2026 verdict
One cable or two? The Reolink Duo 3 WiFi edges out its PoE twin as the better reviewed of these two 180 degree cameras, and the one that does not need an Ethernet run.
It connects on dual-band Wi-Fi with an Ethernet port as a fallback, is 58g lighter and adds Reolink cloud as an optional paid backup. The Reolink Duo 3 PoE is the cheaper version and takes power and data over a single PoE cable, which is the steadier connection for a camera streaming a 180 degree 4K panorama all day. Everything else matches: the same housing and 180 by 55 degree view, IP67, microSD and 24/7 recording, RTSP, spotlight, siren, and Google Home and Home Assistant support. Choose the Reolink Duo 3 WiFi where cabling is hard, and the Reolink Duo 3 PoE if you can pull Ethernet.

What the differences mean
Connection and power
The Reolink Duo 3 PoE runs on one Ethernet cable that carries power and data, with no Wi-Fi. The Reolink Duo 3 WiFi connects on 2.4 or 5 GHz Wi-Fi, keeps an Ethernet port as an option and plugs into a 12V adapter, so it needs an outlet rather than a network cable.
Reliability of the stream
A wired PoE link is immune to Wi-Fi congestion and range, which matters for a camera sending a high-resolution panorama around the clock. The Reolink Duo 3 WiFi's dual-band radio is strong, but its signal still depends on where your router is.
Cloud option
The Reolink Duo 3 WiFi can use Reolink cloud with a subscription. The Reolink Duo 3 PoE has no cloud option at all and records only to microSD or an NVR.
What is identical
Same 195 x 103 x 56 mm housing, 180 degree view, IP67, 4K color night vision, spotlight, siren, RTSP, 2-year warranty and the same platforms. Picking between them is only about the cable.
Which one to buy if
- running an Ethernet cable to the spot is hard
The Reolink Duo 3 WiFi only needs an outlet and a Wi-Fi signal.
- you are wiring a new house or already have a PoE switch
The Reolink Duo 3 PoE takes power and data over one cable and costs less.
- the camera sits far from the router
A PoE cable delivers a steady stream at any distance Wi-Fi might struggle with.
- you want an off-site cloud backup
Only the Reolink Duo 3 WiFi offers Reolink cloud storage, as a paid option.

What owners say
Owners of both Duo 3 versions describe the same camera: a crisp 16MP image stitched into a 180 degree view that replaces two cameras, good color night vision, reliable person, vehicle and animal detection and recording with no subscription. Where they differ is the connection. Reolink Duo 3 PoE owners praise a PoE link that stays up even in high winds and smooth integration with NVRs and Blue Iris, and they grumble about a fiddly mount that can leave a hole open to rain and RTSP and ONVIF switched off by default. Reolink Duo 3 WiFi owners single out a Wi-Fi 6 link that holds at distance, but several had to set it up over Ethernet first, and they mention it running warm in the heat and grainy distant zoom.
