The Eufy SoloCam S220 is a different tool: a wire-free, IP67 outdoor camera with a solar panel, which the plug-in Eufy Indoor Cam C120 cannot be. The two share 2K video, 2.4 GHz Wi-Fi only, two-way talk, a siren and support for Alexa, Google Home and Home Assistant. Storage is where they part ways, since the Eufy Indoor Cam C120 records to a microSD card and offers an optional cloud plan while the Eufy SoloCam S220 keeps clips only in its own 8 GB. Choose the Eufy Indoor Cam C120 for a nursery, a pet room or a HomeKit home, and the Eufy SoloCam S220 for a driveway or garden with no power nearby.

What the differences mean

Where it can live

The Eufy Indoor Cam C120 is a plug-in camera with no weather rating, so it stays inside. The Eufy SoloCam S220 is IP67 and runs on a rechargeable battery with solar charging, which is what lets it watch a gate or a garden with no cable.

Storage

The Eufy Indoor Cam C120 has 8 GB built in plus a microSD slot and an optional cloud plan, so you can grow the archive. The Eufy SoloCam S220 has 8 GB and nothing else: no card slot and no cloud, so a busy scene fills it sooner.

Smart home support

Both work with Alexa, Google Home and Home Assistant, but only the Eufy Indoor Cam C120 supports Apple HomeKit. It also offers an RTSP stream for other recorders, which the Eufy SoloCam S220 does not.

AI alerts

The Eufy Indoor Cam C120 detects motion, people, animals and a baby crying on its own. On the Eufy SoloCam S220, people detection is on the camera, while animals, vehicles and familiar faces need a HomeBase S380.

Field of view

The Eufy SoloCam S220 sees 135 degrees diagonally. The Eufy Indoor Cam C120 is listed at 125 degrees horizontally, so the two are close, and neither pans or tilts.

Which one to buy if

What owners say

Owners of both Eufy cameras agree on the appeal: a sharp 2K image, a setup that takes minutes and footage kept on the camera instead of behind a monthly fee. Eufy Indoor Cam C120 owners single out the HomeKit support, the privacy of local recording and the way it works without a HomeBase, and they warn that the microSD slot only takes cards up to 128 GB and that a renewed unit can arrive damaged. Eufy SoloCam S220 owners talk about the one-screw install and a battery that stays topped up in a sunny spot, while they report charging it by cable in shade or winter and mixed results from motion detection that needed tuning. Some pet, vehicle and face features on the Eufy SoloCam S220 also sit behind a HomeBase S380.

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
