The one thing most doorbell cameras miss is the package sitting right below them on your doorstep, and the video doorbell s330 from eufy was built specifically to fix that blind spot. By stacking a second downward-facing camera beneath the main lens, the video doorbell s330 watches both your visitor’s face and the ground where deliveries land, then stores the footage locally with no subscription attached. For homeowners tired of paying a monthly fee just to review a clip, that combination is the headline feature.

The Dual-Camera Design
Traditional doorbell cameras use a single wide lens angled to catch a person standing at the door. That works for faces, but a box left near your feet often falls outside the frame or is badly distorted at the edge. The S330 solves this with two separate cameras: a 2K forward camera for people and a dedicated package-detection camera aimed downward at the porch.
When a delivery arrives, the lower camera can identify a left package and send you a specific “package detected” alert rather than a generic motion notification. The same view tells you the moment a box disappears, which is exactly the footage you want if a porch theft happens.
2K Video Quality
Resolution is where cheap doorbells fall apart, especially at night or when you need to read a face across the yard. The S330 records at 2K, noticeably sharper than the 1080p standard on budget models, so you can actually make out license plates at the curb, a delivery driver’s uniform, or the features of an unfamiliar visitor.
Beyond raw resolution, it includes HDR to balance harsh backlight, useful when someone stands in front of a bright afternoon sky, and infrared night vision for after-dark clarity. A wide vertical field of view keeps a tall visitor’s head and the doormat in the same shot.
Local Storage and No Monthly Fee
This is the S330’s biggest selling point against Ring and Nest. Instead of pushing every clip to a cloud service that charges a recurring fee, footage records to a HomeBase hub included with the wired kit. The HomeBase stores video on local memory, so your recordings live in your house, not on a subscription server.
- No monthly fee — the storage you buy once is the storage you keep.
- Local encryption — video is stored on the HomeBase rather than a third-party cloud, which many privacy-minded owners prefer.
- Expandable capacity — the base holds ample recording time, often weeks of events, before older clips roll off.
Over three years, skipping a $3 to $10 monthly cloud plan saves roughly $100 to $360, which more than covers the price difference against a subscription-locked competitor. If you later want an off-site backup for peace of mind, eufy does offer an optional cloud tier, but it is a choice rather than a requirement baked into the hardware you already own.
Wired Installation
The S330 is a wired doorbell that connects to your existing doorbell transformer, typically 16 to 24 volts AC, the same wiring most homes already have behind the old chime button. Because it draws continuous power, you never juggle batteries or worry about a dead unit missing an event.
Installation is a manageable DIY job for most homeowners:
- Turn off power to the doorbell circuit at the breaker.
- Remove the old doorbell button and note the two low-voltage wires.
- Mount the S330 bracket, using the included wedge if you need to angle the view along a porch.
- Connect the two wires to the terminals and seat the doorbell on the bracket.
- Restore power, plug in the HomeBase indoors, and follow the eufy Security app to pair the devices to Wi-Fi.
Plan on 30 to 45 minutes. If you have no existing doorbell wiring, you will need a transformer and possibly an electrician, so factor that in before you buy.
Smart Features and App Control
The eufy Security app ties everything together. You get real-time alerts, two-way talk so you can tell a driver where to leave a box, and adjustable motion zones that cut down on false alerts from passing cars or a busy sidewalk. On-device AI distinguishes people from general motion, which keeps your phone from buzzing every time a leaf blows past.
It also works with Amazon Alexa and Google Assistant, so a compatible smart display can pop up the live feed when someone rings. Response time from ring to notification is quick on a solid Wi-Fi connection, which matters when you have only a few seconds to catch a visitor before they walk off.
Price and Value
The wired S330 kit, doorbell plus HomeBase, typically sells for around $150 to $180, and it frequently drops during major sale events. That is a bit more upfront than a bargain single-camera doorbell, but the math flips fast once you factor in the absence of a recurring fee and the second camera you would not get at any price on most competitors.
For a homeowner who receives regular deliveries and does not want another subscription, the value case is strong.
How It Handles Motion and Alerts
False alerts are the fastest way to make anyone ignore a doorbell camera. The S330 leans on on-device AI to sort human motion from everything else, so a car rolling down the street or a cat crossing the yard does not necessarily light up your phone. You draw activity zones in the app, boxing in your walkway and porch while excluding the sidewalk and the neighbor’s driveway, and the camera only reports movement inside those lines.
Sensitivity is adjustable in steps, which matters more than it sounds. A porch that faces a busy street needs tighter zones and lower sensitivity than a quiet cul-de-sac. Spend ten minutes tuning these settings during setup and you will get alerts that mean something instead of a phone that buzzes forty times a day.
Battery vs. Wired Considerations
eufy offers this doorbell in both wired and battery-oriented configurations across its lineup, but the S330 is fundamentally a wired unit that leans on your existing 16 to 24-volt AC doorbell transformer. That constant power is a genuine advantage: the cameras stay fully awake, recording begins the instant motion starts, and you never lose coverage waiting for a battery-powered camera to spin up.
The downside is placement. If your front door has no existing doorbell wiring, you either add a transformer, which is a modest electrical job, or you look at a battery model instead. Before you buy, pull the old doorbell button off the wall and confirm you see two low-voltage wires; that thirty-second check tells you whether install will be a breeze or a bigger project.
Pros and Cons
No doorbell is perfect, so weigh these before committing:
- Pros: dual cameras with true package detection, sharp 2K video, local storage with no monthly fee, reliable wired power, and easy DIY install on existing doorbell wiring.
- Cons: requires existing doorbell wiring or a transformer, the HomeBase must stay connected indoors, and the eufy ecosystem is less universal than Ring or Nest if you already own those devices.
Who It Is Best For
The S330 is a natural fit for suburban homeowners who get frequent deliveries and want proof of what lands on the porch and what leaves it. It also suits anyone philosophically opposed to renting access to their own footage; the local-storage model appeals strongly to privacy-conscious buyers. Renters with existing doorbell wiring can use it too, since it removes cleanly and the recordings travel with you.
If your priority is watching both your visitors and your deliveries without feeding a subscription every month, the video doorbell s330 is one of the smartest picks on the market right now. Homeowners deep in the Ring or Google ecosystem may stick with what they have, but everyone else gets a genuinely better answer to the porch-piracy problem for a one-time price.
