I sometimes wonder how well super-reflective material could mess with them. I know a lot of reflective stuff tends not to photograph well because cameras automatically adjust to the amount of light they throw out and that darkens everything else, but I don't know how much it would take to actually consistently blind them.

If it has night vision with an infrared emitter, a retroreflective vest will dazzle the hell out of it. It won't do anything for daylight or passive IR.

A laser pointer can also dazzle a camera. Since most cameras attempt to adjust for brightness, the super bright laser beam will cause the rest of the image to become extremely dark.

When I worked for a company that made video surveillance equipment, I toyed with the idea of embedding IR LEDs into a hat. Most cameras detect IR the same as visible light, and if you can produce enough IR, it might mask your face.
