Professional quad-band GSM audio transmitter equipped with two amplified stereo microphones. The tiniest audio bug on the market!

This amazing miniaturized GSM quad-band audio bug is perfect for remote audio surveillance within rooms and vehicles. Equipped with two microphones for a wondrous audio reception, the decice measures only 39 x 40 x 9 mm and can be also be concealed in electrical outlets, switchboards, junction boxes or small household appliances.

The transmitting audio is developed by a powerful DSP (digital signal processor) that reduces and eliminates noises and rustles whether in domestic or vehicular environment. The firmware allows the complete real time management of sound.


Positioning and size

The GSM-002 is particularly suitable for being installed on any kind of vehicles, from the oldest to the latest ones on the market. Thanks to its strong rejection to electrical noise and 50 Hz AC voltage noise residue, it can be placed on electrical switch panel as well as domestic power plug. Not for anything else, it is considered the smallest transmitter of its kind in the world!


Audio features

Now available 2 knowles microphones that can be selected individually or coupled with a "pseudo stereo" function that activates them both. It is possible to set up 2 programming thresholds of internal DSP to reduce noise in the cabin, for moving and stopping vehicles. Another special functionality we call “Dynamic Mik” enables on board and external microphones to be switched automatically when the vehicle is stationary. You can have 3 programmable levels of sensitivity: recall on moving towards the base station with self-breakdown function, recall on VOX function and threshold setting at various levels.

Remote functions

Virtual lock that reduces accidental or non authorized reprogramming.

Single listing functionality, eliminates non authorized user on listing the unit.

“Ring Alarm” function towards base station with voice call and succeeding self-breakdown by module.

Diagnostic LED remotely switchable OFF through SMS.


To improve GSM bug performance it is possible to connect it to the GSM recorder which allows you to record everything happening in the monitored place. Thanks to this innovative system, you can listen to audio recordings many times as you want, remaining comfortably seated in front of your PC.
