How would you make an as yet legal giant portable zapper capable of causing spark or induction induced trauma to digital fixed speed cameras,or maybee hand held ones for in your face journalist cameras. How much light would it take to damage a ccd ??? (the british would love such a machine they have been smashing speed cameras in acts of civil disobedience)
One way to foil a flash camera is to synchronise a flash aimed at the lens with the camera's flash aimed at the target.
It is well known that if a xenon tube is energised to just under its spontaneous breakdown voltage, it can be excited to breakdown by the flash from another tube being fired nearby.
Unfortunately, the gatso speed cameras fire 2 pictures so the progress of the vehicle in the calibrated time delay between flashes can be measured against markings on the road. This creates the extra complexity of a second critically biased xenon tube that must be prevented from discharging at the first flash!
Theoretically, they need both pictures to prosecute - otherwise they have no proof of speeding, but one picture means they have your number plate and can prosecute for illegal attempt to defraud speed enforcement!
PS
The most common attack on gatso cameras seems to be "necklassing" - where a scrap tyre is hung over the camera box and petrol poured in it and set alight, although I have seen news footage of the occasional gatso blown apart with explosives.
Apparently the innards of these camera boxes cost some ridiculous amount of money - something in the region of £40k - 60k so these attacks really hit the money grabbing bastards in the pocket, as well as the loss of fines!!!

In Holland they drill a hole and insert tube of expanding foam.
Kickboxing is very effective and often undetectable and thus unprovable in court. After several months of many destroyed knees, the in-your-face photo journalists will back off. Pain and suffering are greater motivators/demotivators.
