Hi, so i got both device listed in my post and they did not work ...
so I went to buy this guy:
TL-POE150S
And it works! at least the RGB example 😃 - I have my OAK-D POE connected on one of the 2 ETH on my motherboard (which also has wifi) - I got it working by manually configuring the IPV4 settings:

My plan is to connect the camera to an NVIDIA TX2 battery-powered .. I'll do some test to see how it behaves .. for the time being, I will test some code (opening another topic for my use case soon)
