Hi I just got a Hikvision camera DS-2CD2387G2-LSU/SL and I have connected using a TP-Link injector and when I look at my ASUS router it shows the port the injector is connected to as 'connection can be improved in orange' if I connect the camera to a switch I don't get this message and the port shows in green Just wondering if the injector is faulty after having it for so many years Also I would like to know if is there any difference between the using the injector or using the switch? I found the answer myself, the PoE injector I have is not Gigabite capable, it's only 100 mb and My ASUS router LAN port is 1gb I probably need to get a Gigabite Poe Injector although no single IP camera will use more than the 100Mbps capability of this injector Correct me if I'm wrong Thank you
