Privacy Rights & Laws: What You Should Know About ALPR and Flock Cameras

By FlockOut Rapid City

Automated License Plate Recognition (ALPR) systems, including those offered by companies such as Flock Safety, are becoming more common in communities across the United States. These systems are designed to assist law enforcement by capturing images of passing vehicles and reading license plates.

As the use of ALPR technology expands, many citizens ask an important question:

"What are my privacy rights?"

The answer depends on several factors, including federal constitutional protections, state laws, local policies, and how the technology is used.

The Fourth Amendment

The Fourth Amendment to the U.S. Constitution protects people against unreasonable searches and seizures by the government.

Courts have generally held that drivers have a reduced expectation of privacy regarding information that is plainly visible in public, including:

  • License plates

  • Vehicle color

  • Vehicle make and model

  • The location of a vehicle traveling on public roads

Because license plates are displayed publicly by law, a single ALPR scan of a plate has often been treated differently from a search of private property.

However, legal questions become more complex when large numbers of scans are collected and retained over time, allowing travel patterns or long-term movements to be analyzed.

Public Roads vs. Private Property

In most situations:

On Public Roads

Vehicles traveling on public streets may be photographed by ALPR systems because license plates are visible to anyone lawfully present.

On Private Property

Different legal and policy considerations may apply depending on:

  • Property ownership

  • Consent

  • Local laws

  • Camera placement

  • Contracts between property owners and technology providers

What Information Is Collected?

An ALPR system may record:

  • License plate number

  • Date and time

  • Camera location

  • GPS coordinates (depending on the system)

  • Direction of travel

  • Vehicle photograph

  • In some systems, the vehicle's make, model, color, or distinguishing characteristics

Many systems are designed to recognize the vehicle, not the identity of the driver.

Who Can Access the Data?

Access policies vary depending on the organization operating the system.

Potential authorized users may include:

  • Local law enforcement

  • Sheriff's offices

  • State agencies

  • Other agencies through approved information-sharing agreements

Access is typically governed by agency policy, user permissions, and auditing requirements.

Data Retention

One of the most frequently discussed privacy issues is how long ALPR data is retained.

Retention periods are usually determined by:

  • State law

  • Local ordinances

  • Agency policy

  • Contract terms

Some jurisdictions require shorter retention periods, while others allow longer retention for investigative purposes.

Public Records

Many records related to ALPR programs may be subject to state public records or open records laws.

Depending on the jurisdiction, members of the public may be able to request records such as:

  • Agency policies

  • Procurement contracts

  • Privacy impact assessments

  • Annual reports

  • Budget information

  • Audit summaries

Some investigative records may be exempt from disclosure under applicable law.

State Laws Matter

There is no single nationwide ALPR law.

Instead, regulation is often established through:

  • State legislatures

  • Local governments

  • Agency policies

  • Court decisions

Some states have enacted laws addressing:

  • Data retention limits

  • Permitted uses

  • Access controls

  • Information sharing

  • Required audits

  • Security standards

  • Public reporting requirements

Others rely primarily on agency policy.

Privacy Questions Citizens May Ask

Communities often discuss questions such as:

  • Why was this technology adopted?

  • What public safety goals does it support?

  • Who has access to the information?

  • How long is data retained?

  • What safeguards prevent misuse?

  • Are independent audits conducted?

  • What cybersecurity protections are in place?

  • How are errors corrected?

  • What oversight exists?

These questions can help inform public discussions about the appropriate use of surveillance technology.

Responsible Use

Many public agencies emphasize several principles when deploying ALPR technology:

  • Transparency

  • Accountability

  • Clearly defined policies

  • User training

  • Audit logs

  • Cybersecurity protections

  • Compliance with applicable laws

These measures are intended to support lawful and responsible use of the technology.

What Can Citizens Do?

If you want to learn more about how ALPR systems are used in your community, consider:

  • Reading your local agency's published policies.

  • Attending city council or county commission meetings where technology purchases are discussed.

  • Reviewing publicly available contracts and budgets.

  • Asking questions about data retention, access controls, and cybersecurity practices.

  • Learning about your state's public records laws and privacy protections.

An informed community is better equipped to participate in thoughtful discussions about public safety, privacy, and emerging technology.
