What is Flock Safety?

Flock Safety is a private company that sells automated license plate reader (ALPR) cameras and surveillance software to law enforcement and homeowner associations. Their cameras log vehicle license plates, make, model, and color on every passing car, building a searchable database of vehicle movements.

How many Flock cameras are in the US?

Flock Safety cameras are deployed in over 5,000 communities across the United States as of 2026. The exact number of individual cameras is not publicly disclosed, but the network logs billions of vehicle movements per month.

Can you opt out of Flock Safety surveillance?

There is no universal opt-out from Flock Safety cameras. They are placed on public roads and private community property. You can request your data through some local jurisdictions or through DeFlock.org, but the cameras will still capture your plate on future trips.

Is Flock Safety legal?

Flock Safety operates in a legal gray area. ALPR technology is generally legal in most US states, but several cities and states have passed or are considering legislation to restrict its use, require data retention limits, or ban it entirely. Courts have not definitively ruled on whether mass ALPR surveillance violates the Fourth Amendment.

Flock: The Neighborhood Watch That Never Blinks

Flock Safety cameras log every license plate in over 5,000 communities, and police can subpoena Flock for vehicles of interest.

TL;DR

—Flock's system doesn't just catch car thieves.
—DeFlock remains operational and now tracks 16,000+ cameras worldwide.
—In states with abortion restrictions, Flock cameras become a dragnet that logs vehicles at clinics so police can subpoena Flock for vehicles of interest and reach the driver at their door, and prosecutors have already requested Flock data in reproductive healthcare cases.

Flock Safety sells "neighborhood security." What they deliver is a distributed surveillance network that logs vehicle movements across the United States.

The Hardware

80,000+ Cameras: Solar-powered, AI-enabled, reading every license plate that passes — across 5,000+ law enforcement agencies in 49 states.
20 Billion Scans Per Month: Flock's network processes vehicle sightings at an unprecedented scale.
Real-Time Alerts: Police get pinged when a "vehicle of interest" enters your neighborhood.
30+ Day Retention: Where you went, when, and how often — stored for a month by default, with indefinite retention in many jurisdictions.

The "Features" They Don't Advertise

Flock's system doesn't just catch car thieves. It builds behavioral profiles:

Pattern Detection: The AI learns your routine. It knows you go to church on Sunday and the bar on Friday.
Association Mapping: It knows who visits your house and how long they stay.
Geofencing: Some jurisdictions use Flock to create virtual "tripwires" around abortion clinics, protest sites, and political gatherings.
Data Sharing with ICE: The EFF documented Flock sharing data with federal immigration enforcement — a major driver of city contract cancellations.

The Pushback

Since the start of 2025, the backlash has accelerated:

30+ cities have canceled Flock contracts (Politico, The Guardian)
San José, CA faces a class-action lawsuit filed April 2026 alleging Fourth Amendment violations
Denver, CO paid $339,000 for 93 cameras, then rejected a $666,000 extension
Evanston, IL terminated its contract entirely in August 2025

When Flock sent a cease-and-desist to Will Freeman — the developer behind DeFlock, an open-source ALPR camera map — the EFF defended him. DeFlock remains operational and now tracks 16,000+ cameras worldwide.

The Post-Roe Nightmare

In states with abortion restrictions, Flock cameras become a dragnet:

Camera logs vehicle at clinic location.
Police subpoena Flock for "vehicle of interest."
Driver receives a knock on the door.

This isn't hypothetical. Prosecutors have already requested Flock data in reproductive healthcare cases.

The HOA Panopticon

The genius of Flock is that they don't need government approval. They sell directly to:

Homeowner Associations
Business Improvement Districts
Private neighborhoods

Your HOA voted 12-3 to monitor all vehicle movement. You weren't at the meeting. You're in the system anyway.
