The miku's multiple camera options are great for those who want to monitor their kids without having any one point of access. You can add as many cameras as you need, but make sure that they are all open on different devices because the kit doesn't notify users about alerts in real-time - you'll only know when it happens through notifications from either banner ads popping up over top apps' iconography (which may vary based upon user preference) if available via Apple Watch sound detection capabilities.
