2026 verdict
Renters on a budget who want neither doorbell wiring nor a monthly fee should pick the TP-Link Tapo D210 over the aosu Video Doorbell R1 Ultra.
It is the more affordable of these two no-subscription video doorbells, its rechargeable battery is rated at 6 months against 90 days, and it adds SmartThings to the Alexa and Google Home support both share, recording 2K to a microSD card you supply. The aosu Video Doorbell R1 Ultra is the higher-resolution camera at 5MP, connects on 5 GHz as well as 2.4 GHz, can also run from doorbell wiring and ships with a base that stores clips and doubles as the chime. Both include a chime, color night vision, free person detection and IP65 weather resistance. Choose the aosu Video Doorbell R1 Ultra for the sharpest picture or a wired install, and the TP-Link Tapo D210 for a cheap, long-running battery doorbell.

What the differences mean
Battery life
The TP-Link Tapo D210 is rated at 6 months per charge and the aosu at 90 days, and some aosu owners report less. For a battery-only install, the Tapo means far fewer trips up the ladder.
Wiring option
The aosu Video Doorbell R1 Ultra can run on existing doorbell wiring as well as on battery. The Tapo is battery only, so it never uses the wiring even when you have it.
Resolution
5MP on the aosu against 2K on the Tapo. Both show a visitor head to toe, but the aosu keeps more detail when you zoom in.
Storage
The aosu records to its included aosuBase Mini, which also rings indoors. The Tapo records to a microSD card you buy, up to 512 GB, and includes its own chime.
Wi-Fi and platforms
The aosu connects on 2.4 or 5 GHz, the Tapo on 2.4 GHz only. The TP-Link Tapo D210 adds SmartThings to the Alexa and Google Home support both have.
Which one to buy if
- you rent and cannot touch the wiring
The TP-Link Tapo D210 runs on a battery rated at 6 months and costs less.
- you want the sharpest image of the doorstep
The aosu Video Doorbell R1 Ultra records 5MP against 2K.
- you have doorbell wiring and want to use it
The aosu can run wired so the battery never runs down; the Tapo cannot be hardwired.
- your home runs on SmartThings
The TP-Link Tapo D210 works with SmartThings, which the aosu does not support.

What owners say
Owners of both doorbells chose them for the same reason, local storage with no monthly fee, and both groups praise sharp video. TP-Link Tapo D210 owners single out on-device person detection at no cost, spotlight color night vision, battery life running from about a month with every detection on to over five months of normal use, and the Ring Call feature that phones them, while complaining about a shallow Alexa integration, people missed further down the path, lagging two-way audio and 30 days of Tapo Care history. aosu Video Doorbell R1 Ultra owners single out the clean install, strong 5MP resolution and responsive support, and their complaints are battery life well below the rating for some, one report of poor human detection, units arriving damaged and a new-build install that needed a resistor.
