Unlimited GSM transmitter

Multi-function device that can be used either for  environments or vehicles.

Call the transmitter from any phone or cell phone, from anywhere in the world and listen to the environment sounds.  Its microphonic sensitivity allows you to hear sounds and voice far up to 10 meters. As opposed to other surveillance listening systems, the range of this system is unlimited. Indeed, it is possible to listen to conversations wherever the GSM mobile cover exists, either in Italy or abroad.

Infinity-GSM is a surveillance transmitter that utilizes the GSM base station for data transmission. It is sufficient to compose the telephone number of the inserted card to activate the environmental transmission.

The SIM-card mini-reader is accessible, so that the SIM-card can be changed. It is possible to effectuate recordings by connecting the appropriate optional lead to the earpiece outlet of your telephone or mobile phone and the other end to any recorder equipped with an external microphone inlet.
