Components of a door phone system

Although there are various types of door phone systems, they all consist of three essential components:

  • Outdoor unit: The outdoor panel is installed near the front door or gate. Sometimes called an intercom doorbell, it includes a series of buttons, each button connecting to a specific unit’s door phone. Additionally, the outdoor panel has a microphone and speaker.
  • In-unit devices: In-unit devices are the core of the system — they’re the actual “door phone” component of the system. They’re installed inside every unit within a property. Many door entry phones include wired telephone handsets. Tenants press either ‘9’ on the keypad or a designated ‘door open’ button to unlock the door remotely.
  • Door release: You’ll need a door release mechanism with either an electric or magnetic lock so tenants can remotely open the door once they’ve granted visitors access.
