The Fairfax County Police Department marks the two-year anniversary of the implementation of license plate reader technology which launched in November 2022.

License plate reader technology has been commonplace in policing for many years. Both fixed and mobile license plate readers have been used in a number of cases over the past two years.

License plate readers have helped investigative efforts in hundreds of complex cases over the past two years, including malicious woundings, attempted rapes, burglaries, and other offenses. Most recently, license plate readers have helped in the fight against organized retail theft.

License plate readers have resulted in many stolen vehicles being located. Officers and detectives have also used license plate readers to recover 43 firearms and locate 30 critical missing people in Fairfax County.

License plate readers have helped officers addressing traffic-related issues and engaging with residents.

“The FCPD remains committed to leading the way in data-informed policing practices, utilizing technology responsibly to align with the needs and expectations of our community,” said Chief Kevin Davis. 

FCPD has made multiple changes to its license plate reader program since its inception, including a 92% reduction in data retention length by keeping the stored data for only 30 days across all license plate reader systems. Additionally, FCPD does not get any license plate reader alerts regarding immigration enforcement warrants, driver’s licenses, registration, or inspection violations. A reinforced policy, expanded training, and accountable oversight measures are all part of the additions to the program.
