What the Aqara G400 doorbell handles
- Best for a wired doorbell location with 8-24V AC/DC or PoE available.
- 2K sensor, 165-degree view, 940nm IR night vision.
- HomeKit Secure Video needs iCloud+ and an Apple home hub.
The Aqara Doorbell Camera G400 with Chime is built for the everyday job of watching your front door. It captures a 2K HD view with a 165-degree field and a 3:4 aspect ratio, so you see a package on the step and a face at the door in the same frame. Nearly invisible 940nm infrared LEDs handle night vision without a red glow.
It runs on wired power, either PoE or your existing 8-24V AC/DC doorbell wiring, so you skip battery swaps. Wi-Fi 6 on 2.4GHz and 5GHz keeps the feed stable, and the included plug-in chime gives you an indoor ring.
We'd consider this a strong fit if you want on-device person and zone detection, custom quick replies, and a voice-changing intercom for answering without opening the door. Local processing means alerts arrive without sending footage to the cloud first. If you use Apple Home, HomeKit Secure Video requires both an iCloud+ subscription and an Apple home hub, and Apple Home caps resolution at 1200p. For Aqara Home, that same 1200p limit applies when both platforms run at once.
What $84.99 gets you and how the comparison works
The G400 with Chime is $84.99. That is $10.72 below the typical price over the last 90 days, a saving of about 11%. Whether that gap is enough to move now depends on how soon you want the camera watching your entry.
The package includes the doorbell, a wedge kit for angling the view, and a plug-in indoor chime. You can record 24/7 to a microSD card up to 512GB, which is not included, or back up footage to an SMB-compatible NAS.

Placement, power and local storage checks
The IP65 rating means the G400 is built for outdoor wind and rain, so mounting it at your entryway is fine. Use the wedge kit if your door faces a wall or you need a better angle on the approach path.
Before you buy, confirm your existing doorbell wiring supplies the right voltage, or that you can run a PoE cable to the spot. If you plan to use HomeKit Secure Video, check that you have the required iCloud+ subscription and an Apple home hub in the house, since the encrypted recording runs through those services. For local recording, decide whether a 512GB microSD card is enough or whether you want the automatic NAS backup.
The G400 also works with Aqara Home screens like the MagicPad or Panel Hub S1 Plus, and can send visitor snapshots to the Thermostat Hub W200, though those accessories vary by region.
When the G400 is the wrong doorbell
If you rent and cannot modify the doorbell wiring or run a PoE cable, this is not a simple install. The same goes if you expect full 2K resolution inside Apple Home, since HomeKit limits it to 1200p and that cap also applies in Aqara Home when both platforms are active.
Skip it if you want a battery-powered doorbell or if you are not prepared to supply your own microSD card for 24/7 local recording. For those setups, a wire-free model may suit you better.
