The Guardian Fence System by Payne is an interlocking modular security perimeter and segregation fence system composed of rigid metal mesh materials. The design provides trenchless integration of tamper-detection, communications and security-lighting systems. Fiber optic and cabling components are shielded from weathering and vandalism with the system’s steel rails. The system can incorporate restrictive components, such as barbed-tape concertina and cable-based anti-crash elements.
