# originalDetection

The original detection based on the fixed detection track.

## Declaration

```swift
var originalDetection: CNDetection? { get }
```

## Discussion

Discussion This is the way to determine the time and bounds from which the fixed focus originated. This detection isn’t part of the detection track and has a different detection ID or none. important: To get a detection from the fixed detection track, use detectionAtOrBeforeTime: instead, which returns a properly time-stamped detection.
