He set up a cloud-based camera service called Dropcam in his living room. The camera is triggered by sound or motion and sends the user an alert.
That's how he got some of the clearest surveillance video we've ever seen of men stealing valuables from his home.
Yancey showed the video to Durham police.
"They sent one officer last night and as soon as he saw the footage he couldn't put a name to the footage but he thought he recognized the first guy in the tape, one of their frequent fliers," said Yancey.
Detectives quickly identified one of the suspects as 22-year-old Quadele McCoy. Police say the man in the red hoodie is 23-year-old De'rese Anderson.
Warrants have been issued for McCoy and Anderson but they are not in custody at this time.
If you know where they are - or can help identify the other suspect in the video, please give Durham police a call at: (919) 560-4440, or CrimeStoppers at (919) 683-1200.
