The Aqara Doorbell Camera Hub G410 serves as both a high-resolution security entrance and a central command center for your smart home. It captures video in 2K resolution and uses a combination of an on-device facial recognition system and a mmWave radar presence sensor to accurately detect who is at your door. To keep your home connected, the device functions as a Matter controller, Zigbee hub, and Thread border router, supporting connectivity via dual-band Wi-Fi, Bluetooth, and IEEE 802.15.4 standards. Designed for flexibility, the doorbell can be powered by 12V-24V AC/DC wiring or run wirelessly using six replaceable AA alkaline batteries, which can last up to five months. The main unit is built to withstand temperatures from -18°C to +50°C, while the accompanying chime repeater handles indoor alerts with an adjustable 95 dB speaker. For storage, you can use a microSD card up to 512 GB, a NAS backup, or an encrypted HomeGuardian cloud subscription. This system integrates with Apple Home, Google Home, Alexa, SmartThings, and Home Assistant, allowing you to set up automated greetings or link the doorbell to your smart locks. You can communicate with visitors through two-way audio with voice modification for added privacy. The package includes the doorbell, chime repeater, a 20° wedge bracket for better angling, and all necessary mounting hardware to get your system installed.
