The Floodlight Cam E340 is the one I fitted above the garage and the street-side entrance. 2000 lumens of light, two cameras, genuine PTZ. The other eufy devices around the house run on batteries; this one is hard-wired, and it does what the others can't: record around the clock in 3K. Let's see what that means in practice.
Category: Smart LED floodlight with dual-lens camera, PTZ and Wi-Fi 6
Test period: used daily for almost a year in the outdoor courtyard
Review summary (for those in a hurry):
- What it is: a camera with a 2000-lumen LED floodlight, dual 3K + 2K lenses, 360° PTZ + 120° tilt, powered from the AC mains, with 24/7 recording and dual-band Wi-Fi 6
- Who it's for: anyone who wants lighting and surveillance in a single wired device for courtyards, driveways and parking spaces, where wide coverage and strong light are needed
Floodlight and camera, done properly
The idea of a "floodlight with a camera" isn't new: Ring and Arlo have been doing it for years. What sets the Floodlight Cam E340 apart is how well eufy executes every component. The floodlight delivers 2000 lumens adjustable across three levels, enough to light a whole courtyard or a driveway up to 12-15 metres deep. The two cameras are a 3K wide-angle (2880×1620, 130° FOV) and a 2K telephoto (2560×1440) with up to 8× hybrid zoom, mounted on a motorised head that rotates 360° horizontally and 120° vertically. Everything is AC-wired: no batteries, no compromises on running time.
Dual-band Wi-Fi 6: you can feel the difference
The E340 is one of the few eufy products from 2024 to feature dual-band Wi-Fi 6 (2.4 + 5 GHz), and the difference is noticeable. Live view in 3K starts in under a second, streaming stays stable even when the home network is busy (smart TVs, gaming, video calls), and rebuffering is practically non-existent. The battery-powered cameras in the eufy range are still 2.4 GHz only to save power, and in some setups (for instance when the router is on the opposite side of the house from the camera) the difference is palpable.
Installation: it's wired, and you need to know that
This is the point that separates "buy it and fit it" from "buy it and call an electrician". The E340 has to be powered from an AC 100-240V line through a standard junction box, exactly like a traditional outdoor floodlight. If you already have a wired floodlight where you want to put it, the job takes half an hour: take down the old one, fix the universal eufy bracket, connect the three wires (live, neutral, earth) to the terminal block on the new device, mount the head and switch the power on. If the spot is "virgin" and you need to run power to it, you'll need an electrician. I'd already run a cable there when I redid the gate, so for me it was an hour's work with a screwdriver and a tester.
PTZ tracking: the most impressive way to see the dual lens
The use case that sells the E340 is PTZ tracking with the dual cameras. When the AI detects a person or a vehicle, the motorised head follows the subject and the telephoto lens zooms in on the details (face, number plate) while the wide lens keeps showing the overall scene. In real-world tests, with a subject crossing the courtyard at a normal walking pace, the system follows them all the way across without losing them, and in the saved clips you first see the wide scene, then an automatic zoom onto the face. With approaching vehicles, the zoom on the number plate is legible up to about 12-14 metres.
Floodlight: smart, not blind
The 2000 lumens are adjustable: you can set them to 30%, 60% or 100%. There are two ways to switch on: motion-triggered (it comes on only when the AI detects something, for a configurable time between 1 and 30 minutes) or scheduled (it switches on automatically at set times, typically to simulate presence). There's also a "deterrent" mode that flashes at high intensity and sounds the 100 dB siren if the AI recognises suspicious behaviour (a person standing still near a door for more than X seconds).
The light is a neutral 4000K white, not the "supermarket cold white" that some LEDs produce. Coverage is even, with no hotspots.
Storage and 24/7 recording
Being wired, the E340 can do what battery cameras can't: continuous 24/7 recording. I only switch that on in the critical spots (entrance, parking area) because it eats up storage quickly. On the current firmware, the 8 GB of on-board storage allows roughly 24 hours of continuous recording at reduced quality, or ~2 hours in 3K. For anyone who wants a serious archive, the HomeBase 3 is the logical companion: with a 4 TB hard drive I get over three months of continuous recording for the E340 alone.
Real limitations
The first: no Apple HomeKit. Even on the E340, eufy sticks to Alexa and Google Assistant. The second: no battery backup. If the power goes, the camera goes. For some setups it's worth adding a small UPS to keep things running during a blackout. The third: the E340 is big and heavy (~1.6 kg) — it isn't a "discreet" device, and it looks and feels like a real floodlight. If you're after something more camouflaged, look at the SoloCam S340 or the Wall Light Cam S100 instead.

Frequently asked questions
Can I install it myself? If you already have a wired light point where you're putting it, yes: 30-40 minutes with a screwdriver and a tester. If you need to run power from scratch, you'll need an electrician (the junction box has to meet regulations).
Does it work without the HomeBase 3? Yes. The 8 GB of on-board storage is enough for event-based use (clips on trigger). The HomeBase 3 is needed if you want continuous 24/7 recording or BionicMind face recognition.
How much power does it use? Floodlight at 100% ~30W, with the camera fully active ~35W. On standby with motion detection on ~5-7W.
Does the floodlight come on during the day if it detects movement? Not by default: the app tells day from night automatically and switches the floodlight on only after sunset (ambient light sensor). You can force it on manually.
Is it compatible with HomeKit? No, only Alexa and Google Assistant. If HomeKit is a priority for you, the Indoor Cam E220 is the HomeKit-compatible option in the range.
How does the siren behave? 100 dB is very loud (comparable to an electric drill at 1 m). It is triggered from the app or automatically on a high-priority trigger. If you have very close neighbours, some restraint may be needed: the siren works as a deterrent, but it's also a nuisance.
