# Automatic License Plate Reader (ALPR) A camera-and-software system that **photographs vehicle license plates, performs optical character recognition, timestamps and geolocates each read, and compares the read against one or more "hot lists" of plates of interest**. Each read is also stored as a searchable database record; the database can be queried by plate, by location, by time window, or by other vehicle features. In law-enforcement use, hits against hot lists generate real-time alerts; the database itself enables retrospective investigation. Van Buren's first rolling production documents recurring six-LPR/two-video Flock billing, two grant-backed LPR additions, three ARDOT-permitted sites, and Policy 2.36. The policy requires search reasons and logs, secondary-dissemination records, six-month reports, and a default thirty-day purge; those operational records are not in the rolling package ([[Van Buren Flock Invoices 2023-2026]]; [[Van Buren ARDOT Flock Permits 1866 and 1876]]; [[Van Buren License Plate Reader Policy]]). ## How it appears in the corpus - **Flock Safety Falcon ®** is the specific ALPR product Conway PD has deployed under the [[Flock Safety Order Form and Contract]]. Twenty cameras, fee-bundled into the $60K/year recurring price. - **Genetec** is the pre-Flock vendor — first identified in [[AR - Conway PD - Welcome to Flock! (3) - Flock Kickoff Slide Deck]] ("Genetec cams are LPR"), and now documented by the 2022 procurement estimate produced in `PD-2026-477`: a **Genetec AutoVu** platform (Genetec Security Center 5.10 with the AutoVu LPR module), sold and installed by [[SkyCop, Inc.]], a Memphis surveillance-systems integrator. Six "stationary" cameras, installed since 2023, running on a server "owned and operated by the Conway Police Department." See [[SkyCop Estimate for Pre-Flock Genetec LPR System]] and [[LPR Report First Half 2025]]. - **Axon Fleet 3** is a *mobile* ALPR system — a license-plate-recognition function activated on in-car patrol cameras rather than fixed roadside cameras — trialed by the [[Fayetteville Police Department]] from February to April 2026. Axon is the second non-Flock ALPR vendor in the corpus, after Genetec. See [[Axon Fleet 3 ALPR Trial]]. - The **[[Pulaski County Sheriff's Office]]** operates a Flock ALPR system. Its January 1 – May 19, 2026 six-month practice-and-usage report — compiled under Ark. Code § 12-12-1805 — records 1,422,898 plates scanned and 2,092 confirmed alerts, with 79% of alerts driven by other agencies' custom hot lists shared into PCSO's networks ([[PCSO ALPR Six-Month Practice and Usage Report]], [[PCSO ALPR Offense-Type Search Usage]]). - The **[[Cabot Police Department]]** production documents eight fixed Flock points and one dated Flex point, a local policy requiring visual and ACIC/NCIC confirmation before an alert-based stop, seven six-month public reports, and a reported Mobile Axon LPR period that ended by early 2025 ([[Cabot Flock Camera Locations]]; [[Cabot LPR Policy 305.1]]; [[Cabot Semiannual LPR Reports]]). - The **[[Hot Springs Police Department]]** production documents a legacy 2021 Vigilant/LEARN service form and an unsigned six-key L5Q form, followed by a 2025 non-binding Flock quote and a 2026 ten-site `LPR + Video` plan. It does not establish current operation of either system ([[Hot Springs Vigilant Agreements and Legacy ALPR]]; [[Hot Springs P1977 Flock Camera Plan]]). - The **[[Saline County Sheriff's Office]]** production documents a fully executed nine-Falcon Flock order, a nine-row installed-camera screen, a local policy requiring individual credentials, documented search reasons, alert verification, written quarterly audits, and 30-day vendor purging. The production supplies no coordinates or six-month § 12-12-1805 report ([[Saline County Flock Inventory Contract Invoices and Sharing Printout]]; [[Saline County SharedNetworks and Deployment Printouts]]; [[Saline County Camera Policies UAV Log and Audit Printouts]]). - The **[[Lonoke County Sheriff's Office]]** production documents three Flock LPR-plus-fixed-video bundles and three standalone LPRs, a customer-signed $24,000 annual order, six exact Permit-1924 plan points, and Policy 10.16. The live vendor portal crosschecks the product count as nine total cameras and six LPRs, while installation and current site-level operation remain unverified ([[Lonoke County Flock Contract ARDOT Permit and Camera Locations]]; [[Lonoke County ALPR Policy 10.16]]). - The **[[Jonesboro Police Department]]** completion package documents five ARDOT permit packets covering eleven ALPR points, monthly Flock and Axon activity workbooks, and Policy 715.02. The policy treats LPR data and media as agency property and requires documented search reasons and secondary dissemination; the two vendors' log schemas do not support a direct accuracy comparison ([[Jonesboro ARDOT ALPR Permit Packets P1881 P1889 P1967 P1969 P1982]]; [[Jonesboro Flock and Axon ALPR Activity Logs 2025-2026]]; [[Jonesboro UAS RTCC and ALPR Policies 714 and 715]]). - The **[[North Little Rock Police Department]]** production documents 12 installed and 20 pending Flock sites, a 34-row SkyCop-titled list, Genetec/SkyCop procurement and renewals from 2018 through 2025, and 49,569,171 scans across Flock and SkyCop for January-June 2026. NLRPD therefore shows parallel fixed-ALPR systems rather than a single-vendor deployment ([[North Little Rock Flock Camera Inventory]]; [[North Little Rock SkyCop LPR Location List]]; [[North Little Rock SkyCop and Genetec Procurement 2018-2025]]; [[North Little Rock January-June 2026 ALPR Practice and Usage Report]]). - The **[[Rogers Police Department]]** record documents a ten-camera Flock pilot alongside a signed 110-Fleet-3/ten-Outpost Axon base quote, five operational `P1957` Outpost sites, and a signed five-Fleet-3 add-on scheduled after the archive endpoint. Its 2026 signed report page gives 20,943,644 Flock scans and 5,554,221 Axon scans, but a competing editable version carries materially different alert totals ([[Rogers Axon Outpost and Fleet 3 Records]]; [[Rogers LPR Reports and Audit 2025-2026]]; [[T056 - Rogers 2026 LPR Report Version and Date Divergence]]). - Conway PD's semi-annual LPR reports disclose **H1 2024 — 6,316,810 reads / 2,007 hits / 3 logged successful outcomes** on the six pre-Flock cameras, and **H1 2025 — 7,458,633 reads / 3,327 hits / 4 logged successful outcomes** on the 14-camera (6 Genetec + 8 Flock) system. The two figures come from two versions of the H1 2025 report produced in different productions; see the contradiction callout on [[LPR Report First Half 2025]] and [[LPR Report First Half 2025 (PD-2026-477 Copy)]]. - **CPD Policy 800-32** is the local policy governing ALPR use. Effective 2013, revised 1/18/2023 (R3) under Chief William Tapley. See [[CPD Policy 800-32 — License Plate Reader Vehicle Operations]]. - **The Arkansas Automatic License Plate Reader System Act** (Ark. Code Ann. §§ 12-12-1801 – 1808) is the state statute governing ALPR use, retention, sharing, public reporting, and disclosure; Conway PD invokes it in `PD-2026-477` to withhold operational records. See [[Arkansas Automatic License Plate Reader System Act]]. - The technical model — read + hot-list-comparison + database-storage — is foundational to every other concept in the investigation: hot lists, network sharing, federal LE data access, and audit logs are all downstream of the per-read data structure. - The **[[Jacksonville Police Department]]** supplement adds a fully executed eight-Falcon order, a fourteen-LPR device-health inventory, and a deployment tracker labeling all fourteen LPR rows installed. The missing six-camera expansion order remains open rather than inferred ([[Jacksonville Flock LPR Contract and Renewal Invoices]]; [[Jacksonville Flock Device Health and Deployment Tracker]]; [[T042 - Jacksonville Fourteen-LPR Inventory vs Eight-LPR Executed Order]]). - The **[[West Memphis Police Department]]** first