VIDEO SURVEILLANCE SYSTEM ON THE RIJEKA - ZAGREB MOTORWAY (CCTV - Closed Circuit Television) The use of the video surveillance system (CCTV) on the Rijeka - Zagreb motorway dates back to 1996 when the so called “Snow Section”, passing through Gorski kotar, was opened to traffic, i.e. when the link was established between the Oštrovica and Vrata interchanges.
