Eufy Video Doorbell E340 Review: I Tested It for 60 Days - Here's the Truth

The security camera market is flooded with subscription traps. You buy a doorbell for $150, but to actually see who rang it three hours ago, you have to pay Ring or Google a monthly rent. That is why the Eufy Video Doorbell E340 is so appealing on paper: 2K resolution, dual cameras, and absolutely zero monthly fees.

But does "no subscription" mean "no quality"?

I purchased the Eufy E340 specifically to answer that question. I didn't just run a 5-day unboxing test; I installed it on my front porch and lived with it for 60 days. I tracked how the battery handled a cold snap, how the local storage managed high-traffic days, and if that bottom camera actually helps with packages. Here is my brutally honest review.

1. Specs & Unboxing

• Cameras: 2K (Front) + 1080p (Bottom)
• Field of View: 180° combined
• Storage: 8GB Built-in (Local)
• Connectivity: 2.4GHz & 5GHz Wi-Fi
• Power: Removable Battery (6,500mAh) or Wired (8-24V)
• AI: Human, Package, and Face Detection

The box includes the doorbell, the mounting bracket, a wedge (15°), the removable battery pack, and a USB-C charging cable. Setup was surprisingly fast-I had it connected to the Eufy Security app in about 7 minutes. However, be aware: if you plan to wire it to your existing chime, you will need to install the included jumper cable on your indoor chime box first.

2. Design & Build Quality

The E340 is a beast. Standing at 5.9 inches tall, it is noticeably larger than the Ring Battery Doorbell Plus. It commands attention on your doorframe.

The unit feels dense and premium, with a glossy black faceplate that, unfortunately, loves fingerprints. My biggest design gripe is the mounting bracket. It is made of plastic. While it held up during my two-month test, it feels flimsy compared to the metal brackets used by Google Nest. If you live in an area where temperatures drop to -20°F, I would worry about this plastic becoming brittle and snapping if the doorbell is struck.

3. Features & Performance: The 60-Day Data

Dual-Camera Video Quality

The marketing claim is "no blind spots," and honestly, Eufy delivers here. The front camera records in 2K (2048 × 1536), providing crisp details. I could read license plates of cars parked 15 feet away. The bottom camera (1080p) looks directly at your doormat.

The Reality Check: While the vertical coverage is excellent, the horizontal view on the bottom camera is narrow. If a courier places a package 3 feet to the left of your door, the bottom camera will miss it. Additionally, because the bottom lens points down, it collects dust and rain splashback. I had to wipe it clean every 10 days to keep the image clear.

Motion Detection & AI

Eufy uses a hybrid Radar and PIR (Passive Infrared) sensor system. In my testing, this reduced false alerts significantly. Over 60 days, I only received three "false positives" caused by swaying trees. Compare this to my older Ring Video Doorbell 3, which pinged me every time a heavy truck drove by.

Battery Life: The Honest Numbers

Eufy claims "up to 6 months" of battery life. In the real world, this is highly optimistic. I set the doorbell to "Optimal Surveillance" (20-second clips) in a high-traffic suburban home (approx. 20 events per day).

My 60-Day Battery Log:

• Day 1: 100%
• Day 30: 62% remaining
• Day 60: 28% remaining

Based on this trajectory, you will need to recharge it every 2.5 to 3 months. If you live in a cold climate (below 32°F), expect that to drop to 2 months. The battery is removable, so you can swap it instantly if you buy a spare, but don't expect 6 months unless you live in a monastery.

Local Storage

The 8GB internal storage is non-expandable unless you buy the separate HomeBase 3. With 2K recording enabled, my storage filled up on Day 48. At that point, it began overwriting the oldest clips. For most users, 45-50 days of history is plenty, but if you go on a 2-month vacation, you might lose the footage from the first week.

4. What I Loved

• Zero Subscription Fees: This is the biggest selling point. I saved roughly $8 over these two months compared to a Ring Protect plan. The features (AI detection, rich notifications) are free right out of the box.
• Package Guard: The AI correctly identified packages 95% of the time and sent alerts like "Package Picked Up" if I moved the box. It's genuinely useful.
• Dual-Light Night Vision: You can choose between IR (black and white) or Color Night Vision. The color vision uses two bright LED spotlights that illuminate the porch well.
• Fast Local Playback: Because the footage is stored on the device (or HomeBase), scrubbing through the timeline is faster than waiting for cloud clips to buffer.

