A woman has told of her fury and revulsion at discovering her "sicko" half-brother had secretly filmed her, and other women, in the shower.

"He should have gone to prison, even if it was for six months, to be totally removed from society and he can absorb what he's done," said Sharon, who asked that her full name not be used.

"It's ripped our family apart. The only thing he's sorry about is that he got caught."

The Wellington man was this week sentenced to six months' home detention, 200 hours' community work and $30,000 reparation for filming people in the shower with a camera hidden in a wall socket and hooked up to a computer in his office.

His crime was discovered when one of the women he was living with was cleaning behind the oven and found a void full of up to 40 DVDs, labelled with women's names.

The court was told that the man had been living with his wife in Johnsonville.

Shortly before her two daughters moved in with them, he installed a hidden digital camera pointed at the shower.

He told his step-daughters the plug was blown and not to touch it.

Sharon said the man had been the baby of the family, smart and private-schooled. But his offending had gone on for 12 years and if the DVDs hadn't been found, he could still be doing it today.

The man was ordered to attend a psychiatric assessment, not to possess a computer, not to associate with people under 16 years, and not to associate with his victims. A protection order to stop him seeing his step-daughters was also issued.
