What the differences mean

Camera against entry methods

The Eufy Video Smart Lock S330 packs a 2K camera and doorbell with local recording. The Aqara Smart Lock U100 has no lens but offers more ways to get in, including Apple Home Key and NFC tags.

Hub or no hub

The Aqara Smart Lock U100 needs an Aqara hub for remote access and for Alexa, Google or Matter, and works over Bluetooth otherwise. The Eufy Video Smart Lock S330 has built-in Wi-Fi, so remote control works with no hub.

Ecosystem

The Aqara Smart Lock U100 supports Apple HomeKit natively and Home Assistant. The Eufy Video Smart Lock S330 works with Alexa, Google Home and Home Assistant but not HomeKit or Matter. For an Apple home the Aqara is the natural pick.

Battery

The Aqara Smart Lock U100 runs around eight months on four AA batteries, while the Eufy Video Smart Lock S330, with its camera and doorbell, needs a charge every few weeks to months on its built-in pack.

Video storage

The Eufy Video Smart Lock S330 records video locally to a microSD card or a HomeBase, with no subscription. The Aqara Smart Lock U100 stores no video, because it has no camera.

Shared ground

Both are IP65 rated and both carry a one-year warranty, so weather sealing and warranty do not separate these two.

Which one to buy if

What owners say

Owners of both locks like having several ways in, and both groups report a fast, accurate fingerprint reader. Aqara Smart Lock U100 owners single out Apple Home Key, the NFC and keypad options, and native HomeKit and Home Assistant support, and they warn that remote access and Alexa, Google or Matter need an Aqara hub and that build quality is hit or miss. Eufy Video Smart Lock S330 owners love the built-in 2K camera and the subscription-free local recording, with every entry logged on video, but they flag that motion detection misses people and deliveries, that a minority saw the lock fail or a firmware update break features, and that the single battery needs frequent charging.

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.
