The Aqara Doorbell Camera Hub G410 serves as both a security camera and a central smart home controller. It captures video in 2K resolution, which provides clear imagery for identifying visitors, and utilizes a built-in mmWave radar for precise presence detection. On-device AI handles face recognition and loitering detection, while the two-way audio system includes a voice modification feature for added privacy. The accompanying indoor chime reaches 95 dB and doubles as a Matter controller, Zigbee hub, and Thread border router to manage your connected devices. Designed for versatility, the doorbell can be powered by 12V-24V AC/DC wiring or by six replaceable AA alkaline batteries that last up to five months. Its black and gray housing measures 141.5 x 65 x 30.4 mm and is built to operate in temperatures ranging from -18°C to +50°C. You can store recordings locally on a microSD card up to 512 GB, back them up to a NAS, or use the encrypted HomeGuardian cloud service. This system integrates with Apple Home, Google Home, Alexa, SmartThings, and Home Assistant, making it a flexible choice for those building a comprehensive automated home.
