Abstract
An asset tracking device includes a mounting bracket and a housing attached to the mounting bracket. The mounting bracket includes a magnetic portion, first apertures that receive first fasteners for attaching the mounting bracket to the asset, and second apertures that receive second fasteners. Third apertures in the housing, aligned with the second apertures in the mounting bracket, receive the second fasteners for attaching the housing to the mounting bracket. When the housing is attached to the mounting bracket, the housing makes the fasteners in the mounting bracket inaccessible so that the mounting bracket cannot be removed from the asset. When the housing is removed from the mounting bracket, a magnetic switch changes state and triggers a controller to generate a tamper alert with location information indicating the location of the tracking device. A wireless transmitter wirelessly transmits the tamper alert and location information to a central monitoring station.
