My home setup is with DECO  3 M9 Plus and 2 M5 units.

my outdoor nest cam outside over the garage loses signal constantly. Want to add an outdoor access point in order to provide bettter wi fi signal to the outdoor nest cam. Which outdoor access point would allow a seemsles connecrion to my setup? Meaning that I would still be able to see the camera on my nest app on the same network as I do today? 
 

thanks
