Flock Safety is one automated license plate reader (ALPR) system, not a universal policy for every agency that uses it. Its vendor-described platform records plate images, vehicle characteristics, timestamps, and camera-location identifiers. Rekor Scout takes a different approach by adding recognition software to compatible cameras, while Axon Fleet 3 is an in-vehicle system. Those differences affect deployment and product features; who may search the records, how long they remain, and whether they are shared are also shaped by customer settings and applicable law.
There is no independent, apples-to-apples evidence here to rank these vendors on recognition accuracy, total cost, or privacy performance. To compare a real deployment, look beyond the product name: check what is captured, who can search it, which agencies have access, the retention configuration, and how searches and exceptions are overseen.

What differs between Flock, Rekor Scout, and Axon Fleet 3?
The main product distinction is how each system is deployed. Flock describes an ALPR camera network; Rekor Scout is software intended to work with many compatible existing cameras; Axon Fleet 3 is an in-vehicle camera system. Their vendor-published descriptions are not a standardized comparison, and the table separates documented capabilities from settings an agency must verify locally.
| System | Deployment and documented functions | Data and retention information | What is not established by these sources |
|---|---|---|---|
| Flock Safety ALPR | Flock describes records containing plate images, vehicle characteristics, date and time, and camera-location identifiers. The company says this ALPR system does not use facial recognition. Flock says agencies manage accounts and access and that searches are logged. Flock Safety Trust Center | Flock’s current materials describe seven days as the recommended or usual default for new configurations, while customer settings, local law, and previously established retention periods may differ. Flock Safety Press Center | Recognition accuracy and a specific agency’s current retention or sharing configuration are not stated by the cited vendor pages. |
| Rekor Scout | Rekor describes Scout as software that can add plate and vehicle recognition to many IP, traffic, or security cameras. It supports searches using full, partial, or missing plate numbers and vehicle attributes, and real-time alerts using hotlists. Rekor Scout product page | Rekor describes cloud-hosted and on-premises options and configurable retention. Actual deployment and retention depend on the chosen implementation. | An independent accuracy comparison with Flock or Axon is not stated on the cited product page. |
| Axon Fleet 3 ALPR | Axon describes Fleet 3 as an in-vehicle ALPR system with a dedicated 4K image sensor and AI-enabled plate-reading software. Axon Fleet 3 ALPR FAQ | Axon says agencies can configure retention for hit and read records. | It is not a direct fixed-camera equivalent to Flock’s camera network. The cited FAQ does not state a comparable accuracy figure or a universal retention period. |
These are vendor-described capabilities, not results from a shared test protocol. In particular, a 4K sensor specification, support for partial-plate searches, and a vendor’s description of its data practices do not by themselves show how often a system identifies a plate correctly in a particular deployment.

What information does an ALPR system record?
An ALPR system is designed to recognize vehicle plates and associate a read with context such as time and location. Flock says its ALPR records include plate images, vehicle characteristics, timestamps, and camera-location identifiers; it also says the system does not collect facial-recognition data. These are Flock’s descriptions of its product, not a guarantee about every data source or camera function an agency may operate alongside it. Flock Safety’s data privacy statement
Rekor describes recognition of plates and vehicle attributes, including searches based on attributes or incomplete plate numbers. Axon’s cited Fleet 3 description focuses on its dedicated camera sensor and plate-reading software. The available product descriptions do not establish an identical set of captured fields across all three systems.
ALPR should not be conflated with facial recognition: a plate read concerns a vehicle and its plate, not proof of who was driving or riding in it. Nor does a plate record alone establish why a vehicle was at a location. The practical privacy impact depends on what information is retained, how it can be searched, how broadly access is granted, and how long records remain available.

