Mark Summerton will sign the Sex Offenders' Register

Mark Summerton and Kevin Judge, from Sefton Council, Merseyside, trained a street camera into the woman's flat.

At Liverpool Crown Court, Summerton, 37, of Kirkdale, Liverpool, admitted voyeurism and attempted voyeurism. He was sentenced to four months in prison.

Judge, 42, from Waterloo, admitted misconduct in public office and was jailed for two months.

He was cleared of voyeurism last month.

Summerton was also ordered to sign the Sex Offenders' Register.

You only have to read the impact statements of the lady to realise the harrowing effect this had on her

Team leader Vincent Broderick, 52, of Bootle, Merseyside, admitted misconduct in public office on the grounds that he did not see the woman when she was naked, but knew the cameras were being misused and failed to report it.

He was sentenced to 200 hours' community service.

The images from the camera, including the woman without her clothes on, were shown on a large plasma screen in the council's CCTV control room in November 2004, Liverpool Crown Court heard.

Over several hours, she was filmed cuddling her boyfriend before undressing, using the toilet, having a bath and watching television dressed only in a towel.

Judge Gerald Clifton told the three men: "To dismiss what was happening as laddish behaviour, something that the 21st Century apparently condones, is absurd.

"You only have to read the impact statements of the lady to realise the harrowing effect that this had on her.

"Her life has almost been ruined, her self-confidence entirely destroyed by the thought that prying male eyes have entered her flat."

During his voyeurism trial, Judge claimed he had only seen the woman naked for a brief moment and had told Summerton, who was controlling the camera, that he was "out of order".

The jury was satisfied but Judge Clifton said he did not believe this account.

He said: "I am amply satisfied that your involvement was larger than you are prepared to admit, that you were at some stage controlling the camera, and that you were watching and enjoying the events going on."

A Sefton Council spokesman said safeguards already in place meant the culprits were "caught and dismissed by us promptly".

"We will not tolerate an abuse of position from any of our staff or accept such a failure to meet the high standards of behaviour and professionalism we expect."
