The Houston Police Department is reviewing officers’ use of its automated license plate reader network. The HPD Flock camera investigation follows an audit that identified activity requiring further examination.
HPD has not disclosed how many officers or searches are under review. The department also has not described the activity that triggered the investigation.
HPD Flock Camera Investigation Places Accounts on Hold
HPD said it regularly reviews personnel use of automated license plate recognition systems. During the latest audit, the department identified activity that needed additional investigation.
Some officers’ accounts have been placed on hold during the review. HPD said its Internal Affairs Division will investigate any policy violations that auditors discover.
The department has not announced whether any employees face administrative leave or other disciplinary action. It also remains unclear when the investigation will conclude.
What HPD Policy Allows
Flock cameras photograph license plates and collect details such as a vehicle’s location, direction and time of travel. Authorized officers can search those records while investigating crimes or locating vehicles connected to missing people.
Under HPD General Order 400-29, employees must complete approved training before using an automated license plate recognition system. Officers may use the data only for “bona fide criminal investigations.”
The policy prohibits officers from using the system for personal, civil or administrative purposes. Employees also cannot share information with unauthorized people.
Violations may result in discipline up to indefinite suspension. The order also requires the department’s ALPR manager to conduct a semiannual audit of randomly selected transactions.
Flock Cameras Face Wider Scrutiny
The HPD review comes amid growing concern about Flock camera use across the Houston region. Several local agencies have investigated officers or restricted access following questionable searches.
The Harris County Sheriff’s Office suspended three deputies’ access while conducting an administrative review. The agency also began requiring descriptive case codes for license plate searches, according to ABC13.
In Deer Park, an internal audit found that an officer violated department rules governing law enforcement technology. The department imposed disciplinary action but did not identify the officer or explain the searches involved.
Other investigations have emerged in Baytown, Pasadena, Fort Bend County and Katy. The circumstances differ, but several cases included allegations that officers conducted searches unrelated to legitimate police work.
Technology Offers Benefits and Privacy Concerns
Law enforcement agencies say Flock cameras help locate stolen vehicles, identify suspects and find missing people. A 2025 presentation to Houston City Council said HPD used the technology daily in burglary, homicide and organized retail theft investigations.
However, privacy advocates have questioned how agencies monitor searches and share records. Flock Safety has announced additional safeguards for law enforcement customers. Planned changes include mandatory auditing tools designed to flag unusual search activity and temporarily block accounts pending review.
The HPD investigation could clarify whether officers followed existing rules and whether stronger oversight is needed. Transparent findings will help Houston residents evaluate how the City of Houston balances public safety, employee accountability and personal privacy.
