Embodiments of the present invention are directed to security systems for securing an item of merchandise from theft or unauthorized removal. For example, the security system may include a sensor configured to be coupled to the item of merchandise and a base configured to removably support the sensor and the item of merchandise thereon. The sensor includes at least one electrical contact and an inductive coil, and the base includes at least one electrical contact and driving electronics for the inductive coil. The sensor is configured to transfer power inductively to the item of merchandise when the at least one electrical contact of the sensor contacts the at least one electrical contact of the base to thereby allow the driving electronics to energize the inductive coil, wherein the sensor is configured to cease transferring power to the item of merchandise when the sensor is lifted off of the base.
