Aqara Doorbell Camera G400 with Chime, Wired/PoE, HomeKit Secure Video,IP65

Hardwired video doorbell setups often force homeowners to choose between smart home compatibility and local data ownership, but the Aqara G400 manages to bring both worlds together. Designed for homeowners seeking continuous monitoring, it delivers versatile connectivity by running over high-efficiency PoE or tapping into existing 8-24V AC/DC low-voltage doorbell lines. The inclusion of dual-band 2.4GHz and 5GHz Wi-Fi 6 with WPA3 encryption ensures the wireless link stays stable, while its IP65 weatherproof rating keeps it operating normally through wet, windy weather.

Visual coverage centers on a 2K HD sensor paired with a 165-degree field of view. Unlike traditional 16:9 cameras that cut off the welcome mat, its vertical 3:4 aspect ratio captures packages resting on the ground as well as tall visitors standing right at the threshold. After dark, night vision relies on 940nm infrared LEDs. Because this specific wavelength emits virtually no visible glow, the camera provides bright footage without broadcasting a red light that alerts passersby or bothers next-door neighbors.

For day-to-day smart home use, integration runs deep. The camera functions with Apple HomeKit Secure Video, allowing encrypted storage, iCloud recording, and alerts across Apple hardware. It is also compatible with Alexa, Google Assistant, and SmartThings, while advanced network setups can tap into RTSP, ONVIF, and dedicated NVRs. Built-in local AI handles person recognition and zone intrusion right on the device, eliminating unnecessary alerts without requiring cloud subscriptions. If someone presses the button, you can reply via a voice-changing intercom or preset automated responses, while cloud package identification and face recognition track daily deliveries.

There are a few hardware and platform limitations to keep in mind before installing. When running through Apple HomeKit, the native 2K resolution steps down to 1200p, a limit that also extends to the Aqara Home app whenever both platforms operate at the same time. In addition, HomeKit Secure Video requires an Apple home hub and an active iCloud+ plan. Local continuous recording requires buying your own microSD card, as the 512GB-capable slot comes empty, and there is no battery option for homes lacking transformer or ethernet wiring.

Verdict: The Aqara G400 video doorbell camera is an outstanding choice for smart homes invested in Apple HomeKit, advanced NVR setups, or local network storage. Buyers without doorbell wiring or an ethernet drop should look toward battery-operated alternatives instead.

A great fit if you:

• Rely on Apple HomeKit Secure Video and want end-to-end encrypted video clips sent straight to your personal Apple devices.
• Have an existing low-voltage doorbell line or a PoE ethernet cable run directly to your front entryway.
• Prefer continuous 24/7 video recording stored privately on a local microSD card or an SMB-compatible home NAS server.
• Want to clearly monitor porch parcels on the ground using an ultra-wide vertical 3:4 camera perspective.

Consider something else if you:

• Rent your home and need a battery-powered wire-free doorbell that installs without existing low-voltage wiring or running network cables.
• Demand full 2K resolution strictly inside Apple HomeKit without having your stream limited to 1200p.

Confirm on the listing:

• Check your existing transformer voltage to verify it falls within the required 8–24V AC/DC range if you plan on reusing current wiring.
• Check whether you have an active Apple home hub and an eligible iCloud+ plan if you intend to record using HomeKit Secure Video.
• Confirm you have a compatible high-capacity microSD card on hand if you plan to save continuous video locally without relying entirely on a NAS.
• Measure your door trim and mounting area to see if the included wedge kit provides the angle necessary for your walkway.

How to compare your options: Video doorbells mainly differ by how they receive power, where they store recorded video, and which smart platforms they support. This model stands out by providing both PoE and standard transformer wiring alongside local storage routes like micro-SD and SMB network backups, avoiding locked-in cloud fees. When comparing units, weigh whether you prioritize simple wire-free mounting or the stability of constant power and flexible local streaming protocols like RTSP and ONVIF.

Mount the camera using the included wedge kit if your doorway sits off-center or faces a side wall, ensuring the 165-degree lens has an unobstructed view of both the ground and arriving visitors. Plug in the included chime in a central living area where incoming doorbell rings can be heard clearly throughout the home.

Take advantage of on-device intelligence by configuring designated detection zones and person recognition in your settings, which keeps false alerts down without relying on external cloud processing. If you prefer keeping footage off third-party servers, install a microSD card up to 512GB for round-the-clock recording, and set up an automatic backup route to an SMB-compatible NAS on your local network.

For households using other Aqara hardware, link the doorbell with compatible screens such as the MagicPad, Panel Hub S1 Plus, or Thermostat Hub W200 to view live camera feeds and visitor snapshots from interior rooms.

Does this doorbell camera run on batteries?
No, it requires hardwired power. It operates using either an ethernet cable via Power over Ethernet (PoE) or existing 8–24V AC/DC low-voltage doorbell wiring.

What is included in the package?
The package comes with the G400 doorbell camera, an indoor plug-in chime, and a wedge kit for mounting. Storage media like the microSD card are not included.

Does the video stream in full 2K resolution in Apple HomeKit?
No, resolution is restricted to 1200p when connected to Apple HomeKit. That same 1200p limitation also carries over to the Aqara Home app if both ecosystems are operating at the same time.

What are the requirements for HomeKit Secure Video?
You will need an active Apple home hub (such as an Apple TV or HomePod) and an active Apple iCloud+ subscription plan to enable encrypted video recording and notifications.

Can I store continuous video without paying for a cloud plan?
Yes, the camera supports continuous 24/7 recording directly onto a microSD card up to 512GB, and it can also automatically back up local footage to an SMB-compatible NAS server.
