| description | Smart buzzer systems for apartment buildings, where an intercom station in an apartment unit notifies the user of a request from a guest to unlock the building's door, sends the user's approval of the request to the door, and enables the user and the guest to talk to each other, are disclosed. The smart buzzer systems are enhanced with connectivity with mobile devices and mobile applications as well as automation. The intercom station includes an audio input-output circuit configured to process audio signals, which includes a line input buffer configured to process audio signals from a legacy base microphone through a wiring interface for a legacy intercom system to a processor and a line output driver configured to process audio signals from the processor to the legacy base speaker through the wiring interface for the legacy intercom system. |
