This fully functioning double mains adaptor is fitted with the very latest GSM listening technology.  Simply plug it into any mains socket and one can then monitor all conversations in the room from anywhere in the world.

By calling the supplied number the unit will silently switch on, enabling one to listen to sound up to 30 feet from where the device is placed.  Sound is filtered and 100% buzz free for perfect audio clarity.  The device uses power from the mains, so is perfect for long-term monitoring applications.  It also has an in-built battery back-up in cases of power failure.

The GSM Adaptor will work when connected to any 3-pin UK type socket with 220/250V and where a 900/1800MHz mobile phone network is available.  Other adaptors can be supplied for use in any country worldwide.
