Which observation helps to find the cause? · warehouse
Fix camera malfunction focuses on image, viewing back, storage status, clock and physical assembly. Note when the problem started, which components were affected, and what changed shortly before that. Check the chain in sections and record where the operation is still present. Repeat the situation in which the error occurred after repair; a restart alone without a follow-up test provides insufficient certainty. We complete the check against a control overview with tested features, observed deviations and agreed recovery.
