2026 verdict
Without an Ethernet run, the Reolink Duo 3 WiFi is the better buy of this pair, and it also beats the Reolink OMVI 3i PoE on price, wireless connectivity and storage options.
The Reolink Duo 3 WiFi is the wireless take on Reolink's 16MP panoramic camera, plug-in powered with no battery and connected over dual-band Wi-Fi 6, with an Ethernet port as a backup. The Reolink OMVI 3i PoE is the wired counterpart, running on one Power-over-Ethernet cable and swapping the fixed lens pair for a 10MP panorama plus a 4K tracking lens. Both shoot 4K-grade wide video, record to a microSD card with no subscription and work with Google Home and Home Assistant rather than Alexa or HomeKit. Pick the Reolink Duo 3 WiFi when no cable can be run, and the Reolink OMVI 3i PoE when you want the stability of PoE and a lens that follows movement.

What the differences mean
Power and connection
The Reolink Duo 3 WiFi connects over dual-band 2.4 and 5GHz Wi-Fi 6 and is powered by a plug-in 12V adapter, with an Ethernet port as a fallback. The Reolink OMVI 3i PoE instead draws power and data from one PoE cable, which is more stable but needs a wired run.
Lens design
The Reolink Duo 3 WiFi stitches two fixed 16MP lenses into one 180 degree panorama. The Reolink OMVI 3i PoE adds a third, 4K pan-tilt lens that tracks movement, so it can follow a subject the fixed view would lose.
Setup
The Reolink Duo 3 WiFi can be slow to get onto Wi-Fi the first time, and owners suggest wiring it once to configure it. The Reolink OMVI 3i PoE also needs the app and an internet connection for first setup, but its connection is then fixed by the cable.
Indoor and outdoor use
The 180 degree lens on the Reolink Duo 3 WiFi is built for wide outdoor scenes and is wasted in a small room. The same is true of the Reolink OMVI 3i PoE, so both belong outside covering a yard or driveway.
Weather rating
The Reolink Duo 3 WiFi is rated IP67 and the Reolink OMVI 3i PoE IP66, so the wireless model is the slightly more weather-proof of the two, though neither ships a waterproof Ethernet connector.
Which one to buy if
- you cannot run an Ethernet cable to the spot
The Reolink Duo 3 WiFi connects over Wi-Fi 6 and only needs a power outlet.
- you can wire the camera and want rock-solid uptime
The Reolink OMVI 3i PoE draws power and data from one cable, with no wireless link to drop.
- following a moving person or vehicle matters most
The Reolink OMVI 3i PoE adds a tracking pan-tilt lens the Reolink Duo 3 WiFi does not have.
- you want the better value of the two
The Reolink Duo 3 WiFi is the more affordable camera and needs no PoE switch.

What owners say
Owners of both praise the same core: a clean 16MP-grade 180 degree view that shows almost no fish-eye, local storage with no subscription, and a camera that fits neatly into the wider Reolink system. Where they part is the connection. Reolink Duo 3 WiFi owners single out the stable Wi-Fi 6 link even at distance and the fact that plug-in power means no batteries to recharge, but several warn the first Wi-Fi setup is fiddly and needed a wired run to finish, and that distant subjects get grainy when zoomed. Reolink OMVI 3i PoE owners instead talk about the tracking lens, calling the wide shot crisp and the mount solid, while noting that close-up tracking can be slow and jumpy and that notifications need tuning. Both groups flag the same missing platforms, Alexa and Apple HomeKit.
