Eufy Cam S4 vs Ring Indoor Cam Plus

The Eufy Cam S4 is far more capable, with weatherproofing, 4K video, solar charging, a spotlight, a siren and free local storage. The Ring Indoor Cam Plus is a cheaper, highly rated indoor-only 2K camera, so it wins on price and simplicity but is limited to indoor use.

Placement and storage. The Eufy Cam S4 is a weatherproof 4K solar pan-tilt camera that records locally with no fee, while the Ring Indoor Cam Plus is an indoor-only 2K plug-in camera that stores footage in Ring's cloud and needs a subscription to record.

Only the Eufy Cam S4 is weatherproof for outdoor use, and it records locally to 32GB plus microSD with no fee. The Ring Indoor Cam Plus is indoor-only and requires a Ring Protect plan to save any footage; without one it offers only live view.

The Eufy Cam S4 records up to 4K, ahead of the Ring Indoor Cam Plus's 2K, though the Ring adds HDR. The Eufy also pans and tilts to track movement, while the Ring is a fixed camera with manual tilt for indoor rooms.

Buy the Eufy Cam S4 if you need an outdoor camera with 4K resolution, solar-charged battery, pan-tilt auto-tracking, a siren and subscription-free local storage. It is built for driveways, yards and large properties.

Buy the Ring Indoor Cam Plus if you want an easy, affordable 2K indoor camera for a Ring or Alexa home, great as a nursery, pet or room cam. Budget for a Ring Protect subscription if you want to keep recordings.
