# factors

The set of underlying causes for the system pressure level.

```
var factors: AVCaptureDevice.SystemPressureState.Factors { get }
```

## Discussion

Increased system pressure may be due to one or more contributing causes; this set provides additional details for the overall performance characterization reported by the [`level`](/documentation/AVFoundation/AVCaptureDevice/SystemPressureState-swift.class/level-swift.property) property.

When the system pressure level is high, you can use this information to choose how to mitigate the issue. For example, you can reduce high system pressure due to [`depthModuleTemperature`](/documentation/AVFoundation/AVCaptureDevice/SystemPressureState-swift.class/Factors-swift.struct/depthModuleTemperature) (on a [`builtInTrueDepthCamera`](/documentation/AVFoundation/AVCaptureDevice/DeviceType-swift.struct/builtInTrueDepthCamera) device) by limiting the depth capture frame rate.
