Glossary
Definitions of loss terms used on screen and in downloads. Colors and filters use the same rules.
Loss levels (Normal · Low · Partial · Recording fault)
Levels are based on how much video was missing in one camera’s time bucket (usually one minute).
Level thresholds
- Normal — no loss in that interval (0%)
- Low loss — minor gaps (more than 0% and under 10%). Example: under 6 seconds missing in a 1-minute bucket
- Partial loss — noticeable gaps (10% up to under 70%). Example: 6– under 42 seconds in a minute
- Recording fault — severe loss (70% or more). Example: 42+ seconds missing in a minute
Good to know
- Loss means video was missing or interrupted during time that should have been recorded.
- The Partial filter focuses on milder intervals (including low loss), below recording-fault level.
- The Recording fault filter shows 70%+ intervals only. (Optionally, minutes with no collected data may also count as recording fault.)

Metrics that often appear in camera detail and Excel.
Metric definitions
- Loss intervals (minutes) — count of 1-minute buckets with loss in the query period (a minute count, not necessarily “continuous blocks”).
- Max loss rate — the worst minute’s loss ratio for that camera in the period (0–100% or 0–1). Example: 80% means 80% of that minute was missing.
- Total loss seconds — sum of missing video time in the period.
- Low / Partial / Recording-fault (minutes) — how many minutes fell into each level above.
- First / Last collected — when data for this camera first/last arrived (may differ from the query period).
“Loss intervals” list in detail view
The right-hand detail panel may group continuous loss into from–to ranges.
That can look different from Excel’s loss intervals (minutes) count — use the list for time spans, and the number for how many minutes had loss.
