Electrical engineers equipped his patrol car with four 360-degree cameras that scan license plates in just seconds.
"Just in the matter of the little bit of time we've been sitting here, we've already scanned you know 15, 20 cars very easily," said Captain Santiago.

"This car is probably doing what it would take 50 deputies two or three days to do and it can do it (snap) that quick," said Sheriff Lott.
Keeping the streets safer in a fraction of the time.
