Question about truvelo type cameras...
Discussion
A few of these cameras have popped up near me. Not sure if they're actually made by Truvelo but they work on a similar idea, sensors embedded in the road a few metres ahead of the camera measure speed.
The cameras are set up to work in one direction, and the sensors only cover half of the road surface - the lane heading in the opposite direction is sensor free. Most of the cameras are on straight sections of road with almost 1km visibility. So I was wondering, should somebody be travelling too quickly would pulling out in an overtaking style and passing the camera in the opposite side of the road still set it off? I've seen a couple of folks do just this and it's made me curious

aid, then you get away with it... great huh? the best way to avoid a nicking is to drive (possibly) dangerously. 
Interesting fact you may not have known.
As well as making scameras Truvelo also make guns www.army-technology.com/contractors/machine_guns/truvelo/index.html - Sniper rifles to be precise.
Wouldn't it be very apt then if people take revenge on the cameras with guns made by the same company

Interesting! I had thought that 1) if the sensors cover only half of the road they couldn't possibly detect speed on the other side accurately 2) they must have some sort of function to check which "direction" you're travelling in anyway...
One of the cameras has been placed just inside a speed limit change from 100km/h to 80km/h. But when the camera was put there they moved the speed limit sign on the opposite carriageway about 500m further down the road. So for 500m the speed limit heading east is 80km/h and heading west it's 100km/h. Again this suggests to me that the sensors don't cover the whole road.
And one more observation which came to me after cycling over the sensors at the weekend - surely instead of attacking the cameras the easiest way to disable one of these would be to take a pick axe and sever the sensor connections? A bit more stealthy too... not that I condone that sort of thing

A bit more stealthy too... not that I condone that sort of thing Its called a 4 inch nail Zax, and its hammered nicely into the top of the loop so cutting the connections. Some of the older designs used pneumatics, basically an empty air filled tube protruding slightly above the surface with a pressure transducer to pick up the pressure pulses of cars going over.
All too easy allegedly...

Surely that will just result in 2 weeks of roadworks while they install a new sensor and resurface the road. This will just result in more traffic delays which will stop you from speeding, and also increased council tax bill, as it's you and me that have to pay for any work done.

...we are going to pay for it whether it gets damaged or not so why not make it how WE want it - TOTALLY F
KED!

The Truvelo SR .50 is a specialised anti-material rifle with outstanding quality and accuracy. Targets identified for this rifle are heavy armaments with sophisticated electronic guiding and sighting equipment.
Bet that would make a Nice big hole in the side of one
sounds like they actualy designed it for the job
