15. The security system of claim 1, wherein the charging circuit is configured to provide power to the item of merchandise.

16. The security system of claim 1, wherein the cable comprises at least one electrical conductor extending along its length for defining a sense loop, and wherein the charging circuit and the at least one electrical conductor are electrically isolated from one another.

17. The security system of claim 16, wherein the cable comprises a pair of electrical conductors.

18. The security system of claim 1, wherein the sensor is configured to wirelessly communicate with the base for detecting a security event.

19. The security system of claim 1, further comprising a connector configured to connect the sensor to the cable, and wherein the lock mechanism is configured to engage the connector.

20. The security system of claim 1, wherein the lock mechanism comprises electro-mechanical means for locking the sensor on the base.

21. The security system of claim 1, wherein the base is configured to be mounted on top of a support surface, and wherein the base comprises a switch configured to detect removal of the base from the support surface.

22. A security system for securing an item of merchandise from theft or unauthorized removal, the security system comprising:
