Aqara Doorbell Camera G400 Select, the first always-on doorbell camera with PoE or wired power, keeps your doorstep secure day and night. See every visitor and package in crisp 2K with a 165° ultra-wide vertical view, using invisible infrared night vision. Smart local AI detects people, motion, and custom intrusion zones, sending alerts only when it matters. Unlock, talk, or view live from your favorite smart home apps, or connect with Aqara devices for smarter deliveries. Weatherproof, tamper-proof, Wi-Fi 6 ready, and fully compatible with HomeKit, Alexa, Google, and SmartThings.

• From Face to Floor: View People and Packages: With a 165° ultra-wide vertical view and a 3:4 aspect ratio, the Doorbell Camera G400 Select shows your entire doorway from top to bottom, so you never miss visitors or packages. Sharp 2K resolution reveals faces and delivery details clearly, with adjustable brightness for any lighting. At night, invisible 940nm infrared night vision keeps your doorstep clearly monitored—without drawing attention.

• No Battery to Charge, Solid Hardwired Power: Choose the installation method best suited to your home. PoE power provides a simple and stable installation—a single Ethernet cable transmits both power and data, ensuring reliable operation around the clock. Alternatively, you can connect directly to your existing 8-24V AC/DC doorbell wiring for continuous power without rewiring①. Either way, the Doorbell Camera G400 Select maintains 24/7 power, ensuring your door is always under surveillance.

• Detect Local, with Zone Intrusion: Built-in local AI detects motion and recognizes people without relying on the cloud, so alerts are fast, private, and always available. You can define your intrusion zones by simply dragging and resizing detection areas, and get notified instantly when someone enters or leaves those spaces. This way, you’re alerted only to meaningful activity around your door—no unnecessary notifications, just the moments that matter.

• Reply Faster, Ring Smarter: With the Doorbell Camera G400 Select, you can handle instant replies for unexpected guests through preset or custom quick replies, like “Leave the package, thanks” or “Be right there,” without opening a full voice call. You can also control how many times the doorbell rings, so you never miss an important visitor—or annoy the household with too many rings. Fast, effortless, and always in control.

• Works with Your Smart Home Favorites: The Doorbell Camera works with major smart home platforms—Apple Home② (full HomeKit Secure Video③ with two-way audio), Google Home, Alexa, and SmartThings—so you can view live video, get notifications, and control your doorbell from the apps you already use. For advanced setups, it also supports Home Assistant via RTSP/ONVIF integration, giving you flexibility for professional or customized smart home systems.

• Excellent Aqara Home Integration: Works seamlessly with Aqara smart locks and smart screens, allowing you to view visitors in real time, talk to them, and unlock the door directly. Stream live video to Panel Hub S1 Plus or view visitor snapshots on Thermostat Hub W200. Built-in privacy masking and voice changing features help you confidently manage deliveries and visitor access.

• HomeGuardian Sees What Matters Most: HomeGuardian④ makes your camera work smarter, helping you focus on what truly matters and ignore what doesn’t. With smarter, deeper detection and intelligent automation, it fills the gaps that local-only setups can’t—so you can know, find, and act instantly when it counts. Every G400 purchase includes a free 3-month HomeGuardian Plan, giving you access to advanced cloud-based insights and smarter protection right out of the box.

• 24/7 Local Storage, with NAS and ONVIF Support: Never miss a thing. Our doorbell offers 24/7 continuous recording directly to a microSD card⑤. For added peace of mind, all local footage automatically backs up to your SMB NAS⑥ server, keeping your video safe and secure.

• Built for the Outdoors, Ready for Trouble: This doorbell is IP65 waterproof and dustproof, ensuring reliable operation in any weather conditions. Its built-in tamper-proof alarm functions will trigger instantly if anyone attempts to remove or interfere with the doorbell, helping to protect your home security around the clock.
