MARIETTA, Ga. >> A Georgia man will serve time behind bars for filming himself naked inside his neighbor’s home after secretly installing a video camera in a bedroom.

News outlets report 58-year-old Michael Derek Roberts pleaded guilty Wednesday to burglary, invasion of privacy, criminal trespass and aggravated stalking charges. He was sentenced to three years imprisonment and 12 years of probation.

Prosecutors say Roberts, who knew his neighbors well, placed the camera inside their home while the family wasn’t there last spring. The neighbor discovered the camera and called police.

Authorities say Roberts told the neighbor he was testing a “nanny cam” at her house because his Wi-Fi wasn’t working. They say footage shows Roberts naked inside the neighbor’s closet and master bathroom.