production documents customer-signed copies of a six-LPR order, first-camera-validation billing, and three exact Permit-1987 points. The vendor signature, all-six installation record, and permit closeout remain unproduced ([[West Memphis Flock Order and First-Validation Invoice]]; [[West Memphis ARDOT Permit 1987 and Camera Locations]]). ## Stakeholders - **Camera-owning agency** ([[Conway Police Department]]) — owns the local fleet, controls the platform admin role. - **Vendor** ([[Flock Safety, Inc.]] for the current 20-camera fleet; the legacy 6-camera fleet is a Genetec AutoVu platform supplied by the integrator [[SkyCop, Inc.]]) — provides hardware, software, cloud (Flock) or on-premises (Genetec/SkyCop) storage, and the platform administration tooling. - **Data-sharing counterparties** — any organization that has been configured as a sharing-partner in the platform; see [[SharedNetworks 2025-12-17 Snapshot]]. - **Public** — under CPD Policy 800-32's Section D.2 and Ark. Code § 12-12-1805, the semi-annual LPR statistical report is compiled "into a format sufficient to allow the general public to review" it and kept for 18 months; see [[LPR Report First Half 2025]]. ## Timeline - 2013 — the Arkansas Automatic License Plate Reader System Act is enacted (Act 1491 of 2013); see [[Arkansas Automatic License Plate Reader System Act]]. - 2025-04-16 — Act 668 materially amends the Arkansas ALPR Act, adding authorized uses and tiered retention/update/sharing/reporting/policy/enforcement provisions. - 2013-08-30 — CPD Policy 800-32 first effective (text in [[AR - Conway PD - Welcome to Flock!]]). - 2022-04-11 — SkyCop, Inc. estimates the Genetec AutoVu LPR system for Conway PD ([[SkyCop Estimate for Pre-Flock Genetec LPR System]]). - ~2023 — six Genetec cameras installed (per [[LPR Report First Half 2025]]). - 2023-01-18 — Policy 800-32 R3 signed by then-Chief William Tapley. - 2024-12-13 — Chief Harris pivots Flock procurement to asset-forfeiture funding after Council cuts the cameras from 2025 budget (see [[Morning - Procurement Pivot Thread]]). - 2025-01-23 — Flock onboarding meeting. - 2025-04 — Earliest Flock audit log dated. - 2025-07-01 — Burningham's semi-annual LPR report (two versions of which are in the corpus). - 2025-12-17 — Flock platform cutover (audit-log schema change; SharedNetworks snapshot). - 2026-01-22 — Escambia FL hot-list share to Conway. - 2026-03-12 → 2026-04-08 — Home Depot AR state-wide camera-share rollout to Conway. - 2026-03 → 2026-04 — Conway PD produces a 5,929-row federal-tagged Flock search export whose network identities and results are not included ([[Federal Searches CSV]]). - 2026-04-17 — Joshua files FOIA `PD-2026-354`. - 2026-04-20 — Burningham relays Conway City Council questions about Flock data security to Flock CSM. - 2026-05-22 — Conway PD completes `PD-2026-477` and withholds the network-sharing, federal-search, hot-list, and pre-April-2025 audit-log categories ([[2026-05 Conway PD PD-2026-477 Withholding Response]]). - 2026-05-22 — Pulaski County SO releases its § 12-12-1805 six-month ALPR usage report on FOIA `#26-808`: 1,422,898 plates scanned, 2,092 alerts ([[2026-05 Pulaski County SO ALPR FOIA Response]]). - 2026-07-27 — Saline County's first production enters the corpus with nine-camera procurement and deployment records, Policy 5.27, and partial audit printouts, but no § 12-12-1805 report. - 2026-07-28 — Lonoke County's first production enters the corpus with a six-LPR/three-video order, six exact permit-plan points, Policy 10.16, and a portal-directed partial disposition. - 2026-05-29 — Rogers's five `P1957` Axon Outpost sites are reported “all up and running.” - 2026-07-03 — Rogers's first Professional Standards LPR audit and signed report package is dated, while its report page retains unresolved date/period/version conflicts. ## Notes ### Jacksonville fixed, mobile, and integrated-video boundary Jacksonville's location export distinguishes 14 `LPR Camera` rows from 