This operating policy and procedure provides guidelines for the collection, retention and privacy of license plate recognition data at Central Michigan University.
Central Michigan University (CMU) uses license plate recognition (LPR) technology to manage parking on campus and enhance campus safety. CMU uses vehicle‐mounted systems, fixed camera installations and/or handheld devices to collect LPR data. CMU Police/Parking Services personnel shall be properly trained prior to using LPR equipment.
The LPR system captures up to two images of observed vehicles when a license plate is detected: a context image of the vehicle and its immediate surroundings, and an image of the license plate. Images taken are not of a resolution that allows for the identification of vehicle occupants, if any.
Along with the images, the LPR system also records the global positioning system coordinates and date/time information of the observation. Further software processing of the license plate image generates an alphanumeric version of the license plate number which is also stored with the record. The alphanumeric version of the license plate, date, time, and GPS information is referred to as metadata. The LPR system itself does not contain individual parking patron’s account information but may be linked to such information by CMU Parking Services.
Use of data
CMU Parking Services uses LPR data primarily for the purpose of parking enforcement, analyzing campus parking utilization and managing the parking programs at CMU. CMU Police Department may use LPR data in the response to immediate or ongoing safety concerns, conducting criminal investigations, and other compulsory law enforcement activities. As such, personally identifiable LPR data is accessible only by limited parties, including CMU Parking Services/CMU Police staff, their agents and vendors, and the OIT personnel that maintain the data, websites, and LPR infrastructure.
Access to records
CMU will notify the public of its LPR data collection activities and policies by posting and updating this policy on the CMU Police/Parking Services website.
