That an installation and finding of the right angle for a laser interception isn’t easy, knew even the CIA in 1960, when its agents targeted the Russian embassy. In the article about bug jammers you can find out more about the possible protection from laser interception. Those that use cellular 4G LTE tracking can handle long range connections if your kids visit somewhere out of. Reflected beam can catch undesired sounds (buzz, noise)Ī professional laser interceptive device can look something like this: Professional laser interception Range: Not all GPS devices are created equal.Of course, the reality is much more complicated, and we need to work with occurring problems. Professional long-distance listening device The attacker is therefore only going to need a few primitive components (see above) to construct a device that will enable him/her to reconstruct conversations happening in buildings dozens of meters away. Devices for long distance listeningĪ device for long distance listening can be constructed even by an amateur, using only a few trivial components. It may sound difficult, but even on YouTube can be found easy demonstrations of this process in ideal conditions, even with devices for a few bucks. Afterwards it is possible to reconstruct the original sound waves. ![]() ![]() Laser interception uses simple physical laws – laser beam reflected from the glass panel of a closed window transmits vibrations of sounds in the room. However, they can be “visible” to a laser beam. When this wave hits window glass, it creates very small vibrations that are invisible to the human eye. When people talk, they create sound waves that spread in the air around them. ![]() How do long distance listening devices work
