Hi RyanLee ,
We apologize for this issue, please contact our Ops team and we will send a replacement unit. We would love to also get the faulty OAK camera to our offices for further investigation, as I haven't heard about thermal issues on OAK POE models yet.
Regarding 1080P resolution - could you share further data? Perhaps debug mode enabled on different resolutions - what temperature does sensor reach in, say, 3min, 5min, 10min, 15min, 30min.. at different resolutions? I would be really interested to know those, as perhaps it's something with firmware as well, not a faulty HW (heat dissipation).
