An intelligent perimeter intrusion detection system designed to sense disturbances, generate alerts, and support timely security response.
Most perimeters are designed to deter intrusion, but no physical barrier is impossible to cross. What matters is knowing when an attempt is made, and where it’s happening. Liminal-K is a fence mounted intrusion detection system that senses disturbances on fences and walls, generating real time alerts when intrusion attempts occur.
Built on MEMS-based sensing technology, the system detects kinetic energy caused by cutting, climbing, or impact, helping identify intrusion attempts with a high degree of accuracy. Each sensor covers up to 32 feet (16 feet on either side) and can pinpoint the location of disturbance, allowing security teams to respond quickly and effectively. With adjustable sensitivity, Liminal-K can be tuned to site conditions to reduce false alarms, making it suitable for a wide range of perimeter environments.

When an intrusion attempt occurs, Liminal-K detects the disturbance and triggers an alert. The system communicates with the Sensor Master, which relays the information to monitoring software, allowing operators to identify the exact location of the event. The system can also integrate with video management platforms, automatically cueing cameras to the intrusion point for visual verification. This creates a connected workflow:

Liminal-K detects intrusion attempts directly at the perimeter by sensing cutting, climbing, or impact. This allows security teams to receive real time alerts and respond before a breach is completed.
