2026 verdict
Dual-band Wi-Fi at a distant porch is why the aosu Video Doorbell R1 Ultra is the stronger doorbell here.
It stores clips on the device, lists 5 MP video with color night vision, a chime in the box, and both a battery and a wired connection. The Eufy Video Doorbell S220 answers with a published 6 month battery, a lower price, and local recording through a eufy HomeBase rather than a slot in the doorbell. It is 2.4 GHz only and does not list color night vision. Pick the aosu Video Doorbell R1 Ultra for onboard storage and 5 GHz. Pick the Eufy Video Doorbell S220 if a HomeBase is already in the house.

What the differences mean
Where the clip is stored
The aosu Video Doorbell R1 Ultra lists internal storage and event history, including offline events, and it does not have a microSD slot. The Eufy Video Doorbell S220 lists no internal storage and no microSD slot. Its own write-up says it is an add-on that needs a eufy HomeBase and is not a standalone doorbell, with recording kept on that base. Both list a cloud option as subscription required. Neither lists 24/7 video history. 24/7 live view is not listed for the aosu and is not documented for the S220.
Battery rating
The Eufy Video Doorbell S220 publishes 6 months of battery life and lists wiring as optional. The aosu Video Doorbell R1 Ultra publishes 90 days, and it lists both a rechargeable battery and a wired connection. On the sheet, the Eufy is the longer-lived pack. Real reports in both write-ups are less tidy than those ratings, so treat the figures as the manufacturer's claim, not a promise for a busy porch.
Radio, night and resolution
The aosu Video Doorbell R1 Ultra uses 2.4 GHz and 5 GHz, lists 5 MP video that also counts as 2K, color night vision, and a 166-degree diagonal view. The Eufy Video Doorbell S220 is 2.4 GHz only, lists 2K, and has black and white night vision without color night vision. Field of view is not documented for the S220. HDR is not documented for either, so it decides nothing. Weather resistance is IP65 on the aosu and simply listed as supported on the Eufy, with no rating published.
Alerts and apps
Both list people and motion, Google Home and Alexa. Home Assistant is not documented for either, so neither is credited or faulted for it. The aosu Video Doorbell R1 Ultra lists package and familiar-face alerts behind a subscription, and an included chime. The Eufy Video Doorbell S220 does not list packages, animals, vehicles or familiar faces. Whether it includes a chime is not documented. Neither lists Apple Home, SmartThings or Matter. Automatic replies are not documented for either doorbell.
Which one to buy if
- the porch is far from the router and you want clips in the doorbell
The aosu Video Doorbell R1 Ultra lists 5 GHz and internal storage, plus color night vision and a chime in the box.
- you already own a eufy HomeBase and want the longer battery rating
The Eufy Video Doorbell S220 is the HomeBase add-on with a published 6 month battery, against 90 days on the aosu Video Doorbell R1 Ultra.
- you need color night vision on a battery doorbell
Color night vision is listed on the aosu Video Doorbell R1 Ultra and not on the Eufy Video Doorbell S220, which stays black and white after dark.
- you want the more affordable of the two and can stay on 2.4 GHz
The Eufy Video Doorbell S220 is the lower priced doorbell here. It is 2.4 GHz only, and it needs a HomeBase rather than storing video inside the doorbell.

What owners say
Owners of the aosu Video Doorbell R1 Ultra bought it to avoid another monthly fee and to keep video locally. They mention an easy install, 5 MP that holds up, and support that replaced a bad unit. Battery life is the uneven part: the sheet says about 90 days, and some owners say the charge falls short or that a hardwired unit stopped charging after a couple of years. Human detection also draws at least one clear complaint. Eufy Video Doorbell S220 owners praise years of updates, sharp 2K, and battery life from a couple of months in a busy spot to much longer on a quiet door, recorded on a HomeBase with no fee. They also call two-way talk delayed, and the write-up says that doorbell is an add-on that is not standalone.
