It shoots 2K in a 3:4 head-to-toe frame, adds PoE, Ethernet and dual-band Wi-Fi 6 with WPA3, and keeps local recording on a microSD card of up to 512 GB with NAS backup. The Aqara Smart Video Doorbell G4 is the cheaper option and also supports HomeKit Secure Video, but its 1080p image, 2.4 GHz-only Wi-Fi and heavy AA-battery drain are the complaints owners repeat, even though it can be hardwired. Choose the Aqara Doorbell Camera G400 (Wired) if you have wiring at the door, or the Aqara Smart Video Doorbell G4 if you need a battery doorbell on a tight budget.

What the differences mean

Resolution

The Aqara Doorbell Camera G400 (Wired) records 2K at 1536 x 2048 in a 3:4 frame, while the Aqara Smart Video Doorbell G4 is 1080p. If you want to read a parcel label or a plate, the newer wired model has the sharper sensor.

Power

The Aqara Doorbell Camera G400 (Wired) has no battery mode at all and takes PoE or 8-24V wiring. The Aqara Smart Video Doorbell G4 runs on six AA batteries or wired power, which is what lets it go on a door with no wiring, at the cost of frequent recharges.

Connectivity

The Aqara Doorbell Camera G400 (Wired) supports Ethernet, dual-band Wi-Fi 6, Bluetooth and RF433 for its chime. The Aqara Smart Video Doorbell G4 is 2.4 GHz Wi-Fi only, which owners report struggling through metal doors and masonry walls.

Detection on battery

Both have local person detection and customizable automations. On the Aqara Smart Video Doorbell G4, motion detection weakens in battery mode, so wiring it is strongly recommended; the Aqara Doorbell Camera G400 (Wired) has no such trade-off because it is always powered.

Chime

Both ship with a chime. The Aqara Smart Video Doorbell G4 chime is a loud 95 dB repeater that also strengthens the connection, while owners of the Aqara Doorbell Camera G400 (Wired) often call its bundled chime too quiet to hear across a house.

What owners say

Owners of both Aqara doorbells prize the same thing: native HomeKit Secure Video with no subscription. Aqara Doorbell Camera G400 (Wired) owners describe fast, reliable notifications, an install that often takes about fifteen minutes on existing wiring, and a head-to-toe view that finally captures a parcel on the step; their complaints center on the quiet bundled chime and subscription-gated cloud AI. Aqara Smart Video Doorbell G4 owners praise how easily it installs wired or on battery, the loud chime and the free microSD plus seven-day cloud storage, but they report heavy AA-battery drain, weaker motion detection on battery, 2.4 GHz Wi-Fi that struggles through metal or masonry, and buggy software.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
