What the differences mean

Cameras

The aosu Video Doorbell R1 Ultra uses one 5MP camera with a 166 degree diagonal view. The Eufy Video Doorbell E340 adds a second camera angled down at the doorstep, which is what lets it see a parcel on the mat that a single lens can miss.

Indoor chime

The aosu Video Doorbell R1 Ultra ships with its base station, which doubles as the indoor chime. The Eufy Video Doorbell E340 has no chime in the box, so it rings indoors only with Eufy's add-on chime or a smart speaker.

Free detection

On the Eufy Video Doorbell E340, person, package and familiar face alerts are included. On the aosu Video Doorbell R1 Ultra, person alerts are free, but package and familiar face detection need the optional cloud plan.

Wi-Fi

The aosu Video Doorbell R1 Ultra works on 2.4 and 5 GHz Wi-Fi; the Eufy Video Doorbell E340 is 2.4 GHz only, which matters if your router is set to 5 GHz or the 2.4 GHz band is crowded.

Which one to buy if

What owners say

Owners of both doorbells bought them for the same reason: local recording with no monthly fee. After that they notice different things. aosu Video Doorbell R1 Ultra owners who tried Eufy, Botslab and Lorex call its install the cleanest of the group, praise the 5MP image and describe support that replaced a faulty unit; their complaints are battery life below the rating, human detection that misses people and a few units that arrived damaged. Eufy Video Doorbell E340 owners single out the dual camera, which shows the parcel on the ground as well as the person at the door, and AI that reliably flags deliveries, plus colour night vision. They complain that it does not ring indoors without an add-on chime or a smart speaker, that the app feels clunky and that false package alerts come in waves.
