I have the EXACT same problem.
1 Reolink Doorbell POE
2 DUO3 POE
New installation. Router, POE Switch (TL-SG1005P) with just the 3 cameras plugged.
Every day at aprox 18-20h, one camera, or the other, or first one then the 2 of the DUOS (the dorbell has always run smoothly) goes down and doen't recover until i power cycle everything.
Cat7 very good quality cable and RJ45 terminations. It can run for hours without problem, both cameras. One cable is 30m long, the other just 7m.
What is happening??
