What the differences mean

How it gets power

The Aqara Doorbell Camera G400 (Wired) has no battery mode: it runs on PoE or existing 8-24V doorbell wiring and records around the clock. The Ring Battery Doorbell 4K Pro runs on a removable battery pack, which is the whole point for a rental or a door with no wiring, and it can optionally be hardwired.

Where the video is kept

The Aqara Doorbell Camera G400 (Wired) records to a microSD card of up to 512 GB, can back up to an SMB NAS and streams over RTSP and ONVIF, so it works with no subscription. The Ring Battery Doorbell 4K Pro has no slot and no onboard storage, so a Ring plan is the only way to save a clip.

Resolution and night vision

The Ring Battery Doorbell 4K Pro shoots 4K HDR and keeps colour in low light before falling back to black and white, with a square 140 by 140 degree view. The Aqara Doorbell Camera G400 (Wired) shoots 2K in a taller 3:4 frame with 940nm infrared, so its night footage is black and white only, though the wider diagonal view helps keep a parcel in shot.

Platforms and ecosystems

The Aqara Doorbell Camera G400 (Wired) works natively with Apple Home, Google Home, Alexa, SmartThings and Home Assistant. The Ring Battery Doorbell 4K Pro works with Alexa and, through the community ring-mqtt integration, Home Assistant, but has no Apple Home, Google Home, SmartThings or Matter support.

AI detections and the subscription line

Both brands gate package, vehicle, animal and face detection behind a plan. The difference is what breaks without one: the Aqara Doorbell Camera G400 (Wired) still keeps motion and person detection local and records to its card, while the Ring Battery Doorbell 4K Pro keeps no recording of any kind until you pay.

Which one to buy if

What owners say

Owners of both doorbells lead with the picture and the speed of the alerts, but they part ways on storage and wiring. Aqara Doorbell Camera G400 (Wired) owners who came from Ring and Nest call the HomeKit Secure Video live view and the doorbell press arriving as a video call the highlight, and they like running PoE or existing wiring with no battery to charge. Their complaints are a bundled chime they find too quiet to hear across a house and a fussy transformer when PoE is not used. Ring Battery Doorbell 4K Pro owners single out the 4K detail, saying they can now read text on a package label or a shirt, plus the colour night vision and the radar motion alerts that describe what was seen. The recurring gripe there is that nothing is saved without a subscription, since the doorbell has no local storage at all.

Frequently Asked Questions

Which is better, the Aqara Doorbell Camera G400 (Wired) or the Ring Battery Doorbell 4K Pro?

The Aqara Doorbell Camera G400 (Wired) is the better all-round pick for a wired door, since it records locally without a subscription and works with Apple Home, Google Home, Alexa, SmartThings and Home Assistant. The Ring Battery Doorbell 4K Pro wins on image quality with 4K HDR video and on flexibility, because it runs on a battery for doors that have no wiring, at the cost of a required plan for any recording.

Do these doorbells need a subscription?

Not for basic use. The Aqara Doorbell Camera G400 (Wired) records 24/7 to a microSD card of up to 512 GB and can back up to a NAS, with motion and person detection running on the device for free. The Ring Battery Doorbell 4K Pro has no local storage, so a Ring plan is required to save any video or to unlock person, package, vehicle and Familiar Faces alerts.

Does the Aqara Doorbell Camera G400 (Wired) work with Apple Home?

Yes. It supports HomeKit Secure Video natively, so you can view live video, get notifications and use two-way audio in the Apple Home app, although HomeKit Secure Video needs an iCloud+ plan and an Apple home hub. The Ring Battery Doorbell 4K Pro does not support Apple Home.

Can the Ring Battery Doorbell 4K Pro run without a battery or wiring?

No. The Ring Battery Doorbell 4K Pro runs on its rechargeable Quick Release Ultra battery pack or on optional 8-24V hardwiring, and the Aqara Doorbell Camera G400 (Wired) is wired only, taking PoE or existing doorbell wiring. Neither works without one of those power sources, though only the Ring offers a battery at all.

Which has the wider field of view?

The Aqara Doorbell Camera G400 (Wired) covers a wider 165 degree diagonal in a tall 3:4 frame that keeps a parcel in shot. The Ring Battery Doorbell 4K Pro uses a square 140 by 140 degree view. Both are aimed at showing a visitor head to toe rather than only their face.

Who should buy the Aqara Doorbell Camera G400 (Wired)?

An Apple household or a tinkerer with wiring at the door, who wants local recording without a monthly fee, PoE power and RTSP and ONVIF streams for Home Assistant, Frigate or an NVR. The Ring Battery Doorbell 4K Pro is the pick when the door has no wiring and 4K detail is worth a plan.
