The fire started on his front porch in the middle of the night and his doorbell's motion detector picked it up, sending him alerts to his phone.
Surveillance video from the doorbell shows homeowner Mike Hernandez trying to put the fire out with an extinguisher.
Eventually he woke up his fiance and brother and all three escaped unharmed.
"Took down our smoke detector because we just repainted the entire house. Without the Ring system in place and me getting these alerts I probably would not have woken up," said Hernandez.
Corona firefighters saved the home which had just been purchased a month ago, but it sustained major damage.
