Who we work with in Lake County, IL
Professional and corporate offices
North Shore and central Lake County offices in Highland Park, Lake Forest, Vernon Hills, Libertyville and Buffalo Grove need secure networks, Wi-Fi, phones, cameras and badge access for single and multi-tenant buildings.
Life sciences and healthcare neighbors
Lake County is publicly known for a large life sciences and healthcare employer base, including headquarters and major facilities along the North Shore and central corridor. This page does not claim any BTI work for named employers.
Manufacturing and distribution
Plants, warehouses and logistics sites in Waukegan, Gurnee and Mundelein need shop floor networks, dock cameras and access by shift.
Medical groups and clinics
Medical groups, dental, behavioral health and pharmacy practices that need secure systems, protected records rooms and patient friendly entries.
Schools and public agencies

Multi-tenant property managers
Portfolios that want one partner for common area access, cameras, cabling and tenant improvement work.
How working with BTI starts
- Free consultation. Tell us about your sites, systems and goals, by phone or at our Downers Grove office.
- Site visit or assessment. An engineer reviews your IT, security or phones in person or remotely.
- Written scope. You receive an itemized proposal and a plan you can share with leadership.
- Installation or onboarding. Our crews and engineers do the work on a schedule that fits your business.
- Ongoing support. Help desk, on site service and the 24/7 NOC/SOC keep things running.
Why one partner matters
Cameras, door controllers, phones and Wi-Fi all live on your network now. When different vendors own each piece, problems bounce between them and security gaps open where systems meet. BTI designs these systems together: cameras and doors on secured network segments, phones and Wi-Fi sized for the building and one team accountable when something breaks.
