Eufy Video Doorbell E340 Review
Dual-Lens Precision and Zero Monthly Fees: Is This the Ultimate Package Protector?
In the world of smart home security, "subscription fatigue" is a real problem. Most brands lure you in with a sleek device, only to lock your video history behind a monthly paywall. The Eufy Video Doorbell E340 is the industry's boldest answer to this trend. By offering professional-grade dual-camera technology combined with robust local storage, Eufy has created a "buy it once, own it forever" security solution.
We recently ranked this model as a top contender in our curated list of the best video doorbells for package security. In this deep-dive review, we’ll explore why having two lenses is better than one and how Eufy’s AI stands up against the giants like Ring and Nest.
👁️ 1. Why Two Lenses? Solving the "Blind Spot" Problem
Most video doorbells suffer from a fatal flaw: a limited vertical field of view. While they can see the face of the person standing at the door, they are "blind" to the ground. This is exactly where delivery drivers leave packages, and where "porch pirates" strike.
The Eufy E340 solves this with a dual-lens array:
- Primary Camera: A 2K Ultra-HD lens that captures facial details with incredible clarity, even in backlit conditions.
- Secondary Camera: A 1080p lens tilted downward at a specific angle to monitor the porch floor.
Eufy’s software seamlessly stitches these two images together. When you open the app, you see a comprehensive view of your entryway. This technology is a significant reason why the E340 is consistently featured in any serious review of the best smart doorbells available today.
💰 2. The Death of Monthly Subscriptions
Perhaps the most compelling reason to choose Eufy is the financial aspect. While other brands charge between $60 and $120 per year just to save your footage, the E340 comes with 8GB of built-in storage. This is enough to store approximately 60 to 90 days of video clips based on average motion events.
If you want even more power, you can pair the E340 with the Eufy HomeBase 3. This bridge adds advanced "BionicMind" AI (which can recognize specific family members) and allows you to expand the storage up to a staggering 16TB using an off-the-shelf hard drive. For a one-time investment, you get a system that outlasts and outperforms cloud-dependent rivals.
✅ The Pros
- No Monthly Fees: Local storage is fast, private, and free.
- Dual Camera Tech: Total coverage of both people and packages.
- Dual-Band Wi-Fi: Supports both 2.4GHz and 5GHz for stable streaming.
- Color Night Vision: Dual built-in spotlights illuminate the porch at night.
- Fast Response: Near-instant notifications to your smartphone.
❌ The Cons
- Larger Size: The dual-lens setup makes it thicker than standard doorbells.
- Battery Charging: Unlike Ring, you have to remove the entire unit or use a tool to pop the battery.
- No HomeKit: Apple users will find no native support for the Home app.
🤖 3. Delivery Guard: AI That Actually Works
The E340 isn't just a passive recorder; it's an active guard. The Delivery Guard feature uses the bottom camera to detect when a package is dropped off. But it goes a step further: it will send you a "Package Left" notification and can even play a pre-recorded message or sound a siren if it detects a stranger lingering near the box for too long.
During our testing, the AI was surprisingly accurate at distinguishing between a stray cat and a cardboard box, a feat that many cheaper doorbells fail at. This level of intelligence is what separates a generic camera from a top-tier wireless doorbell.
🔋 4. Power Options: Battery or Hardwired?
Eufy offers incredible flexibility with the E340. You can run it entirely on its rechargeable battery, which typically lasts between 3 to 6 months depending on the "Motion Detection" settings. If you choose this route, installation takes less than 10 minutes with just two screws.
However, if you have existing doorbell wires, you can hardwire the E340. This keeps the battery permanently topped up and allows the camera to record a few extra seconds of "pre-roll" footage, ensuring you never miss the very start of an event.
🌑 5. Night Vision & Clarity
Nighttime performance is where many wireless cameras struggle. The Eufy E340 uses two high-powered LEDs that act as mini-floodlights. When someone approaches your door at 2:00 AM, the lights trigger, and you get a full-color 2K video. This is far superior to the grainy black-and-white infrared footage found on older models. If you prefer to stay stealthy, the infrared mode is still available and offers impressive range.
🏆 6. Final Verdict: The Best Value in 2026
The Eufy Video Doorbell E340 is the perfect device for the modern, privacy-conscious homeowner. It eliminates the hidden costs of smart home ownership while providing a level of physical security—via the dual-lens system—that rivals much more expensive professional installations.
While the Ring Pro (featured in our comparison of top-rated video doorbells) might have slightly better radar precision, Eufy’s package detection and "No-Monthly-Fee" promise make it the better overall value for 90% of users.
