The deployment and expansion of Automated License Plate Reader (ALPR) technology across North America has triggered a debate regarding public safety and privacy rights.

In the United States, law enforcement proponents argue that ALPRs are essential for identifying suspects, recovering stolen vehicles, and locating missing persons. However, privacy advocates contend that the technology enables unprecedented mass surveillance by creating detailed records of movement. Critics argue that querying these databases can reveal intimate patterns of life and suggest that such searches should require warrants.

As the technology expands, specific concerns have emerged regarding the scale of deployment. Flock Safety has reportedly deployed over 120,000 AI-powered cameras, though a lack of public master maps makes it difficult to track all active units. Following reports of system misuse—including an investigation by The Washington Post revealing instances where officers used the technology for personal reasons such as stalking—Flock Safety is implementing new privacy and security controls. These measures include reducing the default data retention period from 30 days to seven days, requiring mandatory case codes for all searches, and introducing automated systems to flag unusual activity.

Despite these updates, privacy advocacy groups like the ACLU and the EFF have criticized the measures as insufficient. The ACLU has called for a much shorter 48-hour retention period and expressed concerns that the new ‘Evidence Mode’ could still allow for the collection of data on innocent individuals. This controversy has led to approximately 50 cities reportedly severing ties with the company. Resistance continues in Florida, Nebraska, and Canada, where legal experts warn of a potential “surveillance state.” Additionally, the technology has faced challenges from activists through vandalism and from cybersecurity researchers demonstrating methods to evade camera detection software.
