Abstract

An RFID based security system detects a lock/unlocked condition when securing a premise and an open/close condition of a window and/or door to monitor for an intruder. A local interface polls a RFID tag and relays a read value to a user panel for a determination if an intruder has opened a window and/or door. Alternately, the local interface is connected to at least one of a second local interface and the user panel to form a security network. The security network is relied on to convey security information to the user panel for a determination if an intruder has opened a window and/or door.

Claims

1. A security system, comprising:

a passive sensor to detect a change in condition of an access point to a building;

a wireless local interface to wirelessly poll said passive sensor for a binary value respectively associated with said change in condition.

2. The security system according to claim 1, further comprising:

a motion detector incorporated within said local interface to detect motion within a field of view of said local interface.

3. The security system according to claim 1, further comprising:

a capacitor connected to said passive sensor and to a passive sensor transceiver to activate an alert to signal a change in status during a period of time when said passive sensor is not polled by said wireless local interface.

4. The security system according to claim 1, further comprising:

a security network transceiver integrated with said wireless local interface to communicate with at least one of a second wireless local interface and a remote user panel.

5. The security system according to claim 4, wherein:

said security network transceiver is a Bluetooth™

transceiver.

6. The security system according to claim 1, wherein:

said wireless local interface plugs into a wall power outlet.

7. The security system according to claim 1, wherein:

said wireless local interface is integrated with a wall power outlet.

8. The security system according to claim 1, wherein:

said passive sensor is a RFID tag.

9. The security system according to claim 1, wherein:

said wireless local interface plugs into a wall power outlet.

10. The security system according to claim 1, further comprising:

a remote user panel to communicate with said wireless local interface.

11. The security system according to claim 10, wherein:

said remote user panel is connected to a speaker to sound an alert upon detection of a intruder from said passive sensor.

12. The security system according to claim 1, wherein:

said change in condition is an open/close condition.

13. The security system according to claim 1, wherein:

said change in condition is a lock/unlocked condition.

14. A method of surveying access points to a building, said method comprising:

passively detecting a change in condition of an access point to said building with a passive sensor; and

wirelessly polling said passive sensor for a binary value respectively associated with said change in condition with a wireless local interface.

15. The method of surveying access points to a building according to claim 14, further comprising:

detecting motion within a field of view of said local interface.

16. The method of surveying access points to a building according to claim 14, further comprising:

communicating with a second wireless local interface.

17. The method of surveying access points to a building according to claim 14, further comprising:

said change in condition is an open/close condition.

18. The method of surveying access points to a building according to claim 14, further comprising:

said change in condition is a lock/unlocked condition when alarming the premises.

19. A method of surveying access points to a building, comprising:

detecting at least one of motion within a field of view of a first local interface and a change in condition of an access point to said building; and

wirelessly communicating at least one of said detected motion and said change in condition over a security network to a second local interface.

20. The method of surveying access points to a building according to claim 19, wherein:

said security network is a Bluetooth™

network.

21. The method of surveying access points to a building according to claim 19, further comprising:

wirelessly polling a passive sensor for an open/close condition.

22. Apparatus for surveying access points to a building, comprising:

means for passively detecting a change in condition of an access point to a building with a passive sensor; and

means for wirelessly polling said passive sensor for a binary value respectively associated with said change in condition with a wireless local interface.

23. The apparatus for surveying access points to a building according to claim 22, further comprising:

said change in condition is an open/close condition.

24. The apparatus for surveying access points to a building according to claim 22, further comprising:

said change in condition is a lock/unlocked condition.

25. Apparatus for surveying access points to a building, comprising:

means for detecting at least one of motion within a field of view of a first local interface and a change in condition of an access point to a building; and

means for wirelessly communicating at least one of said detected motion and said change in condition over a security network to a second local interface.

26. The apparatus for surveying access points to a building according to claim 25, further comprising:

said change in condition is an open/close condition.

27. The apparatus for surveying access points to a building according to claim 25, further comprising:

said change in condition is a lock/unlocked condition.
