The newest Ring doorbell is the Ring 4, which was launched in 2021. It offers 1080p resolution, a 160-degree field of view, two-way talk, and full-color preroll, among other features. The Ring 4 can be used wirelessly with its battery or wired, but it requires wired installation. Other Ring doorbells available include the Battery Doorbell Plus, Video Doorbell Pro, Video Doorbell Pro 2, and Video Doorbell (2nd Generation).
