Perverted Steve Brookes, 55, known as telly’s Mr Rotavator in the 1990s, set up the motion-activated device on top of a cupboard.
The celebrity gardener – who has broadcast live from the Chelsea Flower Show – spied on a total of seven women between November 2015 and September last year.
They included lodgers living at his property and other people who had been invited to dinner.
Brookes, of Loxley Road, Stratford, pleaded guilty to seven charges of observing a person doing a private act knowing that the person did not consent to being observed for his sexual gratification.
But magistrates in Leamington Spa, Warks, committed the presenter to crown court for sentencing today.
He was given a 12-month prison sentence at Warwick Crown Court and will spend half of it behind bars and half on licence, reports the Coventry Telegraph.
He will also sign the sex offenders’ register for seven years.
