Fiber Optic Cable Perimeter Detection
Fibre optic detection can be used on fences, walls and other perimeter structures. On fences, the sensing cable detects activity such as climbing, cutting, lifting, impact and tampering. Whether a perimeter is 10 meters long or more than 500 kilometres, both require a solution that delivers a high probability of detection with minimal nuisance alarms. The technology protects outdoor perimeters and physical data networks where early detection and precise location matter. The solution of choice for the most security conscious industrial, military and government organisations, FFT's. By utilizing existing or dedicated optical fibers as thousands of virtual microphones, DAS enables real-time detection, classification, and localization of activity along borders and perimeters. -
