It pairs a wide lens with a telephoto that pans 355 degrees and tilts 70 degrees to follow movement, charges its battery from solar or runs wired, keeps clips on 32GB built in plus microSD, streams RTSP, detects people, animals and vehicles with no plan and is weatherproof to IP65. The Ring Indoor Cam is the tiny, very cheap and better reviewed room camera: 1080p, color night vision, two-way audio, a physical privacy cover and privacy zones, with nothing saved unless you pay for Ring Protect. Choose the Eufy Cam S4 to guard a driveway or a large property, and the Ring Indoor Cam for a pet, a baby or a bedroom in a Ring or Alexa home.

What the differences mean

Indoor or outdoor

The Eufy Cam S4 is rated IP65 for walls and eaves outside. The Ring Indoor Cam is not weather resistant; owners point it out of a window, but it is a room camera.

Coverage and resolution

The Eufy Cam S4 records 4K through a 130 degree wide lens plus a pan-tilt telephoto that follows movement. The Ring Indoor Cam records 1080p through a fixed 115 degree horizontal view, plenty for one room.

Recording

The Eufy Cam S4 stores video on 32GB of built-in storage and a microSD card of up to 256GB, and streams RTSP. The Ring Indoor Cam has no local storage: without Ring Protect you get live view only.

Power

The Eufy Cam S4 runs on a battery with solar charging or on a power cable, which adds 24/7 history. The Ring Indoor Cam plugs into the wall and has no battery.

Size

At 73g the Ring Indoor Cam sits unnoticed on a shelf. The Eufy Cam S4 weighs 745g, a substantial dual-lens unit meant to be mounted.

What owners say

Owners of both cameras praise the image for what they bought it to do and grumble about something in the software around it. Eufy Cam S4 owners rave about the dual-lens tracking, one lens holding the wide view while the other zooms after movement, and value 4K footage stored locally with solar keeping the battery topped up; they report 2.4 GHz Wi-Fi struggling in crowded networks, uneven vehicle detection and a slow eufy app. Ring Indoor Cam owners use it as a cat, dog, baby or bedroom monitor, calm pets through clear two-way audio and like the privacy cover and motion zones, all set up in a few minutes. Their complaints are no saved video without Ring Protect and a blurry black-and-white image in near-total darkness.

Price history compared

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