An ALPR system's high speed cameras can do a lot of things very quickly. They can read hundreds of license plates per minute, capture contextual photos of vehicles, translate the image of a plate into alphanumeric characters, and ultimately aid in solving crimes and locating missing persons. Most systems can read plates day or night, in all types of weather conditions, and many manufacturers advertise they read plates from all 50 states in the U.S. and most foreign countries.

 A deputy in Boone County Missouri was involved in a serious accident in December which caused his patrol car to roll several times. Thankfully, the deputy and the other driver were unhurt, according to David Alexander, operations analyst for the Boone County Sheriff's Office. 

Alexander was also surprised to find that the three ALPR cameras affixed to the roof of the patrol car were still fully functional after the wreck and will be reinstalled onto another vehicle this spring. 

A mobile license plate reading system that the Salisbury Township (Pa.) Police Department implemented last year has generated “incredible law enforcement dividends and helped make driving safer for those who travel Salisbury Township roads and highways.”
