Investigate a missed camera event Prepared 22 October 2026 by NightMarshal Trace a missed event through capture, detection, event delivery, review and notification. Preserve the original evidence and configuration before changing sensitivity; a missing notification does not identify which stage failed. Instructions 1. Preserve footage and configuration references. 2. Find the first stage without the expected evidence. 3. Retest safely and document the residual limitation. Open the blank CSV in a spreadsheet app; add one row per item. Use Pending for unknowns and N/A only where a field truly does not apply. Review the separate example CSV; all example values are fictional. Keep completed sheets private. Do not include passwords, access codes, personal contacts, footage links or camera stream URLs. No input is collected by these downloads. Fields Incident reference Footage present Event created Provider received Reviewed Contact acknowledged First gap Fictional example Fictional review: video exists and the recorder created an event, but the monitoring system never received it. The investigation moves to event delivery rather than widening the detection zone. Limits Do not infer intent, identity or a guaranteed future detection rate from one event.
