Security barriers, systems and methods
View Patent ↗Systems, arrangements, barriers and methods for detecting illicit attempts to compromise or penetrate a physical barrier are disclosed. The systems, arrangements, barriers and methods detect illicit attempts to pry, remove or compromise a security barrier from the surface or location it protects, by insider/outsider adversaries, when any type of cabled continuity sensor (optical, electrical) is woven, embedded, or interlaced through the security barrier.
1. A security harrier system, comprising:
a hasp attached to a base member, the hasp comprising a through passage;
an outer layer joined to the base member; and
a sensor passing or woven through the outer layer and the through passage of the hasp, the sensor sensing a sensed condition;
wherein the hasp is configured to deform or sever the sensor to degrade, improve or otherwise cause a change in the sensed condition when the outer member moves relative to the base member; and
wherein the sensor is selected from a group consisting essentially of a wire, cable, fiber and conduit.
2. The barrier system of claim 1 , further comprising:
one or more intermediate layers disposed between the outer layer and the base member.
3. The barrier system of claim 1 , wherein the sensed condition is selected from a group consisting of an electro-magnetic condition, an opto-electric condition, a seismic condition, an acoustic condition, and fluid pressure condition.
4. The barrier of claim 3 , wherein the electro-magnetic condition is selected from a group consisting of electrical conductivity, electrical resistance and electrical continuity.
5. The barrier system of claim 1 , wherein the sensor is a fiber optic cable.
6. The barrier system of claim 1 , wherein the sensor is an electrically conductive wire or cable.
7. The barrier system of claim 1 , further comprising:
a cap layer disposed over the outer layer.
8. A security arrangement, comprising:
a security enclosure surrounding an inside space, the security enclosure comprising:
a barrier comprising:
a base member; and
an outer layer disposed upon the base member, the outer layer comprising a passageway;
wherein the security enclosure is configured to prohibit access to the inside space; and
a security system comprising:
a hasp attached to the base member, the hasp comprising an aperture; and
a sensor passing or woven through the passageway of the outer layer and aperture of the hasp, the sensor sensing a sensed condition;
wherein the hasp is configured to deform or severe the sensor to degrade, improve or otherwise cause a change in the sensed condition when the outer member moves relative to the base member; and
wherein the sensor is selected from a group consisting essentially of wire, cable, fiber and conduit.
9. The security arrangement of claim 8 , wherein the barrier further comprises one or more intermediate layers disposed between the outer layer and the base member.
10. The security arrangement of claim 8 , wherein the sensed condition is selected from a group consisting of an electro-magnetic condition, an opto-electric condition, a seismic condition, an acoustic condition, and fluid pressure condition.
11. The security arrangement of claim 10 , wherein the electro-magnetic condition is selected from a group consisting of electrical conductivity, electrical resistance and electrical continuity.
12. The security arrangement of claim 8 , wherein the sensor is a fiber optic cable.
13. The security arrangement of claim 8 , wherein the sensor is an electrically conductive wire or cable.
14. The security arrangement of claim 8 , wherein the barrier further comprises a cap layer disposed over the outer layer.
15. A method for monitoring an enclosure, comprising:
fastening a hasp having an aperture to a base member of a structure;
covering the hasp with an outer layer; and
passing a sensor through the outer layer and the aperture of the hasp; wherein prying, separating or partially separating the outer layer from the base member causes the hasp to deform or severe the sensor, thereby causing a change in a sensed condition of the sensor;
wherein the sensor is selected from a group consisting essentially of a wire, cable, fiber and conduit.
16. The method of claim 15 , wherein the sensed condition is selected from a group consisting of an electro-magnetic condition, an opto-electric condition, a seismic q condition, an acoustic condition, and fluid pressure condition.
17. The method of claim 15 , further comprising:
alerting a user to the change in the sensed condition of the sensor.
18. The method of claim 16 , wherein the electro-magnetic condition is selected from a group consisting of electrical conductivity, electrical resistance and electrical continuity.
19. The method of claim 15 , wherein the sensor is a cable, and the cable is a fiber optic cable.
20. The method of claim 15 , wherein the sensor is a wire or cable, and the wire or cable is a conductive wire or cable.
