What the differences mean

PoE versus a cell radio

The Reolink Duo 2V PoE is Power over Ethernet only. It has no Wi-Fi and no battery. The Eufy 4G Camera S230 is the opposite: 4G LTE, no 2.4 GHz Wi-Fi, no Ethernet and no PoE, on a battery rated for 3 months with no solar charging. One needs a cable to the switch. The other needs a cell signal and a SIM.

Coverage and resolution

The Reolink Duo 2V PoE is 4K with a 180 degree horizontal view, color night vision and a light. The Eufy 4G Camera S230 is 2K with color night vision and a light, and a 120 degree diagonal view. The Reolink is the wide camera. The Eufy watches a narrower patch.

How footage is kept

The Reolink Duo 2V PoE records 24/7 to microSD, lists no cloud storage, and supports RTSP. The Eufy 4G Camera S230 stores video on 8 GB inside the camera, has no cloud storage, no microSD slot, no 24/7 history and no RTSP. It can keep recording when the site has no network, because the clips are on the camera.

Detection and GPS

The Reolink Duo 2V PoE detects people, animals and vehicles. The Eufy 4G Camera S230 detects people, not animals or vehicles, and it adds GPS, which the Reolink does not. The Reolink works with Google Home and Home Assistant, not Alexa. The Eufy works with Alexa, Google Home and Home Assistant. Neither supports Apple Home.

Which one to buy if

What owners say

Reolink Duo 2V PoE owners keep coming back to coverage: one stitched view instead of two cameras on a porch, a yard or a small warehouse, with 4K that stays sharp day and night and a PoE run they describe as dull in the best way. People, vehicle and animal detection is what they credit for fewer useless clips, and local microSD or NVR storage is why they say there is no monthly recording fee. The complaints are mechanical. The dome screws strip easily, the spotlight is not as bright as they hoped, digital zoom will not read a distant plate, and one owner reported water inside despite the IP67 rating.

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.
