No state or federal laws currently regulate Automated License Plate Readers (ALPRs) in Kansas, leaving local police departments in Johnson County to establish their own policies. This means rules on data storage, access, and sharing vary significantly across cities, as The Johnson County Post reported on October 1, 2026.
ALPR cameras capture license plate information, compare it against "hot lists" of vehicles of interest, and can store this data for investigative purposes. Some departments have formal internal policies, while others have no specific rules for these devices.
What are Johnson County departments doing with ALPR data?
Departments across Johnson County use various ALPR systems from different manufacturers. Here's a breakdown of current practices:
- Overland Park: Operates 38 fixed Genetec cameras and 113 mobile Axon cameras. Data is stored for one year, owned by the department, and shared with some local agencies but not federal ones. Access is restricted, logged, and audited.
- Olathe: Uses ELSAG and Genetec mobile and fixed units. Data is stored for 90 days in an Olathe database and can be shared with other departments with permission. Access is logged and auditable.
- Shawnee: Uses a mix of mobile and fixed units, with data stored for 180 days. Data is for "official business" only, with access protocols set by a commander. Other agencies can request access.
- Lenexa: Uses Leonardo, Axon, and Genetec cameras (40 fixed, 42 mobile). Data is stored for 60 days. Access is limited and monitored, with a new ALPR policy under review.
- Leawood: Has 13 fixed Genetec units. Data is stored for one year and owned by the department. Access is restricted to authorized personnel, and policy revisions are underway.
- Gardner: Recently discontinued two fixed and two mobile Flock cameras due to public concerns but continues to use 15 mobile Axon cameras. Data from Axon cameras is stored for 30 days, access is limited, logged, and audited, and data is not shared with other agencies.
- Prairie Village: Operates 30 fixed Axis cameras and 25 fixed cameras in Mission Hills, using Genetec software. Data is stored for 90 days on department servers. Access requires a log-in, specific reason, and is audited semi-annually.
- Merriam: Uses 19 fixed Genetec cameras. Data is stored for up to 180 days. Access is for trained officers and analysts, logged, and audited quarterly.
- Spring Hill: Uses 10 mobile Axon units and one mobile Leonardo unit. Data is stored for 90 days. Access is restricted, logged, and audited annually.

- Fairway: Uses seven fixed and one mobile Genetec camera. Data is stored for 90 days. Access is logged, auditable, and shared with some agencies via memorandum of understanding.
- Johnson County Sheriff's Office: Uses about 50 LPRs, including two fixed and one mobile Flock camera, along with Genetec and LSAG units. Data is stored for 90 days. Access is limited to authorized users, logged with a specific reason, and audited annually. Fixed units are in De Soto, Gardner, Mission, Olathe, and Fairway.
Several cities, including De Soto, Edgerton, and Westwood, do not operate their own ALPR cameras.
What does this mean for drivers?
Drivers in Johnson County face a patchwork of policies regarding ALPRs. Your license plate data could be captured and stored for varying periods, from 30 days to one year, depending on the city you are in. While most departments claim data access is restricted and audited, the lack of consistent state regulation means protections can differ significantly. For example, some departments share data with other agencies while others do not. You can explore where cameras are located on our /map.
If you have concerns about ALPR usage or data retention, you can inquire with your local police department about their specific policies. Some departments, like Lenexa and Leawood, are reviewing or revising their policies, indicating an ongoing conversation about these technologies. The Electronic Frontier Foundation recommends policies that include warrant requirements for hot lists, short data deletion windows (like New Hampshire's three-minute rule for non-hits), and regular internal and external audits to ensure proper use.
