The ECGO-G is a telephone entry system, installed at the entrance of a building or outside gate area. It is an ideal product replacing the traditional door/gate phone. It allows you to speak with visitors standing at the entrance of your company or house entrance from a remote location. A visitor, by simply pressing the Call button establishes a mobile call with you. During the call you will be able to activate two devices, whether it is gate or activating / de-activating any other devices by pressing appropriate digits.
