In this video I’m testing what might be the most “future-looking” retrofit smart lock I’ve put on a door: the SwitchBot Lock Ultra paired with the Keypad Vision. The wild part is the 3D facial recognition—on a retrofit lock—so you’re not replacing the whole deadbolt like a lot of other setups. I walk through the unboxing, the install, and the day-to-day experience of actually using face unlock at the front door, plus the usual stuff people care about like backup entry methods and how practical it is for a real household. I also unbox and demo the SwitchBot Hub 3, because it’s clearly meant to be the command center that ties the whole thing together. I go over the specs, show you what the SwitchBot app experience looks like, and then I give you my honest pros and cons after using it. If you’re into Apple Home/HomeKit, Matter, and building a smart home that’s convenient without being sloppy on security, this one is absolutely worth a look—because facial recognition on a lock is either a gimmick or a game-changer, and I break down where it lands for me.
