MARKETS WE SERVE: Data Centers, Nuclear Power Plants, Government/Military, Underground Utilities, Universities, Medical Campu ... s Sites APPLICATIONS WE PROTECT: Manholes, Handholes, Radioactive Source Enclosures, Gates, Culverts, Doors, Junction Boxes, Underground Pathways, Perimeter Vehicle Detection, Storm Drains Our system provides monitoring of remote access points and perimeters using a family of sensors and cables developed and made by LightLOC. Monitored items can include manholes, gates, doors, underground pathways, perimeter vehicle detections, and custom applications. Monitoring is possible at distances of up to 30+ km without the need for electrical power at the monitored locations. The robustness of the system eliminates false alarms commonly seen with other fiber-based security systems. Our systems are inherently tamper resistant since altering or destroying optical components triggers alarms automatically. read more
