Shipping container security system and method
First Claim
1. A security system for shipping containers comprising:
- a system monitor; and
,a device mounted on said shipping container comprising;
a measurement circuit to measure at least one condition of said container selected from the group consisting of;
time, light level, location, speed, and acceleration;
a tamper sensing system including at least one parameter that is adjusted based on the changes in said measured condition; and
,a communication system whereby said tamper sensing system alerts said system monitor when tampering is detected.

Abstract
A security system for shipping containers includes: a system monitor and a device mounted on the container for locking and/or tracking. The device includes a means of measuring at least one condition of said container (e.g., time of day, ambient light level, location, speed, and acceleration), a tamper sensing system that can be adjusted based on the changes in the measured condition, and a communication system for the tamper sensing system to alert the system monitor when tampering is detected. The tamper sensing system may employ a number of approaches for detecting a tampering event, including vibration, heat, load, impact, and acceleration sensing, as well as changes in location. The tamper sensing system may further disable the lock if tampering is detected.
