What OpenALPR is

A recognition system that reads vehicle plates and attributes from camera images and stores the results in a searchable database.

It is used where vehicle movement needs recording and later retrieval, such as car parks, campuses and traffic management.

What you can do with it

  • Recognise plate numbers automatically
  • Record vehicle colour, make and model
  • Build a searchable vehicle log
  • Manage access at entrances and exits

Who it is for
