## What reviewers say

**eufy SoloCam S340** — Two hands-on testers (PCWorld/TechHive and SafeWise) recommend the S340. Both praise its sharp dual-lens image quality (wide-angle plus telephoto zoom) and the included solar panel, which held the battery at or near 100% over weeks of real-world use. Both also value the optional (no mandatory subscription) 8GB local storage. Each flags the flimsy included mounting screws and app friction. No RTINGS/PCMag/Tom's Guide standalone review of this exact model was verified; blogs excluded. (2 sourced reviews.)
