You'll need to either forward the ports through your router or use a service like logmein, teamviewer to access your home computer to access the cameras.
Do you want live cameras or the ability to rewind? If so, you'd need DVR software.
Teamviewer is wonderful, I need to tweak connection from outside and do some more testing.
I ended up using iSpy free version and it integrated my Airlink cameras with others.
so I will end up using 3 pda phones as cameras and 2 airlink wifi cameras. it records all those in time lapse.
