SYSTEM AND METHOD FOR SECURING A LARGE INFRASTRUCTURE.

摘要

A security monitoring system (10) for a large infrastructure (12) is provided. The system includes several magnetometers (14) disposed around an area (16) of the infrastructure. According to aspects of present technique at least one magnetometer (28) is configured to relay an alert signal indicating a change in a magnetic flux profile around the area. A central unit (56) is configured to receive the alert signal from at least one magnetometer and initiate a response to the alert signal.
