Replacing an outdated hardwired or audio-only intercom system typically involves upgrading to modern IP-based video intercom platforms that leverage existing structured cabling or utilize modern two-wire configurations. Property managers and homeowners frequently transition to smart video intercoms from manufacturers like Aiphone, DoorBird, or Comelit, which support high-definition video feeds, mobile app integrations, cloud-based access control, and keyless entry credentials such as RFID key fobs or PIN codes. Evaluating your current wiring infrastructure before purchasing ensures a smooth transition and minimizes costly installation labor.
