Automated License Plate Readers (ALPR) in Fairfield


The Fairfield Police Department utilizes Automated License Plate Reader (ALPR) cameras at locations throughout town to help locate stolen vehicles, support missing-person alerts, and provide objective evidence after crimes. Access to ALPR data is strictly limited to legitimate law-enforcement purposes. Consistent with the Connecticut TRUST Act, we do not use or share ALPR data for civil immigration enforcement.

How ALPR Works

Axon Cam 600

ALPR cameras capture license plates and certain vehicle characteristics visible from public roadways. The information is converted into searchable data for authorized law enforcement purposes.

They can assist police in identifying stolen vehicles, wanted persons, missing or endangered persons, and vehicles associated with criminal investigations.

An ALPR alert is an investigative tool and does not confirm criminal activity. Officers are required to verify information and take additional investigative steps when appropriate.

What's Detected

  • License plate numbers
  • Date, time, and location of the read
  • Vehicle make, model, color, and other characteristics when available
  • Direction of travel when avaialbe
  • Alerts associated with authorized law enforcement searches and Hot Lists

What's Not Detected

  • People inside the vehicle
  • Driver or passenger identities
  • Facial recognition
  • Activity occurring inside the vehicle
  • Personal information unless separately associated with a license plate through authorized law enforcement databases

Privacy, Access & Safeguards

The Fairfield Police Department has established policies and safeguards governing the use of ALPR technology, access to ALPR information, data retention, and information sharing.

Acceptable Use Policy

ALPR data may only be accessed and used for legitimate law enforcement purposes. Authorized uses include criminal investigations; locating stolen vehicles or license plates, wanted persons, and missing or endangered persons; investigating serious or fatal crashes and evading-responsibility cases; and other authorized public-safety purposes.

Prohibited Uses

ALPR systems and data may not be used for personal purposes, harassment or intimidation, to target individuals based solely on a protected characteristic, or to knowingly infringe upon constitutionally protected First Amendment rights. Policy also restricts the use of ALPR data for civil immigration matters and investigations involving reproductive, gender-affirming, or other health care services that are legal in Connecticut.

Access Policy

Access is restricted to authorized, properly trained personnel using individual login credentials. Each query must be for a permitted purpose and requires the user to document the search parameters, reason for the query, and associated case or identifying number. System activity is logged and subject to regular audits to ensure compliance with Department policy.

Data Retention

ALPR data is retained for no more than 30 days unless it is preserved as potential evidence in a criminal, administrative, or civil matter.

Data Sharing

ALPR data may only be shared for official law enforcement or public safety purposes.

Before ALPR data may be shared with an out-of-state law enforcement agency, the requesting agency must submit a request and affirm in writing that it will comply with Fairfield Police Department policy and Connecticut law, including the Connecticut Trust Act and state protections related to reproductive health care and gender-affirming health care. If the required written affirmation is not provided, the data will not be shared.

Hot List Policy

Hot Lists are limited to legitimate law enforcement purposes. Manually adding a vehicle or license plate requires a documented law enforcement basis and supervisory approval. Entries must include identifying case information, have an expiration date, and be removed when the investigative need ends or the vehicle is located. Hot List alert hits are verified as accurate by Fairfield police officers prior to any enforcement action being taken.

Success in Action
ALPR technology has assisted Fairfield Police in a variety of criminal investigations and public safety incidents. The following are examples of cases in which ALPR technology contributed to an investigation:
JUNE 2026
 
Arson Investigation
After determining that an individual likely intentionally set fire to an occupied Fairfield residence and fled the area, officers used ALPR data to track and locate the suspect vehicle just 23 minutes later. Quickly locating the individual was especially important because officers did not yet know her intentions or whether she posed a danger to herself or others. The investigation resulted in an arrest.
MAY 2026
 
Reckless Driving Investigation
After an officer observed a vehicle traveling at a high rate of speed but was unable to catch up to it, mobile LPRs on other patrol vehicles captured the vehicle’s license plate as it traveled through the area. The information allowed officers to identify the vehicle and locate the driver, who admitted traveling approximately 60 mph in a posted 30 mph zone and was issued a citation.
MAY 2026
 
Stolen Vehicle
While on patrol, a mobile LPR alerted officers to a passing vehicle associated with a theft report. Officers followed the vehicle while confirming its stolen status and ultimately located it in Bridgeport. The investigation resulted in the renter’s arrest for Larceny of a Motor Vehicle.
FEBRUARY 2026
 
Following an armed home invasion on Candlewood Road, ALPR technology assisted detectives in developing evidence against individuals involved in the incident. The investigation ultimately resulted in the identification and arrest of those believed to be responsible.
DECEMBER 2025
 
