AI Is Redefining Perimeter Security
Seeing Is Not Enough: The Moment Before the Camera Matters Artificial Intelligence has significantly improved modern perimeter security. Cameras can now distinguish people from vehicles, detect unusual movement patterns, and prioritize alerts automatically. Instead of reviewing endless footage, operators receive filtered information. Still, one practical limitation remains: AI systems mostly interpret what they can see.… -

Continuous Perimeter Monitoring with Distributed Acoustic Sensing
Physical barriers have long been the default approach to site protection: fences, walls, cameras, and motion detectors. For years this was considered sufficient. Someone attempts entry, an alarm triggers, security responds. Modern facilities, however, face a different question — not whether an intrusion can be detected, but whether it can be detected before it actually… -

Fiber Optic Linear Heat Detection for Long Tunnels and Metro Systems
Fiber Optic Linear Heat Detection for Long Tunnels and Metro Systems Long tunnels and metro systems represent one of the most demanding fire safety environments. Confined geometry, limited ventilation, and high passenger density mean that even a minor overheating event can escalate rapidly. In these environments, the real question is not simply whether a fire… -

Pipeline Temperature Monitoring with Distributed Temperature Sensing (DTS)
Pipeline Temperature Monitoring with Distributed Temperature Sensing (DTS) In long-distance pipelines, the greatest risks often begin invisibly. A minor leak, insulation failure, or local friction initially manifests as a slight temperature change of just a few degrees. If these changes are not detected early, environmental disasters, production losses, and severe legal consequences become inevitable. Today,… -
