A trainee pilot has been caught sneaking onto a Sydney university campus and using a GoPro camera to secretly film a woman in the shower.
When detectives searched Jayden Collison's room at a hangar within the Bankstown Aerodrome precinct, they also allegedly found disturbing footage of two teenagers undressing in a changing room and dozens of child pornography videos.

The flight school student was arrested in December at the airport, where he had been living in a single room and studying to become a commercial pilot.
Despite being only 19 years old, he was already on a good behaviour bond for similar behaviour when he was arrested.

In March last year, he received an eight-month suspended jail sentence for filming a person in private without consent.
The Lithgow man is due to be sentenced next month after pleading guilty to the most recent five offences, including for breaking into university accommodation and filming women without their consent.
The offences came to light when police went through Collison's MacBook Air and found GoPro footage files on his desktop.
Two videos showed a woman showering in a villa on the Western Sydney University Milperra campus in December, according to a statement of facts tendered in Bankstown Local Court.
Collison initially denied having been to the WSU campus or knowing where it was located.
During a police interview, detectives asked him to explain why his car was on CCTV footage at the university.
Collison claimed his number plates must have been removed from his car.
It wasn't until the end of the interview that he admitted it was him in the campus footage and that he "didn't want to go to jail".
When he was questioned about the whereabouts of the GoPro footage showing the woman in the shower, Collison initially told police: "There is no footage I swear, I wasn't recording."
Another video file police found showed Collison's face on the footage before the camera was slipped into a change room in a shop where two girls, aged between 13 and 14, were in a "state of undress".
Court documents state that another 40 videos depicting child abuse material, including "pre-pubescent boys and girls engaged in sex acts clearly against their will", was also found on Collison's laptop.
Collison also pleaded guilty to breaking into a WSU student villa and stealing a key about the time he recorded the young woman showering.
Police claimed that at "no point during the investigation did the accused assist police or show remorse for his actions".
Collison will be sentenced on March 1 in Bankstown Local Court.
