RFID based security system
First Claim
1. A security system for use in a building with at least a first opening to be monitored for intrusion, said security system comprising:
- at least a first controller and a second controller, at least a first intrusion sensor monitoring at least the first opening, said first intrusion sensor being connected to a first RFID transponder, at least a first RFID reader in wireless communications with at least said first RFID transponder, and in communications with at least the first controller, wherein said first controller and said second controller both receive communications from said RFID reader indicating whether said intrusion sensor has detected an intrusion, and wherein said first controller and said second controller contain arbitration logic to determine which of said first controller and said second controller will in turn cause an alert indicating that said intrusion sensor has detected an intrusion.

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.

1. A security system for use in a building with at least a first opening to be monitored for intrusion, said security system comprising:
-
at least a first controller and a second controller, at least a first intrusion sensor monitoring at least the first opening, said first intrusion sensor being connected to a first RFID transponder, at least a first RFID reader in wireless communications with at least said first RFID transponder, and in communications with at least the first controller, wherein said first controller and said second controller both receive communications from said RFID reader indicating whether said intrusion sensor has detected an intrusion, and wherein said first controller and said second controller contain arbitration logic to determine which of said first controller and said second controller will in turn cause an alert indicating that said intrusion sensor has detected an intrusion. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. An RFID reader for use in a security system that monitors a building for possible intrusion, said RFID reader comprising:
-
means for communicating with at least a first controller and a second controller in a security system capable of causing an alert, wherein said first controller and said second controller contain arbitration logic to determine which of said first controller and said second controller will cause an alert indicating that an intrusion sensor has detected an intrusion, means for communicating with at least a first RFID transponder using wireless communication, logic, implemented in either firmware of software, for receiving a message from at least said first RFID transponder indicating whether the intrusion sensor has detected an intrusion, and logic, implemented in either firmware or software, for sending a message to at least said first controller and said second controller of the security system indicating whether the intrusion sensor has detected an intrusion. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method of monitoring intrusion in a building comprising at least a first opening, said method comprising the steps of:
-
detecting an intrusion with at least a first intrusion sensor, receiving a message from at least a first RFID transponder at a first RFID reader indicating that said intrusion sensor has detected the intrusion, receiving a message at at least a first and a second controller from at least said first RFID reader indicating that said first intrusion sensor has detected the intrusion, determining, using arbitration logic, which of said first controller and said second controller will cause an alert indicating that said first intrusion sensor has detected the intrusion, and causing the alert. - View Dependent Claims (30, 31, 32)
