A "sexual predator" who committed a catalogue of crude offences against women has been jailed for eight-and-a-half years.
Pawel Relowicz, 25, left his victims feeling "violated" and "terrified" after watching some of them commit intimate acts and stealing sexual items from their homes.
A court heard how the Polish butcher's "odd and worrying" behaviour included pleasuring himself in the street.
He was due to stand trial at Sheffield Crown Court on Monday charged with 13 offences, but instead admitted four counts of voyeurism, three of burglary and two of outraging public decency, with the other four offences left to lie on file.
The defendant, wearing a grey sweatshirt, appeared to be on the verge of tears as he was told the length of his jail term on Friday.
Passing down the sentence, Judge Jeremy Richardson QC told him:
"Between June 2017 and January 2019 you indulged in a campaign of crime.
"I am certain that each one of your crimes, including the burglaries, was driven by your perverted sexual deviancy.
"I cannot ignore the fact that you are plainly a sexual predator."
Relowicz was also given an indefinite Sexual Harm Prevention Order.
Describing the sentence as severe, the judge said: "It is intended to be so as this form of criminality is very serious and the public have the right to be protected from an individual like you."
He added that it was clear that the offences had been motivated by Relowicz's "perverted sexual deviancy", and described him as potentially being a "very dangerous individual".
"It is clear to me that you harbour sexually deviant traits within your character", the judge added.
