Philadelphia ? A suburban Philadelphia landlord secretly videotaped 34 female tenants over two decades after hiding cameras in their apartments, authorities said Friday.

Thomas Daley, 45, was arraigned on more than 2,000 charges by Magisterial District Judge Francis Lawrence Jr. and waived his preliminary hearing Friday.

Authorities had not previously disclosed the number of tenants involved.

Daley had installed the cameras – typically one in the bedroom and one in the bathroom – in at least 7 apartments he rented to women in Norristown over the last 19 years, Montgomery County Assistant District Attorney Coley Reynolds said Friday.

Daley’s sophisticated set-up fed the camera images to a recording system in the basement, enabling him to view the tapes from his home via the Internet, authorities have said.

He hid the tiny cameras behind mirrors and in cabinets and ceiling fans, and some turned on with the flip of a light switch, they said.

Defense lawyer Timothy Woodward did not immediately return a message Friday.
