This fully functioning 4 gang mains extension lead with a hidden listening device bug allowing you to listen to what’s happening in the room where it’s deployed, with the added facility to record audio onto your Micro SD card up to 16gb for future playback. Both functions can be operated by sending a text to the device to turn on and off. It’s like having a listening device and a voice recorder in a small box. We test & setup the device ready, so all you must do is plug it into the mains, easily fit your own sim card to listen, anytime, anywhere in the world. It really is that simple. We can fit a GSM sim card ready for use, when sim card is purchased in our store, or you can use your own GSM sim card, contract or pay as you go.

When you call the mobile number, the device will auto answer to allow you to listen to the surrounding noise. Or just send a text to record audio to the micro SD memory card you have inserted in the device. Therefore, you can either call up device to listen or record audio to the Micro SD card installed (card not included).   

Devices are hand made to order in the UK exclusively for our customers. Unlike cheaper imports, all our products are strategically assembled to enable the microphones to pickup activity, more effectively. Beware of cheap Chinese copies..

The listening device auto-call back function (sound activation) can also alert you by calling you whenever it picks up sounds in the area. This saves you time as you don’t have to listen in unnecessarily. You can easily switch this function on or off, just by sending a SMS text to the device. This feature is great for protecting your property to monitor unwanted activity.
