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.
