Finally have my cameras working on the nvr after 2 days. My only problem now is when I uncheck the dchp box and apply I get an error. Operation failed, IPv4 addresses of device and internal NIC conflict. Please set again. The IPv4 address is 192.168.254.64 The internal NIC is 192.168.254.1 I don't know which one to change or what to change it to.
