Professional listening devices, also known as hidden microphones or “bugs,” are small microphones capable of being hidden from plain sight while still being able to pick up conversations. These hidden listening devices are often employed by law enforcement, spies or private investigators for the purpose of catching people engaging in illegal or incriminating behavior. Installing professional listening devices requires clever use of objects to mask the microphone, as well as the equipment that is used to pick up the audio signal. Warnings Writer Bio
