Ring motion detector help

Hi
I have seen this ring motion detector.
It says it notifies your phone of any motion?

I was wondering how does this work? As i want to place in my garage. Does it need to have wifi connection to work with my phone? If not then thats great as there is no signal there
Let me know someone please before i purchase?
Thank you
