Dual 4K sensors for 16MP panoramic coverage

The Reolink Duo 3 WiFi 2-Pack combines two outdoor bullet cameras, each using dual 4K image sensors stitched into a single 16MP 180° view. Integrated spotlights and IR LEDs provide colour or infrared night vision. IP67-rated housings withstand rain and dust. Smart detection distinguishes people, vehicles and animals, triggering a built-in siren and real-time alerts. Footage stores locally on up to 512GB microSD cards, FTP/NAS, Reolink Home Hub or compatible NVRs without mandatory cloud fees.

Verify Wi-Fi 6 router and mounting surface

Both cameras connect wirelessly using IEEE 802.11 ac/ax on 2.4 GHz and 5 GHz bands, so a Wi-Fi 6 router or access point is needed for the advertised stability and speed. Each unit requires a nearby mains socket for its power plug. Choose a wall or ceiling location that can support the camera weight and allows the external antennas to orient freely. Ensure the mounting surface is solid enough for screws and that the 2.8 mm lens field of view covers the desired zone without obstructions.

Spotlights, siren and local storage replace

Eight integrated spotlights enable full-colour night recording, while the IR mode offers a stealthier alternative. Motion Track overlays an object’s path across time in one frame, simplifying event review. The onboard siren and spotlight alarm activate automatically on detection, providing active deterrence. Two-way audio lets you speak to visitors remotely. MicroSD cards up to 512GB, FTP/NAS, Reolink Home Hub and NVR recording keep footage under your control with no recurring charges.

Questions about this item

What comes in the box and do I need to buy a microSD card separately?

The 2-pack includes two 16MP Duo 3 WiFi cameras with external antennas and mounting hardware for wall or ceiling installation. A microSD card up to 512GB is supported but not included, so you must purchase one separately if you want local recording.

Should I choose the 2.4 GHz or 5 GHz band for Wi-Fi 6 connectivity?

Both 2.4 GHz and 5 GHz bands are supported under Wi-Fi 6 (IEEE 802.11 ax). Use 5 GHz for higher throughput at shorter range; switch to 2.4 GHz if the camera is farther from the router or passes through walls.

What does the 16MP 180° panorama look like in practice?

Dual 4K sensors with 2.8 mm lenses are stitched into a single 180° view, delivering 16MP ultra-clear footage. Motion Track overlays the target's full path with timestamps in one frame, and eight spotlights plus an F1.6 aperture enable color night vision.
