Who Is This Review For?
I've worked in UK security for over 20 years. I've recommended video doorbells to hundreds of homeowners across East London — people who want real security, not marketing fluff.
The Eufy E340 kept coming up as the recommendation I make most often. This review explains exactly why — and where it falls short.
What's in the Box
- Eufy Video Doorbell E340 unit
- Mounting bracket and screws
- Wall anchors
- Security screw with specialist bit
- USB-C charging cable
- Indoor chime unit ✅ — included, unlike Ring
The included chime is a significant advantage over Ring and Nest, which charge extra for their indoor chime units. Out of the box, the E340 works as a complete system.
The Dual Camera — Why It Matters
The headline feature of the E340 is its dual-camera setup — and it's genuinely useful rather than a marketing gimmick.
Main camera (2K, facing forward): Captures visitors' faces, clothing, and the area in front of your door. Excellent detail — enough to identify faces at 3–4 metres in daylight, and usable at night thanks to colour night vision.
Package camera (1080p, facing downward): Points at the ground in front of your door. Captures parcels left on the doorstep, people who crouch below the main camera's view, and the feet and lower body of anyone standing at the door.
In my 20 years in security, I've seen footage where the main camera captured a hooded face but the package camera clearly showed distinctive trainers — enough for police identification. The dual view matters.
Delivery Guard: Eufy's AI feature that sends specific alerts when a package is detected on the doorstep, and another alert if it's removed — potentially indicating theft. Works reasonably well for larger parcels. Smaller packages are occasionally missed, but performance has improved with recent firmware updates.
Video Quality
Daytime: Excellent. The 2K main camera provides sharp, detailed footage with good colour reproduction. HDR processing handles difficult lighting conditions — bright afternoon sun, mixed shadow and light — better than most doorbells at this price.
Night vision: Colour night vision on the main camera is genuinely impressive. Unlike infrared (which produces black-and-white footage), colour night vision lets you see clothing colours, vehicle colours, and other identifying details. In East London's well-lit streets, the footage is close to daytime quality.
Package camera night vision: The downward camera uses infrared — adequate for detecting parcel placement but without the colour detail of the main camera.
Battery Life — A Genuine Advantage
The E340's 6,500mAh battery is one of the largest in any consumer video doorbell. Eufy claims up to 6 months per charge — in UK real-world conditions, expect 4–6 months depending on traffic at your door.
For comparison:
- Ring Battery Doorbell Plus: 3–6 months (smaller battery)
- Google Nest Doorbell Battery: 2–2.5 months
In practice, charging twice a year versus five or six times a year is a meaningful quality-of-life difference.
Cold weather note: Like all battery doorbells, the E340's battery life drops in winter. In particularly cold UK winters, expect 3–4 months rather than 6. Wired installation (if you have doorbell wiring) eliminates this issue entirely — the wiring trickle-charges the battery continuously.
Local Storage — The Privacy Advantage
The E340 includes 8GB of built-in storage — enough for several days of event footage at typical UK residential activity levels. This is stored on the device itself, not on Eufy's cloud servers.
Why this matters:
- Privacy — your footage doesn't leave your home
- Evidence preservation — even if your internet drops, events are recorded locally
- No subscription required — the storage works without paying anything ongoing
- If the device is stolen — footage is gone (this is the trade-off vs. cloud storage)
The 8GB cannot be upgraded via microSD on the standalone E340. However, if you already own a Eufy HomeBase (from other Eufy security cameras), the E340 connects to it and uses the HomeBase's expandable storage — up to 16TB.
App and Setup
The eufy Security app is clean, well-organised, and reliable. Setup takes approximately 20–30 minutes including mounting.
Strengths:
- Event timeline is easy to navigate
- Activity zone configuration is intuitive
- Facial recognition — trains from footage to recognise regular visitors (postman, family members)
- Live view loads in 2–3 seconds
Weaknesses:
- Notifications are slightly slower than Ring — averaging 3–5 seconds vs Ring's 2–3 seconds
- The app occasionally has connection delays when loading live view on slower mobile data
Neither weakness is a dealbreaker, but Ring's app remains marginally more responsive.
No Subscription — The Real Selling Point
This is where the E340 changes the financial calculation entirely.
5-year cost comparison:
| Doorbell | Hardware | Subscription (5yr) | Total |
|---|---|---|---|
| Eufy E340 | ~£160 | £0 | ~£160 |
| Ring Battery Plus | ~£130 | ~£300 | ~£430 |
| Google Nest Battery | ~£160 | £0–£360 | £160–£520 |
The E340 is the cheapest option over any period longer than one year — despite costing more upfront than Ring.
All features — AI detection, local storage, facial recognition, Delivery Guard, colour night vision — work without paying a penny monthly. There is no feature paywall.
What Could Be Better
Notification speed: Ring is faster. For security-critical use, a 2-second notification is better than a 4-second one.
Package camera resolution: 1080p is adequate but the main camera's 2K quality would be better for the downward-facing lens.
App stability: Occasional connection delays in the app. Not frequent enough to be a major issue but worth mentioning.
No HomeKit support: Apple HomeKit users will need to look elsewhere — the Arlo Essential 2K is the best HomeKit option.
Motion detection type: The E340 uses standard PIR + AI detection rather than the radar-based detection in Eufy's more expensive E330/S330 models. This means occasional missed events in low-traffic scenarios. In practice, detection reliability is good but not quite at the level of radar-equipped models.
Who Should Buy the Eufy E340?
Buy it if:
- ✅ You want no subscription — now or ever
- ✅ You receive frequent parcel deliveries
- ✅ Privacy matters — local storage, no cloud dependence
- ✅ You're thinking long-term — it's the cheapest option over 5+ years
- ✅ You use Alexa or Google Home
- ✅ You want colour night vision
Don't buy it if:
- ❌ You're in the Apple HomeKit ecosystem → Arlo 2K
- ❌ Fastest possible notifications are critical → Ring Battery Plus
- ❌ You're renting short-term and budget is tight → Eufy C30
- ❌ You're already deep in the Google ecosystem → Nest Doorbell
My Verdict
After 20 years in security, I've seen a lot of home security products come and go. The Eufy Video Doorbell E340 is the one I recommend most often to UK homeowners — not because it's perfect, but because it solves the right problems.
No subscription. Dual cameras. Local storage. Colour night vision. A battery that lasts half a year. And a chime included in the box.
Ring and Nest have stronger brand recognition and slightly more polished apps. But over any meaningful time horizon, the E340 is cheaper, more private, and functionally superior for the specific job of protecting a UK front door.
Score: 9/10 — The best video doorbell for most UK homeowners in 2026.
