NOTE: When you update firmware remotely depending on the DVR/firmware
version it may NOT keep the settings. They may reset to default. This means you
won’t be able to access the DVR remotely again if the network settings become
reset. You will either have to set the network settings again at the DVR or have
remote access to a computer on the network.
