Saunas can't make use of security cameras in rooms where guests are walking in their birthday suits, warns the Dutch Data Protection Authority (AP). The AP sent a letter to several saunas following complaints. According to the AP, filming nude individuals is a "huge infringement on privacy" and only appropriate in exceptional circumstances. Prevention of sexual acts or theft doesn't suffice. Camera images that are watched right then without retention are not allowed either. People must be free of spying in these rooms, the AP states.
