Anti-theft security device and perimeter detection system
DCFirst Claim
1. A security tag comprising:
- a housing securable to an object;
a tamper circuit disposed within the housing;
a monitoring device movably coupled to the housing for monitoring whether a party removes or attempts to remove the housing from the object, the monitoring device having a first end and a second end, wherein the first end is covered by the housing and the second end extending through an opening in the housing and adapted to releasably contact the object, wherein the monitoring device is movable relative to the housing between at least a first axial position and a second axial position, wherein in the first axial position the monitoring device causes the tamper circuit to be in a closed condition and wherein in the second axial position the monitoring device causes the tamper circuit to be in an open condition;
a transmitter;
a microprocessor disposed in the housing and in communication with the tamper circuit and the transmitter, wherein the microprocessor determines whether the security tag is in an unauthorized removal state or an authorized removal state and causes the transmitter to transmit a tamper signal when the security tag is in the unauthorized removal state and the tamper circuit is in the open condition.

9. A security system comprising:
-
a security tag operable for connection to an object; a monitoring device operable to monitor whether a party removes or attempts to remove the security tag from the object; an alarm operable to emit a tamper signal when the monitoring device indicates that a party has removed or attempted to remove the security tag from the object in an unauthorized condition, and wherein the alarm emits a warning alarm signal when the security tag is moved away from a predefined authorized location based on information generated by a location detection device within the security tag or information in a wireless signal received from a remote device, wherein the security tag broadcasts an identification signal separate from the tamper signal and the warning alarm signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
