Introduction: The Silent Evolution of Entry Systems
In an era where doorbells stream 4K video and buildings “think,” Power over Ethernet (PoE) intercoms are quietly revolutionizing security infrastructure. By merging power, data, and intelligence into a single Cat6 cable, these systems are dismantling decades-old analog paradigms. This deep dive explores how PoE intercoms aren’t just upgrading door entry—they’re architecting the nervous system for smart cities.
