What owners say

Owners of both doorbells chose them to avoid a monthly fee, and both groups complain about battery life. Aqara Smart Video Doorbell G4 owners single out setting it up from the Apple Home app, HomeKit Secure Video and durability in extreme heat, and warn that its AA cells drain in weeks, that 2.4 GHz struggles through metal doors and masonry and that it will not record to microSD without internet. Eufy Video Doorbell C31 (with Battery Pack) owners single out a clear 2K image day and night, reliable recording with a Eufy HomeBase and popping the battery out to charge without taking the doorbell down. Their complaints are battery life short of the claims with no low-battery warning, slow notifications and live view, a bulky body and no chime in the box.
