Abstract: An intrusion detection system and method utilizing a power transmission cable connected to a source of radio frequency signals. A data transmission cable is associated with the power transmission cable and is provided with a plurality of radio frequency identification chips. The power transmission cable would induce an electromagnetic field within the data transmission cable allowing each of the RFID chips to transmit a signal during normal operation. However, if an intrusion occurs or the power transmission cable or data transmission cable is severed, the system according to the present invention, would be able to determine the exact point of intrusion based upon the signals received or not received from the RFID chips.
