Which one to buy if

What owners say

Blink Outdoor 4 owners like how discreet and compact it is next to other outdoor cameras, and many run it alongside Blink doorbells and floodlights in one system. Their complaints include no on-screen date and time stamp on clips, and that Alexa and IFTTT are the only smart-home platforms it reaches on its own. Reolink Duo 2V PoE owners say the wired connection holds up even in high wind, and they like how cleanly it slots into a Reolink NVR alongside other cameras. Their complaints are mostly about the dome-cover screws, which strip easily, and that there is no pan-tilt, so aiming is fixed once it is mounted.
