Multi Cameras?

[Dixie Life]

Now I have a e7d RM on the FB for chart plotting, etc.. It has only one camera input. My question is, if I want to connect say three cameras what equipment do I need. Or, can this even be done without upgrading to the larger RM display?

My understanding is that more than one input is generally connected through a Raymarine network switch. That's described a bit on page 58 of the manual.

B&B that would be if they're IP cams which I doubt he has.

I think one of these is what he needs.
