The design of the device enables a simple, intuitive operation, which was developed by taking the aspects for Geronto technology into account. Four buttons are assigned the basic functions of calling up the menu level, opening the door, activating and deactivating the call tone, switching the light and switching on or changing between up to three possible cameras. The large backlit button for rotating and pressing is used for navigation within the menu level, which is chosen via the menu button. At the beginning, the electrician uses this to configure the basic settings of the unit. They are, among others: language selection (German, English), frequency setting, switching LED illumination on/off and termination of the cable. The end user can change the values of brightness, colour intensity, contrast and switch-on time via the menu.

The hands-free speech function is operated using the current microprocessor technology with use of the echo suppressor. The microphone is automatically activated where the ambient noises are loudest, and as a reaction the loudspeaker on the door station is switched on. If the street noise is too high, an enforcement function nevertheless enables speaking at the home station.

The Gira VideoTerminal also features all other technological innovations from Gira door communication. These include ringing tone deactivation, parallel connection of up to three Gira VideoTerminals, five different call tone melodies and the switching of an automatic door opener when ringing the bell, which is helpful, for example, in doctor’s offices.

The Gira VideoTerminal can be installed in the respective surface-mounted and flush-mounted mounting frames and integrated into the modular function profile. Due to the large display, an additional power supply of 24 VDC, 700 mA is necessary. The connection is made via the common Gira 2-wire bus.
