The verdict
If you hate subscription fees, this is the smart doorbell to buy. Dual-camera setup catches packages on the porch in a way single-lens units cannot.
Test results
| Signal distance | Wi-Fi dependent (dual-band 2.4/5 GHz) |
|---|---|
| Wall penetration / interference | Bound by home Wi-Fi reach |
| Loudness (peak dB at 1 m) | Optional plug-in chime included; ~85 dB |
| Battery life | 2–4 months between charges (dual cameras draw more than single-lens units) |
| Mobile phone integration | Eufy Security app, iOS + Android, ~2 s push |
| Smart home integration | Alexa, Google Assistant — no HomeKit, no Matter at this time |
What I liked
- Dual cameras: standard front view plus a downward-facing camera for the porch
- Local storage on the included HomeBase or microSD — no subscription required
- 2K resolution, solid HDR
What I did not
- Battery life is the shortest in this category — plan on charging every 2–3 months
- No HomeKit support
- App can feel busy compared to the Nest experience
Full review
The Eufy E340 is the answer to "I want a Ring or Nest but I do not want to pay $5 a month forever." It records to local storage by default, includes a plug-in chime in the box, and the dual-camera setup means you can actually see whether a package on the porch is yours or your neighbor's.
Image quality is on par with the Nest. The downward-facing second camera is a genuinely useful feature that almost no one else ships.
The trade-off is battery life. Two cameras means twice the draw, and in normal use I was charging every 8–10 weeks. If that is annoying, hardwire it.
Smart home support is limited to Alexa and Google Assistant. No HomeKit. If you are an Apple house, this is not the doorbell for you.
