A man trying to imitate "things he saw on the internet" hid cameras in the toilets at the care home where he worked.
Joshua Knights-Taylor, 23, filmed multiple women in secret until he was finally caught out.
Knights-Taylor, of St Asaph, confessed to a charge of voyeurism at his former workplace during an earlier court hearing held in March, North Wales Live reports.
He was put before a judge after arriving to court late on May 19 for his punishment.
Mold Crown Court heard that between June and December 2021, Knights-Taylor worked as a care home assistant at a facility in Denbighshire.
Prosecuting, Dafydd Roberts, said it was here that a mobile phone which had been placed in the toilet block and had been filming those using the facilities was discovered by another member of staff.
Knights-Taylor was confronted about the finding and "immediately" confessed to being responsible. He was arrested and interviewed on New Years Eve where he made "full and frank admissions".
Mr Roberts told the court how the defendant had already prepared a written confession, stating: "I did it because I was dirty".
The former care worker went on to say how he "wasn't thinking straight" and admitted he'd been running the camera "for a few months".
The device was examined by the police who found videos from three different toilets between the six-month period. In that time, 37 videos were recovered that identified a number of female staff members and even a resident of the care home.
Knights-Taylor would set the device up at the start of his shift and collect the mobile phone before leaving.
The prosecutor said one of the women caught on Knights-Taylor's secret camera has since quit their job. Others, who say they felt "violated and betrayed" are still considering if they'll do the same.
Defending, Patrick Geddes, told the court how his client was a young man now facing a "very serious sexual offence". He tells the court how Knights-Taylor has struggled with his own mental health and sexual identity in the past but says this "in no way" an excuse for his actions.
Mr Geddes says that Knights-Taylor explained that he sought to imitate "things he saw on the internet" and that the "end goal was sexual gratification".
He adds that he's then been "unable or unwilling to stop" and was simply "waiting to be caught".
The consequences of these actions will "follow him around for some time", the court heard. Mr Geddes said that the judge has as "stark choice" before him in how Knights-Taylor will be punished.
Judge Niclas Parry branded it a "campaign of voyeurism" when jailing Knights-Taylor for 10 months. He added that his plot took a "significant degree of planning" to make it a reality.
He said: "You've admitted to an offence that would outrage and disgust any right thinking person. Over a period of six months, when you were employed at a nursing home, you abused your position repeatedly by placing a phone within the staff toilets of the establishment."
The judge explained how the women he filmed had all given statements, confirming that he caused "an enormous amount of distress". His actions left people feeling unsafe in what was either their own home or place of work.
