When a group of dangerous criminals, or a mafia “cupola”, meets in secret to make decisions on their illegal business, they usually take a number of precautions to ensure that the police cannot catch them.
In such situations, any operation of wiretapping of phone lines or planting of bugs is almost impossible, unless the lives of agents are put in grave danger, also risking the failure of the entire chase.
How Laser Microphones can be helpful for Police?
Therefore, to gather intelligence, the police may use laser microphones, tool to listen to conversations from a distance, in order to gather the information in the safest possible way. For example, this is the case with laser microphones, which give their users the opportunity to capture the conversations that take place inside a closed room, thanks to the use of a laser beam.
The laser, appropriately pointed at the window glass, in fact, is able to read the small vibrations of the glass caused by sounds, noises and voices inside the room. By pointing the beam on the glass at the correct angle, and retrieving the reflected beam with a receiver, you can read these vibrations, and turn them into sound and voice, enabling you to successfully carry out a remote listening operation without running any risk.
In fact, the laser microphones are able to secretly pick up conversations at a maximum distance of approximately a mile, allowing the monitoring agents to work without excessive stress, and to quickly take shelter in case something goes wrong.
Not only for law enforcement, but also for private detectives who are following a case of industrial espionage or marital infidelity, the laser microphones can prove very useful; if you wish to learn more about them, you can visit the Endoacustica website.
