ABSTRACT:
A system and method for constructing a security system for a building using at least one RFID reader to communicate with at least one RFID transponder to provide the radio link between each of a number of openings and a controller capable of causing an alert in the event of an intrusion. The RFID transponder is connected to an intrusion sensor. The controller preferably communicates with the RFID reader using a power line communications protocol. The RFID transponder can contain a battery. The RFID reader contains means for transferring power to an RFID transponder for the purpose of charging any battery. The security system can contain more than one controller, whereby the RFID reader can communicate with more than one controller.
