O.P.
I have 2 x Hikvision cameras and NVR. Out of the blue the No Network Video sign has popped up.
I set the NVR to alternate between each camera and when the camera changes between each other the live image appears for about 20 seconds then No Network Video appears again.
Any suggestions on how to get back to a constant live image?

I would start with checking the cable runs to the cameras to ensure they have not become damaged. I would next check the power supply as "short" working before stopping is a sign of failing power supplies or increased resistances in the cabling (ie: damaged).
