It stitches a 180 degree panoramic view, records 24/7 to a card of up to 512GB, streams over RTSP, joins 2.4 or 5 GHz Wi-Fi or Ethernet and carries a two-year warranty. The Eufy SoloCam S230 is the cheaper, slightly better reviewed camera and the only one of the two that needs no cable: its integrated solar panel keeps the battery topped up, and it records 2K events to 8GB of built-in storage. Both have color night vision, a spotlight and a siren. Pick the Reolink Duo 3 WiFi for continuous coverage of a wide driveway, and the Eufy SoloCam S230 for a spot where no outlet reaches.

What the differences mean

Power

The Eufy SoloCam S230 is wire-free, with a battery rated for about 4 months that its built-in solar panel keeps charged. The Reolink Duo 3 WiFi has no battery and runs on 12V from an outlet.

What it records

The Reolink Duo 3 WiFi keeps a 24/7 video history on a microSD card of up to 512GB. The Eufy SoloCam S230 records motion events to its 8GB of built-in storage, with no microSD slot, so a busy scene fills it faster.

Field of view and resolution

The Reolink Duo 3 WiFi records 4K across a stitched 180 degree horizontal view, built for driveways and wide yards. The Eufy SoloCam S230 records 2K with a 135 degree view, which covers a garden or an entrance.

Connection and integrations

The Reolink Duo 3 WiFi joins 2.4 or 5 GHz Wi-Fi, has an Ethernet port and streams RTSP. The Eufy SoloCam S230 is 2.4 GHz only with no RTSP, but it works with Alexa, which the Reolink does not.

Which one to buy if

What owners say

Owners of both cameras like keeping their footage local, with no monthly fee. Eufy SoloCam S230 owners are most enthusiastic about the solar panel, with reports of the battery staying high for a year through cloudy spells, plus a two-screw install and a wide view that covers a whole yard. Their complaints are a lag between an alert and a playable clip, storage capped at the built-in 8GB, and in-app ads some saw for a while. Reolink Duo 3 WiFi owners single out a crisp panoramic image with almost no fish-eye and a Wi-Fi link that stays stable at distance, and they warn that the 180 degree view is wasted in a small room, that zoomed distant subjects get grainy and that first setup can need a wired connection.

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.
