Traffic cams cant/dont use IR. Most have a regular speed flash and standard or low lux, highspeed photo camera.

IR cameras have an especially hard time with license plates because in the US plates have a reflective coating that VERY EFFICIENTLY reflects light, and in the case of IR light if you look at a license plate with an IR camera, you see a big white block.

SO this wont help you avoid that traffic ticket. The effects of this exploit are really most effective on IR sensitive surveillance cameras. While some other cameras have some IR sensitivity, they arent nearly as sensitive as cameras designed to see in the IR spectrum like IR surveillance cams.

Also, having IR illuminators all over your stuff may well make you stand out in other ways, say if a police officer has a nightvision unit in his vehicle. So I'd suggest avoiding that unless you want to call attention to yourself.

I'm a technician for a company that distributes surveillance cameras and related equipment, and I can state for fact the following:

1) This WILL work against IR cameras or standard cameras equipped with appropriate filters to allow them to see IR.

CAVEAT: In most cases, such cameras do not become IR sensitive until natural light levels drop below a certain threshold (LUX level). Once the natural/ambient light reaches the critical threshold (say .01 LUX ) the IR illuminators, IR sensitivity mode/filter kick in, and it starts to see it. Otherwise, most cant see IR, such as during the day.

2) Non-IR cameras, and those not equipped with appropriate filters, will not see or react negatively to this type of "attack". We have a ton of demo cameras hanging in our shop, and non-IR cams have IR cams with built in illuminators pointing directly at them from the other side of the room, and do not show any effect (positive or negative) from the rather intense IR light being directed at them.

Further, if this is something you want to do, you can pick up the necessary components from places like Radio Shack or order from Jamecofor pretty cheap and make your own magic camera death-ray. Don't waste your time/cash on this thing.
