Glossary

Site (Installation): A physical infrastructure where sensors are installed. Typically represents a building (e.g., train station, store) or an event.
Zone: A physical area within a site for which metrics are tracked. Zones are hierarchical - for example, a building can have multiple floors, and each floor can have multiple areas.
Passage: A passageway that connects two zones. Used to count people entering and leaving linked zones. Each passage has defined entrance and exit zones.
Cartography: The representation of zones and passages organized in a hierarchical tree structure, essentially mapping out the physical layout of a site in the Technis system.
Devices (sensors): specialized hardware units (mats, cameras or air quality sensors) installed on-site to counting people, objects or record data about the environment.

Metric: a measurement captured by devices on a particular site, in a particular zone or passage. eg. number of visitors inside a space, time spent, or CO₂ levels.
Report: an interactive document that can contain multiple visualizations or accompanying text.
Filter: filters are used to narrow down data that qualifies as a result in a report. For example, you many want to consider only data from a particular site, zone or a passage.
Breakdown: groups the results of your queries in reports by a property, allowing you to examine which properties or groups have significant impact.
Descriptor: additional identifier used to refine data queries, such as gender or age group classifications.
Time grain: the unit of time in which visualization will be displayed in. For example, a visualization with minutely time grain will display data for each minute of a selected time range.
Time range (time span): the range for which the data is being displayed.

Alert rule: an expression of conditions for which an alert should be raised. For example, if the people inside a zone is more than 200.
Alert: happens when an alert rule's condition is satisfied. For example, when the people inside a zone is 201.
Condition: mathematical comparison (smaller, greater, equals) that compares the current measured value of a metric with a predefined threshold.
