Three Flock Networks, Two Audits

A driver in Blount County can pass through at least three law-enforcement Flock Safety networks: the Maryville Police Department’s, the Alcoa Police Department’s, and the Blount County Sheriff’s Office’s. Each agency pays Flock for a subscription. Flock owns the cameras, hosts the resulting vehicle records, and provides the search tools that agencies across the country use to query them.

Every time an agency account runs a Flock search, the search can include its own network and every network shared with it. Flock records that search in a network audit for each agency whose network was included. This page compares the July 2026 network audits for Maryville and Alcoa to answer a direct question: who is searching the camera networks that watch Blount County roads?

55 Identified Flock Camera Records

The searches analyzed on this page are possible because Flock camera networks collect and store vehicle observations from roads throughout the area. MaryvillePrivacy.org’s current inventory contains 55 active camera records: 52 classified to local government networks and three identified as private/commercial cameras.

Where the Cameras Are

The 55 identified records extend across Maryville, Alcoa and surrounding Blount County roads. The map below shows Maryville Police, Alcoa Police, the current working classification of Blount County Sheriff’s Office records, and three private/commercial Lowe’s cameras.

From the Dataset to the Roadside

Camera-location records can also be compared with cameras documented in the field. The camera photographed below at Hunters Crossing in Alcoa corresponds to Alcoa Police Department camera #12, Hunters Crossing @ T Mobile in the current inventory.

Camera Deployment Reports

The reports below provide a closer look at each identified network. Each includes a deployment map, camera inventory, Flock IDs, device types, listed camera features, operational status and coordinates from the December 2025 source dataset.

Deployment reports are based on the December 2025 camera-location dataset. The reports are provided as static PDF records so the mapped locations, identifiers and coordinates can be reviewed independently of this page.

Detailed Camera Inventory

Select a network below to review the individual source records. Each entry includes the camera number, documented location or direction, Flock ID, device type, service status, coordinates, record-created date and the date the source record was last updated.

Important: “Record created” refers to the creation date contained in the source dataset. It should not be interpreted as the physical installation date of the camera.

One Search, Many Networks

A Flock search is not limited to one city. An officer’s account can search its own agency’s cameras and every network shared with that agency in a single query. When that query includes Maryville’s network, it appears in Maryville’s audit. When it includes Alcoa’s, it appears in Alcoa’s. When it includes both, the same search appears in both audits under the same search identifier.

Maryville and Alcoa in the Same Month

Both audits cover July 1 through July 31, 2026. Both were analyzed offline with the same tools, with times converted from UTC to Eastern time and each search counted once.

How Widely Searches Were Cast

Network breadth compared across the two audits: how many agency networks each search included at the time it was run.

Searches every day of July. Weekdays averaged about 70,700 searches; weekend days about 37,200.

Searches grouped by the home state of the agency account, with federal accounts treated separately.

How Often a Single Search Reached Both Networks

Searches were matched across the two audits by the search identifier recorded in each file. A search ID present in both audits is one search that included both Maryville’s and Alcoa’s cameras in the same query.

July 2026 search IDs found in both audits, in Maryville’s audit only, and in Alcoa’s audit only.

In July 2026, 1,284,759 searches included both city networks. That is more than nine of every ten searches that reached Maryville’s network, and about two of every three that reached Alcoa’s.

What Maryville’s Own Users Searched

The network audits above show who searched into Blount County’s city networks. Maryville’s Flock access log shows the reverse: searches run by Maryville’s own users, across whatever networks their accounts could reach. The log contains 20,197 recorded searches by 60 users between January 2, 2024 and October 27, 2025.

Monthly search volume. January 2025 was the highest-volume month with 2,150 recorded searches.

The 10 most active users accounted for 67.4% of recorded searches; the top 20 accounted for 85.8%.

Of 20,197 recorded searches, 15,552 (77.0%) contained a one-word reason, and 67 (0.3%) contained a reason of at least 25 characters.

What Two Audits Cannot Show

Records still worth requesting:

• The Blount County Sheriff’s Office network audit for July 2026, so all three law-enforcement networks can be compared for the same month
• Maryville and Alcoa network audits for months other than July 2026
• Each agency’s current sharing configuration, in both directions
• Each agency’s own current camera list, to confirm the 55-record inventory
• Access logs of searches run by Alcoa PD and Sheriff’s Office users
• Maryville access-log entries after October 2025
• Future audit exports in native CSV format

Camera inventory: compiled by MaryvillePrivacy.org from publicly accessible camera-location records correlated with identified agency and operator records. Full inventory with source identifiers and coordinates.

Method: Both audits were analyzed offline using open source tools including DuckDB and Python. Times were converted from UTC to Eastern time. Search totals are counts of unique search IDs in each audit; searches were matched across audits by search ID and are not multiplied by the number of networks each search included. Agency categories and home states were assigned from account names and may contain classification errors.
