Yet another amazing way to monitor room conversation from absolutely anywhere in the world where there is either landline or GSM telephone coverage.

This dummy smoke detector has a super-sensitive microphone fitted that will pick up conversations from up to 10 metres away. It comes with an in built sim card and you simply dial into the number which we give you and you can hear with incredible clarity any sounds from the room. The range is absolutely unlimited.

The unit comes with built-in rechargeable batteries and a charger. The batteries will allow  4 hours of talk time and 10 days on standby.
