What is sound supervision?
Sound supervision is an act of listening to third -party conversations and their recording. This technique often uses the enforcement of law, private detectives and government spy agencies. Most sound supervision consists of a room buging, wire, knocking on the phone or distance. Each provides clear advantages and disadvantages depending on the situation.
The session is one of the most common and simplest forms of sound supervision. This is preferred because it is highly inconspicuous and allows you to clearly record two sides of the conversation. Small sound devices, commonly called errors, are connected to the internal perimeter of the phone to pick up the conversation. The signal is wirelessly transmitted to another device that records the conversation. The disadvantage of this method is to access the phone that will eavesdrop it properly.
The microphone room is another sound supervision technique that is often used. This includes planting a wireless microphone in the room for the bezedthe conversations of conversations. There are masked microphone rooms to look like pens, clocks, stuffed animals and many other hidden forms. This microphone sends the signal to the receiver as well as the wiretap, and the signal can be directly recorded. The disadvantage is access to some rooms and obtaining only one side of the telephone conversation if it takes place in this room.
Hidden transmitters known as cable wires are known devices that were presented in many television shows and movies. A small microphone and a broadcasting device are worn under the clothes of the person to send the signal back to the receiver and record the conversation. This allows the person to wear the wire to ask questions and get specific details that simply listening to other people's interviews could not provide. The disadvantage of this method of weaving access to the person to be recorded, and also to hide the microphone in a way thatIt hides but allows clear recording.
long distance microphones are another hidden means of sound supervision. The parabolic microphone, often called a shotgun microphone due to its long shape, has a strong ability to pick up conversations up to 300 feet (91.4 m) from here. Its main disadvantage is its high sensitivity. It can pick up other sounds and cannot work if obstacles such as trees and cars are between microphone and conversation.
