Agreed, this will only work on black and white cameras designed to work at night with IR illumination. They have to be sensitive to IR to see in the dark but the chip is only expecting a small amount as it is normally reflected. A direct IR led beam causes a flare which blanks the face.

Standard daylight cameras have a filter build on top of the lens that blocks IR-light.

Possibly it would work with nightvision cameras.

Even stuff like this that wouldn't fool a human may be enough to mess up license plate readers and facial recognition software. That software is really what makes the cameras evil. Go to wikipedia and look up "ANPR". The computers connected to the cameras build up a text database of plate numbers, locations, and times that allows them to reconstruct an exact pattern of your movement. The UK has it the worst, but it is coming to the USA too. Once it gets good logging faces we're really screwed.

The best bet is probably laser diode busbars, much higher power and can be focused or defocused with appropriate optics. Of course it would need a heat sink and beefy power supply, making it more suited to installation next to a license plate.

What was the highest wattage that ya'll tried? From the video, it looked like ya'll only used the cheap ones, like the ones found at RadioShack...

If it doesn't need a heat-sink, it definitely wont do anything...

like. BUT in the beginning, you should not test with other lighting in the background, and why is it reddish tinted? just curious.

I was thinking more of blocking red light an toll plaza camerras using IR all around the tag...Just to aggervate them....lol.....50cents my ass bitch.

am i missing something. The red filter over the lens?

Nice to see this doesn't work before I go waste my time with this strategy.

only works at night when camera with night vision are enabled and night vision is on, you then use a Infrared Light

I have the same swann quad.

In all the demonstrations online where this DID work, I felt like the resolution of the cameras was so poor that making out facial features would not have been possible anyway. Hence: all it did was make you stand out like a candle in a dark room.
