# isHighFrameRateTrackingEnabled

A Boolean value that determines the frequency at which the scanner
updates the geometry of recognized items.

```
@MainActor final let isHighFrameRateTrackingEnabled: Bool
```

## Discussion

If `true`, the scanner
updates the geometry of items more frequently allowing your app to
closely track recognized items. If you don’t track items in the live
video, set this property to
`false`. The default
value is `true`.
