The Reolink Duo 3 PoE is a 16MP outdoor security camera with two 4K image sensors stitched into a single 180-degree panoramic view, designed to replace two single-lens cameras with one mounting point. The camera runs on Power over Ethernet, with a single Cat5e or Cat6 cable handling both power and network data. Smart Detection sorts movement into person, vehicle, and animal categories. The Duo 3 PoE also has an IP67 weatherproof rating for outdoor installations in rain, snow, or sun.

A dual-lens 4K security camera to improve home surveillance
The Duo 3 PoE uses two 4K image sensors mounted side by side, with a dual-image stitching algorithm merging the feeds into a 180-degree panoramic view at 16MP total resolution (7680 x 2160). The combined image keeps a 4-core SoC working on the stitching in real time, so there’s no visible seam between the two halves of the field of view. Plus, the panoramic format lets one Duo 3 PoE monitor your full backyard, driveway, or warehouse loading area instead of needing two cameras for the same area.
The F1.6 aperture and 1/2.7″ CMOS sensor pair with 6 infrared LED lights for night vision up to 100 feet. Built-in spotlights add color night vision when motion triggers the lights, useful for catching faces, license plates, or vehicle colors on your property in low-light areas. Smart Detection also separates real movement (people, vehicles, animals) from background noise like leaves blowing or rain falling, which cuts down on the false-alert flood that older motion detection cameras generate.
