[W126 Coupe] Photo Blocker

[Shayegan, Richard]

CCD's are sensitive to infrared...which is why they put aggressive IR
filters on them. Even Canon's 20Da which is marketed as an astronomy
digital camera has a fairly strong IR filter. While I think that and
photo based ticket should not be valid on the grounds that by itself the
photo radar/red-light shouldn't be considered admissible evidence (they
seem to go wrong too often, plus they are often issued to the incorrect
person, and while this is easily cleared up by a person who has time to
go down to the adjudicator's office, this opens the elderly, the
uneducated, and the busy, to potential abuses by the government), I
don't care to block red light cameras because people shouldn't be
running red lights. The photo radar on the other than is easily picked
up by a valentine one so no need for the photo blocker. I on the other
hand am reducing reflectivity to hinder laser gun range. I've got pick
ups on my V1 where I was grossly overly the speed limit, so apparently
it can work well enough to give me warning before a lock (though not
enough to be really trustworthy, I should get a laser jammer).

I was actually thinking about that...since most digital cameras (CCDs at
least) are sensitive to infrared, how about putting extremely high
intensity infrared lights around the license plate frame, but always on,
to avoid having to sense when the pictures are being taken (if being
taken by radar cam with digital.

 

Anyway, I guess the more reasonable response is to just drive the speed
limit right?  ;)

I designed my system about 6 years ago, we no longer have photo radar in
Ontario. Ahh ain't technology great. But I bet it still will work if you
fire the flash into any lens at several thousand joules it will still
burn out the image, maybe. Or fire it at your licence plate??

    Luckily I don't have that problem anymore.

	A lot of the cameras no longer use a flash, and use digital
controls to level the light.  Some cams (particularly red light cameras)
have multiple cameras in different locations.

	When they brought in, temporarily, photo radar in Ontario, I
designed a system that beats it 100%.

	I installed 3 small Zenon flash strobes where the licence plate
screws go, and a slave to fire them in the fourth spot. When the flash
from the camera fired, it hit the slave and fired my 3 strobes back into
the camera. It burns the picture out completely as it highly over
exposes the film.  I used high speed capacitors so recovery was in a
millisecond, as the photo radar usually takes 2 pictures. I got some
photos from people who had been nailed and worked out the correct angle
to mount the strobes. To test, take your camera and take a flash picture
into a mirror.

	
Have fun,

	
Iain

		Photoblocker doesn't really work...sometimes. Yes it
does successfully white-out the photo, but there are ways to bring back
the information, so they might still get you. The plate covers are more
reliable but then again they are illegal in many states. A good place to
buy this sort of stuff at is www.radarbusters.com and a good place to
discuss the products with some people who know is
http://www.radardetector.net/ though it doesn't seem to be working right
now.

		Hi Ronny,
		
		I've not had experience with these products either,
though the website has a lot of info., testimonials, etc.
		
		Here is the site
http://www.phantomplate.com/photoblocker.html for more info.
