Abstract

A system is provided including a plurality of inter-connected premises management devices, each including one or more sensors that generate data about an environment, and a control device to control one or more operations of the premises management system, the control device including a movement detector. The premises management system detects an attempt by an intruder to damage the control device based on data from the movement detector indicating an abnormal movement applied to the control device, historical data obtained from the sensors, and current data obtained from the sensors.

Claims

1-20. -20. (canceled)

22. A premises management system, comprising:

a control device configured to control one or more operations of the premises management system, the control device including a movement detector configured to generate a signal indicative of an intensity of any detected movement of the control device, a receiver to receive data from one or more external sensors, and a processor configured to determine whether a physical attack on the control device has occurred based on;

(1) a signal generated by the movement detector that indicates detected movement above a threshold intensity amount, and (2) the data from the one or more external sensors.

23. The premises management system of claim 22, wherein the processor determines that the physical attack on the control device has occurred by generating a score based on weighting a plurality of factors, the plurality of factors including at least the data from the one or more external sensors.

24. The premises management system of claim 23, wherein the processor is further configured to transmit a signal to the premises management system to select a different device to function as the control device when the score is above a first threshold.

25. The premises management system of claim 23, wherein the plurality of factors includes the signal that indicated detected movement.

26. The premises management system of claim 23, wherein the plurality of factors includes historical data generated by the one or more external sensors.

27. The premises management system of claim 23, wherein at least one factor among the plurality of factors is weighted based on a distance of a source of the factor from the control device.

28. The premises management system of claim 27, wherein a first source that is disposed closer to the control device than a second source is given greater weight than the second source.

29. The premises management system of claim 23, wherein at least one factor among the plurality of factors is weighted based on a reliability estimation of a source of the at least one factor.

30. The premises management system of claim 29, wherein the reliability estimation is based on historical data indicating that the source has provided data that led to one or more false alarms.

31. The premises management system of claim 22, wherein at least one of the one or more external sensors is a network connected wall switch.

32. The premises management system of claim 22, wherein at least one of the one or more external sensors is a network connected thermostat.

33. The premises management system of claim 22, wherein at least one of the one or more external sensors is a network connected hazard detector.

34. The premises management system of claim 22, wherein the one or more external sensors are located in a different room of the premises than the control device.

35. A method of detecting and handling a physical attack on a control device of a premises management system, comprising:

generating, by a control device, a signal indicative of an intensity of detected movement of the control device;

receiving, by the control device, data from external sensors, the data indicating a state or condition of a premises; and

when the signal indicates detected movement above a threshold intensity level, generating a score based on weighting a plurality of factors, the plurality of factors including at least the data from the one or more external sensors, and

determining that a physical attack on the control device has occurred based on the score.

36. The method of claim 35, further comprising selecting a device other than the control device to execute the functions of the control device when the score is above a first threshold.

37. The method of claim 35, wherein the plurality of factors includes the signal that indicated detected movement.

38. The method of claim 35, wherein the plurality of factors includes historical data generated by the one or more external sensors.

39. The method of claim 35, wherein at least one factor among the plurality of factors is weighted based on a distance of a source of the factor from the control device.

40. The method of claim 39, wherein a first source that is disposed closer to the control device than a second source is given greater weight than the second source.

41. The method of claim 35, wherein at least one factor among the plurality of factors is weighted based on a reliability estimation of a source of the at least one factor.

42. The method of claim 35, wherein the reliability estimation is based on historical data indicating that the source has provided data that led to one or more false alarms.
