It records 5MP over a 166 degree view with colour night vision, joins 2.4 and 5 GHz Wi-Fi, lets you draw motion zones and keeps 60 days of loop recording on an included base that doubles as the chime. The Aqara Smart Video Doorbell G4 is the lower priced one and answers with HomeKit Secure Video, Home Assistant support, free local face recognition, a microSD slot in its chime and seven days of free cloud, but it records 1080p with black and white night vision on 2.4 GHz only.
