The Eufy S330 Video Doorbell is a solid piece of hardware let down by a company that got caught lying to its customers. If you can live with that context – and some people reasonably can – it remains one of the better no-subscription doorbells on the market. If you cannot live with it, the newer S4 fixes some things but shares the same parent company. Your call.

Video Quality
This is where the S330 earns its keep. The front-facing 2K HDR camera is noticeably better than the 1080p units that were standard when the original version of this review was written. You get real detail – enough to read a license plate, identify a face, see what a package delivery person actually did with your parcel.
The second downward-facing camera is a genuinely useful addition that competitors have been slow to copy. Packages do not vanish into a blind spot at your feet. Night vision is competent – not breathtaking, but you will know who is standing at your door at 2am.
HDR handles backlit situations (bright sky, shaded doorway) better than a single-exposure camera. It matters more than the spec sheet makes it sound.
HomeKit / Smart Home Integration
Let’s correct something the original version of this review got wrong: the S330 does not support Apple HomeKit. It works with Alexa and Google Assistant, full stop. HomeKit is not on the table.
If HomeKit is your thing, you have a few options. Third-party bridges like Homebridge can proxy Eufy devices into the Apple Home ecosystem, but that requires running additional hardware and has historically been unreliable with Eufy’s app updates. Eufy’s newer S4 doorbell (announced for 2026) is supposed to support Apple Home natively – but that is a different product at a likely higher price point.
For more on whether Eufy works with HomeKit in general, we covered the full picture there. Short version: some Eufy cameras do, the S330 doorbell does not.
Local vs Cloud Storage (No Subscription)
The no-subscription angle is still real and still works. The HomeBase 2 hub has 16GB of built-in storage – enough for roughly 180 days of event-triggered clips. You can expand that by plugging in an external drive. Live streaming, motion alerts, AI detection, and all the recording functionality work without paying Eufy a dollar per month.
Eufy does offer optional cloud backup if you want off-site copies, but it is genuinely optional rather than a required unlock. This is a meaningful difference from Ring and Nest, both of which significantly cripple their free tiers.
One real downside with the battery version: if somebody steals the doorbell, the footage is stored on the HomeBase inside your house, so it is not lost with the hardware. That is actually better than a microSD-in-the-doorbell setup, though it does mean setting up the HomeBase during installation.
The Privacy Elephant in the Room
In late 2022, Eufy (owned by Anker) was caught doing exactly what it promised not to do. Security researchers found the cameras were uploading facial recognition data and live footage thumbnails to Eufy’s cloud servers – without encryption, without user knowledge, and despite the company’s explicit marketing claims about local-only storage.
It got worse from there. Unencrypted live streams were accessible to anyone with the right URL, no authentication required. Anker initially denied the problem, gave evasive non-answers for weeks, and only admitted the full scope after The Verge threatened to publish their findings. A class action lawsuit followed in early 2023.
Anker has since pushed firmware updates and made security commitments. Whether those commitments hold is not something you can verify from the outside – which is the point. The company demonstrated it was willing to lie about this specific feature to sell product. That is not a minor firmware bug; it is a trust problem.
Whether that disqualifies the S330 for you depends on your threat model. If you are putting a camera on your front door and are relaxed about the data implications, the hardware quality may still win the argument. If you have strong privacy requirements, Eufy is not the brand for you right now.
Who Should Buy the S330
Buy it if: you want 2K dual-camera doorbell quality without a monthly subscription, you use Alexa or Google Home, and the 2022 privacy mess does not alter your buying decision.
Skip it if: you need HomeKit support (it does not work), privacy is a hard requirement, or you want the latest hardware (the S4 is the current-gen Eufy doorbell for 2026).
The S330 sits in an odd position in 2026 – it is not the newest Eufy doorbell, but it is still sold, still performs well on video quality, and the no-subscription model is intact. At the right price it is a reasonable buy. Just go in knowing what you are actually getting.
