Multifunctional gsm triband transmitter with built-in battery
Uses the GSM Base Station for data transmission
Multifunctional independent GSM Triband transmitter usable in any environment or vehicle. You only have to dial the phone number of the card inserted inside to activate the environmental transmission. The built-in battery allows up to 6 hours listening autonomy!!
Call the transmitter from any phone or cell phone and from anywhere in the world and listen to its background sounds. Its microphonic sensitivity allows you to hear sounds and voice up to 10 meters. Recordings can also be made by connecting the appropriate "optional lead" from one end to the earpiece outlet of your phone or cell phone and on the other end to any recorder equipped with an external microphone input. Unlike all other surveillance listening systems, the range of this system is unlimited. In fact, you can listen to conversations anywhere as long as there is a GSM cellular cover, either in Italy or abroad.
