Good morning would greatly appreciate if someone could help me. Recently i bough 2 additional cameras for my 8 Ch system, Floureon H.264. I bought AHD Kmoon cameras. When i connected the cameras, none of them seems to be working. I don't think its a fault in the camera.... it might more seem a problem with the system. On the screen i am just having a screen saying NO VIDEO. Can someone help pleaseee. Thanks so much
