CameraServer
============

**Inherits:** :ref:`Object<class_Object>`

Server keeping track of different cameras accessible in Godot.

.. rst-class:: classref-introduction-group

Description
-----------

The **CameraServer** keeps track of different cameras accessible in Godot. These are external cameras such as webcams or the cameras on your phone.

It is notably used to provide AR modules with a video feed from the camera.

\ **Note:** This class is currently only implemented on Linux, macOS, and iOS, on other platforms no :ref:`CameraFeed<class_CameraFeed>`\ s will be available. To get a :ref:`CameraFeed<class_CameraFeed>` on iOS, the camera plugin from `godot-ios-plugins <https://github.com/godotengine/godot-ios-plugins>`__ is required.
