I went into this lock showdown thinking I already knew which one I’d prefer. Ultra Wideband (UWB) sounded cool, but I assumed facial recognition would be the “real” futuristic option and win in day-to-day convenience. Then I actually lived with both—Aqara’s U400 and the Lockly Visage—side by side, and yeah… I was wrong. In this video I break down what matters when you’re not just doing a demo unlock for the camera: reliability, speed, and how often the lock makes you do “the thing” again because it didn’t catch you the first time. I compare UWB proximity unlock versus face unlock and talk through the practical stuff—how it feels walking up with full hands, how consistent it is across different conditions, and which one I’d trust as my primary way to get in the door. If you’re trying to decide between the Aqara U400 and the Lockly Visage, this is less about hype and more about what actually works when you’re just trying to get inside.
