The LIMINAL-K (a vibration sensor) is an in-house development of A-1 Fence. It is an active intrusion detection device that detects vibrations on different types of fences with high accuracy at up to 3 metres. These fences include ClearView mesh, steel palisade, concrete palisade, and precast walling.
The design has the sensors fitted to the posts and pillars to ensure low to no nuisance alarms. The installation is simple and quick and there is no maintenance needed on the system, so no maintenance budget is required. The system is rated IP67 with strong, durable cables, potted electronics, and built-in surge protection.
The supplied software is easy to navigate and set up, with a live map to show detections and that the sensors are online. When an intrusion is attempted on the fence, the zone with the nearest sensor will pop up on the screen to indicate the exact location of the attempt.
Integration into a CCTV system to view or record can be done, along with triggering lights, setting a siren off and linking to an alarm system. The company currently offers integration into Milestone and Genetec VMS.
With no corrosion, mist, fog, rain, insects, animals, direct sunlight or reflection issues, Liminal-K is the product to reduce your nuisance alarms and adds to your layered requirement.
