My Journey With Eufy’s Dual-Camera Doorbells
When I decided to upgrade my home security, Eufy’s dual-camera video doorbells caught my eye. The idea of one camera watching visitors and another keeping tabs on packages was a game-changer.
I’ve been using the S330 for over a year, and recently, I added the E340 to my setup to see how it stacks up. Both promise sharp video, smart alerts, and no mandatory subscriptions, but they’re not identical twins.
My experience with each revealed strengths, quirks, and a few surprises that might sway your decision.
Unpacking the Eufy S330: A Solid Performer With A Catch
The S330, also known as the Eufy Video Doorbell Dual, arrived with a sleek design and a HomeBase 2 hub in the box.
Setting it up felt like a small project—connect the hub to my router with an Ethernet cable, sync the doorbell, and mount it.
The process took about 30 minutes, including drilling holes for the mount.
If you’re not a fan of wiring, the rechargeable battery lasts up to six months, but I opted to hardwire it to keep it powered 24/7.
The dual cameras are the star of the show. The top 2K camera captures crisp, detailed footage of anyone at my door, while the 1080p bottom camera ensures I never miss a package. Daytime video is vibrant, with clear facial details even from 10 feet away.
At night, black-and-white night vision is sharp but lacks the pizzazz of color. Motion detection, powered by both PIR and radar sensors, is impressively accurate, rarely triggered by passing cars or swaying trees.
One feature I love is Delivery Guard. It alerts me when a package is dropped off and reminds me if I forget to grab it after a few hours. The facial recognition, tied to the HomeBase 2, tags familiar faces after some training, which is handy for spotting regulars like my mail carrier.
The Eufy Security app is intuitive, letting me tweak motion zones, video quality, and quick responses for visitors.
But it’s not perfect. The S330’s reliance on the HomeBase 2 is a double-edged sword. It enables local storage (16GB, about 60 days of clips) and advanced AI, but it’s an extra device cluttering my space.
The hub’s loud setup prompts drove me up the wall, and you can’t mute them until you’re fully configured. Also, the lack of Apple HomeKit or IFTTT support feels like a missed opportunity for smart home enthusiasts like me. And at roughly $260 with the hub, it’s a pricey investment.
Pros And Cons of The Eufy S330
Pros
- Crystal-clear 2K main camera for detailed visitor footage
- Dual motion sensors (PIR + radar) reduce false alerts
- Delivery Guard keeps packages safe with smart notifications
- Six-month battery life or wired option for flexibility
- Local storage via HomeBase 2, no subscription needed
- Facial recognition tags familiar faces accurately
Cons
- Requires HomeBase 2, adding setup complexity and cost
- No color night vision, only black-and-white
- Limited smart home integrations (no HomeKit or IFTTT)
- Bulky design may not suit narrow door frames
- Setup process can be noisy and tedious
Exploring The Eufy E340: A Standalone Star
The E340 feels like Eufy’s response to the S330’s shortcomings.
It’s slimmer, lighter, and doesn’t require a HomeBase, making it a breeze to install.
I had it up and running in 20 minutes, connecting directly to my Wi-Fi via the Eufy Security app.
Like the S330, it offers battery or wired power, but the battery is removable—a huge win if you want to swap in a spare without dismantling the doorbell.
The dual cameras are slightly different: a 2K top camera (2048×1536) and a 1600×1200 bottom camera. The resolution difference is subtle, but the E340’s color night vision steals the show.
Its dual-light system (spotlights and advanced processing) delivers vivid nighttime footage, making it easier to identify details like clothing colors after dark. I noticed this when a late-night delivery driver dropped off a package—the E340’s video was far clearer than the S330’s grayscale.
Motion detection relies on standard PIR sensors, which are solid but less precise than the S330’s dual setup. I got a few more false alerts from passing shadows, but tweaking the sensitivity helped.
The 8GB onboard storage holds about 30-90 days of clips, depending on activity, and you can pair it with a HomeBase 3 for up to 16TB of expandable storage. Delivery Guard and facial recognition are here too, though the latter needs retraining if you skip the HomeBase.
The E340’s price—around $160 standalone—makes it more accessible, and the lack of a mandatory hub keeps things simple.
However, the battery life is shorter (up to four months), and the absence of radar detection means it’s not as refined at filtering motion. Also, the speaker and microphone quality felt a tad weaker than the S330’s, making two-way audio slightly less clear.
Pros And Cons of The Eufy E340
Pros
- Color night vision for vibrant, detailed nighttime footage
- No HomeBase required, simplifying setup and reducing cost
- Removable battery for easy swaps without downtime
- 8GB onboard storage, expandable with optional HomeBase 3
- Slimmer, lighter design fits more door frames
- Affordable at ~$160 standalone
Cons
- Shorter battery life (up to 4 months)
- Standard PIR motion detection, less accurate than S330
- Slightly lower main camera resolution (2048×1536 vs. 2560×1920)
- Weaker speaker/mic quality for two-way audio
- No pre-roll feature, even when wired
Key Features of Eufy S330 And E340 Video Doorbells
Let’s break down the critical features that set these doorbells apart, based on my hands-on time with both.
