Germany is angry at plans by the Netherlands to hang cameras at border crossings, which will record the number plates of cars crossing into the country, Nos television reports.

Germany says the plan conflicts with European free movement principles and has made a formal complaint to the European Commission.
The cameras are currently being tested at several locations but the Netherlands plans to formally install them at 15 border crossings in January.
According to Nos television, the camera system alerts the border police to vehicles it would be worth controlling. This could be a car listed as stolen or a type of van often used in people smuggling, Nos says.
