 # Addon
 
 ## What is the difference between Camera.play and Camera.showVideo?
 
+> **The Camera Add-on has been removed since Dynamic Web TWAIN [18.1](_articles/info/schedule/deprecated.md#181).** An alternative replacement for this module is [Mobile Document Scanner](https://www.dynamsoft.com/use-cases/mobile-document-scanner/).
+
 `Camera.showVideo` is a built-in feature to handle camera capturing, prospective adjusting, etc. It supports two available modes: document and picture.
 
 `Camera.play` is a more specific API for starting streaming video from the current camera.
 
 Note that these two APIs cannot be mixed with each other.

 # Capture/Image Source
 
 ## Can I import existing images or PDF documents using the Dynamic Web TWAIN SDK?
 
-Yes, Dynamic Web TWAIN supports loading PNG, JPG, BMP, image-only PDF, and TIFF files. But if you need to support text-based PDF files, you also require the <a href="https://www.dynamsoft.com/web-twain/pdf-to-image-javascript/" target="_blank">PDF Rasterizer Addon</a>. See more [here](/_articles/indepth/features/pdf.md#input){:target="_blank"}.
