Forty-three-year-old Michael Scheeler told a Lehigh County judge he was "rebelling against God" because of problems in his personal life when he secretly recorded seven teens inside his Lower Milford home.
Investigators say five of the teens were foreign exchange students, four from Korea and one from Spain. Three of the Korean students lived with Scheeler and attended Faith Christian Academy, where Scheeler volunteered.
Authorities say one of the students saw the videos on Scheeler's laptop and alerted an administrator at his school. Police located the recording equipment in a subsequent search.
Scheeler pleaded guilty in May to charges including possession of child pornography.
