It is well suited for residential renovation and modernization projects, including occupied apartment buildings, social housing developments, and phased upgrades where minimizing installation disruption is critical.
Fermax DUOX Plus is commonly chosen when a reliable video intercom system is required without the complexity of IP networking, while still supporting centralized configuration and scalable multi-entrance installations.
This platform is typically not selected for new developments where full IP infrastructure is available and advanced mobile or cloud-based intercom features are required.
