Securing tunnels and bridges is a field especially benefited from License Plate Recognition (LPR/ANPR). Survision Cameras such as Micropak 3 are capable to recognize dangerous goods transportation plates so operators can efficiently monitor special vehicles (HAZMAT carriers, for example) entering and exiting these structures and perform a faster and more accurate response in case of accidents.


LPR also gives operators the capability of surveying roads and tunnels for other security purposes:


  • Study of vehicles numbers on road networks
  • Vehicle counting in accidents
  • Monitoring of authorized vehicles


Connected to a Central Command Point, the Dangerous Goods (DG) cameras allow us to monitor daily traffic and provide information for a system of Automatic Detection of Incidents (ADI) or on a dedicated application such as AUTOFOCUS.
