Aqara Smart Video Doorbell G4 vs Eufy Video Doorbell C31 (with Battery Pack)

The Aqara Smart Video Doorbell G4 is the stronger all-rounder. It supports more platforms (including Apple HomeKit with HomeKit Secure Video) and adds custom ringtones, voice changing and familiar-face alerts, all without a subscription. The Eufy Video Doorbell C31 (with Battery Pack) counters with sharper 2K video and a higher owner rating, so it is close if picture quality is your priority.

Smart-home reach versus video resolution. The G4 works with Apple HomeKit, Google, Alexa, Home Assistant and IFTTT and adds extras like custom ringtones and voice changing, while the C31 skips HomeKit and Matter but shoots at 2K rather than the G4's 1080p.

Yes. The Aqara G4 stores video on microSD plus 7 days of free cloud, and the Eufy C31 records locally to microSD or a Eufy HomeBase with no monthly fee. Cloud plans are optional on both rather than required to view footage.

Only the Aqara Smart Video Doorbell G4, which supports Apple HomeKit including HomeKit Secure Video. The Eufy Video Doorbell C31 (with Battery Pack) works with Google Home, Alexa and Home Assistant, but has no HomeKit or Matter support.

Apple households and anyone who wants the broadest platform support with fee-free recording, plus perks like custom indoor and outdoor ringtones, voice changing and familiar-face detection. It is the pick when smart-home flexibility outweighs raw resolution.

Buyers who want the sharpest image and plan to record locally, especially existing Eufy HomeBase owners in Google or Alexa homes. Its 2K video and higher owner rating make it a good fit if you do not need HomeKit or custom ringtones.
