SubscribeThe sophisticated technology of the TFT colour display for the video function of the door communication system has become a much-sought-after item from Gira.
Since "video" still has great potential for market growth in Germany, Gira has expanded its repertoire in this field again with a large 5.7" VGA colour display in the design of the Gira SmartTerminal. The display of the Gira VideoTerminal presented at the Light & Building has a resolution of 640 x 480 pixels. The picture quality remains high even when viewed at an angle.
Communication occurs via the practical hands-free function, which guarantees maximum clarity thanks to voice-controlled talk-back with echo and background noise suppression.
Call acceptance, start-up and modifications to the menu occur via a backlit knob, which is turned and pressed. This kind of intuitive operation is already standard in automobiles, for example. The knob flashes for an incoming call; if it is pressed, it stops flashing and illuminates green. The call is accepted.
The knob 
also allows certain parameters in the menu to be changed in an uncomplicated way. For example, the landlord can set the brightness, contrast, colour intensity and call tone melody and volume or set the switch-on time of the colour display.
In addition, four buttons situated below the display have been assigned permanent menu functions: switch call tone on and off, switch light, open door and call up menu levels. Different cameras can also be selected here, if available.
The Gira VideoTerminal is a technically fully-equipped Gira video hands-free feature home station with an added dimension. It can be installed either flush- or surface-mounted; surface-mounted installation is particularly suitable for upgrading existing buildings.
It can also be installed in the Gira modular function profile. The glass surface framing the screen is available in design variants black, white and mint. They harmonise visually with frames made of black, white and mint-colour glass from the Gira Esprit switch series.
All of the components, e.g. switches, socket outlets and the Gira VideoTerminal, can be installed with a completely uniform appearance within this design line.
Signal transmission of the audio and video data with the Gira VideoTerminal occurs via the reverse-polarity-protected and short-circuit-proof Gira 2-wire bus. Two additional leads are used for supplying the device with power. The Gira VideoTerminal will be available starting in February 2007.
