aosu Video Doorbell R1 Ultra vs Eufy Video Doorbell E340

Full Smart Doorbells comparison in 2026

Updated September 2026
Data from Amazon and official aosu and Eufy sites.
2026 verdict
Two subscription-free doorbells at a similar price, and aosu Video Doorbell R1 Ultra edges it on camera and connection: a 5MP sensor with a 166 degree diagonal view, dual-band Wi-Fi against 2.4 GHz only, customisable motion zones, radar plus PIR and AI detection to cut false alerts, and an included aosuBase Mini with 8GB and 60-day loop recording. Eufy Video Doorbell E340 answers with an idea rather than a spec sheet: two cameras, a main 2K lens for visitors and a second angled down at the doormat, so packages are always in frame, backed by 8GB of internal storage with no fees, colour night vision, package, person and familiar-face detection, automatic replies, 24/7 history and Home Assistant support alongside Google Home and Alexa. It needs a separate chime to ring indoors, has no microSD slot and no HomeKit or Matter. Choose Eufy Video Doorbell E340 if watching the doorstep for parcels is the whole point; choose aosu Video Doorbell R1 Ultra for the sharper sensor, 5 GHz Wi-Fi and custom detection zones.

Frequently Asked Questions

Which is better overall, the aosu Video Doorbell R1 Ultra or the Eufy Video Doorbell E340?

aosu Video Doorbell R1 Ultra narrowly, on its 5MP sensor, dual-band Wi-Fi and customisable motion zones, with 60 days of included local recording. Eufy Video Doorbell E340 wins on integrations, adding Home Assistant, and on its second downward camera and automatic replies.

What is the dual camera on the E340 for?

Eufy Video Doorbell E340 pairs a main 2K camera for visitors with a second camera angled at the ground, so a parcel left on the doormat is always visible along with a head-to-toe view. aosu Video Doorbell R1 Ultra uses a single 5MP camera with a tall 4:3 frame instead.

Do either need a subscription?

Neither for recording. Eufy Video Doorbell E340 stores footage in 8GB of internal memory or on a eufy HomeBase, and aosu Video Doorbell R1 Ultra records 60 days to its included base station, though its package and familiar-face alerts require a plan.

Which is easier to install and hear?

aosu Video Doorbell R1 Ultra ships with its base station, which doubles as the chime. Eufy Video Doorbell E340 needs a separate add-on chime to ring indoors, which owners flag as an extra cost, and its body is bulky.

Who should buy the Eufy Video Doorbell E340?

Anyone whose main worry is parcel theft, since the second camera watches the doorstep continuously, and Home Assistant users who want local recording with no fees. For a sharper single camera, 5 GHz Wi-Fi and adjustable motion zones, aosu Video Doorbell R1 Ultra is the better fit.
