Eufy Cam S4 vs Eufy SoloCam S220

The Eufy Cam S4 is the better overall camera, with 4K video, color night vision, a spotlight, a dual-lens auto-tracking design and generous local storage on 32GB built-in plus microSD. The Eufy SoloCam S220 is the more affordable option and adds IP67 weatherproofing, making it a strong value for a fixed 2K solar camera.

Coverage and detail set them apart. The Eufy Cam S4 shoots 4K and uses a pan-tilt zoom lens that physically follows movement, while the Eufy SoloCam S220 is a fixed 2K camera aimed once at a set area. The S220 costs much less and carries a higher IP67 weather rating.

The Eufy Cam S4 does both: it records 4K and has color night vision, where the Eufy SoloCam S220 tops out at 2K with black-and-white night vision only. For sharper detail and clearer low-light footage, the S4 is the better choice.

Yes. Both store recordings locally with no mandatory fee, the Eufy Cam S4 on 32GB built-in storage plus a microSD card, and the Eufy SoloCam S220 on 8GB of onboard storage. Both also run on battery with solar charging and expose an RTSP stream.

Buy the Eufy Cam S4 if you want the sharpest image, auto-tracking pan-tilt coverage, a spotlight and plenty of subscription-free storage from a single unit. It suits larger properties and driveways where one camera following movement across a wide area is genuinely useful.

Buy the Eufy SoloCam S220 if you want an inexpensive, truly wire-free solar camera for a sunny outdoor spot and do not need pan-tilt or 4K. Its IP67 rating and free local storage make it an easy set-and-forget pick, and many owners add several around a property.
