# isLowLightVideoNoiseReductionEnabled

Indicates whether low light video noise reduction is enabled for the current session.

## Declaration

```swift
var isLowLightVideoNoiseReductionEnabled: Bool { get set }
```

## Discussion

Discussion A BOOL indicating whether low light video noise reduction is enabled on the connection. To set this property directly, first set automaticallyEnablesLowLightVideoNoiseReduction to false; setting this property while automaticallyEnablesLowLightVideoNoiseReduction is true throws an NSInvalidArgumentException. This property may only be set to true if the connection’s isLowLightVideoNoiseReductionSupported property returns true, otherwise an NSInvalidArgumentException is thrown. This property is key-value observable.
