It wins on price, solar charging, dual-band Wi-Fi and an optional cloud backup, and its 355 degree pan and 140 degree tilt follow movement across a yard, with Alexa support too. The Reolink Duo 3 PoE is the better reviewed camera and the stronger one wherever Ethernet can reach: a fixed 180 degree dual-lens view recorded 24/7, native RTSP and Home Assistant, and IP67 against IP65. Both record 4K with color night vision, a spotlight and free microSD storage. Pick the Reolink Argus PT Ultra + Solar Panel for a spot with no power, and the Reolink Duo 3 PoE for continuous wired coverage.

What the differences mean

Power

The Reolink Argus PT Ultra + Solar Panel runs on a rechargeable battery charged by its included panel, so it needs no cable at all. The Reolink Duo 3 PoE takes power and data over one Ethernet cable, which means a cable run and a PoE switch or injector.

Recording mode

The Reolink Duo 3 PoE records 24/7. The Reolink Argus PT Ultra + Solar Panel records events and sleeps in between to save power, though it keeps recording through a Wi-Fi or power outage.

Coverage

The Reolink Duo 3 PoE sees a fixed 180 degree panorama at once. The Reolink Argus PT Ultra + Solar Panel sees 90 degrees at a time but pans 355 degrees and tilts 140 degrees to follow movement.

Integrations

The Reolink Duo 3 PoE streams RTSP and works with Home Assistant directly. The Reolink Argus PT Ultra + Solar Panel adds Alexa, but needs a Reolink Home Hub for RTSP and Home Assistant. Both work with Google Home.

What owners say

Owners of both Reolink cameras praise detailed 4K-class video, bright color night vision and recording with no subscription. Reolink Argus PT Ultra + Solar Panel owners report the included panel keeping the battery near full even in winter and like the auto-tracking pan-tilt, while warning that it sleeps between events instead of recording 24/7, that live view has to reload and that RTSP and Home Assistant depend on a Reolink Home Hub some find finicky. Reolink Duo 3 PoE owners single out the 16MP 180 degree view with minimal stitching, a PoE link that stays up in high winds and smooth NVR and Blue Iris integration; their complaints are a fiddly mount that can leave a hole exposed to rain and RTSP and ONVIF switched off by default.
