Eufy Indoor Cam S350 Review
Eufy Indoor Cam S350 is excellent detail, local storage and tracking; privacy evidence is mixed. Two-way audio is less refined than video.
At a Glance
Eufy Indoor Cam S350 is a current US indoor camera suited to buyers wanting high detail, tracking and local recording in a large room. Its main tradeoff is two-way audio is less refined than video.
Technical Assessment
Dual-lens 4K/2K setup with genuine 3x optical zoom (not purely digital) puts it in similar territory to the Aqara G350, though with a narrower field of view (130 vs 133 degrees) and no HomeKit support. Standalone microSD capacity (128GB) is meaningfully lower than competitors advertising 512GB support, though a HomeBase adds capacity. No dimensions or weight were published on the official spec sheet.
Performance
Independent testing consistently describes sharp video and capable tracking. The dual lenses make distant details more usable than digital zoom alone, although audio is merely adequate.
Features and Workflow
The feature set combines Local Storage: MicroSD card, up to 128GB (camera-only, without HomeBase), Camera: Dual camera: 4K wide-angle + 2K telephoto, and Warranty: 12 months hardware warranty from purchase date (Security Camera category); 2-year software update support. Together, these capabilities support more complete day-to-day workflows and reduce reliance on a single headline specification.
Reliability and Ownership
Review testing found operation reliable and consistent, but no comparable long-duration failure-rate dataset was located.
