Hello, I have a problem when I want to connect the dahua full color cameras to the NVR nvr-5432-16p, the nvr recognizes the connection, allows the device to be loaded but does not give IMAGE/VIDEO, we tried assigning an ip within the network range and still not It gives an image, then we try with the factory settings and neither... the only thing left is to see if the problem does not come from the firmware of the nvr since it has a firmware Version: 2.616.0000, and it is already a bit old for the new equipment... so my question is if the nvr changed it to what version would it support? Or do you have any suggestions for a solution?
