The GSM tap detector has been created to protect your conversations in case your GSM phone has been modified or changed. It has been designed to act as an attractive desktop stand.

Its features include a built-in radio-frequency detector, a controlling scheme and a noise generator which activates when the phone is active. Therefore, the phone should be kept in the gsm tap detector to provide 24 hour indoor protection. Normal calls can be answered in the usual way since you will hear the telephone's melody or vibration and simply remove it from the stand. 

Hidden 'spy' activations do not produce any sound or vibration and this is where the GSM detector will protect you. In the event of a 'spy' activation the GSM tap detector will automatically turn on its noise generator and the listener will hear this sound only. You will also instantly notice your phone's activation thanks to the built-in LED indicator and the low sound coming from it.
