City council leader Gerald Vernon-Jackson is convinced that just seven fixed cameras dotted around Portsea Island are not sufficient – and we have to agree with him.
For a start, they are positioned on main roads so do absolutely nothing to stop drivers speeding through residential areas where the limit is supposed to be 20mph but is not enforced.
Secondly, drivers know full well they won't be caught on all those other arteries where there are no cameras. That breeds complacency and, in the absence of any deterrent, the temptation is to speed – even if it is breaking the law.
So what is the answer? Cllr Vernon-Jackson thinks it's time to get rid of the fixed cameras and switch to a system of mobile cameras that can pop up anywhere to catch people unawares.
His idea is to take the £380,000 annual funding currently given by the council to the Safer Roads Partnership and hand it to the police to pay for officers with mobile units to take to the streets.
The reasoning is simple. As Cllr Vernon-Jackson says: 'People thinking that the police are out and about everywhere doing speed checks would be a far better deterrent than a camera.'
He's right. If drivers didn't know where the cameras were, they would be far more likely to stay within the speed limit at all times.
Town bosses in Swindon have already threatened to stop funding a Safety Camera Partnership and look for more cost-effective ways of spending the cash.
Now Cllr Vernon-Jackson is meeting with road safety police this week to discuss what could happen here.
There are questions still to be answered, such as the cost and availability of police manpower required to cover the city with mobile camera patrols.
But if those officers can be found and paid for, then it has to be more effective than the present system.
