Ronald Oshrin of Budd Lake will also have to serve 10 years of supervised release once he's freed from prison. He was sentenced on Monday.

The 50-year-old Oshrin had pleaded guilty to producing child pornography.

Prosecutors say that between 2007 and April 2012, he installed hidden cameras in a bedroom and a bathroom of his home in order to record nine young girls in various states of undress. They say Oshrin edited the videos to produce still photographs and distributed the videos and the still photographs over the Internet.

He also admitted to sexual contact with certain minors.
