Fiber SenSys manufactures fiber-optic intrusion detection solutions for a wide variety of markets, including military bases, airports, oil refineries, electrical substations, nuclear power plants, water purification, corporate headquarters and manufacturing facilities. These solutions have undergone rigorous testing by Sandia National Laboratories and the United States Air Force. Electromagnetic and radio interference, traffic, lightning and other common sources of nuisance alarms do not affect these systems. Installation is straightforward, using only simple hand tools, and the sensor systems require minimal maintenance. In addition to keeping intruders out, Fiber SenSys intrusion detection systems can be used to protect information. The SecurLAN system protects data flowing between computers through conduits and cabling, stopping potential security breaches. Fiber SenSys is a subsidiary of CompuDyne Corporation. Founded in 1952, CompuDyne is a leading provider of products and services to the public security market.
