FEATURES
FEATURES
Liminal-K offers ±6m precision in intrusion detection, ensuring pinpoint accuracy while minimizing false alarms. Each pole-mounted sensor is designed to reduce environmental vibrations, preventing unnecessary triggers. With configurable detection zones and adjustable sensitivity every 6 meters, security teams can fine-tune the system to match site-specific requirements..
Engineered to withstand extreme conditions, Liminal-K boasts an IP67 protection rating, making it resistant to dust, water, and harsh weather. Its robust construction operates reliably in temperatures ranging from -30°C to +60°C, ensuring year-round perimeter security in diverse environments.
Liminal-K is designed to integrate effortlessly with leading Video Management Systems (VMS) such as Genetec, Milestone, and Guetebrug, eliminating the need for dedicated software. With controllers that can be spaced up to 450 meters apart, infrastructure costs are significantly reduced while maintaining optimal coverage across large perimeters.
Beyond traditional intrusion alerts, Liminal-K is equipped with temperature and tilt detection sensors. It immediately senses heat changes caused by any attempts to burn or melt the fence, triggering an alarm. Additionally, it detects unexpected tilting or movement caused by strong winds or tampering, allowing security personnel to take timely action
Liminal-K’s compact and modular design makes installation quick and hassle-free. The system can be securely mounted using outdoor-rated cable ties without requiring specialized tools. Its modular sensor units can be replaced independently, ensuring easy maintenance and minimizing system downtime.
