Note 
The NVR automatically defaults to selecting channel 1 when you navigate 
between configuration interfaces. For example, if you have selected channel 3 
on the Motion Detection configuration interface, and then navigate to the 
Channel Name configuration interface, the NVR defaults to channel 1 in the 
Channel selection drop-down. If there is no channel 1 connected, the NVR 
defaults to the first available channel.