Commercial Burglary Spree
During a series of overnight commercial burglaries along Post Road, ALPR cameras captured a vehicle entering and leaving the area around the time of the crimes. Working with regional partners, investigators identified the suspect and obtained an arrest warrant.
JULY 2025
 
Missing Person
In another example, ALPR systems were leveraged during the search for a missing Fairfield woman with dementia. Alerts were added across regional plate readers, helping investigators quickly rule out certain areas and focus resources. Combined with financial tracking and interagency coordination, the subject was safely located in New Haven within hours.
JUNE 2025
 
Fatal Crash
Following a tragic crash where the driver fled the scene, officers used ALPR evidence to quickly identify and locate the suspect’s vehicle, leading to an arrest the same evening.
JUNE 2025
 
Financial Exploitation Case
In an investigation involving the financial exploitation of an elderly resident, ALPR data assisted detectives in identifying a suspect vehicle connected to the incident. The information supported the issuance of an arrest warrant.
MAY 2025
 
Street Takeover
ALPR cameras also played a key role in a major investigation after a reckless “street takeover” endangered dozens of people at a local shopping plaza. By combining ALPR data with community videos and interagency support, officers identified multiple offenders across different towns, leading to several arrests and vehicle seizures.
FEBRUARY 2025
 
Bias Crime Investigation
During an investigation into bias motivated graffiti, ALPR technology helped identify a vehicle associated with the incidents. Detectives identified and charged the responsible party.
DECEMBER 2024
 
Armed Carjacking
After a delivery driver was robbed at gunpoint, ALPR cameras helped investigators identify a vehicle involved in the crime. The case resulted in charges and recovery of evidence.
NOVEMBER 2023
 
Commercial Burglary
After a burglary at a local jewelry store, officers used ALPR data to identify a suspect vehicle that had entered Fairfield prior to the crime. Working with neighboring agencies, detectives located the vehicle and arrested the suspect.
AUGUST 2022
 
Fatal Hit and Run
Following a fatal motorcycle crash where the driver fled the scene, ALPR cameras helped identify a vehicle matching the description provided to police. Investigators located the operator and made an arrest.
These cases demonstrate how ALPR is being used responsibly to solve crimes, locate vulnerable community members, and protect Fairfield while remaining fully compliant with state law and civil liberties protections.
Frequently Asked Questions
How did surveillance cameras get installed in our Town without extensive public hearings, and even a referendum?
  • The genesis of this program, which initially used Flock cameras, occurred under a previous Town administration and previous police administration. Therefore, we cannot speak from firsthand knowledge regarding the conversations or processes that led to its implementation. That said, generally speaking, absent a federal or state law requiring a public-hearing or referendum process for a particular technology or program, the acquisition of police technology does not necessarily require a separate public hearing or referendum.
  • Fast forward to the current administration and the transition to AXON: The full AXON contract rewrite, which incorporated the replacement of the Flock system, was presented during the Town's public budget process, where public comment was permitted. The contract details were submitted to the appropriate Town boards and were discussed during public budget hearings. Meeting agendas are published on the Town's website in advance, allowing members of the public to review the matters being considered, formulate questions or concerns, and attend meetings either in person or virtually.

  • It is also important to understand that, while the AXON contract incorporated an ALPR component, the broader contract was largely focused on increasing police accountability and transparency. With access to cameras on the network, use of drones, Taser deployments, and other technology comes a detailed audit trail. Time stamps, user identification, query information, and other system logs provide the ability to determine who accessed information, when it was accessed, and why it was accessed.
How much did these cameras cost, and where in the budget did the money come from? What else might have been done with that money? Perhaps hiring more officers, improving community relations, or increasing resources for conventional investigations that do not run the risk of turning our Town into a surveillance state?
  • Full details of the AXON contract can be found here: CONTRACT

  • As part of the normal FY27 budget process, requiring three board approval in public budget hearing sessions, the town increased the Police Department’s “Information Technology” budget line to cover the costs of the AXON contract. This is all publicly accessible information on the town website.

  • These are legitimate questions whenever public funds are being spent, and reasonable people can disagree about how limited resources should be allocated.

  • While increasing the size of the police force is always desirable when staffing levels and finances permit, there is also a responsibility to remain current with the investigative techniques, equipment, and technology available to modern law enforcement. Criminal activity has changed considerably, and many investigations now depend upon digital or video evidence that simply did not exist—or was not readily available—years ago.

  • ALPR technology is not a replacement for police officers, traditional investigative work, or community policing. It is another investigative tool. Used properly, it can help officers identify stolen vehicles, locate missing or endangered people, identify vehicles associated with criminal investigations, and develop evidence after a crime has occurred. The goal is not to monitor law-abiding residents; it is to provide investigators with another tool to solve crimes, protect victims, and hold offenders accountable.

