Our take
The S330 bundles a fingerprint deadbolt, a 2K camera, and a doorbell into one unit with a big rechargeable battery and local SD/onboard storage, so you can skip a separate video doorbell. It's a lot of value, but it's chunky, ties you into the eufy app, and the all-in-one design means a failure takes out lock and camera together.
What we like
- Combines smart lock, 2K camera, and video doorbell in one device
- Local onboard storage with no mandatory subscription
- Fast fingerprint unlock plus keypad and app options
- Large rechargeable battery rather than disposable cells
What to keep in mind
- Large, conspicuous unit that dominates the door
- Locks you into the eufy app and ecosystem
- One combined device means a fault can disable lock and camera at once
