Tethered security system with wireless communication
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 base includes a charging circuit for providing power to the sensor and/or the item of merchandise. The security system also includes a controller operably coupled to the base and a key configured to wirelessly communicate with the base and/or controller. The sensor is configured to wirelessly communicate with the base.
1. A security system for securing an item of merchandise from theft or unauthorized removal, the security system comprising:
a sensor configured to be coupled to an item of merchandise and configured to detect removal of the item of merchandise from the sensor;
a base configured to removably support the sensor and the item of merchandise;
a cable;
a connector at the end of the cable configured to removably connect to the sensor;
a recoiler connected to the cable, the cable configured to be extended from the base when the sensor and the item of merchandise are lifted off of the base, and the recoiler configured to retract the cable within the base when the sensor and the item of merchandise are returned to the base; and
a lock mechanism disposed within the base and configured to engage the connector for locking the sensor on the base to prevent the cable from being extended from the base.
2. The security system of claim 1 , wherein the lock mechanism comprises a fastener.
3. The security system of claim 1 , further comprising a charging circuit housed within the base for providing power to the sensor and/or the item of merchandise when the sensor is supported on the base.
4. 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.
5. The security system of claim 1 , wherein the sensor comprises at least one electrical contact and the base comprises at least one electrical contact, wherein the base is configured to transfer power to the sensor and/or the item of merchandise via the electrical contacts when the sensor is supported on the base, and wherein the base is configured to cease transferring power to the sensor and/or the item of merchandise when the sensor is lifted off of the base.
6. The security system of claim 5 , wherein the cable comprises a plurality of electrical conductors extending along its length for defining a sense loop.
7. The security system of claim 1 , wherein the cable does not transmit power to the sensor and/or the item of merchandise.
8. The security system of claim 1 , wherein the lock mechanism is actuatable with a key.
9. The security system of claim 1 , wherein the sensor is configured to wirelessly communicate with the base for detecting a security event.
10. The security system of claim 1 , wherein the lock mechanism comprises electro-mechanical means for locking the sensor on the base.
11. The security system of claim 1 , wherein the sensor is configured to rotate relative to the cable via the connector.
12. The security system of claim 1 , wherein the recoiler is housed within the base.
13. 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.
14. The security system of claim 1 , wherein the cable is inaccessible when the sensor is locked to the base with the lock mechanism.
15. The security system of claim 1 , further comprising an alarm configured to generate an alarm signal when the item of merchandise is removed from the sensor or the cable is cut, shorted, or disconnected.
16. The security system of claim 15 , further comprising a key configured to wirelessly communicate with the base for arming or disarming the alarm.
17. The security system of claim 1 , wherein the cable does not transmit power to the sensor and/or the item of merchandise.
18. The security system of claim 1 , wherein the base defines an opening configured to receive the connector therein, and wherein the lock mechanism is configured to extend within the opening to engage the connector.
19. A security system for securing an item of merchandise from theft or unauthorized removal, the security system comprising:
a sensor configured to be coupled to an item of merchandise and configured to detect removal of the item of merchandise from the sensor;
a base configured to removably support the sensor and the item of merchandise;
a cable operably connected to the base;
a connector at the end of the cable configured to removably connect to the sensor; and
a lock mechanism disposed within the base and configured to engage the connector for locking the sensor on the base to prevent the cable from being extended relative to the base.
20. A method for securing an item of merchandise from theft or unauthorized removal, the method comprising:
coupling a sensor to an item of merchandise configured to detect removal of the item of merchandise from the sensor;
attaching a connector at the end of the cable to the sensor, the cable operably connected to a base at an opposite end;
removably supporting the sensor and the item of merchandise on the base; and
locking the sensor on the base with a lock mechanism disposed within the base via engagement of the connector to prevent the cable from being extended relative to the base.
