摘要： Systems, devices, and methods are disclosed for securing a theft-susceptible movable object at a selected location. A security system is positioned at a selected location for protection of a theft-susceptible movable object. The security system includes a magnetic field source adapted to generate a magnetic field that is positionally-associated with a movable object. A monitoring device includes a magnetic sensor and is adapted for placement proximate to the selected location. The monitoring device is adapted to take one or more measurements of the magnetic field and to detect alteration in the measurements caused by movement of the magnetic field source relative to the monitoring device when the movable object is moved from the selected location. Upon detecting the alteration in the measurements of the magnetic field, the monitoring device is adapted to output an electronic warning signal indicating that the movable object has moved from the selected location.
