The traffic wardens with eyes in the side of their head

But the traffic wardens of the 21st Century are bristling with technology.

They already carry digital cameras so they can take photos of cars before tickets are issued.

And now they are to have video cameras strapped to the side of their head.

These will gather movie evidence if angry motorists launch an attack and also help wardens in their new role of issuing penalties of up to £80 for anti-social behaviour.

They are now allowed to hand out tickets for such activities as littering, flyposting, graffiti and allowing dogs to foul the pavement.

The cameras, which are the size of an AA battery, are already used by police and community support officers.

A pilot scheme involving the new "robowardens" is being launched in Salford, Greater Manchester, and could be rolled out across the country if it proves a success.

NCP Services, the firm which deals with parking in Salford and 39 other local authority areas, says the technology will help protect its staff, who are often subject to abuse or physical assaults.

In addition, footage could be examined to ensure wardens did not overstep their powers and acted in a courteous and professional manner.

Communications manager James Pritchard said: "The cameras will be crucial in gathering evidence on the circumstances of why a fixed penalty has been issued.

"In many disputes it can often boil down to one person's word against another. We will now have the video evidence to help clear up any doubts."

He explained that a small number of workers would initially use the devices next week before the programme is rolled out to all parking staff working on behalf of Salford Council.

"We are hoping that other councils will decide to use the technology after seeing how well it works."

Derek Antrobus, a member of Salford Council, said: "We have 20 parking attendants walking around the city and we decided that they might as well look at more than just cars. One of the biggest issues on people's minds is the disrespect that some are showing to our environment.

"The police have not got the resources when they are chasing criminals so this makes a lot of sense."

Hugh Bladon of the Association of British Drivers said: "Where will it all end?

"There has been a perpetual erosion of liberty for drivers in this country and now we are to be filmed as well.

"I think it is disgraceful that we simply can't be allowed to get on with our own business without being continually harassed by this type of scheme.

"These cameras are another weapon to enforce outrageous parking fines and more. It is a stealth tax which is raking in millions for those involved and it is an outrage.

"With parking fines, road tax, speed camera fines and all the other penalties, maybe British motorists should just hand over all their cash each week and be given a small allowance."
