch.
