It shoots 4K through a fixed wide lens plus a pan-tilt telephoto that follows movement, runs on a solar-charged battery or on power, stores clips on 32GB built in plus microSD, streams RTSP, detects people, animals and vehicles and is weatherproof to IP65. The Ring Indoor Cam Plus answers a different need at a fraction of the price: a better reviewed plug-in indoor camera with 2K HDR video, color night vision, a physical privacy cover and privacy zones, which saves nothing without a Ring Protect plan. Pick the Eufy Cam S4 for a driveway or a large yard, and the Ring Indoor Cam Plus for a nursery, a pet cam or a living room in a Ring or Alexa home.

What the differences mean

Indoor or outdoor

The Eufy Cam S4 is rated IP65 and built for walls and eaves. The Ring Indoor Cam Plus is not weather resistant and is made for rooms.

Coverage

The Eufy Cam S4 pairs a 130 degree wide lens with a telephoto that pans 355 degrees and tilts 70 degrees to follow movement. The Ring Indoor Cam Plus is a fixed camera with a 115 degree horizontal view that you angle by hand.

Recording without a plan

The Eufy Cam S4 keeps video on 32GB of built-in storage and a microSD card of up to 256GB, and streams RTSP. The Ring Indoor Cam Plus offers live view only until you pay for Ring Protect, with no local storage at all.

Detection

The Eufy Cam S4 tells people, animals and vehicles apart without a plan. On the Ring Indoor Cam Plus, person detection needs a subscription and there are no animal or vehicle alerts.

Privacy

Both let you mask privacy zones. The Ring Indoor Cam Plus adds a physical privacy cover, which is what many buyers want in a bedroom or a nursery.

What owners say

Owners of both cameras describe a sharp picture, and both have complaints aimed at the software around it. Eufy Cam S4 owners rave about the dual-lens tracking, praise 4K day and night and value storing footage locally with solar keeping the battery topped up. They report 2.4 GHz Wi-Fi struggling in crowded networks, uneven vehicle detection on long driveways and a heavy, slow eufy app. Ring Indoor Cam Plus owners talk about a setup of under five minutes, fast and neatly sorted alerts and a privacy cover they actually use, and it is a favorite nursery and pet cam. Their complaints are that nothing is saved without Ring Protect, that the 2K image pixelates when zoomed in, and occasional disconnects on a weak signal.
