- Are you free to use UTP? Go with MEET , FERMAX's 100% IP platform. Power your devices with PoE, install standard switches, and scale up to 10,000 homes.
- Does the user need mobile calls without community Wi-Fi? Add the Connect 4G module to any DUOX PLUS panel and forward calls to the DuoxMe app without opening ports or relying on the community router.
- Check here which cable FERMAX recommends.
