I've often wondered what would happen if I wandered around with a bright IR led flashing on my lapel at about 30 or 60 Hz and sufficiently invisible to human eyes yet low wavelength enough to get into most CMOS chips and dazzle the camera.
I think this on shopping trips routinely. I don't like being surveiled and even though I have nothing to hide (I've never shoplifted in my life!) I hate the persuasive nature of it all. I don't even mind being followed by a human that much, but I do mind algorithmic analysis that is far more effective, scary, and invasive. Sadly I think the answer to this experiment would be being asked to leave or an uncomfortable chat with a policeman. Nevertheless I silently would like someone braver than me to try it. You're allowed to wear a light on your clothes -- why not make it an IR one?
- a012 2y agoI guarantee that it’ll trigger an alarm to the shop security and there’ll be officer to see you immediately.
- aetherson 2y agoYou "guarantee" that? I think it's a possibility, but very far from universal.
- tivert 2y agoMaybe not "every shop," but ones with a security guard monitoring the video who's actually doing his job, trying to "dazzle the camera" would definitely draw extra attention to you, which is probably not what you want. "Dazzle the camera" is an idea that sounds good when you fail to think about the whole system, and instead hyperfocus on one component.
- aetherson 2y agoBear in mind that lots of large, sophisticated shops have policies of not intervening when someone is blatantly shoplifting. I think you're overestimating the appetite for confrontation that many shops have. Not, again, that confrontation is impossible, just that it's not guaranteed.
