Is it true that is there border control between sweden and norway based on the following text?

Both countries are members of the Schengen Area, and there are therefore no immigration controls. However, only Sweden is part of the European Union, so there are customs checks. These are performed by the Norwegian Customs and Excise Authorities and the Swedish Customs Service. These checks are sporadic along the Norway--Sweden border. Cars are usually not forced to stop. To combat drug smuggling, the use of CCTV surveillance has recently been increased, with systems using Automatic number plate recognition being rolled-out in 2016 and 2017.
