The UniFi Protect G4 Doorbell Pro is best for UniFi Protect users who want dual cameras, fast notifications, and enterprise grade software, and who are willing to pay a premium and use a fully wired setup.
Dual cameras provide a wide main view plus a dedicated downward package view, with picture-in-picture playback that keeps package awareness clear despite the low frame rate.
A phone-call style response option lets the doorbell connect more directly when pressed, offering quicker conversations than relying solely on the standard app live view.
Doorbell alerts arrive quickly and package notifications are reasonably fast, though package alerts only fire when boxes appear within the downward package camera’s view.
Protect’s enterprise-grade feel and robust controls stand out, but newer 2.0 additions like package detection, device groups, and notifications still show some rough edges.
The Pro commands a higher price than many competitors, and while dual cameras and USB C power can justify the premium for dedicated UniFi Protect users, many buyers will find it expensive even compared with other POE options.
