My card is GV 1120A PCI E with software ver 8.5.3 and I planning to replace 4 analog with 4 IP camera. I m suppose to buy the GV-EFD2100-0F 2 MP but the GV-EBD4700 4 MP caught my eye which is cheaper. Is my card compatible with GV-EBD4700? sorry for asking stupid question I just cant believe that the 4 MP is cheaper than 2 MP and I m worried that it might be only compatible with newer card this year(if any).
tnx
