eufy SoloCam S340

Best for: No-subscription households that want one camera to watch a whole yard
Product review
The SoloCam S340 pairs a 3K wide-angle lens with a 2K telephoto, so it can watch a whole yard and zoom 8x into a face or plate, panning 355 degrees and tilting 70 to follow movement. The storage truth is the best in this ranking: recordings save to 8GB of built-in local storage, person and vehicle detection runs on the camera, and live view, playback and alerts all work with no subscription — eufy's optional cloud plan adds backup, not basic function. The detachable 2.2W solar panel keeps the battery topped up in decent sun. Its limits are a 2.4GHz-only radio and no continuous recording.
- Dual lenses — 3K wide plus 2K telephoto with 8x hybrid zoom
- Pan-and-tilt tracking covers a whole yard from one mount
- Local storage and on-device detection — no monthly fee
- Solar panel included; roughly three months per charge without sun
- Color night vision with built-in spotlight
- 2.4GHz Wi-Fi only — no 5GHz band
- 8GB of storage fills quickly at busy spots and cannot be expanded on the camera
- No 24/7 continuous recording
- eufy's 2022 cloud controversy still shadows the brand (see Company)
The company
eufy is the smart-home brand of Anker Innovations, founded in 2011 and headquartered in Shenzhen, China, with US operations based in Bellevue, Washington. Its privacy record carries the category's most instructive failure: in late 2022, researchers showed that cameras marketed as local-only were uploading notification thumbnails to Anker's cloud and that web-portal streams were not end-to-end encrypted, contrary to the company's marketing. Anker apologized, disclosed the thumbnail practice in its app, moved streams to WebRTC with end-to-end encryption, and commissioned independent security audits. Anker said the flaw was not exploited and no customer data was exposed — the failing was transparency, and it is scored that way here.
