Keep the video stream settings, segment duration, amount of data written, time range and playback results from the single-stream trial. Use them as the baseline for extended validation. Before adding video streams or extending retention, agree on the workload, disk conditions, number of playback clients and acceptable durations of gaps in the recorded video.
Which variable should change first?
One option is to record more video streams for the same test duration. Check the files, index and playback for each stream. Then extend the run at the target stream count and observe writes, cleanup and concurrent searches. When recording shares resources with inference or live preview, record load and failures for the target combination.
When can a result be marked as passed?
Record each result against the acceptance criteria for its workload. Check recovery after stream loss, service restart and low disk space. Preserve original anomalies, the applicable decision rule and pending tests. A successful test result applies to the documented duration, number of video streams, stream settings and storage conditions. Mark other combinations as pending verification.
