The Eufy 4G Camera S230 solves a narrow problem: it connects over 4G LTE with its own SIM, runs about three months per charge on an IP67 body, keeps around two months of footage on 8GB of built-in memory with no recording subscription, and adds GPS. The Reolink OMVI 3i PoE is far more capable on a wired site, with a 4K 10MP 180 degree panorama, a tracking lens, colour night vision and 24/7 local recording to a microSD card or an NVR. The Eufy 4G Camera S230 is the only one that needs no internet, but its 120 degree view is narrow and it has no RTSP or Wi-Fi. Pick the Eufy 4G Camera S230 for a building site, field or holiday home with no broadband, and the Reolink OMVI 3i PoE for a normal wired property.

What the differences mean

Connection

The Eufy 4G Camera S230 connects over 4G LTE using its own data SIM, so it works with no internet at the site. The Reolink OMVI 3i PoE needs a wired Ethernet line for both power and data, which is faster and free to run but must exist.

Video and coverage

The Eufy 4G Camera S230 records 2K from a fixed 120 degree view. The Reolink OMVI 3i PoE records 4K across a 10MP 180 degree panorama and adds a tracking lens, giving it both a wider and a sharper picture.

Storage

The Eufy 4G Camera S230 holds around two months of clips on 8GB of built-in memory and has no microSD slot. The Reolink OMVI 3i PoE records to a microSD card up to 512GB, an NVR or FTP/NAS, with no cap built into the camera.

GPS

The Eufy 4G Camera S230 has GPS built in, which helps track a unit that moves or could be stolen. The Reolink OMVI 3i PoE has no GPS, since it is expected to stay bolted to one wired spot.

Weather rating

The Eufy 4G Camera S230 is rated IP67, which covers dust and temporary immersion, while the Reolink OMVI 3i PoE is IP66. The Eufy is the slightly more rugged of the two outdoors.

Which one to buy if

What owners say

Owners of the Reolink OMVI 3i PoE describe a camera that rewards a proper installation. They single out the wide 180 degree panoramic view, saying one unit replaces the coverage of two fixed cameras, and they like the way the separate pan-tilt lens swings in to follow a person or vehicle, with several long-time Reolink users calling the pan and tilt smooth and the mount an improvement on their older models. Home Assistant compatibility and the fully local, subscription-free recording come up again and again as reasons they chose it. Their cautions are that close-up tracking can look slow and jumpy, that notifications arrive heavy by default and need tuning, and that the camera supports Google Home and Home Assistant but not Alexa, Apple HomeKit, SmartThings or Matter.
