Eufy Security SoloCam S340 (Solar Wireless Cam) Review
Solar-powered outdoor cam with dual lenses and zero monthly fees.
A wireless outdoor camera you mount once and mostly forget about, with enough solar input to skip the ladder-and-charging ritual most battery cams force on you. No subscription, ever.
What the Eufy SoloCam S340 actually is
This is Eufy's pitch for people sick of two things: charging battery cameras and paying $5 to $15 a month forever just to see your own footage. The S340 runs on a built-in solar panel, records to local storage (8GB on board), and asks for exactly zero in recurring fees. That last part is the whole reason it exists.
The headline trick is the dual-lens setup. A wide-angle lens covers the scene, a telephoto lens handles up to 3x zoom, and the camera sits on a motorized base that pans 360 degrees and tilts up to 70. So one unit watches a wide yard and can swing around to track a person walking across it. Resolution tops out at 3K. It lives outdoors with an IP67 rating and connects on 2.4GHz Wi-Fi.
How it performs day to day
The solar charging is the part owners rave about. In a spot that gets a few hours of direct sun, the S340 generally stays topped up on its own, which is the entire promise of a solar cam and one a lot of competitors fumble. Park it under heavy tree cover or a north-facing eave and you'll still be hauling it down to charge over USB-C, so placement matters more than the marketing admits.
Auto-tracking and pan-tilt are genuinely useful for covering a driveway or backyard with a single camera instead of two fixed ones. The 3K image is sharp in daylight, and color night vision holds up reasonably well with some ambient light. The flip side: pan-tilt cams have a blind spot wherever they aren't currently pointed, so a clever intruder can step through the angle the lens just left. AI detection sorts people from cars and animals decently, cutting down on the wind-blown-branch alerts that plague cheaper cams.
Local storage means your clips live on the camera, not a cloud you rent. Good for privacy and your wallet. The trade-off is that 8GB fills up, and if the camera is stolen, your footage walks off with it. Eufy sells a HomeBase hub that adds central storage and smarter features, and pairing the S340 with one is worth considering if you're building out several cameras.
The catch: Eufy's track record
You can't review a Eufy camera in 2025 without mentioning the 2023 mess, when researchers showed some Eufy cams uploaded thumbnails to the cloud and streamed unencrypted despite 'local storage, no cloud' marketing. Eufy has since rolled out end-to-end encryption and patched things, but if you bought a Eufy specifically because you distrust cloud cameras, that history deserves a hard look before you commit.
Beyond that, the app is fine but not best at anything, and there's no native Google Home or Apple HomeKit support the way Arlo and some others offer. You live inside Eufy's ecosystem.
Who should buy it, who should skip it
Buy it if you want to cover a wide outdoor area with one camera, you're done paying subscriptions, and you have a sunny mounting spot. At roughly $180 to $220 it's priced against Arlo and Ring cams that then charge you monthly to be useful, so the no-fee math gets attractive fast over a couple of years.
Skip it if your only mounting option is deep shade, if you need HomeKit or Google integration, or if the Eufy privacy history is a dealbreaker for you. People who want airtight 24/7 coverage should pair fixed cameras instead of relying on a single panning unit with a moving blind spot.
Verdict
The SoloCam S340 is one of the smarter solar cams you can buy, mainly because Eufy nailed the boring stuff: real solar self-charging, no subscription, sharp 3K, and a pan-tilt-dual-lens combo that earns its price. The blind spot and Eufy's privacy baggage keep it from a blanket recommendation. For a sunny yard you don't want to babysit, it's an easy pick.
Frequently asked questions
- Does the Eufy SoloCam S340 require a monthly subscription?
- No. It records to 8GB of built-in local storage with no recurring fees. Optional cloud backup exists, but the camera is fully functional without paying anything monthly.
- Will the solar panel keep it charged year-round?
- In a spot with a few hours of daily direct sun, yes, owners report it generally stays charged on its own. In heavy shade or short winter days you'll occasionally need to top it up via USB-C, so placement is the deciding factor.
- Does the SoloCam S340 work with HomeKit or Google Home?
- Not natively. It runs in the Eufy app and ecosystem. If you need Apple HomeKit or deep Google Home integration, look at Arlo or other brands instead.
