A  2-way 13amp adaptor into which we have fitted a powerful GSM transmitter to allow you to listen into the room from anywhere in the world.

Simply fit a SIM card into the adaptor, in the slot provided, and you can phone into the adaptor and the internal microphone will be opened, totally silently, allowing you  to hear what is happening in the room where the adaptor is fitted. 

This is a Dual Band unit which is totally covert and as effective a listening device as any on the market. Powered from the mains so there are no batteries to replace, please note that this unit cannot actually have other items plugged into it.
