Frequently Asked Questions About Low Voltage Services in Chicago
What does a low voltage contractor do?
A low voltage contractor installs systems that run below 50 volts: security cameras, access control, intercoms, data and network cabling, WiFi, audio/video, and phone systems. Unlike a general electrician, low voltage is all we do — so terminations, testing, and code compliance for these systems are our specialty.
Do you serve both Chicago and the suburbs?
Yes. We work throughout the city of Chicago and all surrounding suburbs in Cook, DuPage, Will, Lake, and Kane counties. Visit our service areas page or call to confirm your location.
Are you licensed and insured?
Yes. Windy City Voltage is fully licensed and insured for commercial and residential low voltage work in Illinois. Certificates of insurance are available for your building management before work begins.
How much does low voltage installation cost?
It depends on the system and building. As reference points: most commercial camera systems fall between $2,500 and $15,000; cabling projects are typically priced per drop ($150–$350 depending on distance and construction); access control usually runs $1,500–$3,500 per door. Every project starts with a free on-site estimate and a fixed written quote.
Can you combine cameras, access control, and cabling in one project?
Yes — that's our most common project type, especially for new buildouts and office moves. Bundling systems into one install saves money on labor and ensures everything shares clean, documented infrastructure.
