Abstract

A lockbox can comprise one or more sensors for detecting tampering with one or more portions of the lockbox. For example, in some embodiments the one or more sensors are configured to detect cutting or breaking of the shackle (or other portion of the lockbox) configured to secure the lockbox to another object. As a result of detecting tampering, a wireless communication device coupled to the lockbox transmits a notification to a monitoring station. Some embodiments of the lockbox perform detection and transmission of lockbox position data.

Claims

1. A lockbox comprising:

a securable storage area for securing a key;

a fastening element configured to removably fasten the lockbox to another object;

a detection unit configured to detect tampering with the lockbox; and

a wireless communication device coupled to the detection unit and configured to transmit a signal to a monitoring station when the detection unit detects tampering with the lockbox.

2. The lockbox of claim 1, further comprising a satellite navigation system receiver coupled to the lockbox, wherein the wireless communication device is configured to transmit lockbox location data to the monitoring station.

3. The lockbox of claim 2, wherein the wireless communication device is configured to transmit the lockbox location data to the monitoring station as a result of detecting tampering with the lockbox.

4. The lockbox of claim 1, wherein the detection unit is configured to detect tampering with the fastening element.

5. The lockbox of claim 1, wherein the fastening element comprises a shackle.

6. The lockbox of claim 1, wherein the detection unit is configured to detect tampering with the storage area.

7. The lockbox of claim 1, wherein the detection unit comprises an electrical sensor.

8. The lockbox of claim 1, wherein the detection unit comprises a magnetic sensor.

9. The lockbox of claim 1, wherein the detection unit comprises an accelerometer.

10. The lockbox of claim 9, wherein the detection unit is configured to transmit the signal to the monitoring station if motion detected by the accelerometer exceeds a selected time or intensity threshold.

11. The lockbox of claim 1, further comprising means for determining at least the approximate geographic location of the lockbox.

12. A method of monitoring a lockbox comprising:

detecting by the lockbox, in approximately real-time, one or more indications of tampering with the lockbox; and

as a result of the detecting, wirelessly transmitting an alert signal from the lockbox to a monitoring station.

13. The method of claim 12, further comprising wirelessly transmitting location information to the monitoring station.

14. The method of claim 13, wherein the location information is transmitted to the monitoring station at a predetermined interval.

15. The method of claim 12, further comprising providing an indicator of the alert signal to a law enforcement agency.

16. A system for monitoring a lockbox at a property, the system comprising:

a lockbox comprising an area for storing a key to the property, wherein the lockbox is configured to detect tampering with the lockbox and to wirelessly transmit an indicator of the tampering approximately in real-time with the tampering; and

a monitoring station configured to receive the indicator and provide a description of the indicator to a user.

17. The system of claim 16, wherein the lockbox is further configured to wirelessly transmit lockbox location information to the monitoring station.
