Protecting Critical-Infrastructure

Perimeter defense is essential for preventing disruptions at high-value sites. OPTEX offers intelligent sensing technologies that establish virtual boundaries around fence lines, restricted zones, and facility entrances. REDSCAN LiDAR sensors form invisible detection walls with precise zone configuration and object filtering, reducing false alarms while providing reliable coverage. For wide, open areas or long-range fence lines, active infrared beam sensors deliver point-to-point detection that withstands harsh environmental conditions. These solutions enable early alerts before a threat reaches vital infrastructure.

Proactive monitoring of the area outside the perimeter helps stop threats before they reach critical infrastructure. OPTEX REDWALL SIP sensors provide wide-area coverage for approach zones, open substation yards, or exposed corridors, triggering alerts when unauthorized movement is detected in vulnerable areas. These high-performance outdoor PIR sensors offer detection ranges of up to 330 feet and are engineered to maintain accuracy in adverse weather conditions. By extending the site’s detection footprint, they provide valuable time for response before a breach occurs.

Securing building exteriors is essential for preventing intrusion through less-visible access points such as rooftops, upper windows, or structural facades. OPTEX REDSCAN LiDAR creates configurable vertical or horizontal detection zones that can monitor large, flat surfaces and roof structures without disrupting architectural aesthetics. These discreet sensors are ideal for sites requiring low-visibility, tamper-resistant protection. With remote configurability and long-range coverage, REDSCAN sensors adapt easily to complex layouts and evolving threat scenarios.

Once an intruder is inside, every second counts. OPTEX indoor sensing solutions provide fast, accurate detection to protect mission-critical rooms, hallways, and restricted compartments. The FlipX Advanced features a unique rotatable lens, allowing one sensor to handle both wide open areas and narrow corridors with tailored precision. For high-security environments, REDSCAN indoor LiDAR forms invisible detection zones that trigger alerts when breached. These technologies work together to guard sensitive operations from within, adding depth to any layered security plan.

Traditional access control systems can be bypassed if multiple individuals enter under a single authorization. OPTEX’s Accurance OV-102 Anti-Tailgating System reinforces physical access points using advanced human-tracking and direction-detection technology. It identifies tailgating, cross-entry, and multiple occupancy in real time, ensuring compliance with strict entry protocols and minimizing insider threats. Designed for critical applications like control centers or data rooms, the system integrates easily with existing access control infrastructure to enforce one-person-at-a-time access.

With increasing threats to physical infrastructure, substations must comply with NERC’s CIP-014 regulations to ensure grid stability. OPTEX provides detection technologies that help utilities meet these requirements with early-warning intrusion detection, scalable coverage, and system flexibility. From REDSCAN LiDAR and REDWALL PIR to active infrared beams, these solutions support layered defenses that can be customized to match each site’s threat profile. By reinforcing critical points of vulnerability, utilities can improve resiliency and maintain uninterrupted service.
