Barrington Hills Police Department

Automatic License Plate Recognition (ALPR) Cameras

What is the aim of this program?  To check registration plates against state and local hotlists and alert officers to vehicles that may have been utilized in a crime, associated with AMBER or Silver alerts, or missing person investigations. Although it is preferable that the ALPR cameras be utilized to prevent or deter crime, the technology may also prove useful as an investigative tool and assist in identifying potential suspects.

Example of vehicle image captured with ALPR camera


What information will be captured? Cameras will capture a timestamped, still photo of a vehicle and record the registration plate using character recognition. The system may also identify the vehicle type, make, model and color. The photos do not include the driver or passengers in the vehicle. The cameras are not designed, nor intended, for automated enforcement of any traffic offenses.

How long will the Department retain captured photos and data? All photos and data are automatically purged after 30 days.

Where will the cameras be installed?  The initial cameras will be installed on the perimeter of the Village, where they will read and record vehicles entering. Additional locations may be considered in the future.

Can homeowner associations (HOAs) or private homeowners network into the camera system to monitor their private road? Absolutely! All vendors currently under consideration by the Department offer this capability. HOAs or private homeowners will have the ability to fund the annual camera cost to monitor their private road or driveway and automatically share captured data with the Police Department. Once a vendor is selected, details regarding this opportunity will be posted on the Village and Police Department websites, as well as social media.

Are other municipalities utilizing this technology?  ALPR cameras are currently utilized throughout the country, and locally in Chicago and numerous suburban municipalities with success. Vehicle thefts, burglaries, kidnappings, and hit & runs are some examples of incidents thwarted or solved using ALPR technology in other jurisdictions.
