Sanral recently posted a video on Twitter showing how it uses its cameras to track criminals. Over to BusinessTech:Sanral said that the cameras used form part of Sanral’s Freeway Management System (FMS) used to manage traffic flow and incidents on strategic national roads. This was picked up from the closed-circuit television cameras used to monitor major roads in Gauteng, KwaZulu-Natal and the Western Cape, he said. Here it is, with surprisingly decent video quality:Two armed hijackers caught by Sanral cameras. It’s a pity they weren’t captured by the Sanral cameras.
