Aqara Doorbell Camera G400 has been reviewed for its full support for HomeKit Secure Video and support for Power over Ethernet (PoE), dual-band Wi-Fi 6, and 24/7 stability. The G400 also supports local AI detection and a tall aspect ratio designed to spot packages. While the camera is a 2K camera, Apple limits HomeKit secure Video to 1080p if used simultaneously, the lower resolution applies to both platforms. To get the most out of the G400 in Apple Home, you will need an iCloud+ subscription and a HomeKit hub (HomePod mini or Apple TV). The resolution cap is frustrating but the seamless integration into the Apple ecosystem allows for rich notifications on your iPhone and Apple Watch. The camera also supports night vision and can record continuously to a microSD card up to 512GB.
