Smartview setup. What's the order?

Setting up a control room for a high school tv studio. We have two Micro Studio Camera 4K in the studio running into a ATEM Television Studio Pro 4K.

My question is, where in the order of connections do we put our two Smartview Duos?

Is it: Camera to Switcher to Smartview? Or, is it: Camera to Smartview to switcher?
What about the return SDI back to the camera for control?

Thank you,

Reid

I run all my cameras into the monitors then on to the switcher. I want to see what the cameras are seeing without any changes from the switcher.
