GridCop® is the first, field-test proven, powerless remote optical sensor family system to monitor networks, grids and critical infrastructures over short to long distance: from manholes to ducts, cable troughs, splice boxes, distribution frames, street cabinets, containers, gates, wells, reservoirs, tunnels, masts, etc., GridCop® can be used in a virtually endless number of applications, ranging from commercial to institutional, from civil to military – everywhere where reliability and “stealth” characteristics are at stake.
