Summary

The eufy Floodlight Camera E340 holds a solid rating across a growing review base. It's eufy's direct answer to Ring's Floodlight Cam Wired Plus. Both are hardwired, motion-activated floodlight cameras. But the E340 pairs its 2,000-lumen light with eufy's no-subscription local storage model and a genuinely motorized 360° tracking lens, not a fixed camera.

What Owners Praise

The 360° pan-tilt with AI auto-tracking is the standout feature. Owners report it genuinely follows a person or vehicle across the covered area. It doesn't just stay fixed on one spot, which is a real differentiator in this category. WiFi 6 support is also noted as more reliable on modern routers than older WiFi standards. The no-HomeBase-required flexibility and local microSD recording round out the praise.

What Owners Complain About

The hardwired-only installation is a mains-voltage junction-box job. That's the same as Ring's equivalent floodlight camera, and it's not a DIY option for everyone. Some reviews note the average rating, while solid, sits behind eufy's higher-rated indoor products. 3K resolution is sharp, but it's a step below the 4K options in premium cameras.

Design and Build Quality

The E340 follows the visual language most hardwired floodlight cameras share. A rectangular housing carries the camera and pan-tilt motor, centered between two adjustable floodlight heads. It mounts to a wall or eave via a junction-box backplate, not a freestanding fixture. eufy's spec page lists an IP65 weather rating — the standard owners expect from a fixture built to sit outdoors year-round through rain, dust and temperature swings. Because the E340 is hardwired rather than battery-powered, the build doesn't need a large battery compartment. Owners generally describe the housing as solidly built, with no obvious flex in the mounting arm even with the motorized lens moving inside it. The finish is a straightforward matte white or dark housing, depending on the specific listing — closer in look to a traditional security floodlight than to eufy's rounder, consumer-styled indoor cameras.

Installation Experience

The E340 is a mains-voltage AC 100V-240V fixture, per eufy's own spec page. It installs into an existing UL-listed junction box, not through a simple screw-and-charge process. That's the same category of install as any hardwired floodlight, including Ring's Floodlight Cam Wired Plus. Owners replacing an existing hardwired floodlight in the same spot generally describe the physical mounting as straightforward, since the fixture reuses the existing box and wiring. The extra step, compared to a plain floodlight, is pairing the camera to WiFi and configuring the eufy Security app afterward. Anyone without an existing junction box in the right spot, or without experience working with household wiring, is better off budgeting for an electrician. That's a real distinction to weigh against a battery-powered floodlight camera, if a simpler install matters more than motorized tracking. Confirm your box's exact wiring configuration against eufy's installation guide before ordering.

AI Tracking and App Experience

The 360° pan-and-tilt lens is the E340's defining feature. Per eufy's spec page, it pairs with AI-based auto-tracking that follows a detected person or vehicle across the covered area, rather than staying fixed on the spot where motion first triggered. Owners report this genuinely works as described — the camera visibly swivels to keep a moving subject in frame. That's a meaningfully different experience from a fixed-lens floodlight camera, which only sees whatever falls within its single static angle. The eufy Security app handles live view, playback, motion zone configuration and push notifications. Since the E340 doesn't require a HomeBase, setup runs through direct WiFi pairing in the app rather than a separate hub-pairing step. Reviewers describe notification speed as prompt enough to catch a person approaching the door in near-real time — what matters most if you're using the floodlight as an active deterrent, not just a passive recorder.

Local Storage and No-Subscription Model

The E340 records to a microSD card up to 128GB, entirely without a subscription. eufy notes that continuous 24/7 recording needs either that microSD card or a HomeBase S380 connection, and how many days a card holds depends on the card size and recording settings. Owners who want longer retention, or centralized management across multiple eufy cameras, can add a HomeBase S380, which eufy says takes up to 16TB of expandable storage. But per eufy's own product page, a HomeBase isn't strictly required for the E340 to function. That's a genuine point of difference from camera systems that gate meaningful storage behind a hub purchase or a monthly plan. Dual-band WiFi 6 with WPA3 encryption, also listed on the spec sheet, is worth noting for anyone on a modern mesh router. WiFi 6 devices generally hold a more stable connection on congested 5GHz bands than older WiFi 5 hardware — useful for a camera meant to stream live video and push alerts reliably.

