Using our fiber optic sensing solution you can detect intrusion and vandalism attempts already in the early stage giving you valuable time to take the appropriate action.
The monitoring system consists of passive optical sensors and an interrogation unit located at a remote site. The connection between unit and sensors is ensured via standard telecommunication optical fibers, e.g. dark fibers of an existing fiber optic network can be used. Our solution is most economical for a large area of monitored objects, which are not supplied with electricity.
The protection of your property and ensuring continuity of provided services can be a key issue especially in places without electricity or in hazardous areas where traditional ways of monitoring are very limited or almost impossible.
The sensor has been specifically designed to detect various methods of attacking protected structures and reject known environmental activity and potential false alarm scenarios.
What can be monitored?
- Door opening
- Vandalism

Technology
FBG – Fiber Bragg Grating
A fiber optic Bragg grating (FBG) is a method by which gratings transmitting/reflecting light of in advance set wave lenght are created at defined spots. Gratings can be implemented into fiber with different spaces between each other. The sensor is capable to intercept a change in the lenght of the grating and therefore measure changes of mechanical strain, deformation, pressure and vibration at discreet points of optical fiber. The technology allows connecting sensors in chains of different lenghts, it is also possible to monitor complicated and large structures at predefined places. FBG is most often used for Structural Health Monitoring.
