What is an IP Intercom System?
An IP Intercom System is a network-based communication system that allows for audio or video interaction between different points using Internet Protocol (IP). Unlike analog intercoms, which are hardwired and have limited functionality, IP intercoms offer scalability, higher quality, and greater flexibility — all while operating over your existing network.
How It Works: Core Technologies and Protocols
These systems use technologies like SIP (Session Initiation Protocol), TCP/IP, and PoE (Power over Ethernet) to transmit data. They typically include:
-
IP Cameras & Microphones – For two-way communication.
-
Door Stations – Installed at entry points.
-
Master Stations or Mobile Apps – For monitoring and communication.
Central Servers or Cloud Platforms – For controlling and managing users, settings, and logs.
