Here is the link to a really good photo radar blocker.

I've had the spray on kind of blocker for two years and have not gotten a ticket by mail since. But this product is better.

It acts as a normal plate light until it detects the radar signature used by photo radar (boxes, vans, anything) and when it sees that, it goes into high intensity mode until the radar signature goes away. This is an LED light, so it is quick to switch to high intensity.

Eventually I will get one, probably when I get a Cheetah M27 Rider (Blinder) jammer system.

SCDM Photo Radar Blocker

I believe you, but... how do you know it's any good? Friends have one?, testimonials from verified users?

I am not rubbing salt with you, I'm just curious about what let you to believe in it's properties.

Not much info on this.For the $$$ I'd like to know it definitely works?

Someone is going to have to have one that one of us knows before we will accept it as proven.

But the theory is sound. We know the radar trigger part works, its the same as a radar detector. The question is does the LED really overload the camera?

Anyone that has done real photography (cell phone doesn't count) knows that you set the aperture and shutter speed based on the amount of light on the subject and background. Changing one or the other changes what shows up on the negative.

Most photo radar strobes a millisecond before snapping a picture, to cut through any shadows that might exist, say from being a cloudy day.

So if this system sends a strong pulse of white light from the LED array, backwards, and it is too much for the aperture setting of the photo radar (we know the shutter speed is pretty high, or moving cars would be blurry) then what is on the negative is a bright white blotch in a circular pattern.

This is how photography works, the fact it goes directly into digital form doesn't mean the physics of light transmission have changed.

I think it will work, but for $9 you can buy a can of PhotoBlocker like I did, which I know works because I don't get tickets in the mail for blowing past photo radar boxes anymore.

EDIT: on the other hand, I'm sure the city police have a picture of the back of my bike with big white splotch over the plate where the PhotoBlocker reflected the strobe back into the camera lens and overloaded it, and although it is not a priority, someday they might figure out who it is.
