Process / Working
The SPEC-UWIDS system functions by transmitting infrared light pulses through a fiber-optic cable network. Any disruption caused by cutting, pressure changes, or tampering triggers an instant alarm, alerting security teams in real-time. The FiberMesh net is designed with dual-layer protection—its lower section detects breaches, while the upper section prevents climbing attempts. Integrated with surveillance and access control systems, SPEC-UWIDS ensures impenetrable underwater security for critical infrastructure.
