Learn on for my full evaluate to see why the G400 deserves critical consideration in case you are searching for a wired sensible doorbell.
Design and set up
- Works with PoE or a doorbell transformer
- Wi-Fi or Ethernet connection

At first look, the G400 shares a well-known look with Aqara’s latest video doorbells, though there are a couple of notable variations when you truly deal with it.
The unit measures 140.97 x 52.97 x 32.4mm, making it slimmer than the G410 whereas nonetheless having sufficient presence to keep away from trying overly low cost mounted beside a entrance door.
The general design positively feels extra sensible than luxurious although. The plastic-heavy development lacks the premium really feel of metal-bodied rivals just like the Nest Doorbell Professional or Ring Video Doorbell Elite, and it additionally misses the softer matte end discovered on the G410.
Nonetheless, it feels noticeably sturdier than many low-cost sensible doorbells, and the general development feels sturdy sufficient for long-term out of doors use.
The G400 additionally carries a correct IP65 climate resistance ranking, that means it’s constructed to deal with rain, wind, and basic out of doors publicity all year long.
One of many largest modifications in comparison with the older G4 and G410 fashions is the way in which connectivity works.

With these earlier doorbells, the included chime successfully acted as a bridge between the doorbell and your community. If the chime was unplugged or positioned too distant, the doorbell might lose connection completely.
That setup has been dropped right here and the G400 now connects straight utilizing both dual-band Wi-Fi 6 or Ethernet, so the chime is optionally available reasonably than important. And, as nicely information, you should use Energy over Ethernet (PoE) to energy the doorbell by way of its wired information connection, supplied you’ve got a PoE energy injector.
One other change is that the microSD slot is on the doorbell unit itself now, reasonably than within the chime, as with earlier fashions.

The doorbell itself features a built-in speaker that performs an exterior chime sound when pressed, whereas indoor alerts can come by way of the included chime, suitable sensible audio system, and even Aqara hubs such because the Hub M3 or M1S.
One factor value conserving in thoughts is that whereas the G400 can use current doorbell wiring for energy, it can’t set off your private home’s unique mechanical or digital chime field. These wires are solely used to provide energy to the doorbell itself. This can be a rising change and one which’s barely irritating: in case you’ve already bought the {hardware} there, then why not have the ability to use it?
In contrast to the battery-powered G4, the G400 is wired-only. As talked about, you’ll be able to both energy it by way of a standard 8-24V doorbell transformer or by way of PoE for each information and energy supply.

I examined the G400 utilizing PoE and I really feel prefer it’s one of the best ways to make use of this doorbell, in case your setup permits it.
Not solely does it take away worries about Wi-Fi sign power on the entrance of the home, but it surely additionally delivered noticeably faster response occasions and fully steady connectivity all through my testing interval.
Simply keep in mind that Aqara doesn’t embrace an Ethernet cable or PoE injector within the field, so you will want to offer these your self.
You get two mounting plates within the field: one for flat set up and one other 15-degree wedge mount in case your doorway wants a barely angled view.

Each mounting choices embrace 3M adhesive backing if you wish to keep away from drilling, though Aqara additionally consists of screws and even a tiny screwdriver in case you choose a safer set up.
For PoE setups, Aqara additionally features a rubber sealing block that matches across the Ethernet cable connection to assist preserve climate safety.

My evaluate pattern was mounted quickly throughout testing, so it will clearly look cleaner put in correctly flush in opposition to the wall reasonably than sitting over my previous doorbell’s blue plastic again field.

As soon as powered on, the Aqara House app instantly acknowledged the G400 and guided me by way of setup step-by-step, together with set up ideas and spoken voice prompts straight from the doorbell.

You possibly can technically add the G400 straight into Apple House, though you continue to want to finish Aqara’s personal setup course of first.

One small factor to be careful for: the Aqara QR code and HomeKit QR code sit proper beside one another on the again of the unit, so protecting one whereas scanning the opposite helps keep away from setup confusion.
Options
- 1536 x 2048 decision
- Helps 24/7 recording

As talked about, there’s nonetheless a subscription layer accessible if you need further AI-powered options.
Aqara’s HomeGuardian service provides cloud-based facial recognition, bundle detection, pet detection, car detection, flame alerts, AI-powered search instruments, and 90 days of cloud storage.
It’s a little irritating that a number of the extra superior detections require a paid subscription, particularly when HomeKit Safe Video already handles lots of these AI options domestically for Apple customers.
Nonetheless, the essential half is that the G400 stays absolutely purposeful with out paying additional each month.
The Aqara app itself will really feel acquainted to anybody who has used the corporate’s cameras earlier than.
Reside view masses shortly, snapshots look sharp, and the interface is laid out logically with out changing into overly difficult.

In comparison with older widescreen-style doorbells, it gives a way more sensible view of what’s occurring at your entrance door.
PoE help additionally makes an actual distinction in each day use. Reside view opens shortly, notifications arrive promptly, and all through testing I skilled not one of the connection instability that may generally have an effect on battery-powered fashions or weaker Wi-Fi setups.
If you have already got Ethernet accessible close to your entrance door, this totally seems like one of the best ways to run the G400.
The low-light efficiency is much less spectacular although. Whereas daytime picture high quality is clearly higher than the older G4, nighttime footage can look noticeably darker, and there’s no coloration night time imaginative and prescient help.
It’s nonetheless completely usable, however this stays one space the place dearer premium video doorbells proceed to carry a bonus.
The infrared system itself makes use of refined 940nm IR LEDs, which suggests there is no such thing as a apparent glowing crimson ring seen throughout nighttime operation.
