2-Wire Video Intercom Tegui and BTicino: The Most Advanced Technology for Your Community

The 2-wire BUS SCS video intercom system from Tegui and BTicino is the most modern solution for residential installations. With only two wires, audio, video, and data are transmitted, simplifying installation and allowing system expansion without additional work.

What Does "2 Wires" Mean in a Video Intercom?

Unlike the traditional 4+N wire system (which requires a cable for each function), the 2-wire BUS SCS system multiplexes all signals through a single pair of wires. This allows:

• Faster and more economical installation
• Scalability: add monitors or handsets without changing wiring
• Compatibility with WiFi and mobile control (Classe 100X models)
• Higher image and audio quality than analog systems
