How To: Make An Invisible License Plate
Here is another take on using IR lights to blind a camera, this time a photo-radar camera no-less. I’m not really sure on how well this would work for you, and it’s probably highly illegal, but if you want to try it for your own educational purposes go ahead.
All you really need are some LED flashers, some IR lights, and a bit of soldering skill. If you put this together and it actually does blind a camera, remember that it doesn’t blind the naked eye and might arouse some suspicion from any law enforcement agency.
