2026 verdict
A plain fingerprint deadbolt against a lock that is also a camera, and the Eufy Security Smart Lock S230 takes the win on the fundamentals.
It is the more affordable, better rated and longer warranted of the two, with an IP65 body and a rechargeable battery rated near a year, and its built-in Wi-Fi needs no hub. The Eufy Video Smart Lock E330 brings the one thing the S230 cannot: a 2K camera and doorbell that record locally to 8GB with no subscription, plus Apple Home Key and Home Assistant support. Neither offers HomeKit or Matter, and both use built-in Wi-Fi. Pick the Eufy Security Smart Lock S230 for dependable keyless entry, and the Eufy Video Smart Lock E330 when a built-in camera is the point.

What the differences mean
Camera and doorbell
The Eufy Video Smart Lock E330 adds a 2K camera, night vision and a doorbell that record to 8GB of built-in storage with no subscription. The Eufy Security Smart Lock S230 has no lens at all, so it is only a lock.
Power and weather
The Eufy Security Smart Lock S230 runs on a rechargeable battery rated near a year and is IP65 rated, while the Eufy Video Smart Lock E330 lasts about eight months and is IP53, so it wants a sheltered door.
Open-door sensor
The Eufy Video Smart Lock E330 has no open-door sensor, so its auto-lock works on a timer and can extend the deadbolt while the door is open. The Eufy Security Smart Lock S230 is a simpler lock without that camera-driven behavior.
Warranty
The Eufy Security Smart Lock S230 carries an 18-month warranty against the one year of the Eufy Video Smart Lock E330.
Integrations
The Eufy Video Smart Lock E330 supports Apple Home Key and Home Assistant on top of Alexa and Google Home. The Eufy Security Smart Lock S230 sticks to Alexa and Google Home. Neither supports HomeKit or Matter.
Which one to buy if
- you want keyless entry and nothing more
The Eufy Security Smart Lock S230 is the simpler, cheaper deadbolt with a longer battery and a tougher weather rating.
- you want a camera and doorbell in the lock itself
The Eufy Video Smart Lock E330 is the only one of the two with a 2K camera and local, subscription-free recording.
- your door is exposed to rain
The Eufy Security Smart Lock S230 is IP65 rated, while the Eufy Video Smart Lock E330 is only IP53.
- you rely on Home Assistant or Apple Home Key
The Eufy Video Smart Lock E330 adds both, while the Eufy Security Smart Lock S230 does not support them.

What owners say
Owners of both eufy locks agree on the fingerprint reader: it is fast and reliable, even with damp hands, and both install easily on a standard deadbolt with no hub needed. Eufy Security Smart Lock S230 owners single out the IP65 body, the rechargeable battery rated near a year and the simple one-app setup, and they warn that Wi-Fi can drop and that a minority saw units fail around the two-year mark. Eufy Video Smart Lock E330 owners love getting a 2K camera and doorbell that record locally with no fee, and their caveats are that there is no open-door sensor so auto-lock can fire with the door open, that motion detection misses people without tuning, and that the battery can need charging every few months.
