interesting. i always thought that IR LEDs wouldn't be bright enough, guess they are (at least in total darkness)! as mentioned all over in the thread, adding jitter would probably help. worth noting that every camera is going to have a different AE algo, so it could not be relied on and you only need one frame to succeed for the system to be defeated. what you would definitely get, however, is excessive triggering of any region of interest detection for the video stream. not exactly low key! all told, pretty cool experiment nonetheless! on a related note, i often used to think it would be cool to put IR LEDs in public places where people take pictures, sort of like hidden messages or art for people to discover, but only after they look through their phone cameras.
