Farfisa is among the leading international players to introduce intercom technology in homes worldwide: our industrial history is marked by a series of products that have defined the relations, forms and customs through which communication has evolved year-after-year, shaping our daily habits. Each item, material and construction detail, every mechanical solution and technology enclosed in our intercoms have gradually brought the world closer to our daily lives, enhancing the comfort and security of private, professional and commercial spaces. In 1967, as a division of the legendary "Farfisa Strumenti Musicali" brand, we were among the first companies to envision, manufacture and diffuse intercom systems in Italy and overseas. In 1993 we became an independent division with our own name. To tackle and win the globalisation challenge, we devoted greater emphasis on understanding customer needs and on product quality, aided by a solid industrial tradition and the precious gem of authentic Italian craftsmanship. Problem solving and customization are our points of strenght: carefully listening to the customer, we analize and plan a solution, sometimes really "tailor-made" for that specific installation, that can mean a change in the product or even the entire system configuration.
