The **Devices** node is displayed under the** Local Vicon System** node when licensed additional devices (that is, connected devices that are not cameras or connectivity devices) are connected to the Vicon system. The **Devices** node lists each additional type of device that is connected to your Vicon system.

You can only use an additional device if you have the required license. To check your current licensing options, from the **Help** menu, click **About Vicon Tracker** and in the window, click the **Feature Details** button. After a few seconds, the currently licensed options are listed. To change your licensing options, contact [Vicon Support](mailto:support@vicon.com).

Depending on the type of additional licenses you are using with Tracker and your Vicon system, it may contain one or more of the following additional devices:

- Analog device such as accelerometers (see [Set up analog devices](https://vicon-help.atlassian.net/wiki/spaces/Tracker310/pages/13926938))
- Eye tracking devices (see [About eye tracking](https://vicon-help.atlassian.net/wiki/spaces/Tracker310/pages/13930628))