  • At the same time, the public is absolutely entitled to ask how that technology is governed. That is why clear policies, limited access, documentation, auditing, appropriate retention periods, and meaningful accountability are essential. The technology should serve the public—not operate without rules or oversight.
What ALPR technology does Fairfield use? Does the Department use Flock Safety or participate in the Flock ALPR network?
Fairfield Police currently uses Axon ALPR technology. The Department does not use Flock Safety cameras and does not participate in Flock’s ALPR network.
Does Fairfield own and maintain administrative control over the ALPR data collected by its cameras?
Yes. Fairfield owns and maintains administrative control over the ALPR data collected within its system.
Where is Fairfield’s ALPR data stored, and how is that information protected?
Fairfield’s ALPR data is stored within Axon’s Evidence.com environment and is protected using end-to-end AES-256 encryption. The Department also controls system access through role-based permissions, limiting access based on an individual’s authorization and responsibilities.
What exactly is a “legitimate law enforcement purpose?” Can I and my family be tracked because of a broken tail light? Similarity to a person of interest? Proximity to a crime? Falling within a geofence?
  • There are a number of permitted uses under Connecticut's current ALPR framework, depending upon the circumstances of the investigation. The current POSTC ALPR Model Policy identifies permitted uses including:
    • identifying stolen or wanted vehicles;
    • identifying stolen license plates;
    • locating missing, exploited, or endangered persons;
    • locating persons with outstanding warrants or persons suspected of crimes;
    • cases involving flight or evasion from law enforcement;
    • locating fugitives from justice;
    • certain situations in which physical surveillance of a criminal-investigation target would be dangerous or compromised;
    • certain emergencies, such as wrong-way drivers, apparently intoxicated operators, or persons experiencing a medical emergency;
    • fatal or serious-injury motor vehicle accidents;
    • crashes involving evading responsibility;
    • circumstances meeting an exigent-circumstances exception to the Fourth Amendment; and
    • certain national-security and counterterrorism purposes.

  • Importantly, the policy does not authorize ALPR queries simply because someone is interesting, because their vehicle happens to be in a particular location, or because an officer is curious about where someone has been. For criminal investigations, the POSTC policy requires reasonable suspicion that a criminal offense was committed. The user must also document the reason for the query and provide a case number or other identifying number.

  • A broken taillight does not, by itself, make someone's vehicle a wanted vehicle or authorize an officer to conduct a historical ALPR search simply to see where that person has been. Similarly, a person's presence near a crime does not automatically make that person a suspect or independently establish a legitimate purpose for searching ALPR history.

  • As for geofencing, the technology should not be viewed as creating an independent authorization to conduct a search. Any query still has to satisfy an otherwise permissible law-enforcement purpose and the applicable legal and policy requirements.
Who within the Fairfield Police Department is permitted to access ALPR data, and who authorizes that access?
Access to ALPR data is limited to authorized supervisors and investigators. Access is approved through the Field Services Bureau Commander. Each search requires the user to enter a police file number and the investigative purpose for the search. Search activity is logged and subject to audit by the Office of Professional Standards.
What guarantees do we have that those with access to the cameras will not disregard regulations and use them for personal reasons? I don't have to tell you how often this has been documented, and how much more often it must occur in instances that go undocumented.
  • There can never be an absolute guarantee that an individual employee will never intentionally violate a law or policy. That is true of every profession in which society entrusts individuals with significant authority and access to sensitive information.

  • The appropriate question, therefore, is what safeguards exist to deter misuse, identify it when it occurs, and hold the person accountable. In the case of ALPR, those safeguards include mandatory training, specifically authorized users, individual login credentials, required documentation of queries, case or identifying numbers, audit trails, supervisory oversight, and periodic audits. The POSTC Model Policy also expressly prohibits personal use of ALPR systems and data.

  • Intentional misuse is not a minor policy violation. Depending upon the circumstances, misuse can result in administrative discipline, termination, decertification, civil liability, and potentially criminal prosecution. The existence of a system capable of detecting misuse is therefore a critical part of protecting the public.
How frequently is ALPR system activity audited, and who conducts those audits?
ALPR activity is audited quarterly by the Office of Professional Standards. The audits are conducted under the direction of the lieutenant responsible for Professional Standards and Internal Affairs, with additional oversight through the Department’s command structure, including a captain, deputy chief, and ultimately the Chief of Police.
Why is there no impartial third-party agency tasked with monitoring this system for abuse and conducting audits of its use? Are we expecting the police to police themselves?
  • Police officers have access to numerous forms of highly sensitive information through criminal justice information systems, DMV records, investigative reports, body-worn cameras, and other systems used in the normal course of law enforcement. ALPR information is subject to many of the same fundamental safeguards, in addition to specific safeguards established for ALPR use.

