Using undetectable optical fibre and a compact interrogator unit, Fotech’s Helios system can protect 50km - and by integrating multiple Helios systems, any size asset can be protected from a single location. Typically, Helios detects personnel at 15m and vehicles at 40m either side of the sensor fibre. Helios integrates with PTZ CCTV and GIS mapping systems and can provide your security team with audio-visual corroboration and location details of an event or intrusion.
