GSM 3g Audio listening bug, with a built-in rechargeable LI battery product code GSM3G1.
This small audio transmitter uses the 3g network giving excellent coverage and quality and will operate in the many countries that are shutting down the 2g network. Measuring only 53 x 37 x 23 mm is the perfect audio bug for listening into conversations from a distance.
When you dial into the bug from any location in the world you will be able to silently listen into any conversations taking place within a 10-metre radius. This is not a converted mobile phone this is a purpose-built GSM eavesdropping device built in our own workshops.
This hi-tech listening device operates on the 900MHz,1800MHz,1900MHz communications network for worldwide coverage.
The standby battery life is approximately 1 week depending on external factors such as signal strength.
For better concealment you can purchase the 600 mm extension microphone that allows the head of the microphone to be concealed rather than the whole unit. This bug also has a voice activated call back feature, enabling it to call you when sound is detected.
Suitable for all countries including those that do not have 2G GSM coverage Such as the USA
