Frequently Asked Questions

What infrastructure can Norsensor monitor?

Norsensor solutions support monitoring of road infrastructure, tunnels, railways, power lines, perimeter security, border protection, and other linear assets using the same fiber optic sensing technology.

How does Automatic Incident Detection (AID) work?

Norsensor analyzes signals from existing fiber optic networks to automatically detect incidents such as stopped vehicles, wrong-way driving, queues, and other abnormal traffic events. Alerts are delivered to existing traffic management systems in real time.

Does Norsensor require new sensors to be installed?

In many deployments, no. The technology can use existing fiber optic infrastructure, reducing installation costs while extending the capabilities of already deployed networks.

Where is Norsensor technology used?

Norsensor technology has been deployed and evaluated in collaboration with public road authorities and infrastructure operators across the Nordics, supporting real-world monitoring in operational environments.

What is distributed fiber optic sensing (DFOS)?

Distributed fiber optic sensing (DFOS) transforms standard fiber optic cables into continuous sensors that detect vibration, acoustic activity, temperature, and movement along their entire length. This enables real-time monitoring of critical infrastructure without requiring large numbers of individual point sensors.
