There's word going around about a new kind of speed camera hidden in the central crash barrier. I thought that the law had been changed a few years back so that all cameras had to be conspicuously marked with fluorescent orange panels and that warning signs had to be installed at a prescribed distance. Does anyone know anything about these?

Not sure on this one, perhaps Stoney can shed some light on this.

As far as I'm aware though they don't need to display speed camera signs but the speed limit must be clear and well sign posted...

I've seen this reported on Twitter and the like, and it is always debunked as a hoax.

Every report I've seen uses the exact same photos you have posted.

See this German website from *2007* (which also declares them as a hoax)

Same pictures....

I just googled for "crash barrier speed camera" and everyone says its a hoax. But like most Internet rumours, it just won't die.

Not licenced for use in the UK, not being trialled in the UK, not planned for introduction in the UK.
Don't worry.

Problem solved lol

It would cost too much to install as there is rarely anything to connect these to along a central reservation. Imagine the work required in supplying power and network links. I doubt we would ever see these here.

Ok, thanks for the clarification (especially Stoney).

there does have to be camera warning signs doesnt there? ..thats why they're all over the place, just so in the event a van pulls up you cant complain

and im not sure but dont the majority of cameras get you from a distance then snap a pic of the number plate when you pass? ..meaning it doesnt matter whether you see them or not, its too late!

See above - this is a hoax that was first found in Germany in 2007. The pictures are the same.

Without markings also on the road and its low height it would not be possible to calculate the speed from photographs taken by the camera.

I'd be lucky to get a Christmas cup of tea.

Surely the front-facing cameras (can't remember their name) don't use road markings and can calculate speed directly from the doppler measurement so presumably these barrier-mounted ones operate on the same principle.

I believe you mean the Truvelo system?

Truvelo Speed Cameras

The forward facing Truvelo camera system is designed to take photographs of the front of a passing vehicle, this allows the picture taken to show the driver of the vehicle as well.

To avoid the 'flash' which is given out by a rear facing Gatso camera the Truvelo system uses an infra red flash which produces no visible 'flash' to the approaching driver. These rely on 3 white-lines in the road, painted just before the camera, and are triggered by strips in the road, used to gain the vehicles speed.
