Mobile Ulez cameras are being protected by dedicated security units in a bid to stop vandals.
Footage was shared on social media of an activist approaching a man and a woman sitting in a red Renault Clio and asking if they were security, prompting one of them to nod.
The activist then says that there were two of them and this was public money, and that they were just keeping an eye on it to make sure no one smashes it.

In response, the male guard shook his head. A newspaper outlet has contacted Transport for London, which operates the Ulez scheme, to ask whether security teams now protect all mobile Ulez cameras.
Vandals were out in force, with images from Dartford, southeast London, showing a set of traffic lights equipped with a Ulez camera that had been knocked over onto a pavement.
London Mayor Sadiq Khan defended the controversial policy during a UN climate summit in New York by describing it as the best ever two-for-one offer, adding that the same things that cause climate change cause air pollution.

He said, that nitrogen dioxide, nitrogen oxides, particulate matter and carbon emissions. If you deal with one, you deal with the other. But Liberal Democrat leader Sir Ed Davey said Sadiq Khan’s measures were not proving effective.
He told BBC London that the problem with the mayor’s plan is that it does nothing for climate change, and was actually very poor air pollution and that it was costing the people a fortune.
Neil Garratt, leader of the Conservative group in the London Assembly, said that he was alarmed to hear the mayor claim that expanding Ulez would cut carbon emissions. He said that it wouldn’t and he knew that because his own report spells it out, so why was Sadiq Khan claiming otherwise at the conference?

The Mayor expended Ulez to cover the entirety of London several weeks ago, clobbering thousands more motorists with the £12.50 day-to-day charge.
Footage emerged of a protester climbing a ladder to block a camera on top of a Transport for London van on Rainham Road in east London, with locals rallying around the man, with one writing on Facebook: ‘Let’s hear it for the lad sitting on the ladders blocking the Ulez camera on Rainham Road. This made my morning, power to the people.’
Elsewhere in Ickenham, in the borough of Hillingdon, vigilante vandals sprayed foam used for filling cracks and insulating lofts over two cameras, stopping it from catching motorists.

How much is this boneheadedness costing the taxpayer? Evidently, there’s no fixing stupid!
Sadiq Khan said it was a great two-for-one offer as it tackled both air quality and climate change. In that case, why didn’t he attend the conference in New York by video link? Without a doubt, his words don’t match his actions.
Could it be that it’s because green issues are an excuse, and that Ulez is about raising money and the New York trip was about spending money on a wonderful work jolly?
This is all coming out of the taxpayer’s money, which is our money, and who gave Sadiq Khan a license to waste it? These people guarding the cameras must have an extremely low moral threshold.
This is what dictatorship looks like folks!
And how did Sadiq Khan get to New York to do his address? Did he grow some wings, not of course not, he flew by aircraft. What does he think that an aeroplane doesn’t emit pollution? What fantasy world does he live in?
