- Ambient threshold
- The illuminance value at which a lighting profile transitions between states. Thresholds are set per area and reviewed periodically.
- Calibration window
- A defined period during which a model is updated against observed conditions. Calibration windows are scheduled annually and published in advance of the work.
- Continuous coverage
- A condition in which no point within a defined area falls outside the sensing envelope of at least one active unit.
- Cycle
- The internal accounting period used for telemetry. Cycles are not aligned to calendar intervals.
- Dwell time
- The mean duration for which a person remains stationary within a monitored area. Elevated dwell times may indicate a requirement for review.
- Interchange
- A location at which two or more networks share infrastructure.
- Junction
- A location at which the network maintains one or more units. Junctions are numbered internally and are not published.
- Materiality threshold
- The level of impact below which an adjustment does not require notification. See Adjustment and the Threshold of Materiality.
- Reconciliation
- The process by which an unexpected reading is brought into agreement with the model.
- Residual
- The difference between a predicted value and an observed value.
