A security system for use in connection with cargo containers and other enclosed spaces. The system monitors vibrations associated with a container and detects signals representative events indicating that an unauthorized access has been made to the container. The system may be programmed with a library of event signatures, allowing different types of events to be detected. The system may be provided with a library of signatures representing a heart beating with a beat pattern and the system may be used to detect a human or other animal within the container. Alternatively, the system may be provided with a library of signatures representing piercing the container. The system may be used to monitor containers in transit. Indications of events may be stored while the container is in transit and then communicated at a security check point.
