Physical Security & Asset Protection Solutions

Revolutionizing Perimeter & Asset Security with 360° Fiber Optic Sensing

Fiber optic sensing delivers seamless, real-time security above, on, and below the surface—covering rooftops, perimeters, access points, and critical infrastructure for complete situational awareness


A TRUE SPHERE OF DEFENSE FOR THE MODERN ENVIRONMENT

Fiber optic sensing technology transforms the way organizations secure their most critical facilities. By turning the fiber itself into the sensor, protection can extend underground, along fence lines, across rooftops, manholes and equipment cabinets – even monitoring temperature shifts in environments like power busways and tunnels. This creates a seamless, three-dimensional shield around your assets—delivering continuous, real-time intrusion detection whether a threat is approaching, breaching, or already inside the perimeter.

Traditional security tools alone can’t keep up with today’s threats. Effective protection requires a multi-layered, proactive approach that closes gaps and provides visibility above, on, and below the surface.

With NIS’ SENTINEL™ Perimeter and Asset Protection Solutions and the INSIGHT™ Alarm Management Platform, Network Integrity Systems delivers actionable intelligence that stops threats before they escalate:

  • Comprehensive Coverage – Deploy along fences, walls, rooftops, and underground for a continuous, invisible layer of defense.
  • Rooftop Intrusion Detection – Identify climbing, access attempts, or unauthorized presence above the line of sight.
  • Fast, Scalable Deployment – Install quickly for permanent facilities or temporary high-risk events.
  • Real-Time Alerts – Get immediate notification of suspicious activity to enable rapid response.
  • Seamless Integration – INSIGHT integrates with video, access control, and command platforms for unified situational awareness.
  • Adaptive Reliability – Self-tuning technology minimizes false alarms, even in challenging weather conditions.
  • Smart Event Processing – Advanced analytics deliver accurate, actionable alarms.

From open-air venues and corporate campuses to critical infrastructure, data centers, and government facilities, SENTINEL™ empowers security teams to move from reactive response to proactive defense. By covering rooftops, perimeters, access points, and even monitoring temperature shifts in environments like power busways and tunnels, it establishes a true sphere of protection—keeping people, assets, and operations secure before a threat materializes
