Abstract

An asset subsystem is provided for use in a security system. The security system includes a security system controller operable to trigger an alarm. The asset subsystem includes a transceiver operable to communicate a first signal to a tag associated with an asset and to receive a second signal communicated by the tag in response to the first signal. The asset subsystem also includes a controller operable to determine whether the tag failed to communicate the second signal to the transceiver and trigger the alarm in response to determining that the tag failed to communicate the second signal to the transceiver.

Claims

1. An asset monitoring system, comprising:

a transceiver operable to communicate with a tag associated with an asset; and

a controller operable to determine whether the tag fails to communicate with the controller and to trigger an alarm of a security system in response to the determination, the security system comprising a security system controller operable to use input from a plurality of sensors to determine whether to trigger the alarm, the sensors configured to monitor a plurality of characteristics associated with a monitored structure, the controller appearing as another one of the sensors to the security system controller.

2. The asset monitoring system of claim 1, wherein the plurality of sensors includes at least one of:

a sensor operable to detect when a door is opened, a sensor operable to detect when a window is opened, and a sensor operable to detect movement in a specified area; and

wherein the controller appears to the security system controller as one of;

a door sensor, a window sensor, and a motion sensor.

3. The asset monitoring system of claim 1, wherein:

the tag is operable to receive input from a motion sensor, the motion sensor operable to detect movement of the asset, the tag also operable to inform the controller of detected movement of the asset; and

the controller is further operable to trigger the alarm when the tag reports the detected movement and the asset is not allowed to be moved.

4. The asset monitoring system of claim 1, wherein the transceiver and the controller form at least part of a portable unit.

5. The asset monitoring system of claim 4, wherein the portable unit is adapted to be placed in a cradle, the cradle operable to provide an interface between the portable unit and the security system controller.

6. The asset monitoring system of claim 5, wherein the cradle comprises a display, the display operable to identify the asset associated with the tag when the alarm is triggered in response to the tag failing to communicate with the controller.

7. The asset monitoring system of claim 1, further comprising an interface operable to facilitate communication between the controller and the security system controller, the interface configured to make the controller appear as another one of the sensors to the security system controller.

8. The asset monitoring system of claim 7, wherein the interface is integrated into the controller.

9. The asset monitoring system of claim 1, wherein the security system is operable to monitor at least one of:

a residence, a business, a storage area, and a government building.

10. A security system, comprising:

an alarm;

a plurality of sensors configured to monitor a plurality of characteristics associated with a monitored structure;

a security system controller operable to trigger the alarm based on input from the sensors;

a transceiver operable to communicate with a tag associated with an asset; and

a controller operable to determine whether the tag fails to communicate with the controller and to trigger the alarm in response to the determination, the controller appearing as another one of the sensors to the security system controller.

11. The security system of claim 10, wherein the plurality of sensors includes at least one of:

a sensor operable to detect when a door is opened, a sensor operable to detect when a window is opened, and a sensor operable to detect movement in a specified area; and

wherein the controller appears to the security system controller as one of;

a door sensor, a window sensor, and a motion sensor.

12. The security system of claim 10, wherein:

the tag is operable to receive input from a motion sensor, the motion sensor operable to detect movement of the asset, the tag also operable to inform the controller of detected movement of the asset; and

the controller is further operable to trigger the alarm when the tag reports the detected movement and the asset is not allowed to be moved.

13. The security system of claim 10, wherein the transceiver and the controller form at least part of a portable unit.

14. The security system of claim 13, wherein the portable unit is adapted to be placed in a cradle, the cradle operable to provide an interface between the portable unit and the security system controller.

15. The security system of claim 14, wherein the cradle comprises a display, the display operable to identify the asset associated with the tag when the alarm is triggered in response to the tag failing to communicate with the controller.

16. The security system of claim 10, further comprising an interface operable to facilitate communication between the controller and the security system controller, the interface configured to make the controller appear as another one of the sensors to the security system controller.

17. The security system of claim 16, wherein the interface is integrated into the controller.

18. A method, comprising:

determining whether to trigger an alarm based on the input from the sensors;

determining whether a tag associated with an asset fails to communicate a signal, the asset located in or near the structure; and

triggering the alarm in response to determining that the tag fails to communicate the signal;

wherein an asset controller determines whether the tag fails to communicate the signal, the asset controller appearing as another one of the sensors to a security system controller in the security system, the security system controller triggering the alarm.

19. The method of claim 18, wherein:

the security system comprises a plurality of sensors including at least one of;

a sensor operable to detect when a door of the structure is opened, a sensor operable to detect when a window of the structure is opened, and a sensor operable to detect movement in or near the structure; and
