Fiber Optic Intrusion Detection & Physical Security Monitoring

The FiberStrike® LCM-940 pedestrian sensing platform uses UV light and fiber optic sensors to detect pedestrians in specific, secure locations, or restricted areas. The platform is a fiber-optic intrusion sensor system that can act as a “first alert” to trigger security cameras or alarms. The technology provides Point Detection Sensing to ascertain exact points of intrusion.

For example, fiber optic intrusion detection systems are used in railway, mass-transit, and sub-way platforms. The platform senses movements along defined paths, and intrusion detection along hallways or in front of doorways or hatches that access secure areas.

The use of fiber optic sensors as a physical security solution has multiple benefits. The key feature of FiberStrike® systems is the response time to an event which averages at 1.5 seconds. Since the sensors are passive, non-conductive, require no electrical power, and emit no signal, the connection will not be disrupted if power is cut.  They cannot be bypassed without detection, and they are superior to traditional electro-mechanical sensors due to their resistance to electromagnetic and radio frequency interference, lightning, and corrosion.

The intrusion detection platform may be directly buried, providing the capability to determine the location of pedestrian and vehicle traffic intrusion events over distances of many kilometers. Intrusion event location accuracy is approximately equal to fiber optic loop length 100 for a single fiber. Accuracy improves with the use of multiple co-located fiber loops, making false alarms virtually eliminated by CEL’s embedded, advanced designs and configurations.

Existing standard communications fiber infrastructures may be leveraged to connect a network of platforms, and multiple platforms may be leveraged to connect a network of platforms multiplexed over a single optical fiber while remaining individually addressable, simplifying the logistics and reducing the cost of installation.
