Harris County Sheriff and several constable precincts deploy Flock Safety automated license plate readers across unincorporated neighborhoods. Texas has no specific ALPR statute. Use is governed by the Sheriff's general policy, the Public Information Act, and constitutional limits on warrantless mass surveillance.
Harris County Sheriff's Office and Constable Precincts 1, 4, and 5 partner with Flock Safety to install solar-powered ALPR cameras at neighborhood entrances and major intersections. Cameras log plate numbers, vehicle make, color, and unique features for 30 days under standard Flock retention. Texas has no analog to California SB 34 or Virginia's ALPR transparency act. Use is shaped by HCSO general orders, the Texas Public Information Act, and Carpenter v. United States limits on warrantless tracking. The Texas Attorney General opined in 2023 that mass ALPR scanning does not require a warrant but data sharing across agencies must comply with Government Code Chapter 411 and CJIS rules.
Misuse of ALPR data by deputies can trigger termination, criminal charges under Penal Code 39.06 (misuse of official information), and civil liability under Texas Civil Practice and Remedies Code Chapter 101 for invasion of privacy or constitutional torts.
