摘要： A cable lock device includes a housing, a tampering subsystem, and a cable having a first end and a second end. The first end is attached to the housing and is electrically connected to the tampering subsystem and the second end is selectively attached to the housing. In addition, a switch is disposed within the housing and is electrically connected to the tampering subsystem. The switch is movable between an open state and a closed state to indicate when the second end is attached to the housing. The tampering subsystem includes control circuitry that monitors the position of the switch and the status of the cable to detect removal of the second end from the housing and/or severance of the cable. The control circuitry relays status information of the cable lock device to a control unit via a transmitter to alert a property owner of a security breach.
