What is gatephone-concept?

GatePhone Concept is a reference project that shows how to build a smart video doorbell system that behaves like a real phone call on an iPhone. When someone rings the doorbell, instead of a normal app notification, the iPhone rings the way it would for a regular phone call. Answering it opens a live video stream from a UniFi Protect camera, a home security camera system, and shows buttons for actions such as opening a gate. This is not a finished, ready to use product. The author has deliberately stripped out anything private, including real authentication code, Apple push notification credentials, production web addresses, API keys, and any actual home automation rules. What remains is the overall architecture and the connection points where someone would plug in their own systems. The flow works like this: a doorbell event or automation trigger starts a call session on a backend server. That server sends a special Apple push notification used for VoIP calls to the chosen recipient's iPhone. The iPhone's built in CallKit framework shows the native incoming call screen, just like a normal phone call. Once answered, a SwiftUI screen opens a live camera stream from UniFi Protect over a WebSocket connection, along with command buttons the user can tap, such as one to open a gate. The repository includes an example Node.js backend built with Express, sample iOS Swift files for the call handling and camera player, and documentation covering the architecture, API, iOS side, and security considerations. A quick demo lets you run the backend locally and trigger a fake doorbell call, though the push notification adapter only logs what it would send rather than contacting Apple's servers. This project has 2 stars and is best suited for developers who already have their own authentication, camera, and automation systems and want a starting architecture to adapt, rather than someone looking for something to install and use immediately.
