Fiber Sensys

For proven high-performance and reliability, wherever perimeter protection is needed the Fiber Sensys family of fiber-optic intrusion detection systems are the ultimate in perimeter protection.  Impervious to fog, darkness, dust, and lightning, they serve as constant sentinels, but their price has been prohibitive for many applications – until now.


Designed specifically for price-sensitive industrial, commercial, and retail applications, Fiber Sensys has developped the FD322 Fiber-Optec Intrusion Detection Systems as an all-new fiber-optic perimeter sensor.
The FD322 incorporates Fiber Sensys’ proprietary and patent-pending technology that has been successfully deployed in thousands of sensors throughout the world, in a low-priced and easy to use sensor. Simply install the sensing fiber to the fence perimeter, connect the fiber-optic sensor to the alarm processor (APU) and select a few basic tuning parameters using the FD322 tuning software. That’s all there is to it.
The FD322 detects intruders attempting to climb or cut through fences. Sophisticated algorithms distinguish between intruders and “nuisance alarms” that might be caused by wind or small animals. Unlike metallic (coaxial) sensors, the FD322 uses advanced fiber-optic sensing that is unaffected by harsh environments, including UV radiation, moisture, salt, or even lightning strikes.


Return on investment – low in total cost of ownership.

The FD322 is the most economical and reliable fiber-optic perimeter sensor you can buy. Its economic advantage is found not only in the low purchase price, but also in its nearly nonexistent cost of ownership. The alarm processor will last for years, and unlike lower-quality systems, our fiber-in-conduit sensor will typically outlast the fence it is installed upon.
