According to police, two people had been invited to stay at a friend's apartment in the George Street and The Esplanade area while he was out of town. They noticed "a number of hidden cameras" and contacted police.
It's alleged that photographs and videos were taken of people who stayed in the apartment, including some taken in the washroom.
The 61-year-old accused is charged with four counts of voyeurism. He is due to appear in court on Tuesday.
