aosu Video Doorbell R1 Ultra vs Eufy Video Doorbell C31 (with Battery Pack)

aosu Video Doorbell R1 Ultra, thanks to a 5MP sensor, dual-band Wi-Fi, colour night vision, custom motion zones and 60 days of included local recording. Eufy Video Doorbell C31 (with Battery Pack) wins on price and on Home Assistant support with automatic replies.

No for the basics. aosu Video Doorbell R1 Ultra records to its included base station, though package and familiar-face alerts need a plan. Eufy Video Doorbell C31 (with Battery Pack) records to microSD or a eufy HomeBase with no monthly fee at all.

aosu Video Doorbell R1 Ultra uses a 5MP sensor with a 166 degree diagonal view plus colour and black-and-white night vision. Eufy Video Doorbell C31 (with Battery Pack) shoots 2K but does not document night vision modes or a field of view.

aosu Video Doorbell R1 Ultra supports both 2.4 and 5 GHz Wi-Fi, which helps on busy networks. Eufy Video Doorbell C31 (with Battery Pack) is 2.4 GHz only, and it also lacks HomeKit and Matter, as does the aosu.

Owners of a eufy HomeBase who want cheap 2K recording with no fees, a quick-release battery and Home Assistant integration, and who can live with modest battery life and a bulky body. For a sharper camera and better detection, aosu Video Doorbell R1 Ultra is the stronger choice.
