I'm new at IP Cam. This is my first experience. I recently bought this IPC-HDW4431C-A based on everyone's recommendations on this thread. I can't get my network to recognize it. I have the Dahua connected to TL-PoE150S and the TL-PoE150S to my switch or router. The green light is on TL-PoE150S. However, the light is orange on my switch. That means there's no internet connection or communication between the switch to the Dahua. Any ideas or help would be appreciated.
