What Reolink Argus 4 Pro owners think

Most owners who stick with the Argus 4 Pro call it a dependable, well-built camera with standout night color vision and image clarity, and several report the battery barely dips when the solar panel is doing its job. A meaningful minority describe the opposite battery experience, with charges dying in a few days or draining outright even with solar attached. Recording and detection lag is the other recurring complaint: motion gets picked up but the clip starts late, notifications go missing, or an event never records at all. A smaller group also flags dropped connections and the camera failing to work locally when the internet is out.
