An airline pilot hid a camera in a woman's bedroom without her knowledge.
Martyn Bourner, of Orchard Road in Port Erin, appeared before Deputy High Bailiff Rachael Braidwood at Douglas Courthouse.
The 34-year-old admitted trespass with intent to install a surveillance device in Port St Mary.
Recovered footage showed Bourner entering the bedroom and going through underwear and belongings before committing a sex act on her bed - other footage showed the woman and others.
The case was committed to the Court of General Gaol Delivery for sentencing, and he was bailed on condition he doesn't contact his victim to appear in court again on May 24.
