About Liminal-K

Liminal-K is an advanced fence vibration detection system that transforms any perimeter into a proactive defense mechanism. Designed to detect climbing, cutting, or tampering with pinpoint precision, it delivers real-time alerts to stop security breaches before they escalate. Powered by MEMS (Micro-Electro-Mechanical Sensor) technology, Liminal-K offers accurate intrusion detection with multi-layer redundancy at the sensor, controller, and network levels, ensuring uninterrupted monitoring. Its compact, discreet design makes it difficult for intruders to spot, while its ability to integrate with leading video management systems makes it a seamless part of modern security ecosystems.

Whether deployed on rigid weldmesh fences, or walls, Liminal-K offers intelligent, reliable, and adaptive protection for critical infrastructure, high-security facilities, and sensitive perimeters.

Liminal-K Working

The Liminal-K fence vibration sensor employs a highly accurate fence vibration detection system to locate cutting, tampering, or climbing attempts. It offers actionable alerts to secure areas before cutting, climbing, or tampering occurs. Its anti-climb vibration sensor technology provides an additional proactive security measure to any perimeter.

Features

High Detection Accuracy & Low False Alarms

Liminal-K delivers ±6m pinpoint accuracy, allowing security teams to identify the exact location of intrusion attempts. Configurable zones and adjustable sensitivity every 6m minimize nuisance alarms, ensuring that real threats are never missed. Pole-mounted sensors help filter out environmental vibrations, keeping the system reliable and noise-free

Advanced Redundancy

Security is guaranteed even during failures. Liminal-K features overlapping sensor coverage, cable cut protection, and Forward Error Correction (FEC) backup at the controller level. These multi-layer redundancies ensure continuous intrusion monitoring even during power or network interruptions.

Optimized MEMS Technology & Easy Installation

Liminal-K leverages MEMS sensor technology for superior detection. Installation is simple, requiring only outdoor-rated cable ties — no special tools or extensive civil work needed. This makes it a plug-and-secure solution with faster deployment times.

Single Sensor for Complete Coverage

One Liminal-K sensor can detect disturbance in fence posts, panels, and concertina coils at the same time, eliminating the need for multiple systems. This reduces hardware costs while providing comprehensive perimeter coverage with just one solution.

Cost-Effective & Seamless Integration

With controllers spaced up to 450m apart, infrastructure requirements are reduced, lowering project costs. No dedicated software is required — the system integrates directly with leading VMS platforms such as Genetec, Milestone, and Geutebrug. Integration with PTZ cameras provides a complete intrusion detection and video verification ecosystem.

Pinpoint accuracy

This advanced fence vibration detection system can locate the exact point of intrusion, offering precise detection. Liminal-K's accurate vibration detection alarm helps security personnel respond swiftly to any breach along the perimeter
