The Aqara Smart Lock U200 takes this smart lock matchup on price, weather resistance and the widest set of platforms and ways in, from a fingerprint and passcode to NFC and Apple Home Key over Matter and Thread. It also keeps your existing exterior key, since it only replaces the inside of the deadbolt, and reaches Apple HomeKit, SmartThings and Matter, none of which the Eufy Video Smart Lock E330 supports. That Eufy answers with a higher owner rating, a longer battery and the one thing the Aqara cannot do: a built-in 2K camera and video doorbell that records locally with no subscription. Choose the Aqara Smart Lock U200 for compatibility and keyless breadth without video, and the Eufy Video Smart Lock E330 if you want the doorbell and camera built into the lock.

What the differences mean

Camera and doorbell

The Eufy Video Smart Lock E330 builds in a 2K camera, night vision, motion detection and a doorbell with 8GB of local storage and no subscription. The Aqara Smart Lock U200 has no camera at all, so if you want to see who is at the door you need a separate doorbell.

How it installs

The Aqara Smart Lock U200 is a retrofit that replaces only the interior of the deadbolt and keeps your exterior key cylinder. The Eufy Video Smart Lock E330 replaces the whole deadbolt, with an upgradeable key cylinder, so plan the swap accordingly.

Ways in

The Aqara Smart Lock U200 adds NFC and Apple Home Key on top of fingerprint, passcode, app, Bluetooth and a physical key. The Eufy Video Smart Lock E330 covers fingerprint, passcode, app and a physical key, but it has no NFC and no Apple Home Key.

Ecosystem support

The Aqara Smart Lock U200 reaches Apple HomeKit, Google Home, Alexa, SmartThings, Home Assistant and Matter over Thread. The Eufy Video Smart Lock E330 is limited to Alexa, Google Home and Home Assistant, with no HomeKit, SmartThings or Matter.

Weather and battery

The Aqara Smart Lock U200 is IPX5 and rates its battery at about six months. The Eufy Video Smart Lock E330 is IP53, a lighter splash rating, but rates its battery at about eight months, and its camera work drains it faster than the figure suggests.

What owners say

The two attract different buyers, and the reviews show it. Owners of the Aqara Smart Lock U200 rave about how much it does when it works: Apple Home Key unlocking from a watch, a fast fingerprint reader, and support for more ecosystems than almost any rival, all on a retrofit body that keeps their key. Their warnings are serious, though, with a notable group reporting the lock grinding or turning intermittent after a year, difficult calibration, and a clunky app that needs a Thread hub ready. Eufy Video Smart Lock E330 owners praise the fingerprint that reads every time even in rain, the sharp 2K camera and doorbell, the local storage with no fee and eufy's support; their complaints are missed motion, battery that lasts months not the advertised figure, and the absent door sensor that lets auto-lock extend with the door open.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.

Frequently Asked Questions

Which is better overall: Aqara Smart Lock U200 or Eufy Video Smart Lock E330?

The Aqara Smart Lock U200 wins on price, weather resistance and the widest platform and unlock-method support, including NFC and Apple Home Key. The Eufy Video Smart Lock E330 rates higher with owners and is the only one of the two with a built-in 2K camera and doorbell, recording locally with no subscription.

What is the biggest difference between the Aqara Smart Lock U200 and the Eufy Video Smart Lock E330?

The Aqara Smart Lock U200 is a retrofit deadbolt that keeps your existing key and connects to nearly every platform over Matter and Thread, with no camera. The Eufy Video Smart Lock E330 is a full deadbolt with a fingerprint reader and a built-in 2K camera and doorbell, but a narrower set of integrations.

Which of the two locks works with Apple HomeKit or Matter?

The Aqara Smart Lock U200 supports Apple HomeKit (with Apple Home Key), Matter over Thread, SmartThings and Home Assistant. The Eufy Video Smart Lock E330 supports only Alexa, Google Home and Home Assistant, with no HomeKit, SmartThings or Matter.

Does the Aqara Smart Lock U200 have a camera or doorbell?

No. The Aqara Smart Lock U200 has no camera, night vision or doorbell, so it cannot show you who is at the door. The Eufy Video Smart Lock E330 is the one that builds a 2K camera, motion detection and a doorbell into the lock.

Do the Aqara Smart Lock U200 and the Eufy Video Smart Lock E330 need a hub?

The Aqara Smart Lock U200 needs a Thread border router for remote access and full features, and falls back to Bluetooth at the door without one. The Eufy Video Smart Lock E330 connects over its own 2.4GHz Wi-Fi, so it does not need a separate hub for remote control.

Who should buy the Eufy Video Smart Lock E330?

Buyers who want a fingerprint deadbolt with a built-in 2K doorbell and camera and subscription-free local recording, and who accept a narrower set of smart home integrations and an auto-lock that lacks a door-open sensor.