  • Those safeguards begin with legally restricted access and continue through department policies, specifically authorized and trained users, individual credentials, required documentation, and detailed audit trails. Under the current POSTC ALPR Model Policy, ALPR queries require the user to document the parameters and reason for the search, along with a case number or other identifying number. The policy also requires the department's ALPR administrator to conduct a quarterly audit of the system, including review of audit logs to determine whether queries were made for authorized and legitimate purposes.

  • As with many of the functions we perform involving sensitive information, there is a robust system of internal accountability. Police officers are entrusted with access to information and authority that carries significant legal and ethical responsibilities. We take training, education, and compliance with federal and state law very seriously. Mandatory documentation and audit trails are fundamental to everything from information-system access to use of force.

  • That does not mean accountability ends with the Chief of Police. Police departments operate within a larger system of oversight that includes POSTC, prosecutors, the courts, municipal oversight, and other state and federal authorities where applicable. POSTC has authority over the certification and decertification of Connecticut police officers, and Connecticut's recently enacted ALPR legislation has established additional statutory requirements concerning the use, retention, and sharing of ALPR information.

  • It is also important to recognize that this is an evolving area of law and public policy. On August 7, 2026, Governor Ned Lamont called for a statewide review of safety cameras and ALPR technology, citing legitimate public concerns about privacy. He directed POSTC to develop guidance addressing permissible uses, how long information may be retained, how information may be shared, and what policies should be in place before these technologies are implemented. He also urged municipalities to pause installation of any new cameras and ALPRs until that guidance is completed.

  • The Governor's action should not be interpreted as a finding that existing municipal ALPR programs are unlawful. Rather, it reflects the fact that this technology is evolving faster than the policy framework surrounding it, and that additional clarity and safeguards are appropriate. That is a position with which a police department and the public can reasonably agree.
What happens if an audit identifies an unauthorized search, disclosure, or other misuse of the ALPR system?
Unauthorized use of the ALPR system or its data is treated as a serious misuse of a law enforcement information system, comparable to misuse of the COLLECT system. Depending on the circumstances, violations may result in disciplinary action up to and including termination, decertification, and potential criminal investigation or arrest.
According to the PD website, data may not be retained for more than 30 days, unless it “pertains to a criminal, administrative, or civil matter.” Wouldn't you agree that this is a pretty big basket, encompassing almost anything?
  • The 30-day provision is not simply a Town-created exception. The current POSTC ALPR Model Policy provides that ALPR data should not be retained for more than 30 days unless it pertains to a criminal, administrative, or civil matter. In anticipation of amended POSTC guidelines, the Fairfield Police Department has already lowered its retention period to 21 days.

  • The purpose of that exception is evidence preservation. Once information has become relevant to an identifiable matter, it may need to be preserved beyond the ordinary retention period rather than automatically deleted while an investigation, administrative proceeding, litigation, or other matter remains pending.

  • The phrase “civil matter” is admittedly broad, and it is reasonable for the public to ask how that provision is interpreted and applied. However, it should not be understood to mean that an officer can simply designate someone's historical movements as a “civil matter” in order to retain them indefinitely. The retention exception should be tied to an identifiable matter and governed by applicable law and departmental policy.

  • For example, if ALPR information lawfully obtained during an investigation subsequently becomes relevant evidence in a civil proceeding arising from the underlying incident, preservation of that particular information could provide a legitimate reason for retaining it beyond the normal retention period. The fact that a matter is civil, however, does not by itself create unlimited authority to retain ALPR information.
  • This is also an area in which additional statewide guidance would be useful. Governor Lamont's August 7, 2026 request to POSTC specifically asks the Council to address how long ALPR information may be stored and how it may be used and shared.
Can outside law enforcement agencies directly search or query Fairfield’s ALPR data?
No. Fairfield does not permit outside agencies to directly search or query its ALPR data.
Can federal agencies directly access or query Fairfield’s ALPR data?

No. Federal agencies do not have direct query access to Fairfield’s ALPR data.

Could a federal agency, including an immigration-enforcement agency, access Fairfield’s ALPR data indirectly through another state, local, regional, or partner-agency system?
No. Fairfield’s ALPR data is not available through another system or network that would allow a federal agency to indirectly query Fairfield’s database. Fairfield does not provide outside agencies with direct or indirect search access to its ALPR system.
Must Fairfield affirmatively approve each agency that can search its data, or can access arise through a regional network, reciprocal arrangement, vendor setting, or another participating agency? 

All sharing requests come through the Office of the Chief of Police however we do not permit outside agencies to query our data.

If someone from another agency searched Fairfield’s ALPR data, would Fairfield be able to identify the person, their employing agency, the reason for the search, case number, plate searched, records viewed, and any information downloaded or exported?
Outside agencies are not permitted to search or query Fairfield’s ALPR system. As a result, outside-agency searches of Fairfield’s database do not occur under the Department’s current access configuration.
