Sadly there is no supremely high-tech activity at work in this patent like sending out a flash and scanning for feedback from lenses, instead it is basically an automated anti-glasshole ready to punch anyone who is idly passing by with a recording device, but will completely miss the person with a hidden camera recording them for some time from arms length.
Yea, seems an expensive and obtuse solution for a problem $10 worth of wire and high-intensity IR LEDs can fix.
That reminds me, pick up an IR filter element for my hipster coat button cam...
Which, in turn, reminds me to ask - do we know if Glass has an IR filter built into it? IF so, then my high-powered IR LED system won't be very effective against them (although, it will still be highly effective against traditional security cameras).
Hmmm.... maybe some sort of pocket-sized EMF pump?
I can't imagine any issues with carrying something like that in close proximity to your genitals...
Side note, RE: EMF pumps - I love how a Google search of that term brings up nothing but "ghost" sucker, er, I mean hunter, equipment sales sites. Nothing funnier to me than droves of people doing their damnedest to prove P.T. Barnum right.
Outdoor photos (and even some indoor ones) tend to look like complete trash if a camera has no IR filter, so I would venture a guess that it does indeed have a decent IR filter in place.
