Swann NVR 47400 issue

[paulcullingworth 0]

Please advise, I've started off with one issue and compounded it.

I have a NVR 47400  with four number cameras around the house and the issue is one of the cameras isn't showing on the surveillance screen (computer)

The issue is at the NVR, one of the four channel inputs is not showing any lights at the cable entry ( other three cable connections showing two lights per connection.)

I have swapped cameras over and the camera and cabling is ok.

I did a re-boot and now it's saying there is a login problem.

The details I am using are what I have always used but cannot get past  this login issue, so ;

Is there a way forward with login? and when the lights are out on the effected camera channel to NVR. is it terminal?

Thanks for any assistance with this compounded problem

Your DVR system or NVR system has a green and red light flashing. Your security camera is not in color, not clear, or not responding.
