QUESTIONS

About the diagnosis

Why does the lift camera work when the lift is stopped but not when it moves?

The fault is in the moving part: a cracked conductor in a solid-core cable, a loose connector, or a voltage drop under load. Replace the moving section with a flat stranded cable and re-terminate.

How accurate is the diagnosis?

It ranks the common causes from your answers. It cannot see the lift well, so treat the result as the first thing to test, not a verdict. The tests listed take minutes.

What if the fault happens even when the lift is parked?

Then it is probably not the travelling cable. Check the fixed section first: the punch-down at the junction box, the switch port, the NVR.
