SABRE FIDS: Advanced Fiber Optic
SABRE FIDS : Advanced Fiber Optic based Perimeter Intrusion Detection
Secure Your Critical Infrastructure with Fiber Optic Precision
The SABRE FIDS (Fiber Optic Intrusion Detection System) series by Sabrefonic is a world-class range of perimeter security solutions designed to protect high-value and sensitive sites. Unlike traditional electronic security, SABRE FIDS utilizes sophisticated fiber optic sensing technology to detect, locate, and alert security teams to intrusion attempts in real-time.

How It Works
SABRE FIDS operates by transmitting laser light along a fiber optic cable. The system analyses the return pattern of the light to detect minute disturbances.
Intrusion Detection
It identifies vibrations, flexing, or compression caused by climbing, cutting, or digging.
Smart Analytics
Advanced Signal Processing Units (SPUs) use environmental compensation algorithms to distinguish between a real human intrusion and nuisance alarms caused by wind, rain, or small animals.
Total Immunity
Because the sensors use light rather than electricity, they are 100% immune to Electromagnetic Interference (EMI), radio frequency interference, and lightning strikes—making them ideal for airports and power plants.
