English to Dutch Law/Patents Law: Patents, Trademarks, Copyright

I need help with the translation into Dutch of the phrase ´circumvention devices´in an instruction manual for customs. The document is about tell-tale signs of counterfeit products. In this document the term is defined as follows:

´Circumvention devices, commonly referred to as game copiers, R4s, flashcards, and linkers are devices which bypass the security [this company] uses and allows pirated games (downloaded from the internet) to be played on the handheld consoles´

Target audience are Dutch customs officials
