We Handle The Tech, So You Can Handle The Business
Structured Cabling & Fiber Optic Systems
Cat6/Cat6A copper and OS2/OM4 fiber, terminated and tested to ANSI/TIA-568 standards. Every cable is labeled, documented, and tested.
Electronic Security & Surveillance
IP video, access control, and notification systems that integrate with your network. Designed so you can actually find the information you need and manage credentials without a vendor call.
Managed IT Services
Monitoring, support, and infrastructure management that keeps systems at peak performance and reduces risk, billed predictably and scaled to your size.
Telecommunication Room & Space Build-Outs
Clean, organized, properly grounded MDF/IDF spaces built for airflow, capacity, and the tech you'll add in five years, not just today.
RF & Wireless Systems
Site-surveyed wireless and RF coverage engineered for density and dead-zone-free performance across your whole facility.
National Rollout / Multi-Site Deployment
One contractor, but you’ll see consistent results at every location. We've deployed for national brands across 49 states and are on-site for each rollout.
Project Design
RCDD-level design built around your floor plan, capacity needs, and budget, so the spec is right before anyone installs a single cable.
Project Management
A single point of contact who owns the schedule and the trades. Clear communication, no finger-pointing, no surprises on the invoice.
We Can Help.
How do I know when to select a cable, go wireless, or use fiber?
Can we trust our cameras to catch what actually happens?
How much is all this downtime really costing us?
What's causing the Wi-Fi dead spots in our building?
Can we get the same setup at every one of our locations?
Can we plan our new space so we're not paying to redo it later?
We've heard all of it. After 35 years and 49 states, there isn't a cabling or infrastructure problem we haven't solved. We spec it right, document everything, and stay accountable after the invoice.
Working With Our Team Is Always Easy
Site Survey & Scope
We come to you, walk the space, and document exactly what needs to happen across cabling, security, access control, cameras, network hardware, and managed IT.
Proposal & Timeline
You get a clear written scope, fixed pricing, and a timeline you can plan around. We won't sell you something you don't need, and we won't say "no" because the job is small.
Install, Test & Support
We install to standard, certify and label every component, hand over the documentation, and stay on as your point of contact for whatever comes next.

Most companies hire three different vendors to cover all of that. With CIS, you get one partner. CIS has served businesses from Springfield since 1988.
