A millionaire Sydney slumlord has been busted using his property to film his tenants naked and having sex.

Masaaki Imaeda, 66, already faced sentencing over owning a shanty town  made from shipping containers and derelict caravans where 15 people nearly died after a fire.

However, this wasn't enough to stop his deviant impulses.

He set up a network of mirrors and hidden cameras inside bedrooms at his other rental property, all linked to a garden shed.

Inside his lair was a reclining chair facing a big screen television and multiple laptops connected to SD cards, where he recorded and viewed his tenants for his own sexual gratification.

His sex den was discovered when a young married couple found an online warning that Imaeda was installing hidden cameras in his bedrooms.

They searched the room and found a camera hidden in the ceiling. A camera was also uncovered hidden in another room inside a television - facing the bed of a young female student.

He pleaded guilty to three charges of installing or using an optical device without consent, adapted to the fabric of a building - and three charges of observing a person in private without consent to obtain sexual arousal.

He faces three years in prison.
