Why does video playback matter more than a text log alone?

A text log tells you a stop happened and roughly why the system logged it; video playback shows you what actually happened physically — a jam, a misfeed, an operator action — which is often the difference between guessing at a fix and knowing exactly what to change.

How is this organised on the dashboard?

See Can Cobot and AMR Systems Be Monitored Remotely? for how this same video and event data supports engineers diagnosing faults off-site.

Does this help with recurring faults specifically?

Yes — being able to compare footage across several occurrences of the same fault is exactly what helps identify a root cause instead of repeatedly clearing the same symptom. See How Can Palletiser Performance Be Tracked and Improved?
