How many cameras are able to connect to the Homebase3?

I've got a set up started on our 1 acre property & was wondering how many cams the Homebase3 can connect to.

I've got 10 on it so far & I know I will have to get a second one when I do the stretch outback & in the woods but I was hoping that I could get away w/ one homebase for the area around the house.

2 are continous recording ones, hoping to add a few more continuous but not sure on the limit w/ that either.

Anyway, thanks for your time!
