Thirty nine-year-old Stephen Edwards was arrested last July after builders told police they had discovered a video in his home featuring children having sex with adults.
Edwards, who admits a "voyeuristic interest" in child pornography, later pleaded guilty to five charges of making indecent photographs of children under the age of 16 from the internet after a police raid on his home revealed 22,700 indecent images stored on his computer and other equipment.
In his defence, Edwards' lawyer argued that his client had not distributed any of the images, nor gained financially from his offences, and urged the court to take into account that he had never been in trouble with the police, apart from a conviction for drunken driving some years ago. He added that Edwards had since disposed of all his computer equipment and was taking counselling for his problems.
However District Judge Rosamond Keating called the case "one of the worst of its kind" to come before her court, and said her powers of punishment - a maximum of one year's imprisonment - were "insufficient" to deal with such a serious case. She then ordered Edwards to be sent in custody for sentencing at the Middlesex Guildhall Crown Court.
