About This Video

In this video I unbox and review the Aqara U400 UWB smart lock and dig into why Ultra Wide Band is a big deal for a front door. I walk through what’s in the box, how the lock is built, and what the setup and installation process looks like in the real world—not just the marketing version. I also cover pricing, specs, and the Aqara app highlights so you can see what you’re actually getting day-to-day. The headline feature here is precise location recognition with UWB, and I talk about how that changes the “walk up and unlock” experience compared to typical Bluetooth or geofencing setups. I also show how the U400 integrates with Apple Home/HomeKit, since that’s a huge part of how I personally run smart home security. I finish with my pros, the one big con that stood out to me, and who I think this lock makes sense for if you’re trying to protect what matters most without making your entryway complicated.
