The Vienna Police Department operates its own network of Flock Safety license plate reader cameras on town streets, and an advocacy group that formed earlier this year wants them gone.
DeFlock Fairfax, founded by software engineer and privacy advocate Will Freeman, is pushing both Fairfax County and Vienna to end their use of the automated cameras, which photograph every passing vehicle and can alert officers in real time when a car on a law enforcement hotlist drives by. The group is holding a public meeting Saturday, Aug. 22, at Ravensworth Baptist Church in Annandale to build support, according to FFXnow.
Vienna PD says on its website that its Flock cameras allow retroactive searches to help solve crimes and provide real-time alerts for missing persons and Amber Alerts. The department has published a public transparency portal for its system. The exact number of cameras within town limits has not been publicly confirmed.
84 county cameras, plus Vienna's own
The Fairfax County Police Department operates 84 Flock cameras countywide, in addition to 712 Axon-brand readers mounted on patrol cruisers. The program has been running since November 2022.
Images captured by Flock cameras are stored on a cloud server for 30 days before being permanently deleted and cannot be sold or shared outside law enforcement, according to a 2023 FCPD announcement. The department also states it does not use the cameras to flag immigration violations and does not share data with federal authorities for immigration enforcement.
Flock Safety announced in August 2026 that it will reduce its default data retention from 30 days to seven days and require officers to enter a case number before running any search, effective Jan. 1, 2027. Whether FCPD will adopt the shorter window is unclear.
Results and opposition
Through July 1, FCPD's license plate reader program contributed to 1,503 criminal investigations, recovered 528 stolen vehicles valued at nearly $8.75 million, led to 870 arrests, recovered 64 firearms and located 56 missing people, according to the Fairfax County Times.
The department conducts a monthly audit of all LPR records and requires every search to be logged with the user's identity, date, time and justification.
DeFlock Fairfax first appeared before the Board of Supervisors at the April 16 public hearing, citing concerns over data sharing, oversight and civil liberties. At that hearing, Matthew Lofgren, speaking on behalf of Herndon Friends Meeting, told supervisors that tracking residents' movements without a warrant crosses a line, as the Fairfax County Times reported in July: "Normal red-blooded Americans don't like knowing their movements can be tracked at any time without a warrant."
The pushback extends statewide. A WHRO investigation published Aug. 14 found privacy advocates across Virginia have publicly opposed the cameras. Nationally, 95 municipalities have rejected or cancelled Flock contracts, and in July 2026 alone more than 20 jurisdictions either stopped using the cameras or began the process.
What Vienna residents should know
Residents can view Vienna PD's Flock Transparency Portal online or contact PFC Cherylyn Thompson, the department's public information officer, at 703-255-6335 for details on local camera placement.
No Board of Supervisors vote on the county's Flock contract is currently scheduled.
