Happy new year kimchiGUN, Yes, all cameras are plugged in and I have re started and done a factory reset? Still the same. Cameras not loading 1 has infa red lights on at night, canle in harddrive flashing but no picture loading.

The other 1 has no flashing lights where cable go into and with no infa red lights on at night.

I have a RLN8-410 with 8 ports, 4 cameras working showing previewing with 4 offline on the menu. 2 more plugged in coming up offline, any way to get cameras working please.
