Eufy S340 Review 2026: The Dual-Camera SoloCam Deep Dive
Last reviewed April 24, 2026 by Chad Simpson, Editor · Methodology
The Eufy SoloCam S340 is one of the more interesting outdoor security cameras shipping in 2026 — it packs two cameras (a wide-angle and a telephoto) into a single weatherproof outdoor unit. Solar-panel compatible, no HomeBase required, and fully subscription-free. Here's the honest product-level review.
Why Dual Cameras Matter
Single-camera outdoor cameras force a trade-off: wide field of view means objects appear small and detail is lost at distance; telephoto zoom loses peripheral context. The S340's dual-camera approach gives you both. The wide camera catches everything in frame; the telephoto gives you a sharper, zoomed-in look at specific subjects (like faces or license plates). In the app, you can switch between cameras or view both simultaneously.
Key Specs
- Wide camera: 3K resolution, ~135° field of view
- Telephoto camera: 2K resolution, 8x zoom
- Auto-tracking: Pan/tilt keeps subjects in frame
- Color night vision: Built-in spotlight for full-color low-light recording
- Weather rating: IP67 (submersion-rated dust/water protection)
- Power: 13,400 mAh battery, solar panel compatible
- Storage: 8GB built-in; expandable via HomeBase (optional)
- AI detection: On-device person, vehicle classification
- Voice: Alexa, Google Assistant
Strengths
- Dual-camera versatility. Coverage and detail in one device.
- No HomeBase required. Works standalone with built-in storage.
- Solar panel compatibility. Install once, power forever with sun exposure.
- Subscription-free core. All features work without monthly fee.
- 3K resolution. Above mainstream 2K baseline.
Watch-outs
- Price is premium for a battery outdoor cam (~$200-$250)
- Auto-tracking can be fussy with multiple moving subjects
- Battery life with both cameras active is shorter than single-cam units
- Heavier/larger than single-camera SoloCams
When The S340 Fits
- You need one camera to cover both wide-area surveillance AND close detail capture
- Driveway or front yard surveillance (ID license plates + catch the whole area)
- Single strategic mount point for maximum coverage
- You want solar + battery + no subscription all in one
Alternatives To Consider
- Eufy SoloCam E40 — Single cam, much cheaper, still no subscription
- Reolink Argus 3 Pro — Single cam, solar-ready, budget-friendly
- Arlo Ultra 2 — 4K single cam, premium, subscription-dependent