What Consumer Reports says. Consumer Reports has tested the E340 and lists it among the floodlight cameras in its best floodlight cameras roundup. Its public product page describes a 3K primary camera with optional microSD storage up to 128GB, paid cloud storage and wired or solar power. We have not seen its detailed test results, which sit behind a membership.

Floodlight Performance and Motion Response

At 2,000 lumens and a 4,000K color temperature, per eufy's spec sheet, the E340's light output is genuinely usable for a driveway or backyard, not just a token accent light. The rated 100,000-plus-hour LED lifespan means owners shouldn't expect to replace bulbs the way a traditional incandescent floodlight would need. The light is motion-activated, not dusk-to-dawn by default, so it functions as an active deterrent signal the instant the camera's AI detects a person or vehicle. It doesn't just stay lit all night regardless of activity. Reviewers who compare it against a plain hardwired security light without a camera consistently point to that combination — bright, motion-triggered illumination paired with AI-tracked video — as the reason to pay more for a floodlight camera over a light-only fixture.

Who It's For

Homeowners with an existing outdoor junction box who want genuine motorized tracking coverage, plus a deterrent floodlight, without a subscription. It's a strong fit for a driveway or wide backyard, where a fixed-lens floodlight camera would miss too much.

Who Should Skip It

Renters or anyone without access to a junction box should compare against Ring's equivalent, reviewed at Ring Floodlight Cam Wired Plus review.

Pros and Cons

Pros: genuine 360° AI-tracking pan-tilt lens, no subscription required, WiFi 6, local microSD storage, works without a HomeBase.

Cons: hardwired mains-voltage install, 3K rather than 4K, rating slightly behind eufy's top indoor products.

Going Deeper: What WiFi 6 and WPA3 Actually Do for a Camera

The E340’s connectivity line — dual-band WiFi 6 with WPA3 — is easy to skim past, but both terms are defined by the Wi-Fi Alliance, the industry body that certifies WiFi products. Wi-Fi 6 was designed for “stronger performance in dense environments” and works in both the 2.4 GHz and 5 GHz bands, according to the Wi-Fi Alliance. Its main tool, OFDMA (orthogonal frequency division multiple access), “effectively shares channels to increase network efficiency and lower latency” — relevant in a home where a camera streaming live video competes with phones, TVs and laptops for the same router.

WPA3 is the security half. The Wi-Fi Alliance says users of WPA3-Personal “receive increased protections from password guessing attempts,” and that WPA3 is mandatory for Wi-Fi CERTIFIED devices (Wi-Fi Alliance security overview). For a camera, the network password is what stands between a stranger’s device and your video traffic, so resistance to guessing is a practical feature rather than a spec-sheet flourish.

The camera is only one end of that connection, and the router matters just as much. The FTC’s guidance on using IP cameras safely recommends setting a strong router password, turning on the router’s firewall, keeping its software updated and using “WPA3 or WPA2” wireless encryption. It also suggests considering a separate network for cameras, apart from computers and printers, so that a problem on the main network does not automatically reach them.

Put together, the E340’s WiFi 6 and WPA3 support give it the ingredients for a more stable and better-protected link than older hardware, provided the home network is set up to use them. For a camera mounted on the far side of a house and expected to push alerts the moment someone appears, that setup work is worth doing on installation day.

Verdict

The motorized 360° tracking is the reason to choose this over a fixed-lens floodlight camera — it's a genuine functional upgrade, not a marketing label, and it comes with eufy's usual no-subscription model. See top-rated floodlight cameras for the full comparison.
