Classic "Radio-based Bugging Devices"
Are mini transmitters still up-to-date as bugging devices?
The wireless classic bug that transmits all conversations, a perennial favorite!
Classic radio mini transmitters continue to enjoy high popularity. Even though they have been somewhat displaced by GSM bugging devices. However, there is no other bugging device that could undercut the minimal dimensions of a radio bug. The most modern bugging devices of this type are no larger than the clip of a 9-V battery. For bugs used to listen to phones, these devices have even shrunk to pea size. So if it is necessary to use a particularly small mini spy and the range does not exceed one kilometer, you are on the safe side. In the further articles, we present particularly powerful bugging devices of this type. Small, easy to camouflage and hide!
The wireless bug, the classic bugging device. What is required, what distinguishes it? What must these bugging devices be able to do?
- Minimal dimensions
- Unobtrusive to hide
- Good audio qualities
- Long operating times
Bugging devices or listening devices are intended to provide acoustic information, meaning you want to hear everything spoken in a room. Classic mini transmitters are still used for this purpose, i.e., radio transmitters in mini format. Really good radio-based listening devices are not only extremely small, fitting on a fingernail because they are equipped with nano-semiconductors, but they are also completely frequency stable. Even with decreasing battery voltage, they remain fixed on the initially set transmission frequency. Otherwise, stable reception with a radio scanner is not possible. The audio spectrum is digitized in good transmitters, leading to excellent voice transmission. Equally important is the modulation of the transmitter. In serious listening transmitters, this is in the narrowband range, technically termed NFM, and operates in the 5kHz range. Broadly modulated transmitters are completely amateurish and unprofessional and belong to the past. However, this is something completely unknown to many providers because there is no technical knowledge available. Only a few providers can offer the very demanding criteria for such electronic surveillance technology that truly meets today's requirements.
