Listen to a conversation indoors from the street

And thermorectal cryptanalysis, alas, is not our method. : lol:

And sometimes I feel like applying ...

Vadim, why is it so straightforward? Anything happened ...: mrgreen:
Frankness is directly proportional to the effort made by interested parties. : lol:

One problem - a reflected beam is supplied to the device
Therefore, the beam to the glass should be strictly perpendicular: geek:
The laws of optics work here, oddly enough ...: ugeek:
