This extension lead has a powerful GSM bug fitted inside. The extension lead looks normal in every way and importantly all 8 sockets work as not to arouse suspicion.
The microphone is super sensitive and will hear sounds clearly up to about 15 metre radius.
Any time you need to listen just dial the number of the sim and within few seconds you can listen. In addition the user can send text message to the unit and adjust microphone sensitivity, low, medium, and high.
The other advantage is you can set to voice command mode so when it hears a sound for about 10 seconds, it will send you a text message and immediately call your number. When you answer your phone, you can then decide to carry on listening or end the call. You can also configure by simple SMS command and add up to 3 recipients who will be alerted if there is any sounds thanks to the voice command feature.
The sound quality is excellent and clear. The device operates on GSM 900/1800/1900 Mhz for worldwide coverage. Supplied complete with PAYG sim already fitted so ready to go. Needs no batteries as the GSM device is mains powered.
