Backup Camera on Android?
I'm revisiting the idea of building a car PC but to save on costs I think I'm just going to use an Android tablet/large phone instead of a small PC and touchscreen (a tablet will be about half the cost and take up less space in my tiny car). I've got pretty much everything worked out except for connecting a back up camera to the Android. I know there are apps that support webcams but most backup cameras use RCA connections. How can I connect one of those to an Android device?
