Chevy Chase, Md. (WUSA9) -- A 64-year-old Chevy Chase lawyer and high-techentrepreneurhas plead guilty to secretly video recording tenants who rented rooms in his home.

Dennis A. Vandusen used a hidden camera disguised as a smoke detector to spy onunsuspectingyoung women and their partners during their most intimate moments.

Vandusen admitted to at least three incidents during 2011 and 2012. He also recorded through a window.

He was discovered when one of his victims noticed the smoke detector in her room did not chirp and blink like all the other smoke detectors in the home during poweroutagescaused by the Derecho storm in June of 2012.

Van Dusen faces sentencing in July, although his victims were shocked to learn such high-tech peeping is only a misdemeanor.

"The criminal justice system needs to keep up with technology," said one victim who does not want to be identified.

Vandusen used Craigslist to advertise for tenants in his $1.1 million dollar home on Ridgewood Ave. in Chevy Chase at surprisingly low rents, prosecutors say.

Van Dusen was released on $5000 bail pending his sentencing and ordered to stop renting rooms in his home.

"Not only did he steal these womens' privacy, he stole their peace of mind," said Ramone Korionoff, a spokesman for Montogomery County State's Attorney John McCarthy.
