Eufy SoloCam S340 Review: The Dual-Lens Solar Security Camera Worth Knowing
A close look at the Eufy SoloCam S340 dual-lens solar security camera: 360° pan, 3K wide plus 2K telephoto, and no monthly fees.

Most solar cameras give you one wide view and call it a day, fine for recording a porch, useless for reading a license plate at the end of the driveway. The S340 fixes that by stacking a 3K wide-angle lens (2880×1620) on top of a dedicated 2K telephoto (2304×1296), so you can watch the full yard and still zoom tight on whoever’s at the gate without switching cameras or losing resolution to a software crop.
Quick Verdict
Two lenses, one solar panel, and no monthly bill. The Eufy SoloCam S340 pairs a 3K wide-angle view with a 2K telephoto that zooms 8x, and the 2.2W panel means I’m not climbing a ladder to recharge it every few weeks.
Buy if you:
- Hate wiring cameras and want a solar-topped setup
- Want to zoom in on a driveway or gate 8x without losing detail
- Refuse to pay a monthly cloud subscription
- Need 360° pan coverage from a single mount point
Skip if you:
- Mount it in a shaded corner where the 2.2W panel barely sips sunlight
- Want familiar-face AI without buying the HomeBase S380 separately
- Need a fully wired camera that never touches a battery

Two Lenses On One Camera Is The Whole Point
The telephoto pushes to 8x zoom, and because it’s a dedicated lens rather than cropping a single sensor, you keep detail instead of a blurry mess. That’s what separates the S340 from cheaper single-lens solar cams. Two lenses working together is the pitch, and it’s a good one.
What The Eufy SoloCam S340 Actually Packs In
360° pan, 70° tilt, 8x zoom, one camera covers an entire perimeter without a hub or power cord. The camera swivels a full 360° and tilts 70°, so one unit can sweep an entire driveway, a side gate, and a chunk of the front lawn instead of staring at one fixed spot. The wide lens covers a 135° field of view.
Night vision reaches up to 40 ft (12 m), and the f/1.6 aperture pulls in about 20% more light, giving vivid images up to 26 ft (8 m). You get color night vision or infrared depending on conditions. There’s two-way audio and a built-in siren baked in for scaring off anyone who lingers too long.
Solar Power Means You Stop Thinking About Charging
The solar angle is the second reason this camera is worth a look. The built-in battery is rated for up to 3 months on a single charge at 300 seconds of recording a day, and the included 2.2W panel is meant to keep it topped off from there. In a decent sunny spot, that turns into a camera you mount once and mostly forget about.
The panel can attach right to the camera or run on a cable to a sunnier nearby location, which is a nice bit of flexibility if your ideal mounting wall happens to sit in shade. No power cord snaking down the wall, no outlet needed. Just Wi-Fi and sunlight.
The Familiar-Face AI Isn’t In The Box You Think
Here’s the catch worth flagging: the smartest AI features don’t live on the camera alone. The S340 has onboard AI for basic detection, but the good stuff, familiar faces, human recognition, vehicle detection, and pet detection through BionicMind, only kicks in when you pair it with the HomeBase S380. That’s a separate purchase.
So if you bought this expecting your phone to say “Mom is at the door” out of the box, that’s not quite the setup. The camera ships with 8 GB of local storage and works fine solo, but the HomeBase unlocks the deeper recognition and bigger storage options. Worth knowing before you assume the whole eufy ecosystem comes in one box.

Who The SoloCam S340 Actually Fits
The S340 is built for the person who wants one camera to do the work of two or three. The 360° pan means a single mount at the corner of a garage can sweep the driveway, the side gate, and part of the front lawn, spots where you’d normally need separate fixed cameras. The one hard requirement: that mounting wall needs real sun. A wall that catches four-plus hours of direct light a day keeps the 2.2W panel ahead of the battery draw; anything less and you’re recharging by cable more often than the solar pitch implies.
The 360° pan makes it a strong pick if you want one camera covering a wide area instead of buying three fixed ones. And the no-subscription angle matters if you’re the type who bristles at monthly fees. Everything records to that 8 GB local storage without a cloud plan.
Solar-Wireless vs A Traditional Wired Camera
Wired cameras hold one hard advantage: they never deplete. If you already have an outlet or PoE run at your mounting spot, a wired cam removes the battery-and-sunlight equation entirely, and that’s genuinely simpler for shaded walls or north-facing spots.
Where the S340 wins is the install itself. No cable run, no outlet hunt, no electrician, just a drill, two screws, and a Wi-Fi password. You get dual lenses and 8x optical zoom on any exterior wall in under an hour, which a PoE camera simply can’t match. If your mounting spot is shaded and you already have a wired run there, take the wired cam. Everywhere else, the SoloCam is the faster, cheaper path to coverage.
Advice Before You Mount It
Pick your mounting spot for sun first, camera angle second. A 2.2W panel is small, and if it lives in shade you’ll be recharging by cable more than you’d like. Use the panel’s cable-run option to chase sunlight if your best viewing angle sits in shadow.
Decide up front whether you want the HomeBase S380. If familiar-face recognition and expanded storage matter to you, budget for it now instead of being surprised the camera alone won’t do it. And confirm your Wi-Fi actually reaches the mounting wall before you drill, since this connects directly over Wi-Fi with no hub in between.
Pros
- True dual-lens setup: 3K wide plus 2K telephoto with 8x zoom
- 360° pan and 70° tilt from a single mount point
- Solar panel plus a battery rated up to 3 months means minimal recharging
- 8 GB local storage with no monthly subscription
- IP67 weatherproofing and a built-in siren plus two-way audio
Cons
- Best AI features (familiar faces, vehicle/pet detection) need the separate HomeBase S380
- The 2.2W panel struggles in shaded mounting spots
- Non-removable battery means the whole camera comes down if it ever needs a hard recharge
Frequently Asked Questions
Does the Eufy SoloCam S340 require a monthly subscription?
No. It records to 8 GB of built-in local storage with no cloud fee required. You only pay more if you decide to add a HomeBase for expanded storage and smarter AI.
Can I use the S340 without the solar panel?
Yes. The built-in rechargeable battery is rated for up to 3 months on a charge at 300 seconds of recording per day. The solar panel just keeps it topped off so you rarely have to bring it down and recharge by cable.
Is the SoloCam S340 weatherproof enough for winter?
It carries an IP67 rating, so it’s built to handle rain and outdoor exposure. Cold weather can shorten battery performance on any lithium camera, so a sunny mounting spot helps the solar panel keep pace.
Does it work with Alexa or Google?
Yes. It streams to an Alexa Echo Show and Google Chromecast, so you can pull up the feed on a smart display. It connects over Wi-Fi directly with no separate hub needed for basic use.
What do I need for familiar-face detection?
You need the HomeBase S380, sold separately. That’s what unlocks BionicMind AI for familiar faces, human recognition, vehicle detection, and pet detection. The camera alone handles basic detection but not the advanced recognition.
How far can it see at night?
Night vision reaches up to 40 ft (12 m). The f/1.6 aperture pulls in roughly 20% more light for vivid images up to about 26 ft (8 m), and you get color or infrared night vision depending on conditions.
Can the solar panel mount away from the camera?
Yes. The panel can attach directly to the camera or run on a cable to a sunnier nearby spot. That’s useful when your best viewing angle happens to be a shaded wall.
Is there a warranty?
Yes, eufy lists a 1-year manufacturer warranty on the SoloCam S340. Register your device through the eufy app to keep coverage straightforward if something goes wrong.
