A:Answer The sync module 2 will still function like a traditional sync module, compatible with all generations of Blink cameras (indoor, XT, XT2, Blink Indoor and Outdoor, and Blink Mini), However, Only Blink Indoor and Outdoor and Blink Mini cameras will be compatible with local storage functionality. All other generations of cameras (indoor, XT and XT2) will be cloud based if/when they are added to the sync module 2.
