Fence and Underground Perimeter Intrusion Detection

High-accuracy detection for perimeter fences and buried boundaries, unified with Genetec RSA Surveillance.

Nextro delivers advanced fence and underground intrusion detection systems that provide early, accurate warning of perimeter breaches, detecting cut, climb, or tunnelling activity before it reaches your facility. Designed for New Zealand’s critical infrastructure, these solutions combine Southwest Microwave’s INTREPID™ fence and buried detection technologies with Genetec Restricted Security Area (RSA) Surveillance for a unified, intelligent defence platform.

Intelligent detection at the perimeter

Nextro’s fence-mounted and buried detection systems use vibration and signal analysis to detect intrusion attempts with pinpoint accuracy. By analysing minute mechanical disturbances along a sensor cable attached to a fence or buried just below ground, the system can identify the exact location of intrusion attempts, while ignoring harmless movement from wind, rain, or wildlife.

This precision allows operators to locate and verify threats in real time, enabling faster and more confident response while minimising nuisance alarms.

Tailored to New Zealand’s high-security environments

These systems are typically deployed across airports, correctional facilities, utilities, energy infrastructure, defence sites, and logistics hubs, where secure boundaries are mission-critical. Built to withstand New Zealand’s diverse climate, from coastal zones to high-wind or industrial environments, the sensors are IP-rated and temperature-hardened, ensuring reliability in all conditions.

The platform’s Power-over-Ethernet (PoE) design simplifies installation, providing both power and data over a single network cable, reducing infrastructure and maintenance costs. Detection zones are easily configured through an intuitive browser-based interface, giving operators full control to adjust coverage or sensitivity as site requirements evolve.
