More Information
Summary:A system, method, and apparatus for monitoring and detecting movement of components of a shipping container latch. A latch monitor may embody an electromagnetic sensing unit and a nearby magnet or light emitter for measuring and characterizing the profile of a nearby electromagnetic field. The field profile is monitored to detect a change in the profile, log the change, and report any abnormal disturbance to the electromagnetic field, indicating a breach of the integrity of a latching mechanism on a shipping container. An alert of a breach event may be sent via a communication network to an authority for response. The invention can distinguish authorized, incidental, and tampering events, and also store and upload an electronic manifest for a shipping container.
