Recently purchased an hik nvr 7600 series. I don't not have this plugged into a network right now but I have hooked the nvr to a monitor to start the setup wizard. I cannot go any further in the setup process because it's asking for an administrator password. Now I saw post here before that state the default password is "12345" but that doesn't seem to be working. Is there a reason that the hik default password would not work fresh out of the box ?
