The Aqara G410 Doorbell Camera Hub consists of an outdoor doorbell and an indoor chime. The doorbell activates via radar, which effectively reduces the false activation issue caused by traditional PIR in outdoor environments. The doorbell lens has been upgraded to a 175° ultra-wide-angle field of view, the image sensor aspect ratio is 4:3, and the vertical field of view is improved. The camera features an upgraded 3MP resolution for sharper video clarity, complemented by ten 940nm non-intrusive infrared lights to significantly enhance night vision performance. The doorbell has a built-in face recognition algorithm running locally (within the doorbell itself) which can mark and identify the identity of visitors. The indoor chime is also a Zigbee/Thread dual-protocol hub, which can connect to other Aqara smart devices. The wireless connection between the chime and the outdoor doorbell is 10 metres, allowing for versatile placement in the home.
