Blink Outdoor 4 vs Reolink Duo 3 PoE

For most buyers the Reolink Duo 3 PoE is the better camera: 16MP dual-lens 180 degree coverage in 4K, color night vision, reliable PoE, RTSP/ONVIF, subscription-free local recording, a 2 year warranty and a higher rating. The Blink Outdoor 4 is the pick only if you specifically want a cheap, wire-free Alexa camera.

Resolution, coverage and power. The Reolink Duo 3 PoE is a wired 16MP camera whose stitched 180 degree view replaces two cameras in 4K, while the Blink Outdoor 4 is a battery-powered 1080p camera with a single 143 degree lens. Reolink needs a cable but sees far more, in far more detail.

The Reolink Duo 3 PoE records 24/7 to microSD or an NVR with no subscription and offers RTSP/ONVIF. The Blink Outdoor 4 stores to the cloud but gates person detection and video history behind a Blink plan, so Reolink is the one that avoids ongoing costs.

Yes, the Blink Outdoor 4. Being fully wire-free with a battery rated up to 2 years, it mounts wherever you like. The Reolink Duo 3 PoE is Ethernet-only and must reach a PoE switch or injector, trading placement freedom for a very stable connection and continuous recording.

Buy the Blink Outdoor 4 if you want an inexpensive, wireless outdoor camera that goes up in minutes, lasts years on batteries and works with Alexa. It fits renters and simple homes where 1080p and a subscription for saved clips are fine.

Buy the Reolink Duo 3 PoE if you can run Ethernet and want the sharpest wide coverage from one camera, in 16MP 4K, with no monthly fee. It suits NVR owners and self-hosted Blue Iris or AgentDVR setups that want RTSP/ONVIF and local control.
