What We Install

Low voltage work,
done right the first time.

Structured Cabling

Cat6 and Cat6A data runs, fiber terminations, patch panels, and rack organization — documented and labeled to last the building's lifetime.

Security Cameras

IP and analog camera systems with night vision, motion detection, remote viewing, and full NVR/DVR configuration for homes and businesses.

Wireless Predictive Planning

Predictive Wi-Fi surveys modeled on your floor plan — access point count, placement, and channel plan worked out before a single cable is pulled.

Network Infrastructure

Managed switches, wireless access points, and rack builds engineered for real-world performance — not plugged in and hoped for.

Troubleshooting

Dead drops, slow links, dropped Wi-Fi, and cameras that keep going offline — tested, traced, and fixed at the source, not worked around.

Access Control

Keycard readers, keypad entry, video intercoms, and electric strikes for offices, shops, and residential properties.

About NL Nexus

Built by someone who still picks up the phone.

"We treat every cable run like it'll be inspected — because eventually, it will be."

NL Nexus was founded on the belief that low voltage work deserves the same craft and attention as any other trade. Brian Kopp started in the field, running structured cabling, camera systems, and AV wiring in new construction and retrofits across Northeast Wisconsin, and still leads every job personally.

No subcontracting, no surprises. You get an honest quote, a clean installation, and a technician who knows every wire in the wall — because he put it there.

How It Works

Simple from first call to final walkthrough.

Site Walkthrough

Brian visits your location to understand the space, your goals, and any existing infrastructure. You'll talk directly to the person doing the work — not a call center.

Custom Proposal

You receive a written, itemized quote covering equipment, labor, and timeline. No hidden fees, no upsells you didn't ask for — just a clear picture of what the job costs.

Clean Installation

We work around your schedule, protect your space, and don't leave until everything is tested, labeled, and documented. You'll know exactly what's in the walls.
