Its two lenses stitch a 180 degree view in 4K, it records 24/7 to a microSD card of up to 512GB, it adds color night vision, a spotlight and RTSP, and it connects over dual-band Wi-Fi or Ethernet with a two-year warranty. The Eufy SoloCam S220 plays a different game: a wire-free camera with a built-in solar panel and 8GB of storage on board, the lower priced of the two, that goes where no outlet reaches and gains facial recognition plus pet and vehicle detection once paired with a HomeBase S380. Pick the Reolink Duo 3 WiFi if you can run power to the spot, and the Eufy SoloCam S220 for a sunny wall with no cable at all.

What the differences mean

Power

The Eufy SoloCam S220 runs on a rechargeable battery topped up by its own solar panel, so it needs no cable at all. The Reolink Duo 3 WiFi is plug-in only on 12V, with no battery, which means an outlet or a power run to the mounting spot.

Coverage and resolution

The Reolink Duo 3 WiFi stitches two lenses into a 180 degree horizontal view in 4K, enough for a whole driveway or the front of a house. The Eufy SoloCam S220 records 2K with a 135 degree diagonal view, which covers a porch or a side gate.

Recording

With a constant power supply, the Reolink Duo 3 WiFi keeps a 24/7 video history on a microSD card of up to 512GB and streams over RTSP to an NVR or Home Assistant. The Eufy SoloCam S220 saves motion events to 8GB of built-in storage, has no microSD slot or RTSP, and cannot use eufy's cloud.

Night vision and deterrence

The Reolink Duo 3 WiFi adds color night vision and a spotlight that switches on with the siren when someone is detected. The Eufy SoloCam S220 sees in black and white at night and has no light, only a 75dB siren.

Network

The Reolink Duo 3 WiFi joins 2.4 or 5 GHz Wi-Fi and also has an Ethernet port. The Eufy SoloCam S220 is 2.4 GHz only, so its signal at the mounting spot matters more.

What owners say

Owners of both cameras lead with the same relief: no subscription to keep their clips. From there they talk about different things. Reolink Duo 3 WiFi owners single out the panoramic image, crisp and almost free of fish-eye, a Wi-Fi link they call stable even at distance and a bright spotlight at night, while they warn that the ultra-wide view is wasted in a small room, that distant subjects get grainy when zoomed and that first setup sometimes needs a wired connection before switching to Wi-Fi. Eufy SoloCam S220 owners praise an install of a few minutes and a solar panel that keeps the battery near full in a sunny spot, but those in shaded yards or northern winters still recharge it by cable, and motion detection draws mixed reports, from missed passers-by to alerts set off by leaves.

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.
