Eufy Video Doorbell (Wired) S330 Review: A Dual-Camera Doorbell That Watches Your Packages Without a Subscription
The Eufy Video Doorbell (Wired) S330 is for homes with existing doorbell wiring that want to see packages as well as visitors. Its front camera records in 2K with HDR and a second low-angle camera keeps the doorstep in view, while events are stored on 8GB of built-in memory and playback needs no subscription. It works with Alexa and Google, but only over 2.4GHz Wi-Fi, it is hardwired only, and most older transformers must be upgraded to 16-24VAC at 30VA or more before it will run reliably.

- Some owners report Wi-Fi dropouts or failure after a year or two
Who is the Eufy Video Doorbell (Wired) S330 for?
It suits a house that already has doorbell wiring and wants a doorbell that never needs charging. Because it runs on your existing 16-24VAC supply, it stays awake day and night and can start recording the moment motion is detected, unlike battery doorbells that sleep to save power. The dual cameras are its draw: a 2K front camera with HDR for the visitor and a second low-angle camera aimed at the ground so a parcel left at the door stays in frame. It pairs with Alexa and Google for voice control and live view, and it works with Home Assistant through the community eufy Security integration. It is not for renters or anyone without wiring, since it has no battery mode, and it is not an Apple Home or Matter device.
What owners praise
Owners consistently call it easy to install when the wiring and a strong enough transformer are already in place, and they like that the app walks them through setup. The dual-camera view is the feature they single out most: seeing the spot where packages are dropped, not just the person at the door. Buyers also value that recording and playback need no subscription, with events stored on the doorbell itself, and they describe the 2K picture as sharp and the infrared night vision as clear. Human and familiar-face alerts are reported as accurate, activity zones and pre-recorded quick responses are popular, and the smart lock, camera and sensor sharing inside the eufy app gets repeat mentions. Several owners moved over from Ring, Arlo or Blink specifically to drop a monthly plan.
What to know before you buy
The transformer is the catch that comes up again and again: a typical older 16V 10VA supply is not enough, and owners had to fit a 16-24VAC 30VA or higher replacement, often a 24VAC 40VA unit for a modest price, before the doorbell would stay online. It is hardwired only and 2.4GHz Wi-Fi only, and pairing can be fiddly on a dual-band router, where a 2.4GHz network may be needed. The doorbell comes with its own plug-in chime, but your existing mechanical chime has to be bypassed with the supplied jumper. Reliability is mixed: many units run for years, while some owners report the doorbell dropping off Wi-Fi or failing after a year or two, though eufy support replaced several of those. Motion and package detection can be over-sensitive, so plants, cars or a doormat may trigger alerts until the sensitivity and zones are tuned, and the app is busy with promotions for other eufy gear. There is no microSD slot, no HomeKit and no Matter, and it records events rather than 24/7 video.
Is the Eufy Video Doorbell (Wired) S330 worth it?
For a wired home that wants package coverage and no monthly fee, it is a strong pick: dual 2K cameras, 8GB of local storage, Alexa and Google support, and a clear app, at a price well below most subscription-based rivals. Budget for a new transformer, and accept 2.4GHz-only Wi-Fi, no microSD, no HomeKit or Matter, and event recording instead of continuous capture. With those caveats it is one of the better value wired doorbells, and the dual-camera view is the reason to choose it over a single-lens model.
Frequently asked questions
Does the Eufy Video Doorbell (Wired) S330 need a subscription?
No. Events are stored on 8GB of built-in memory and playback is free, with cloud backup optional if you want a second copy. There is no microSD slot.
Does it work with Alexa and Google Home?
Yes. It works with Amazon Alexa and Google Assistant for voice control and live view on their displays, and an Amazon Echo can act as a chime. It does not support Apple HomeKit or Matter.
What transformer does the S330 need?
It runs on existing doorbell wiring at 16-24VAC with a transformer rated 30VA or higher. An older 16V 10VA transformer is usually too weak and causes the doorbell to drop offline, so many owners upgrade to a 24VAC 40VA unit.
Can it record 24/7?
No. It records motion-triggered events, not continuous video, and stores them on the built-in 8GB memory until the oldest events are overwritten.
Does it ring the chime in my house?
A doorbell chime is included in the box. The doorbell can also ring an existing mechanical chime over the wiring, but that chime usually has to be bypassed with the supplied jumper, and an Amazon Echo can be used as an extra chime.
Does it work with Home Assistant?
Yes, through the community eufy Security integration, which lists the wired S330 by its model code T8203.
