EX2700 - Can I use an Ethernet Junction Box to run 3 Cameras?

OK, Here Goes.....

I have a Netgear EX2700 WiFi Extenser in my garage....about 50 Ft from my Router.

It picks up a very strong signal.

So, Can I attach the ethernet cable from the extender to an ethernet "Junction Box" (The INPUT),

AND then run 3 separate ethernet cables (The Output) from the Box to 3 separate cameras located in my garage?

SO,.......Will ONE EX2700 extender support Three Cameras?

These are 'On Demand' cameras, on only when I sign in and want to see the view, no recording, etc.

Right now I have three exrenders, two inside the garage where the signal is much less than the one closest to the router.

Would be great to just use one.

Please advise.

Thanks for your time.
