A couple of months ago, I saw someone pushing a visor that would reflect any attempts at photographing you, blanking out your eyes and partially obscuring your face in response to a camera flash. It wasn’t any particularly new technology; it appeared to use the kind of plastic that some people use (illegally) to obscure license plates from toll barrier cameras.
Then I saw this: a barely wearable gadget that claims to detect infrared signals from surveillance cameras. When it thinks you’re being watched, the “surveillance spaulder” gives you a little zap. If you’re wearing something like this, you’ll want to stay out of areas like Central London or most of downtown Manhattan in New York City, unless you like small electric shocks.

The spaulder won’t protect you against surveillance, it will only alert you when it’s happening, and ensure that the pole cameras will always get photos of you twitching. I’d like to see more about the plastic, though — sounds like the new aluminum foil.
