What the differences mean

Power

The Aqara Doorbell Camera G400 (Wired) runs only on PoE or 8-24V doorbell wiring, so a power cut stops it. The Eufy Video Doorbell E340 runs on its battery or on wiring and keeps recording when the power drops.

Local recording

The Aqara records 24/7 to a microSD card of up to 512 GB and backs up to an SMB NAS. The Eufy keeps clips on a fixed 8 GB of built-in storage with no card slot, so a eufy HomeBase is the way to more room.

Smart alerts

The Eufy detects people, packages and familiar faces without a subscription. The Aqara detects motion and people locally for free, but packages, vehicles, animals and faces need a HomeGuardian plan.

Smart home platforms

The Aqara adds HomeKit Secure Video, SmartThings and RTSP and ONVIF for Home Assistant and NVRs. The Eufy works with Google Home, Alexa and Home Assistant, with no Apple Home support.

Night vision and network

The Eufy sees in colour at night; the Aqara uses black and white infrared only. The Aqara joins 2.4 and 5 GHz Wi-Fi 6 or Ethernet, while the Eufy is 2.4 GHz only.

Which one to buy if

What owners say

Owners of both doorbells value recording without a monthly fee and an install that goes quickly. Aqara Doorbell Camera G400 (Wired) owners put Apple Home first, describing live view that opens almost instantly and doorbell presses arriving as a video call, and they like PoE for ending battery care, plus the RTSP feed for a NAS. Eufy Video Doorbell E340 owners single out the second camera that shows packages on the step and accurate delivery alerts, with sharp colour night vision. The complaints differ too. Aqara owners find the bundled chime too quiet, the transformer fussy and night vision black and white only, and note that package and face detection need a plan. Eufy owners say it does not ring indoors without the add-on chime or a smart speaker, mention a clunky app and some false package alerts, and call the body bulky.
