Around 20 years ago, I read an article about three-letter agencies in the US being able to detect computer keystrokes by monitoring residential power meters. In other words, the power company could see what people type. It seemed like a load of BS at the time, not so much now.
Just need an off-the-shelf mobile phone (60k FPS, wow!), and the ability to put a camera centimeters from your mark's device. Didn't see it mentioned, but I wonder how well this works through something like a telescope.
Interesting article! I'll be sure to return my wet paper bags to the panopticon.
One of the devices used for filming power LEDs was an IP camera positioned 16 meters away
