Modular 2-Wire Bus System

The **ATIS modular system with a non-polarised 2-wire bus** provides a flexible solution that can be adapted to the needs of each resident. Each apartment can choose between an **audio handset** and a **video monitor**, available in two screen sizes and with optional **Wi-Fi connectivity for control through the mobile app**.

All of this can be achieved **without replacing the existing wiring**. To add a video monitor, simply install the compact **NV21 video distributor**, designed to fit easily inside the existing back box. In many installations, this distributor may not even be required.
