(Cincinnati, Oh.)--A retired college professor will spend the next six months in jail and have to register as a tier-one sex offender for 15 years after he was found guilty of hiding a camera at the Cincinnati Sports Club in Fairfax.

Brian Meadows, 76, a former professor at the University of Cincinnati, disguised the  live streaming camera as a European outlet adapter, captured video of three women and two children changing.

The recording device was discovered last November, in a changing room near the outdoor pool facility. Meadows was arrested days later and charged with multiple counts of voyeurism and illegal use of a minor in nudity-oriented material.
