I bought the NVR16-7200 from Costco that came with 2 varifocals and 6 bullet cameras. When I first got the system I made sure each camera was working and each port. A few weeks later I am setting up the system and only the 2 varifocals and 2 bullet cameras are being connected and showing video. The other 4 bullet are being powered when I connect it to the NVR since the infrared light is coming on but there is no connection being made to the NVR. I tried connecting it directly to my laptop and the same thing is happening. I tried different ports and different cables that work with the cameras that are being connected. Why its baffling, is why will they connect and show video before and not connect again (no connection lights on the port), And why receive power and not connect. I also tried resetting the cameras but nothing. Really hoping that the cameras aren't faulty. Can anyone please help.
