real-time camera in viewport

I was wondering if there is a way to import and display my real camera, let’s say Canon DSLR, into the UE4 viewport so I could use it to align and composite my live footage with 3D?

Thank you

I think this link may be of use to you:

Not exactly what I had in mind but kind of in the right direction. Basically, I want to have the UE4 main viewport as the monitor for my camera and I can input assets on top of that image like a compositor, kind of making the camera footage as my background.

But thanks for the link it can prove to be useful.
