Listening Devices (BUGGING DEVICES )
If live listening is a better option our GSM transmitters will work worldwide with any telephone network. Our GSM transmitters are UK made. The microphone and GSM module which now supports 3G capability due to the impending global 2G shutdown, are powerful and reliable. The microphone will give up approx 20-25 metres in range so just place the unit in an office, home or car and simply by making a call you will be able to listen to the target conversation from anywhere in the world. We offer both battery powered and mains options as well as the option of a bespoke service.
