Software on micro USB key to easily and intuitively manage and control all the typical porter switchboard functions. In addition to the classic ViP video entry functions, the software is used to receive and forward audio/video calls and to manage alarms originating from the apartments; it has a directory of actuators, internal units and external units which, when suitably programmed, easily identify the apartment and the external unit from which the call originated. It also has a recording archive where all the calls from internal/external units (calls made, managed lost and switched) and alarms are stored. It is also possible to send messages to internal units. The software comes complete with a user license. The micro USB key must always be plugged into the computer to ensure correct operation. Minimum operating system Windows 8 32/64 bit
