The Visual Microphone: Passive Recovery of Sound from Video
(YouTube): https://www.youtube.com/watch?v=FKXOucXB4a8
Using video (even consumer video) to recover sound from silent video,
even from outside rooms. Using a laser bouncing off window glass has
long been a technique for recovering room sounds remotely. The
technology described here emphasizes the need to keep external windows
completely covered during sensitive communications! Also, we can
safely assume that intelligence agencies (at a minimum) have been
using this technique for some time.
