What Flock Cameras and ALPRs Do
Automated license plate readers — best known through the vendor Flock Safety — photograph every passing vehicle, log its plate, location, and timestamp, and store that record in a searchable database. Indiana agencies that disclose figures on their own transparency portals report roughly 690 vehicles detected per camera per day, so even a small deployment builds a detailed history of where residents of DeKalb County drive, worship, seek medical care, and gather.
Indiana currently has no statewide law limiting how long this location data is kept, who can query it, or how searches are audited. Whatever practices DeKalb County agencies follow today are voluntary and can change at any time.
