We haven't gathered what Miller County's agencies use yet — not gathered, not hidden. The fastest way to find out is to ask: the sheriff's office and city police can say which tools they run, what their written policies are, and how long they keep the data. Purchases above a set amount also appear in county and city budgets and meeting minutes.
Fixed or car-mounted cameras photograph passing license plates and log the plate, time, and place. Police can search past reads to track a car after a crime, or get an alert when a car on a 'hot list' (stolen, wanted, missing person) drives by. With Flock, the agency that owns the cameras decides who can search its data, including other agencies.
How long data is kept: Flock's default is to delete reads on a rolling 30-day basis, unless a customer's policy or contract says otherwise. In August 2026 Flock urged agencies to cut this to 7 days (a suggestion, not a rule). Arkansas law caps most retention at 150 days.

Small cameras worn on an officer's uniform record video and sound of contacts with the public. Each agency's policy says when officers must turn them on, who may watch the video, and when the public can get a copy.
How long data is kept: Set by state law and agency policy. Texas requires agency policies to keep video at least 90 days. Florida requires recordings to be kept under its public records retention rules.

A real-time crime center is a room inside a police agency where staff watch live feeds and data (cameras, plate readers, 911 calls, records) and pass details like suspect car descriptions to officers on the way to a call. The U.S. Justice Department describes them as central hubs for crime information.
How long data is kept: Varies by agency; no common standard confirmed.

Software compares a face from a photo or video (such as a store camera still) against large photo collections and returns possible matches for an officer to check. A 2023 federal audit found seven federal law enforcement agencies used these services, and six of them ran about 60,000 searches before requiring any training.
How long data is kept: Not confirmed; depends on the vendor and agency.

Microphones placed around a neighborhood listen for sounds like gunfire and send police an alert with an estimated location, often before anyone calls 911. Chicago signed a three-year, $33 million contract in 2018.

Police fly small drones with cameras to look at crime scenes, crashes, searches, and emergencies. In a drone-as-first-responder program, a drone launches to a 911 call and streams video before officers arrive. Chula Vista, California has run one since 2018 and got a federal waiver in 2020 to fly beyond the pilot's line of sight.
How long data is kept: Not confirmed; Texas and Florida limit when police may use drone images (see states).

Home cameras like Ring record porches and streets. In January 2024 Ring ended the tool that let police ask users for video in its app; police can still use a warrant, and Ring keeps the right to share video without consent in limited emergencies. A planned Ring and Flock Safety link (announced October 2025) was cancelled in February 2026; Ring says it never launched and no customer video went to Flock.
How long data is kept: Set by the homeowner's own camera plan; not a government record unless shared.

A device that acts like a cell tower so nearby phones connect to it, letting police find or identify a phone. It can briefly disrupt service for other phones nearby. Since 2015, U.S. Justice Department agencies must get a warrant first in most cases, and may not collect calls, texts, or data stored on the phone.
How long data is kept: Under the 2015 federal policy: delete data once the target phone is found (at least daily), or within 30 days when identifying an unknown phone. Local police rules vary.

Software that scans, sorts, and saves large numbers of public social media posts by keyword, place, or person. The Brennan Center found local governments spending millions on these tools, and that few had public rules for how they are used.

License plate readers: Ark. Code Ann. §§ 12-12-1801 to 12-12-1808 bans most uses except by police and a few others (parking, access control, some private property). Plate data may be kept up to 150 days (60 days for private landowners and businesses), longer only while tied to an investigation. Government may not sell, trade, or exchange the data; police may share evidence of a crime with other agencies, and others need a subpoena. Users must compile statistics every six months (plates scanned, matches, arrests) and keep them for 18 months for public review. Arkansas State Police rules limit use to 'legitimate law enforcement purposes', require a log of every disclosure, and send usage reports to the Arkansas Legislative Council quarterly. Body cameras: no statewide requirement to use them was found; a 2025 bill proposed one (final status not confirmed). Local context: in 2026 several Arkansas cities, including Searcy, paused or ended Flock contracts, and Fort Smith cut retention to 7 days.

A local law, based on an ACLU model, that lets the city council or county board decide if and how police use surveillance tools, with public input. The ACLU counts 26 places that have adopted one.
Example: Santa Clara County, California (2016), described by the county as the first of its kind in the nation.
Source: ACLU: Community Control Over Police Surveillance · ACLU of Northern California: Santa Clara County passes surveillance law (2016)
Before a department buys or keeps using a surveillance tool, elected officials must approve a written policy that says its purpose, allowed and banned uses, what data is kept, for how long, and who it is shared with. Officials must weigh benefits against costs, including privacy.
Example: Santa Clara County, California Board of Supervisors (2016).

Each year, departments report in public how each tool was used and what controls are in place, and elected officials review the reports at a public meeting.
Example: A 2020 review found all 14 local surveillance laws it studied require annual reports; Santa Clara County, Oakland, Davis, and Seattle had completed them.

Police publish an impact and use policy for each surveillance tool, the public can comment, and an independent inspector general checks every year whether police follow it.
Example: New York City's POST Act (Local Law 65 of 2020); the inspector general's 2022 report found many NYPD policies used general, boilerplate language.

A public web page an agency can choose to turn on that shows how many plate cameras it has, how many searches were run and why, hot-list alerts, retention, and its policy. The numbers are self-reported by the agency; the Rhode Island ACLU says many portals leave out key data.
Example: Kent County Sheriff's Office and Grand Rapids Police, Michigan (year not confirmed).

An agency can keep plate data for fewer days and stop other agencies from searching it.
Example: Fort Smith, Arkansas Police (August 2026) cut plate retention from 30 days to 7 and stopped other agencies' access; Van Buren, Arkansas made similar changes.

A state law can bar sharing plate-reader data for certain purposes, and a state office can audit compliance.
Example: Illinois (2023 law) bars sharing plate-reader data to enforce immigration or abortion laws; the Secretary of State's 2025 audit led Flock to change its system.
Source: AP via KSAT (Aug 2025)
Agencies must publish how often they flew drones, where, why, how many cases the drones helped, what was recorded about people who were not the target, and what the drones cost.
Example: Texas (since 2013) requires state agencies, and county and city agencies in places over 150,000 people, to report every two years; Harris County Sheriff's Office posts its reports.

A policy that police must get a judge's warrant before using a tool, except in emergencies, plus rules to delete data and audits to check deletion.
Example: U.S. Department of Justice cell-site simulator policy (2015).

A court settlement can set use rules, like banning arrests based only on a face match, requiring training, and reviewing past cases.
