New Public Map Reveals Scope of America’s License Plate Reader Network

July 22, 2026

A grassroots organization called DeFlock has launched an online mapping platform that visualizes over 117,000 automated license plate reader (ALPR) cameras throughout the United States, revealing the extensive surveillance network that law enforcement agencies use to track vehicles. The project shows that more than 6,400 law enforcement agencies share ALPR data with one another, though only about 900 maintain public transparency portals, leaving most data-sharing arrangements hidden from public scrutiny. In Washington D.C., surveillance technology has grown steadily since 2006 when police began deploying closed-circuit cameras, with authorities defending ALPRs as vital tools for locating stolen vehicles and wanted individuals.

Who is affected

Drivers and vehicle owners across the United States whose license plates are captured by over 117,000 cameras
Immigrants targeted by ICE and CBP through Flock camera data
Communities and residents in Washington D.C. where surveillance has expanded since 2006
A Kansas man who wrote a critical op-ed about police
A Colorado woman wrongfully accused of theft based on an ALPR alert
A mother and her children held at gunpoint due to incorrect ALPR flagging
More than 6,424 law enforcement agencies using and sharing ALPR data
Grassroots activist organizations like DeFlock and civil liberties groups like the ACLU

What action is being taken

DeFlock is operating an interactive online mapping platform that visualizes ALPR camera locations and depicts data-sharing networks between law enforcement agencies
The ACLU is urging communities to oppose Flock technology and stand against mass surveillance
Communities across the country are fighting back against ALPR cameras
The Metropolitan Police Department is deploying and maintaining surveillance cameras throughout Washington D.C.
MPD is providing residents with an online application to search for fixed and mobile police cameras near specific addresses
Congress is examining potential legal implications of ALPR technology through Congressional Research Service reports
Courts are grappling with legal questions involving prolonged tracking, historical databases, and Fourth Amendment protections

Why it matters

This widespread surveillance network raises fundamental questions about privacy rights and the balance between public safety and civil liberties in modern America. The technology creates comprehensive historical records of vehicle movements that can be searched later, enabling tracking capabilities that courts and lawmakers are still determining may violate Fourth Amendment protections against unreasonable searches. The documented cases of misuse—including warrantless immigration enforcement, retaliation against critics, and wrongful accusations—demonstrate that ALPRs can be weaponized beyond their stated crime-fighting purposes. The lack of transparency, with only a small fraction of agencies maintaining public portals about their data-sharing practices, means citizens have little visibility into how their movement data is being collected, stored, shared, and used by law enforcement.
