intercom systems
Internal voice networks
Intercom systems are communication networks that allow voice transmission between different locations within a building or complex.
They typically connect a central station to multiple endpoints—doorways, rooms, or security checkpoints: The intercom system lets us buzz visitors in.
Modern systems may include video capability, integration with smartphones, or connection to building-wide PA announcements.
