Harris County Sheriff | Plate recognition software and the LEARN database
Every year since 2021, Harris County has approved a sole source exemption from competitive bidding to buy subscription access to Vigilant Solutions plate recognition software, and a smaller line connecting county plate cameras to Vigilant's LEARN database.
At a glance
- Current subscription
- $158,120, for 8 August 2026 to 7 August 2027, approved 11 June 2026 [15]
- Every year since
- 2021, when the first item in the county record we read was already a renewal at $140,600. The figure has run $140,600, $146,200, $152,040, $158,120 [1] [3] [5] [10]
- How it is bought
- A sole source exemption from the competitive bid requirements, every time, each item carrying the justification "Exempt - Sole Source" [1] [3] [5] [10] [13] [15]
- The database connection
- A separate line, $15,210, for "software license, support, maintenance, and warranty for license plate camera connection to LEARN Database" for the Sheriff's Office, first seen 29 August 2023 and renewed 19 September 2024 [7] [12]
- Approved as presented
- All nine items. None appears on the County Clerk's results list for its meeting [2] [6] [16]
- What the subscription reaches
- not stated. The items say "subscription-based access to license plate recognition software" and name no data source, coverage or query scope [15]
- Whether county plate reads go into LEARN
- not stated. The item describes a connection from county plate cameras to the database and does not say which way data moves [7]
How it happened
- Procurement
Already a renewal when the record opens
The Court approves a sole source exemption with Vigilant Solutions, LLC for access, maintenance, support and warranty for the license plate recognition data subscription for the Sheriff's Office, $140,600, through 31 July 2022. The Legistar record begins in 2021, so this is the earliest item available, not necessarily the first. [1] [2]
- Decision
$146,200, and now for the whole county
The renewal names Harris County rather than the Sheriff's Office, for 1 August 2022 to 31 July 2023. Approved as presented. [3] [4]
- Decision
$152,040, with four renewal options attached
A sole source exemption and agreement for subscription-based access to license plate recognition software, with four one-year renewal options, which is the structure the later years run on. Approved as presented. [5] [6]
- Expansion
County cameras are connected to the LEARN database
Three weeks after the subscription renewal, a separate $15,210 agreement for "software license, support, maintenance, and warranty for license plate camera connection to LEARN Database" for the Sheriff's Office. LEARN is Vigilant's plate data platform. Approved as presented. [7] [8]
- Decision
Amended and renewed on the same agenda
Item 245 adds $6,080 to the expiring subscription for additional services; item 248 renews it at $158,120 for 2024-25. Both approved as presented. [9] [10] [11]
- Decision
A renewal ratified after the fact
The Court approves a ratification of a sole source exemption renewal option at $158,120 running through 7 August 2026. A ratification is approval given after the thing has already happened; the period it covers had begun the previous August. Approved as presented. [13] [14]
- Decision
Renewed to August 2027
A sole source exemption and renewal option at $158,120 for 8 August 2026 to 7 August 2027. Approved as presented. [15] [16]
A second plate reader system, with no cameras in it
Harris County’s Flock contract buys cameras. This one does not.
Every year since at least 2021, Commissioners Court has approved a payment to Vigilant Solutions, LLC for what the items call subscription-based access to license plate recognition software. There is no hardware in the line. The county is buying the ability to look something up.
The figures are steady and rising: $140,600 through July 2022, $146,200 for 2022-23, $152,040 for 2023-24, and $158,120 in each of 2024-25, 2025-26 and 2026-27. The most recent renewal, approved on 11 June 2026, runs to 7 August 2027.
The other line
Three weeks after the 2023 subscription renewal, the Court approved a second, much smaller agreement with the same company: $15,210 for
software license, support, maintenance, and warranty for license plate camera connection to LEARN Database
for the Sheriff’s Office. It was renewed in September 2024.
LEARN is Vigilant’s plate data platform. A connection between county plate cameras and that platform is the interesting half of this county’s plate reader story, and it is also the half the record says least about. The item does not say which direction data flows, how long anything is kept, or who else can search it.
Sole source, every year
Each of these items carries the same justification on its face: “Exempt - Sole Source”, an exemption from the competitive bid requirements under Texas county purchasing law.
That is a normal category. It exists because some things genuinely have one supplier, and a proprietary software platform is a common example. What it means in practice is that this purchase has not been competitively bid in any year covered by the readable record, and the reasoning for that sits in a written justification the Purchasing Agent holds rather than in anything published with the agenda.
One year is worth noting separately. In December 2025 the Court approved a ratification of the renewal, for a period that had begun the previous August. Ratification is approval given after the fact. The item was approved as presented, like every other one.
What a reader should take from this
The cameras are the visible part of plate reader surveillance, and they are what a resident can photograph on a pole. This line is the other part: an annual six-figure subscription, bought without competition, that lets the county query plate recognition data, plus a connection wiring county cameras to a company’s database.
None of it produces a camera anyone can point at, and all of it was approved as presented.
What we do not know
- What the subscription actually reaches. The items say "license plate recognition software" and never describe the data behind it.
- Which way data moves through the LEARN connection, and who can query county plate reads once they are there.
- Why this purchase has been a sole source exemption from competitive bidding every year since at least 2021. The written justification is a document the Purchasing Agent holds.
- When the subscription began. The first item in the readable record, in September 2021, is already a renewal.
