In the spawn menu under the bar labeled 'tools' there is a subsection labeled 'camera' on the sidebar that opens when you click on it there is a button that says something along the lines of "choose a key to bind" click on the button, press the key you want to use to a to activate the camera, and you're good to go.

I have my camera bound to '9' which is probably the best key for it.

I think they mean the camera in the dupe

the thing is whatever you have binded goes with the dupe, so you should tell people what key to press.

to use the camera in this dupe you must press the 9 key (not at numpad)
