That's correct, there is a maximum of 10 per home. To workaround this you can create another home in the app and add further cameras to that new home.
@Jbird1, just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, we would be happy to keep it open. If there's more we can do, just let us know.
I appreciate the help, davidking and Brad.
