In this video I unbox and fully review the Aqara G400 Video Doorbell and walk you through exactly what you need to know before you install it. I cover setup and installation, price and specs, and then I spend time in the Aqara app so you can see how the day-to-day experience actually works. I also do a two‑way audio / speaker test, because on a doorbell that’s one of those “looks good on paper” features that can make or break the real-world experience. After that, I show how the G400 behaves inside Apple Home, including HomeKit Secure Video support, and I talk through what I like and what I don’t. My big takeaway is that Aqara is clearly aiming this at the smart home crowd that wants broad compatibility and a modern feature set without turning their front door into a science project. I wrap it up with my pros and cons and my final thoughts so you can decide if the G400 is the kind of doorbell you’ll actually want to live with in 2026.
