No two buildings, budgets, or use cases are the same. We walk every space before we design anything — because the right system depends on what you're actually protecting, who's using it, and how the building is built.
We've never installed the exact same system twice. We don't plan to start.
WHO WE WORK WITH
COMMERCIAL. INSTITUTIONAL. FAITH-BASED. RESIDENTIAL.
Commercial
Office buildings, retail spaces, and new construction across the region.
Institutional
Schools, government buildings, and public facilities.
Faith-Based
Churches and ministry organizations who need reliable, maintainable systems.
Residential
Custom homes where the technology needs to disappear into the walls.
THE DETAILS
WHAT WE INSTALL, WHERE WE GO, AND HOW A JOB WORKS.
If you're comparing contractors, here's what you actually want to know.
What We Install
Security camera systems — IP cameras, recorders, and remote viewing set up so you can pull footage without calling us. Commercial WiFi that covers the whole building, including the shop, the warehouse, and the lot.
Structured cabling — Cat6, fiber, patch panels, and clean racks that the next tech can actually work on. Access control for doors, gates, and fuel sites. AV systems for conference rooms, restaurants, and sanctuaries. And home technology that disappears into the walls.
We install equipment we’d put in our own building — UniFi, NETGEAR, Shure, Sonos, BirdDog — and we’re not locked into any of it. If a different product fits your job better, that’s what we quote.
Where We Go
We’re based in Rapid City and work across the Black Hills — Rapid City, Box Elder, Sturgis, Spearfish, Custer, Hot Springs — and out into western South Dakota, Wyoming, and Nebraska.
We also travel for the right job. We’ve run point-to-point wireless to a ranch outside Newell and installed fuel-site access control in North Dakota. If you’re not sure whether we cover your area, call us and ask. It’s a short conversation.
How a Job Works
You call or send the form. We come out and walk the building — how it’s constructed, where the infrastructure runs, what you’re actually trying to accomplish. Then we design the system, quote it straight, and install it ourselves. No subcontractors, no surprises on the invoice.
When it matters, everything runs on one platform. At Black River we put cameras, WiFi, and door access on a single controller — one place to add users, pull footage, or adjust schedules. See the work.
And we don’t disappear after the install. When something breaks at 4:45 on a Friday, you call the same people who pulled the wire — not a ticket queue in another time zone.
READY TO TALK ABOUT YOUR PROJECT?
We come out, look at the space, and tell you what it actually takes. No guessing. No generic quotes.
