We tested the top integrated smart locks that combine a lock, camera, and doorbell in one device. Our pick: the Eufy S330 Video Smart Lock delivers 2K video, local storage, and no monthly fees. Also reviewed: Lockly Vision Elite (with solar charging) and Lockly Vision (budget entry).
The front door is the busiest intersection in any home. Packages land, guests arrive, and you still need to know who's knocking — without juggling three separate gadgets. A smart lock with a built-in camera collapses the usual tangle of doorbell cam + deadbolt + bridge into a single, streamlined device. Less clutter, fewer batteries to swap, and one app to rule them all.
We've tested the leading integrated units against the gold standard of separate combos (think Ring Video Doorbell paired with a Schlage Encode). Here are the things actually worth buying.
The Eufy S330 is the rare product that earns its "3-in-1" badge honestly: it's a smart lock, a video doorbell, and a security camera fused into one unit.1 The 2K camera captures crisp, detailed footage of visitors and package deliveries, and everything records directly to local SD storage — no cloud subscription, no monthly fee.1
Battery life is strong thanks to a large rechargeable pack, and the lock mechanism itself is responsive via both the Eufy app and physical key backup. If you want one device that does it all without asking for a recurring payment, this is it.
Who it's for: Anyone who wants the best video quality, local-only storage, and a single-device solution.
Lockly's Vision Elite takes a different approach: a 1080p Full HD camera paired with a small solar panel built into the lock's faceplate.2 That panel trickle-charges the battery, meaning you'll recharge far less often than any competitor. It also features Lockly's randomized PIN keypad — digits shuffle positions on each use so shoulder-surfers can't steal your code.2
The trade-off? 1080p video instead of 2K, and the solar panel works best on doors that get direct sun for part of the day. Still, for a premium lock that practically maintains itself, the Elite is a standout.
Who it's for: Homeowners with a sun-facing door who want minimal battery maintenance and top-tier keypad security.
The standard Lockly Vision shares the same randomized keypad and 1080p camera as the Elite, but drops the solar panel and uses AA batteries instead of a rechargeable pack.3 It's a capable integrated lock at a lower price point, though you'll want to keep spare AAs on hand.
One notable omission: the base Vision lacks motion-triggered recording, so it only captures video when someone rings the bell or you manually trigger it. If that's acceptable, it's a solid way into the category without spending top dollar.
Who it's for: Budget-conscious buyers who want an integrated lock-camera and don't need motion-activated recording.

Integrated smart locks trade one thing: flexibility. A separate combo like Ring + Schlage lets you mix ecosystems — maybe you want a Ring doorbell for Amazon delivery integration but a Schlage lock for Z-Wave home automation. With an integrated unit, you're locked into one brand's app and ecosystem.
That said, for most people the convenience of a single device outweighs the flexibility of a split setup. You get one installation, one app, one set of batteries to manage. The three picks above represent the best of this integrated approach at three different price and feature tiers.
Local vs. cloud storage. The Eufy S330's local SD storage means zero monthly fees and no dependency on a company's servers. Cloud-dependent locks may charge subscriptions for video history.
Battery life and power. Rechargeable batteries (Eufy S330) are cheaper long-term than AAs (Lockly Vision). Solar assist (Vision Elite) is a bonus if your door gets direct light.
Physical key backup. Every lock on this list includes a traditional keyway. Don't buy a smart lock that omits this — if the electronics fail or the battery dies, you still need to get inside.
Video quality. 2K (Eufy) captures license plates and package details that 1080p (Lockly) might miss. For most doorsteps, 1080p is adequate; for high-traffic entries, 2K is worth the premium.
