2026 verdict
Subscription cloud or local recording? The Reolink Duo 3 WiFi is the better outdoor camera by a wide margin, recording 4K across 180 degrees to a microSD card with no plan required.
It adds color night vision, a spotlight, RTSP, dual-band Wi-Fi plus Ethernet, motion and privacy zones, animal and vehicle detection and a 2-year warranty against 1 year. The Blink Outdoor 4 is the more affordable and better reviewed camera, and it is wire-free: its battery is rated for 24 months, so it mounts anywhere in minutes. It records 1080p in black and white at night, and its video history and person alerts need a Blink subscription. Choose the Reolink Duo 3 WiFi for a wall with power and serious coverage, and the Blink Outdoor 4 for cheap, cable-free cameras in an Alexa home.

What the differences mean
Power
The Blink Outdoor 4 runs on batteries rated for 24 months and needs no cable at all. The Reolink Duo 3 WiFi needs a 12V outlet, which limits where it can go but means it never needs new batteries.
Recording and fees
The Reolink Duo 3 WiFi records locally to microSD or an NVR, including 24/7, with no plan, and offers RTSP. The Blink Outdoor 4 needs a Blink subscription for video history and person detection, and live view is limited to a few minutes without one.
Image
The Reolink Duo 3 WiFi records 4K across 180 degrees with color night vision and a spotlight. The Blink Outdoor 4 records 1080p across 143 degrees diagonal and sees in black and white at night, fine for general monitoring but not for faces at a distance.
Network
The Reolink Duo 3 WiFi joins 2.4 or 5 GHz Wi-Fi or Ethernet. The Blink Outdoor 4 is 2.4 GHz only and works through Blink's sync module.
Smart home
The Blink Outdoor 4 works with Alexa and Home Assistant. The Reolink Duo 3 WiFi works with Google Home and Home Assistant but not Alexa.

What owners say
Owners of both cameras say setup was quick and that motion alerts cut down on false alarms, and both groups mention buying several units at once. Blink Outdoor 4 owners single out a battery that really does last for years, a tool-free install and a discreet body that adds easily to a Blink system; they complain that person detection and saved video sit behind a subscription, that the bundled sync module has no local storage slot, and that the system can lock up after a power cut or an update. Reolink Duo 3 WiFi owners praise a 180 degree view with almost no fish-eye, a stable Wi-Fi 6 link and local recording with no fee, while warning about grainy distant zoom and a first setup that sometimes has to start over Ethernet.
