UE 4.9 Materials & Textures problem

I want to add a camera feed to my game (like a security camera) and I have found a video there shows this:

The problem is that around 0:50 do he right-click on the Content Browser and gets a list of options under “Other assests”, but in the version I am using (4.9.2) do I only have an “Animation” option… how do I get the “Materials & Textures” option so I can make the camera feed?
