This system is very nice as if you use the home plug system such as
Modem (internet provider) > router > home plug sender> home plug reciever (another part of the house)> videophone (OJO, VP200 or VP100).
or
Modem (internet provider) > router > home plug sender> home plug reciever (another part of the house)>
switchboard> videophone (OJO, VP200 or VP100).
This way you can skip the wireless if you dont like the idea of wireless or have connection issues as concret walls in the older houses.
I have a friend who did not want to spend 300 to get electric man to install ethernet to bedroom, I recommended and he installed home plug. It worked perfectly with vp and computer in new bedroom. Only cost him under 100 dollars.
