What Is an Audio Door Phone?

An Audio Door Phone is a two-way communication system that includes:

• An outdoor unit: Installed at the entrance, with a microphone and speaker.

• An indoor unit: Installed inside the premises, also with a microphone, speaker, and sometimes a call button or receiver.

How It Works

1. The visitor presses a call button on the outdoor unit.

2. The resident hears a ring or alert on the indoor unit.