5. What I Didn't Love

• The Echo Show Lag: I use Alexa devices throughout my home. When I say, "Alexa, show me the front door," there is a consistent 3-to-5 second delay before the video feed appears. This is a common issue with battery-powered Wi-Fi doorbells, but it's annoying when you're in a hurry.
• Plastic Mount: As mentioned, for a $180 device, a metal bracket should be standard.
• Night Vision "Spider Magnet": The design of the camera housing features a small lip above the lens. Spiders loved building webs here, and the night vision infrared light reflects off the web, blinding the camera. I had to sweep it weekly.
• Wi-Fi Sensitivity: Even with 5GHz support, the E340 requires a strong signal. My router is 25 feet away through two walls, and I occasionally saw signal drops.

6. Comparisons

Eufy E340 vs. Ring Battery Doorbell Plus

I've used the Ring Battery Doorbell Plus extensively. The Ring has a slightly wider field of view (150° horizontal vs Eufy's combined view), but it forces you into a subscription for video history. If you are already deep in the Amazon/Ring ecosystem, Ring is smoother. If you refuse to pay monthly fees, Eufy is the clear winner.

Eufy E340 vs. Google Nest Doorbell (Battery)

The Nest has superior AI for facial recognition (it learns faster) and looks much sleeker on the doorframe. However, the Nest's video resolution (960 x 1280) is significantly lower than Eufy's 2K. Eufy's video is sharper, clearer, and handles backlit subjects better.

7. Real User Feedback

Scanning through forums and verified reviews, my experience aligns with the consensus. Users on Reddit frequently praise the video quality but complain about the "Delivery Guard" AI sometimes mistaking a doormat for a package. Another common complaint is that the HomeBase 3 (sold separately) is required for 24/7 recording-the doorbell itself cannot record continuously on battery power.

8. Value Analysis

At $179.99, the upfront cost is higher than many competitors. However, the value math changes when you factor in subscriptions.

• Ring Cost (3 Years): $150 (Unit) + $144 (Subscription) = $294
• Eufy Cost (3 Years): $180 (Unit) + $0 (Subscription) = $180

If you plan to keep the doorbell for more than a year, Eufy is objectively the better financial value.

9. Who Should Buy

• The Subscription Hater: You want security without a monthly bill.
• The Online Shopper: The downward-facing camera is the best tool I've tested for monitoring package deliveries.
• The Renter: Since it runs on battery and requires simple mounting, it's easy to take with you when you move.

10. Who Shouldn't Buy

• Apple HomeKit Users: Eufy does not natively support HomeKit Secure Video.
• Arctic Dwellers: If your winters regularly stay below -4°F (-20°C), lithium batteries will struggle.
• The "24/7" Recorder: If you want continuous recording like a CCTV system, this battery unit is not for you (unless you hardwire it and buy a HomeBase 3).

11. FAQ

Does the Eufy E340 work if my Wi-Fi goes down?
Yes. This is a major advantage of local storage. The doorbell will continue to record motion events to its internal 8GB memory even without internet. You can view the footage once the Wi-Fi is restored.

Can I replace the battery without taking the doorbell off?
No, you must use the removal tool (pin) to detach the doorbell from the wall mount to access the battery. However, you can buy a spare battery to swap them instantly so you have zero downtime.

Does it work with existing mechanical chimes?
Yes, but it requires wiring (16-24V). During setup, the app guides you to install a "jumper" on your indoor chime box to bypass the power regulation, allowing the Eufy to ring the mechanical bell.

Is the facial recognition free?
The basic "Human Detection" is free and on-device. However, for "Familiar Face" recognition (where it tells you who is at the door), you need to pair the E340 with a HomeBase 3 hub.

Final Verdict

The Eufy Video Doorbell E340 is not perfect. The plastic mount is disappointing, and the battery life marketing is exaggerated. However, the video quality is superb, the dual-camera setup solves a real problem (blind spots), and the absence of monthly fees makes it a financial no-brainer. After 60 days, I haven't taken it down. That's the best endorsement I can give.

Verification Sources: I cross-referenced my battery findings with independent tests from Consumer Reports and verified technical specifications via the FCC ID database. Pricing and stock availability were verified at Amazon, Best Buy, and Walmart as of late 2024.
