geelhoed Posted April 21, 2006 Posted April 21, 2006 You guys are lucky. They paint them yellow over there. Strategy here is to hide them, parked undercover cars, garbage cans and policemen with laserguns. In addition there are socalled "traject controls" measuring the time a car takes over a known distance and automatically registering the plate and sending the bill. I pass three of these sections when I drive the 60miles to my parents. You guys are lucky. Quote
Man On The Clapham Omnibus Posted April 21, 2006 Posted April 21, 2006 The Truvelo on the Rye in High Wycombe certainly flashes visibly, I've seen it do it. Infra-red floodlights for cctv are visible to the human eye but at much reduced intensity to the amount of 'light' that they emit. They look like a deep red coloured PAR38 flood - like a heat therapy lamp. Given that a flashgun is very bright normally, it isn't surprising that a xenon flash with an IR filter is slightly visible to the eye. BTW geelhoed, we have the traject type of system here but it's called SPECS. Quote
geelhoed Posted April 21, 2006 Posted April 21, 2006 oh I didn't know. You guys aren't so lucky afterall. Quote
pistonbroke Posted April 21, 2006 Posted April 21, 2006 I have two pairs of SPECS 1 for reading 1 for watching telly Quote
Liam Posted April 21, 2006 Author Posted April 21, 2006 The Truvelo site is very interesting. It would appear that if a forward facing Truvelo 'flashes' at you then it is a dummy unit and intened to scare you, but the real ones are infra red. I know for a fact the the ones outside the factory have been live, because I have seen people changing films, etc and a factory supervisor also got busted in a Managers car... So they are obivously changing the unit between dummy and live as well. This page, Secondary Speed Checks, was the most intersting bit, I have always wondered what they use the 3 little white lines for! So, I may have been right after all. They do emit a flash in certain circumstances. The 'dummy' bit stacks up as I never heard anything form the one I triggered in Beds. I have noticed that the forward facing Truvelo between Beeston and Biggleswade on the A1 southbound is now rotated on occasions to take a rear view. White, 'Gatso lines', have appeared on the road surface beyond the camera. Could this be one of these dual function cameras the were the subject of my original post Quote

Could this be one of these dual function cameras the were the subject of my original post I've seen a truvelo visibly flash as I approched it and it definately wasn't UV. Saying that I never received a fine so it may have been a dummy camera although from what I have seen in the past they use a magenta filter over the flash to stop it blinding people. There is sme good info here www.pepipoo.com I also find it incredible that it's OK for it to flash in your face... after all it's illegal to keep you high beams on in the face of oncoming traffic. On balance though I am happy with speed cameras. Because all the money has been put into them at the expense of traffic police numbers I can speed practically without worry as long as I keep my eyes out for a large bright yellow box by the road side (not exactly difficult). Gone are the days when you had to keep your eyes out for roadside checks. Also I think cameras catch just the type of people who deserve to be caught - the type who drive along in their own little world paying absolutely no attention to what is going on around them. Quote
Blatman Posted April 21, 2006 Posted April 21, 2006 I've seen a truvelo visibly flash as I approched it and it definately wasn't UV. And it never will be. Truvelos are IR, not UV. Quote

Blatman Posted April 21, 2006 Posted April 21, 2006 I misinterpreted what you were saying WRT UV light. A bit of a Friday afternoon wibble on my part. I incorrectly read it as a suggestion that Truvelo's use UV light for the "flash", which you clearly didn't mean at all. Is it home time yet? Quote
