Bryce Fogg appeared in court Wednesday on charges of secretly recording a girl and a woman as they undressed while working as a gymnastics coach.
A Douglas County judge set his bond at a half-million dollars.
Prosecutors believe the 27-year-old took inappropriate recordings and photos of a teen girl and woman while they changed at Premier Gymnastics.
The allegations came to the forefront once an ex-girlfriend went to investigators to claim she found disturbing photos and videos on his iPad.
Felony charges include two counts of visual depiction of sexually explicit conduct and one count for unlawful intrusion by recording.
Authorities booked Fogg here recently after being extradited from Kansas, where he was arrested last month.
