# F4 Installs and Site Nomenclature
Several 2024–2025 threads document the naming, site selection, GPS placement, and camera-count growth of ASP's fixed **F4** ELSAG camera network. They extend the six-site picture from the [[Leonardo Pick Lists and ASP Deployment Sites|2026-06-05 fiscal production]]: the F4 project grew from 25 to **39 cameras**, and the site map reaches at least Site 9 across five Interstate corridors.
## What's inside
### `RE_ ARKANSAS STATE POLICE - FIXED LPR Project - Budget (2).msg` (2025-01-20 → 01-23) — 25 → 39 cameras
[[Craig Duncan]] flags a scope increase after the updated F4 site survey:
> *"we have a discrepancy in the number of cameras and what you have ordered… This now has 39 F4 cameras vs. the original at 25 cameras or 14 more F4 cameras than originally detailed. Therefore, the base cost on your F4 project shot up to $448,110 vs. the original $369,915. That's all while the Street Sentry program remains the same at $73,324."* (Tier-1 corpus, `RE_ ARKANSAS STATE POLICE - FIXED LPR Project - Budget (2).msg`). Overton: *"Good to go…"*
### `ASP - F4 INSTALLS - Nomenclature.msg` (2025-07-10) — GPS site list for the HIDTA EOC
Duncan asks Overton how the next install round should be *"called on the HIDTA EOC,"* listing sites, install dates, and coordinates (Tier-1 corpus, `ASP - F4 INSTALLS - Nomenclature.msg`):
| Site | Area | Coordinates | Note |
|---|---|---|---|
| Site 3 | North Little Rock | 34.784468, -92.134198 | Replace 2 LPR cameras |
| Site 6 SB | Big Rock Township | 34.610348, -92.268670 | Finish site 6 southbound |
| Site 4 WB | Little Rock | 34.652665, -92.413379 | New install |
| Site 9 SB | Hill Township | 34.855102, -92.136988 | New install |
| Site 7 NB | Marion | 35.247361, -90.219780 | New install |
### `RE_ Names for Sites.msg` (2025-07-14) — the EOC naming scheme
Overton supplies the naming convention keyed to corridor and direction (Tier-1 corpus, `RE_ Names for Sites.msg`):
- **Site 3** — *"Galloway (North Little Rock I-40)"* → `AR ASP / N Little Rock / Galloway / I-40 EB` (or WB)
- **Site 6** — *"near the Wrightsville exit on I-530 (South Little Rock)"* → `AR ASP / S Little Rock – Pine Bluff / I-530 NB` (or SB)
- **Site 4** — *"LR at Otter Creek on I-30"* → `AR ASP / SW Little Rock @ Bass Pro / I-30 EB` (or WB)
- **Site 9** — *"Jacksonville area on I-57 / US 67"* → `AR ASP / NLR / Jacksonville / I-57 / US 67 NB` (or SB)
- **Site 7** — *"North Bound only on I-55 in Marion"* → `AR ASP / West Memphis / Marion / I-55 NB`
Duncan confirms: *"I'm going to allow the field techs to install the cameras and then I will come back and adjust the names once they are live."* (Tier-1 corpus, same file).
### ARDOT MOU/GIS point register
The later ARDOT L000259 traffic-control-device export independently supplies nineteen exact points explicitly labeled `F4 ALPR Project`, `AR ALPR Project`, or `Street Sentry ALPR`, with ASP/AHP and MOU text. Its rows have no carriageway-direction field, so the wiki does not infer EB/WB or NB/SB merely from point geometry ([[Statewide Traffic Control Devices Export]], cited CSV lines).

The five install-email coordinates and the GIS points are separately preserved. Near matches at Marion, Jacksonville, Little Rock, North Little Rock/Galloway, and Landmark/Wrightsville are not averaged or silently substituted; the install email records a scheduled field point, while the CSV records an ARDOT GIS point.
### `ASP SITE SURVEY F4 - UPDATED.msg` (2025-01-23) and `Re_ ALPR Names for first four sites` / `Re_ Thoughts on this` (2024-12)
Overton signs off the updated F4 survey — *"This is perfect and ready to proceed…"* (Tier-1 corpus, `RE_ ASP SITE SURVEY F4 - UPDATED.msg`) — and, in December 2024, circulates *"names for the first four sites installed"* (attachment `ALPR Names for Site Locations.docx`) to ICP staff and Leonardo's Rob Ryan for sign-off (Tier-1 corpus, `Re_ Thoughts on this.msg`, `Re_ ALPR Names for first four sites.msg`).
## Key takeaways
- **The F4 fixed network grew to 39 cameras (from 25), at a base cost of $448,110.** The 14-camera increase and the ~$78K cost jump are documented, with Street Sentry a separate $73,324 line (Tier-1 corpus, `RE_ ARKANSAS STATE POLICE - FIXED LPR Project - Budget (2).msg`). This materially exceeds the initial buy documented in the fiscal production.
- **Sites are named to the HIDTA EOC.** Camera names are set *"on the HIDTA EOC"* under an `AR ASP / <area> / <corridor> <direction>` convention (Tier-1 corpus, `ASP - F4 INSTALLS - Nomenclature.msg`, `RE_ Names for Sites.msg`) — confirming the deployment is administered inside the federal HIDTA EOC platform (see [[HIDTA LPR Network]]).
- **The corridor map spans central and eastern Arkansas Interstates.** Documented sites include I-40 (Galloway/NLR), I-30 (Otter Creek/SW LR), I-530 (Wrightsville), I-57/US-67 (Jacksonville), and I-55 (Marion/West Memphis), reaching Site 9 (Tier-1 corpus, `RE_ Names for Sites.msg`, `ASP - F4 INSTALLS - Nomenclature.msg`). These are fixed cameras on public ARDOT right-of-way.

## Open questions / follow-ups
1. **Total final camera count.** The record shows 39 F4 plus a Street Sentry program; the complete as-built count across both modalities (and site numbering beyond 9) is not fully enumerated in the extracted text.
2. **The `ALPR Names for Site Locations.docx` gap.** The email body references this authoritative first-four-sites naming table, but bounded extraction of the MSG files and attachment folders did not recover the DOCX. The names above are therefore complete only for the five sites enumerated in the July 2025 body text.
3. **Complete site/direction crosswalk.** The nineteen ARDOT points expand the exact map but do not provide camera-level direction, site number, as-built status, or a complete 39-F4-plus-Street-Sentry inventory. See [[Arkansas ALPR Camera Coordinates and Directional Nomenclature]].
