# Sensor Specs: Traffic (Vion G5)

This describes the measurement method and definition for each sensor.

## Vion G5

Measurable KPIs (available KPIs vary by your contracted options)

-   Traffic
    
-   Attributes
    
-   Dwell Time
    
-   Re:ID Support
    

\*What is Re:ID? Re:ID is image processing that assigns an ID to a person so that the same person, identified across multiple cameras or within the same measurement view using features like appearance, build, and clothing, can be excluded from duplicate counting.

## Measurement Method

### Traffic

The camera captures multiple images of visitors and assigns a Re:ID.

If the visitor is a customer, traffic count increases when they cross the count line within the measurement range.

\*If the same visitor crosses the count line multiple times, Re:ID is used to exclude the duplicate count.

If the visitor is a staff member, they are excluded from the traffic count when they cross the count line.

\*Crossing the count line 3+ times, or staying in the store 6+ hours, will also result in exclusion as staff. This definition cannot be customized.

### Attributes

Age group and gender are calculated using the appearance, build, clothing, and other features of anyone counted under the traffic definition.

### Dwell Time

Dwell time is calculated based on count-line entries/exits for anyone counted under the traffic definition, using their appearance, build, clothing, and other features.
