Abstract

A security, monitoring and/or detection system is described. In several exemplary embodiments, the system secures, monitors, and/or detects movement across, a boundary extending across, for example, a relatively large geographic area such as, for example, a transnational border.

Claims

1. A system comprising:

one or more fiber optic cables buried underground and at least proximate a boundary between at least two areas, the one or more fiber optic cables having one or more operating parameters; and

a driver for detecting the one or more operating parameters.

2. The system of claim 1 wherein the at least two areas comprise first and second nation states, and the boundary comprises a transnational boundary between the first and second nation states.

3. The system of claim 1 wherein the first and second fiber optic cables extend in a direction generally corresponding to the direction of extension of the boundary between the at least two areas.

4. A system comprising:

first and second fiber optic cables located below a ground level and at least proximate a boundary between at least two areas; and

a driver operably coupled to the first and second fiber optic cables and located below the ground level.

5. The system of claim 4 wherein the at least two areas are first and second nation states, respectively, and the boundary is a transnational boundary between the first and second nation states.

6. The system of claim 4 wherein the first and second fiber optic cables extend in a direction generally corresponding to the direction of extension of the boundary between the at least two areas.

7. A method comprising:

burying first and second fiber optic cables in the vicinity of a boundary between at least two areas; and

detecting motion in the vicinity of the boundary between the at least two areas, comprising;

determining a first operating parameter of the first fiber optic cable; and

comparing the first operating parameter with a second operating parameter of the second fiber optic cable.

8. The method of claim 7 wherein the at least two areas are first and second nation states, respectively, and the boundary is a transnational boundary between the first and second nation states.

9. The method of claim 7 wherein the first and second fiber optic cables extend in a direction generally corresponding to the direction of extension of the boundary between the at least two areas.

10. A method comprising:

burying one or more fiber optic cables in the vicinity of a boundary between at least two areas; and

detecting motion in the vicinity of the boundary between the at least two areas using the one or more fiber optic cables.

11. The method of claim 13 wherein the at least two areas are first and second nation states, respectively, and the boundary is a transnational boundary between the first and second nation states.

12. The method of claim 13 wherein the first and second fiber optic cables extend in a direction generally corresponding to the direction of extension of the boundary between the at least two areas.
