A New Jersey man was sentenced to 15 years in federal prison today for using cameras hidden in a bathroom to take pictures of nine young girls in various states of undress.

Ronald Oshrin, 50, of Budd Lake, pleaded guilty in December to a charge of production of child pornography. Oshrin admitted to installing several hidden video cameras in his Morris County home in 2007. When the girls were in either the bedroom or bathroom, he monitored the cameras and recorded video of them disrobing, showering or using the toilet. Oshrin admitted he produced 85 graphic videos and over 1,000 still images and distributed them on the internet, according to court documents.

Oshrin, who was sentenced today in Camden federal court, also admitted to sexual contact with some of the girls, prosecutors said.
