Speed camera confusion please help

[z3ster]

I was travelling along a 50mph stretch of dual carriageway this afternoon that I had not been along for a while.

Suddenly came around a bend and was faced with a front facing speed cameram, Truvelo?, I believe.

I jumped on the brakes, as you do but don't know whether I was caught. What was strange was that there where lines on the road after the camera as you get with a gatso. There was also a series of maybe 2 or 3 very narrow lines before the camera. Never seen this before.

I was below 50mph before I hit the first white lines and obviously well below 45mph by the time I hit the lines after the camera.

My questions are:-

1)Do truvelos flash if they get you?

2)If not at what point are they likely to get you? before you get to the first lot of lines or as you get to them?

3)What are the lines after the camera for?

Any help would be useful as up to now I have a clean licence and hopefully still have one.

Thanks.

if it had the 3 lines before the cam, thats a truvelo cam.

the lines are the distance/speed tell tales.

as for the lines after the camera, they were probably from a previous automated traffic officer.
sneaky scamera scum probably left them there to make you think you still had time to brake when infact you were already in the trap.

iirc truvelo have an infrared illuminator and dont give a visable flash. as their forward facing a bright flash head on could cause an acciedent.....and the scamera scum wouldn't want that.

edit for a typo

Most Truvelo's have an infra-red flash that you can't see. However, some of them have a standard flash which is behind a magenta window so that it doesn't blind the driver. I have seen the one on the A505 in Luton flash when a Mercedes driver decided that the 40mph limit just wasn't for him.

Truvelo's take one picture only, and the lines after the camera are so that they can turn it around and target traffic from the opposite direction.

Yes

There is a sensor before the three lines in front of the camera (about 6 ft) the picture is taken as your tyres hit the three lines. The picture is used for identification and to determine which vehicle in a multi lane situation

The latest one has an option of taken a secondary picture based on a configurable fix time after the first photo - primarly to identify motorbikes.

See the link above for all the detail

Thanks for the replies and the link.

I see how they work now.

Hopefully then I was below 50mph at about 6.5ft before the white lines.

Cheers
