# isLowLightVideoNoiseReductionEnabled

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

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

## Discussion

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