Abstract: A container breach detector system to monitor breaches of a transportation container. A self-contained container breach detector provides activation, status, and/or breach event date and time stamp data and a unique identification number of a communication tower, for a user to determine when and where authorized and/or unauthorized breaches of the transportation container occurred. Furthermore, the self-contained container breach detector serves as a recording device to record the activation, status, and/or breach event date and time stamp data; and communicates via various communication means including text via short message service, SMS, and/or e-mail. A container breach detector is intended for a one-time use only, to be discarded at destination. Each container breach detector has individual serial numbers.
