Cheryl Higgs has set up a website at www.nocameraphones.org calling for better management on the use of camera phones in childcare settings.
Ms Higgs said she did not want to ban camera phones, but to bring in legislation to restrict the use of camera phones in a nursery environment.
She suggested that this could mean that staff are required to keep their camera phones in a locked office or staff room which they can only access in their breaks.
Last month nursery worker Vanessa George, 39, who worked at Little Ted's nursery in Plymouth, was charged with sexual assault and making, possessing and distributing indecent images of young children.
Police believe that the images were taken of children at the nursery. They seized a mobile phone and computer equipment (News, 18 June).
The case has brought into question policies and procedures at nurseries to safeguard children, including the routine use of digital technology to record children's progress.
Ms Higgs said, 'After the shock, anger and crying of the first few weeks after the Little Ted's news broke, I decided to do something to prevent this kind of thing happening again.'
Ms Higgs is calling for pre-schools and nurseries to join her campaign to help establish legal guidelines for the use of camera phones in early years settings.
She claims that 23 nurseries in Devon and Cornwall have signed up to the 'no camera phones' policy so far.
Plymouth City Council said it would shortly be issuing a written policy for nurseries and other early years settings to fit in with the council's policy on taking photographs and making videos.
The council said that the early years team were revising guidelines and that any guidance issued would be available for private and voluntary nurseries, but that it was up to PVI providers to decide how to implement guidance in their settings.
A spokesperson for Plymouth City Council said, 'The recent incident at Little Ted's gave us the opportunity to remind all nursery settings about best practice in relation to various safeguarding matters. This included advice on the use of cameras and a clear recommendation that mobile phones be kept in individual lockers or trays where staff might secure other personal belongings or valuables. All of the nurseries, without exception, responded very positively to this.'