Who can see the records, and can Flock share data with other agencies?
Flock says customer agencies control account access and decide whether to share records with other agencies. The company states: “Agencies own and control the data generated by their cameras, and data sharing is not enabled by default.” Flock Safety Press Center That is the vendor’s description of its policy; it does not identify the sharing settings for a particular city, county, school, business, or neighborhood deployment.
Sharing is not impossible: a customer can enable it. Historical reporting also shows why an agency’s active sharing list matters. The Associated Press reported past federal-agency access through privately operated ALPR networks, including Flock, and reported that Flock had paused certain federal pilot programs at the time of its statement. That account concerns a particular period; it does not establish which agencies can search a given system now or whether any specific local deployment shares records. Associated Press report on Border Patrol access to ALPR networks
For any named deployment, distinguish at least three questions: which local employees or users have accounts, which outside agencies can search or receive data, and what approvals or purpose limits apply to those searches. A general vendor statement cannot answer those local questions.

How long do police keep ALPR data?
There is no single retention period for every Flock deployment. Flock’s current materials describe seven days as the recommended or usual default for new configurations, and say records are automatically deleted at the end of the configured period. The company also says local law and customer policy can affect retention and that existing customers keep previously established periods. The materials do not establish that every installed camera or customer account has moved to seven days. Check the agency’s current configuration rather than assuming a vendor-wide period. Flock Safety Trust Center and Flock Safety Press Center
Rekor describes retention as configurable, with cloud and on-premises deployment options. Axon says an agency can configure retention for Fleet 3 hit and read records. Neither vendor description supplies one universal period for all customers. A local policy or contract may also specify how records connected to an investigation are preserved; request that rule separately from the ordinary deletion schedule.
What can local records show that a vendor page cannot?
Local policy, contract terms, configuration records, and oversight documents are the evidence for how a particular system is used. For example, an official City of Oxnard review says its police department used Motorola’s Vigilant Solutions platform from October 2017 through February 2023 and later reviewed agency sharing through Flock. It also discusses California limits on sharing ALPR information with out-of-state and federal agencies. This is a local example, not a description of every Motorola system, every California agency, or national law. City of Oxnard ALPR Data Sharing Review

That example illustrates why “which vendor?” and “under what rules?” are separate questions. A department can change platforms while retaining its own policies and legal obligations; a platform’s available controls do not reveal which ones the agency has enabled.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to compare a specific local ALPR deployment
Ask the agency or system operator for current, deployment-specific records. A useful request includes these items:
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute- Policy and contract: Obtain the current ALPR policy, the signed contract, and amendments. Look for permitted purposes, prohibited searches, user eligibility, and responsibilities for managing data.
- Captured fields and equipment: Ask what the system records, whether it stores plate images or other vehicle details, which cameras are connected, and whether any additional video functions are in use.
- Retention settings: Request the configured deletion period for ordinary records, when that period began, and how records linked to an investigation may be preserved or deleted.
- Sharing and access: Request the current list of agencies or external users able to search or receive data, how sharing was authorized, what limits apply, and how access is removed when it is no longer approved.
- Search rules and audit: Ask what counts as a valid search reason, whether a supervisor must approve a search, what is recorded in audit logs, and who reviews those logs and how often.
- Applicable law and public oversight: Check state and local rules, including any limits on interstate or federal sharing, and look for transparency reports, public records, or documented access reviews.
If an agency cannot provide a particular item, that is different from proof that the control does not exist. Ask who is responsible for it—the agency, vendor, or another authority—and what public record or review process can verify it.

Can the available evidence show which system is best?
No fair cross-vendor ranking on accuracy, total cost of ownership, or privacy performance is established by the cited material. The product pages describe features, not results from a common independent test. A meaningful procurement comparison would need comparable evidence such as independently measured recognition and false-positive rates under relevant conditions, uptime, full costs, and the local controls actually configured.
Flock’s homepage reports “27 missing people located every day using Flock in 2025.” That is a company-published impact figure, not an independently verified comparative statistic, so it cannot establish that Flock outperforms another system. Flock Safety homepage
