Interphones play a key role in defining the ambient appearance of interiors. The aesthetic appeal that they exude also defines how the architecture is perceived by a beholder. The Deluxe Bus Video Panel BVPC 850 impresses with a highly consistent overall concept. Communication via this indoor interphone centres around a generously designed video panel with a screen diagonal of 18 cm. Its well structured user surface offers alternative possibilities in terms of comfortable and intuitive operation. Large mechanical keys serve for operating primary functions such as taking calls and opening doors. Additional functions and the user interface are operated via a touchscreen. The video indoor call station BVPC 850 features a casing made of black or white plastic and can be optionally customised with front and rear panels in various colours and materials in order to seamlessly blend into different architectural interiors. The device can be mounted over plaster or standing upright via an installation bracket. With its clear language of form and sensitive user guidance it conveys a high degree of elegance.
