About Fiber SenSys, Inc.

Fiber SenSys®, Inc., (FSI) is the market-leading manufacturer of fiber-optic intrusion detection systems for outdoor perimeters and physical data networks. FSI sensors have been successfully deployed on fences and alongside physical data networks at the most critical sites in the world. Our manufacturing and design headquarters are located just outside of Portland, Oregon, with sales and support offices around the world.

The company has a strong reputation for designing and manufacturing high-security, high-performance and high-reliability fiber-optic sensors. Solutions vary from those for protecting small, basic perimeters to those for highly-complex, large multi-site projects. FSI sells primarily to integrators who install and subsequently maintain integrated access control, video surveillance, and intrusion detection systems for facilities and end user clientele. In addition to product solutions, FSI technical services are available to both end-user and systems integrator clients. These services include product training, engineering support and design assistance, bill of material validation, onsite technical assistance and onsite commissioning.

The company has been a leading manufacturer of perimeter security solutions since its inception, with global installations of over six-million meters of fiber and the sale of more than fifteen-thousand alarm processor units (APUs). The company’s Fiber Defender® APUs have been evaluated and certified for U.S. military perimeters and government physical data protection. With the only high-security fiber-optic perimeter sensors to receive the US militaries’ highest rating, Priority Level-One Nuclear (PL-1N) for security at military/government installations, Fiber SenSys dominates the market.
