# transportControlsSupported

A Boolean value that indicates whether the device supports transport control commands.

```
var transportControlsSupported: Bool { get }
```

## Discussion

For devices with transport controls, such as AVC tape-based camcorders or pro capture devices with RS422 deck control, the value of this property is <doc://com.apple.documentation/documentation/Swift/true>. If transport controls aren’t supported, none of the associated transport control methods and properties are available to the device.

This property is key-value observable.
