+ \\
+=====Introduction=====
+The WebCam on Server provides the captured images to all connected clients.\\
+Supported clients:
+  * __**[[:english#rocview|Rocview]]**__
+  * __**[[:rocweb:rocweb-en|Rocweb]]**__
+The captured WebCam image should be as small as possible to save bandwidth. This is especially important in case of connected mobile clients.\\
+ \\
+=====Setup=====
+====Text Object====
+{{:text:webcam-server-setup-en.png}}\\
+  * Refresh must be set to zero
+  * The **WebCam** option must be activated
+  * The new captured image will be searched in the __**[[:rocrailini-gen-en#image_path|Image Path]]**__
+ \\
+====Action====
+{{:text:webcam-server-action-en.png}}\\
+The action calls an external __**[[#capture_script|Capture Script]]**__ for capturing a new snapshot image from the WebCam.\\
+The **Asynchrone** option should be disabled for this action.\\
+ \\
+====Action Control====
+{{:text:webcam-action-control-en.png}}\\
+This action will be called every second, fixed, with the state set to "**webcam**".\\
+ \\
+====Capture Script====
+The script must provide an image in JPEG format and should be as small as possible and **must be smaller then 100kB**.\\
+===macOS===
+The **wacaw** --CIF option will generate a small image of 352 X 288. ([[https://en.wikipedia.org/wiki/Common_Intermediate_Format|Common Intermediate Format]])\\
+<code bash>
