Factors Affecting Accuracy
- Two people passing through side by side will be counted as one person.
- Holding something with your hand raised or pushing a shopping cart may result in overcounting.
- Walking at speeds greater than 1.5 m/s may result in missed counts.
- When a single person closely follows another (with a distance of less than 20 cm), there is a chance of missing the count.
- Passing close to the node device or passing at an angle may result in reverse counting.
