Eufy 4G Camera S230 vs Reolink Duo 2V PoE

The Reolink Duo 2V PoE is the stronger camera, with a 180 degree 4K dual-lens view, color night vision, PoE reliability, RTSP, privacy zones, a higher rating and a 2 year warranty. The Eufy 4G Camera S230 is the pick when there is no Wi-Fi or power, thanks to its 4G LTE and GPS.

Power and connectivity. The Reolink Duo 2V PoE is a wired PoE camera that covers a 180 degree 4K panorama, while the Eufy 4G Camera S230 is a battery camera on cellular 4G LTE with GPS. One needs an Ethernet run but sees far more; the other needs nothing but a signal.

The Eufy 4G Camera S230 can. It is battery-powered with 4G LTE and GPS, so it needs neither a network nor a wired outlet. The Reolink Duo 2V PoE is Ethernet-only and must reach a PoE switch or injector, which rules out truly off-grid spots.

The Reolink Duo 2V PoE does. Its two lenses stitch a 180 degree panorama in 4K, replacing two cameras, while the Eufy 4G Camera S230 records 2K from a single fixed 120 degree lens. For wide, sharp coverage the Reolink is well ahead.

Buy the Eufy 4G Camera S230 if you need a cellular, GPS-equipped camera for a location with no Wi-Fi or power, such as a remote cabin or field. It is the go-anywhere option in this pair and the more affordable one.

Buy the Reolink Duo 2V PoE if you can run Ethernet and want one rugged camera to cover a wide 180 degree area in 4K with no monthly fee. It is ideal for prosumers and Blue Iris or Home Assistant users who value RTSP and PoE reliability.