101 `Video Integration`, two `Video Camera`, and nine `Compute Box` rows. The 117 camera rows all carry exact coordinates, but the integrated-video rows do not identify the underlying camera make or owner ([[Jacksonville Flock and Wing Camera Location Export]], pp. 1-3). The separate VehicleManager report lists ten mobile systems, three standalone systems, and 37 camera-channel lines. Policy 10-28 expressly covers Motorola LPRs and AVA Quad cameras with LPR detection, showing why a camera count and an ALPR count cannot be collapsed without the source's device-type field ([[Jacksonville VehicleManager System and Data-Sharing Reports]], p. 1; [[Jacksonville LPR Policy and Retention Settings]], p. 1). ### Capability and error boundaries Current Flock materials describe plate-optional vehicle searching, natural-language retrieval, non-facial people search, and association/pattern products; those functions are separated at [[Flock Search and Association Analytics]]. Their presence in a catalog does not establish that an Arkansas tenant licensed or enabled them. The LRPD record does establish procurement of “vehicle fingerprint software,” while Conway's record establishes that vehicle-fingerprint information existed in the platform's Network Audit context. Hardware evidence is equally bounded: teardown components, patents, FCC records, catalog labels, and CVEs apply to named devices, versions, builds, or claimed embodiments. They are not a universal bill of materials for Arkansas cameras; see [[Flock Hardware Evidence Boundaries]]. Finally, “accuracy” must identify the layer being measured. OCR, state/jurisdiction recognition, hot-list freshness, physical-plate verification, occupant association, and outcome attribution can fail independently. The Sherwood misread and the LAPD mixed-program audit are reconciled at [[ALPR Error Layers and Outcome Measurement]]. - The term "ALPR" covers four distinct layers: (a) image capture/OCR, (b) hot-list comparison and alerts, (c) the retrospective database, and (d) plate-optional or association analytics. Each layer has different errors, retention, sharing, and audit consequences. - No current independent public per-SKU confusion matrix was located for Flock OCR or its named search/association functions. Marketing examples and case outcomes cannot substitute for precision, recall, false-match, and miss rates stratified by model/build and operating conditions. - The constitutional cases are fact- and posture-specific; no audited authority supports a nationwide categorical rule for all ALPR configurations. See [[ALPR Fourth Amendment Law Is Fact-Bound and Unsettled]]. - ALPR-policy literature (ACLU, EFF, Brennan Center) is a useful reference for any later treatment of policy norms for ALPR retention, sharing, and oversight. ## August 2026 Bryant, Bentonville, and Van Buren additions - [[Bryant Police Department]] is documented with a nine-LPR order, seven exact Permit 1899 plan points, and 2,039 unique search-audit rows ([[Bryant Flock Procurement Contract and Payment]]; [[Bryant Flock Locations and ARDOT Permit 1899]]; [[Bryant Flock Search Audit June 2025 to March 2026]]). - [[Bentonville Police Department]] supplies five healthy Flex LPR rows whose deployment tracker says `INSTALLED` / `Complete`; the tracker does not provide calendar installation dates ([[Bentonville Native Camera Inventory and Deployment Tracker]]). - [[Van Buren Police Department]] supplies eight current LPR rows, two marked offline. F#008's current `44th St` label and point conflict with the Permit 1876 plan's `46th St` label and point ([[Van Buren Flock Locations and Health August 2026]]; [[T047 - Van Buren F008 46th Street Permit Plan vs 44th Street Health Export]]). - [[Rogers Police Department]] supplies combined Flock/Axon operational reporting and two preserved 2026 report versions. The signed page's 6,007 Flock alerts and the editable file's 41,339 remain unreconciled ([[Rogers LPR Reports and Audit 2025-2026]]).
