Miniature spy microphone
A miniature spy microphone is a eavesdropping device that stands out for its very small size. Indeed, it is about the size of a phalanx, even going up to a coin and weighs no heavier than a few grams. In addition, miniature microphones are labeled "professional microphones."
functioning
In terms of operation, the miniature micro spy doesn't differ much from an ordinary spy microphone. In reality, it is the same since size is the only diverging element. In a nutshell, the microphone picks up the sound, records it and sends it to an operating platform. In this version, it is possible to set up the recording schedule ranges for example.
The other feature of these microphones is however quite simple. A miniature spy microphone has a SIM card. Once the card is installed at the designated location, the user only has to call the card number to hear the conversations picked up by the microphone in a certain spatial setting. In short, the GSM network is used. In fact, in areas without network coverage, the microphone cannot be called.
use
The miniature spy microphone is also useful when betting on sensitive listening where extreme discretion is required. Some professionals working in the information trades use it: police investigators, journalists and private investigators.
