I think there's a misconception here: most security setups aren't like in the movies where there's a guy sitting in a room with 20 screens, watching all the security camera feeds intently for something out of the ordinary. Yes, in high-security facilities, that's probably the case, but for the vast majority of security cameras, no one is monitoring them in real-time. They're just there so that when something does happen, someone can go look at the recorded footage to see if there are any clues or evidence.

The "camera-shy hoodie" defeats this latter type of security camera setup. Perhaps the article should explicitly say that this hoodie will be counter-productive in a high-security facility, as you'll be immediately noticeable to someone watching those cameras in real-time. But most cameras in the real world will not be monitored in real-time.

This is an art project. The point has never been to defeat any security system or facility.
