Eufy E340 Floodlight Camera Review
Bottom Line
Choose the Eufy E340 for bright hardwired floodlight coverage, sharp dual-lens video, local storage, and no required subscription. Skip it if you need HomeKit, battery power, or the smallest outdoor camera.
Best for
Best for homeowners or small businesses replacing an existing floodlight who want wide yard or driveway coverage, bright lighting, local recording, and AI tracking without a mandatory monthly fee.
Not for
Not for renters, Apple HomeKit households, or anyone who needs battery/solar placement flexibility, compact styling, PoE/ONVIF support, or full third-party automation compatibility.
Verdict
The Eufy E340 stands out as a hardwired floodlight camera with sharp dual-lens video, strong lighting, wide pan-and-tilt coverage, and unusually flexible local storage. Reviewers consistently praised the detail, night vision, AI tracking, and no-subscription value, especially when paired with HomeBase for more storage and features. The tradeoff is ecosystem flexibility: it works well with Alexa and Google, but HomeKit, IFTTT, Matter, ONVIF, and battery-powered placement are weak or absent. False alerts appear in some testing, and the 15 fps frame rate can blur fast motion, but most evidence still points to a capable, high-value outdoor security camera.
