London trials ‘no-flash’ stealth speed cameras
Fri, 27 Mar 2026
Transport for London is trialling a new type of speed camera that doesn’t flash when speeding motorists drive past.
They also don’t require any road markings or in-ground sensors.
The high-tech new cameras use 4D radar and a 4K colour camera to detect the speed of passing vehicles. They can cover up to five lanes of traffic — and a single camera can capture traffic in both directions.
The new ’stealth’ speed cameras can also capture distance, elevation and direction. TfL says they will be more reliable than traditional cameras and produce better quality images.
They will be trialled at up to 10 sites across London. They will be installed over the next few weeks in Haringey, Tower Hamlets, Havering, Croydon, Hammersmith and Fulham, Brent, Hackney, Ealing and Sutton.
TfL says all sites are on 20mph or 30mph roads, and “have been identified on the basis of suitability and risk”.
Around half of fatal collisions in London in 2024 reported speed as a contributory factor, says TfL, and “excess speed remains one of the biggest risks to road users.
“This trial allows us to test new radar-based camera technology to ensure it meets London’s future enforcement needs,” says TfL’s Siwan Hayward.
TfL is working in partnership with the Metropolitan Police Service (MPS) on the roll-out.
“This trial will improve reliability and deliver better quality images,” added Detective Chief Superintendent Donna Smith, “helping our officers hold offenders to account and ensuring we have a modern and effective enforcement system that saves lives.”
TfL told the BBC there is no fixed period for the trial and it would continually assess the results.
The cameras, made by RedSpeed, are called the RedSpeed Sentio Shield system.
Because the images produced are such high quality, they can also detect drivers using ‘ghost plates’ – the 4K images allow both number plates and drivers to be clearly identified.
