The moments before the break-in were caught on camera. Kris owns a "Ring doorbell", which sends a live feed direct to his cell phone.
 
The doorbell has a tiny camera inside, so you get a really good look at the would-be burglars.
 
“They’re coming in. There’s no question. They’re coming in,” said Kris.
 
The video shows the unwelcome guests ring the doorbell to see if anyone is home.
 
“The voice, what he says in there, their demeanor, they’re not here to sell cookies,” explained Kris.
 
Kris was inside his home, watching the crooks from his cell phone. Video from the Ring doorbell shows the intruders talking to each other. They appear to be confused by the doorbell.
 
In the video, one can be heard saying, “You need an eye scanner? Is that how I get into the house? An eye scanner?”
 
Seconds later, the crooks are in Kris’ backyard. Except now, there are four people. Kris pulled out his gun.
 
“They had flashlights and I’m basically just seeing silhouettes of their bodies moving around the backyard,” said Kris. “And as soon as one comes two feet into my home, I fire two rounds.”
 
Kris said he ran outside and fired two more rounds. The intruders took off and Kris called 911.
