Wireless monitoring device
First Claim
1. A security system for monitoring a cargo storage compartment, the system comprising:
- a cargo storage compartment;
a sensor positioned within the storage compartment and capable of emitting and receiving a monitoring signal;
monitoring electronics positioned within the storage compartment and connected to the sensor, said monitoring electronics capable of comparing the emitted and received signals of the sensor and identifying a triggering event based on the comparison of the emitted and received signals; and
an active RFID tag positioned within the storage compartment and connected to the monitoring electronics and capable of storing data about a triggering event and;
wherein said active RFID is further configured to receive radio transmissions for initiating operation of said sensor.

Abstract
The system of the invention includes a method for monitoring changes in the status or condition of a Container using one or more monitoring units mounted to the Container. The monitoring units preferably include a power supply, sensors using reflective energy with programmable parameters, globally-unique sensor identification, recording capability on a timeline, long term memory and the ability to rebroadcast information on RFID radio technology. Programmable monitoring hardware in the monitoring unit detects significant changes in the sensor outputs as a triggering event. The programmable monitoring hardware includes memory for storing identification information for the Container. The sensors which can include conventional devices that detect various forms of energy including visible light, infrared light, magnetic fields, radio frequency energy and sound. In one embodiment, a monitoring unit is mounted inside a shipping Container suitable for long distance transport. The triggering event can be used for tamper detection security.
