I purchased the several cams including the IPC-T5449H-ASE-D2 for black friday. After initialing the camera, on the main screen I see "Main Stream", "Substream 1" and "Substream 2". Main Stream and Substream 1 work fine. However when I click Substream 2 it says "Resource is limited, open video failed" and its just a black screen. Anyone know whats going on? Is this a known issue or did I get a bad camera?
