Illinois State Police are using surveillance cameras again this year at the State Fair, particularly in high-traffic areas such as the carnival to more easily monitor large crowds, according to a Chicago Tribune report.

 

The security cameras stream live to the state police's fairground headquarters to help troopers watch large crowds, the report said. There will be signs to indicate certain areas are being filmed.

 

As of Sunday, there had been no arrests at the fairgrounds, although state troopers had kicked out about 12 people during the course of the fair for such minor indiscretions as disorderly conduct and public intoxication, the report said.
