Abstract:

In certain embodiments, an intrusion detection device includes a magnetic field activated sensor and a cascading circuit. The magnetic field activated sensor is operable to detect movement of a corresponding component by sensing a magnetic flux variation of a magnetic device coupled to the component and generate a signal indicating that the corresponding component has moved. The cascading circuit is coupled to the magnetic field activated sensor and is operable to receive the signal generated by the magnetic field activated sensor and to generate a tamper detection signal if the signal indicating that the corresponding component has moved is received or if another tamper detection signal generated by another intrusion detection device is received.
