Automated License Plate Readers (ALPRs)
Many police departments around the country, including the Dallas force, use ALPRs to conduct mass surveillance.
Dallas PD: As of 2015, the department operated 26 mobile ALPRs and 15 fixed ones. In the linked report, Dallas Police tested a Vigilant Solutions' ALPR trailer, which can be moved around the city and stationed at various areas. Currently, we've submitted a Freedom of Information Act (FOIA) request to obtain updated statistics.
Coppell PD: Also uses Vigilant Solutions. This PDF here shows all of the various departments that they share their information with, whule this PDF states that they scanned 36,277,806 license plates in 2019.
Grapevine PD: This data comes from 2012 and shows that they purchased ten cameras. A news report from 2014 states that the department had 4.7 million plates in their database (they never purge their data).
Fort Worth PD: Fort Worth operates 63 Flock Safety ALPR cameras, which were installed in early 2021. Furthermore, the police department operates a Real Time Crime Center with a camera network throughout the city. Last year, they refused to detail camera locations. Video report here.
Arlington PD: Uses Motoral Vigilant license plate recognition on 11 police cars.
Dallas County Sheriff's Office: operates four ALPRs and doesn't store the data, as of 2013.

Flock Safety also markets to Home Owners Associations. Beyond police surveillance networks, this allows private surveillance networks to also exist around North Texas. In 2019, the Stonecourt neighborhood in Bedford, TX added ALPRs to their front gate. Private networks are also much harder to keep track of than government ones, because they are not required to disclose this information to the public.