- Video Quality and Cameras
Both doorbells rock dual cameras, but the S330 edges out slightly with its 2K (2560×1920) main camera versus the E340’s 2K (2048×1536).
In practice, the difference is negligible unless you’re zooming in heavily.
The S330’s 1080p package camera is outclassed by the E340’s 1600×1200, which captures sharper details of boxes or ground-level activity.
The E340’s color night vision is a clear winner, making nighttime footage feel like daytime, while the S330’s black-and-white vision feels dated.
- Motion Detection
The S330’s dual motion sensors (PIR + radar) are a cut above, catching human activity with precision and ignoring distractions like wind-blown leaves. The E340’s single PIR sensor is reliable but prone to occasional false triggers.
If you live on a busy street, the S330’s accuracy might save you from notification overload.
- Power and Battery Life
Both support battery or wired power, but the S330’s six-month battery life outlasts the E340’s four months. The E340’s removable battery is a lifesaver, letting you swap in a charged one in seconds.
When wired, both use a trickle-charge system, but the E340 still relies on its battery, which can be an issue in high-traffic areas or cold climates (below -20°C, charging slows).
- Storage and HomeBase
The S330 demands a HomeBase 2 (included), offering 16GB of local storage and cloud backup options.
The E340’s 8GB onboard storage is ample for most, and pairing it with a HomeBase 3 (sold separately) unlocks massive 16TB capacity and advanced AI like Cross Camera Tracking. The E340’s standalone capability is a big plus for minimalists.
- Smart Features and Integration
Both doorbells deliver Delivery Guard, facial recognition, and compatibility with Alexa and Google Assistant. The S330’s AI feels slightly more polished, thanks to the HomeBase 2’s processing power, but the E340 holds its own.
Neither supports Apple HomeKit or IFTTT, which is a bummer for iOS-heavy households. The E340’s dual-light system adds a practical touch, illuminating your doorstep when motion is detected.
- Design and Installation
The E340 is slimmer (6.0 x 2.0 x 1.1 inches) and lighter (0.49 lbs) than the S330 (6.3 x 2.1 x 1.1 inches, 0.55 lbs), making it easier to fit on narrow frames. The E340’s setup is quicker, skipping the hub, while the S330’s HomeBase adds a step.
Both include mounts and wedges for angled views, but neither offers renter-friendly options like adhesive mounts.
- Price and Value
At $260 with a HomeBase 2, the S330 is a premium pick, justified by its longer battery life and superior motion detection. The E340, at $160 standalone, is a better deal for budget-conscious buyers or those who don’t need a hub.
If you already own a HomeBase 3, the E340’s compatibility makes it even more appealing.
My Experience With Eufy S330 And E340 Video Doorbells
To give you a sense of how these doorbells perform day-to-day, let me share a few scenarios from my testing.
One busy Saturday, I had multiple deliveries.
The S330’s Delivery Guard pinged me instantly| immediately when a package landed, and the facial recognition tagged my regular UPS driver, making it easy to confirm who dropped it off.
The E340 also caught the delivery but missed a second package left slightly out of frame, likely due to its narrower field of view.
At night, the E340’s color vision helped me spot a stray cat rummaging through a bag, while the S330’s grayscale footage left me squinting.
During a windy storm, the S330 ignored most gusts, but the E340 triggered a few false alerts from swaying branches. Hardwiring the E340 kept it running smoothly, but I noticed the battery still drained slightly over a month, confirming it leans on the battery even when wired.
Swapping the E340’s battery was a cinch, taking under a minute, while the S330 required me to unmount it for charging, which was a hassle.
The Eufy Security app was a consistent highlight. Viewing clips, adjusting settings, and setting up motion zones was straightforward on both devices.
However, the S330’s hub occasionally lagged when streaming to my Google Nest Hub, while the E340’s direct Wi-Fi connection felt snappier.
Which Doorbell Should You Choose?
Your decision hinges on your priorities. If you want top-tier motion detection, longer battery life, and don’t mind the HomeBase 2, the S330 is your pick. Its dual sensors and robust AI make it ideal for busy households or areas with lots of foot traffic.
However, if you value simplicity, color night vision, and a lower price, the E340 is a no-brainer. It’s perfect for renters, small homes, or anyone who wants a plug-and-play solution without extra hardware.
I lean toward the E340 for its ease of use and vibrant nighttime footage. The removable battery and standalone design fit my low-maintenance vibe, and the price is easier to swallow.
But if you’re building a full Eufy ecosystem with a HomeBase 3, the S330’s deeper integration might tip the scales.
