Ubiquiti G4 Doorbell
The Ubiquiti G4 Doorbell is a mixed experience. It integrates seamlessly into UniFi Protect with good picture quality, handles existing doorbell wiring better than the Ring and Skybell it replaced, and—critically—requires no monthly subscription for cloud storage since recordings go to your local Protect storage. But persistent software limitations undermine the hardware. Protect treats it like a camera rather than a dedicated doorbell, so you must stay actively signed into the app to receive notifications—and the app will sign you out. Cold weather kills reliability below freezing, WiFi signal through exterior walls is a constant struggle, and the optional chimes are disappointingly quiet. My advice: treat it as a camera that happens to be mounted at your front door, not as a reliable communication device.
