Flock Cameras: Automatic License Plate Readers, Public Safety, and Privacy Concerns

Flock Safety cameras, often referred to as automated license plate readers (ALPRs), don’t just record traffic; they continuously capture license plates and feed them into searchable databases. As these systems continue to expand across neighborhoods and city corridors, questions are growing about how widely they track everyday movement, who can query the data, and how easily “public safety” purposes can expand over time. Here’s what Flock cameras do, where they’re being installed, and why many people argue that this kind of persistent, location-linked surveillance crosses privacy lines.

What are “Flock cameras”?

“Flock cameras” refer to Flock Safety’s automatic license plate reader (ALPR/LPR) systems, which are camera devices that continuously capture passing vehicles’ license plates and store that information in a searchable database. In Berkeley, for example, the readers are described as monitoring every vehicle that passes, enabling alerts and allowing police to search a database of plate reads.

Where are they’re being installed?

These systems are being installed nationwide by local police agencies and, in some cases, by private organizations, such as businesses or community groups, that contract with Flock. Recently, it has been reported that Berkeley police have been using Flock’s plate readers for nearly two years, and that the city has approximately 52 Flock plate-reading cameras installed around the city (with other, separately monitored systems nearby and used by police in housing areas under a pilot). More broadly, reporting and advocacy coverage describe Flock as selling cloud-connected ALPR camera networks to “thousands” of communities/agencies nationwide, forming a large-scale “public-private safety network.”

Why are these cameras considered an invasion of privacy?

The core privacy issue is that ALPR systems don’t just capture information about a specific incident – they create a broad record of where vehicles go over time, for everyone who drives by, including people not suspected of any wrongdoing. Since license plates are linked to vehicles and vehicles are linked to people’s daily movement, the effect is persistent tracking of location-linked behavior.

They also raise concerns about scale and “function creep” (expansion beyond original justification). Flock’s evolution from plate reading toward broader video/surveillance capabilities and more powerful search, including uses that capture more than just plates and allow law enforcement to query richer datasets.

Finally, there is significant potential for misuse/oversight issues. When large databases are accessible to many users and can be searched broadly, the risk is that tools designed for public safety can be applied in ways that sweep in innocent people and enable improper or abusive surveillance – especially when searches are not tightly constrained.

Flock Safety’s cameras are marketed as a public-safety tool. Still, the same technology that can help locate vehicles after an incident can also create a broad, searchable record of where people drive day-to-day. That’s why privacy advocates push for clear limits on use, strong oversight, and transparency about placement and data access. Whether you support or oppose these systems, understanding how they work, and what they enable, makes it easier to judge the tradeoffs before they become permanent fixtures of everyday life.
