Headquarters and regional offices in Oak Brook, Downers Grove, Naperville, Lisle and Itasca: IT, Wi-Fi, phones, cameras and badge access for single and multi-tenant buildings.
Accounting, insurance, legal, engineering and financial advisory firms that need secure remote work, client data protection and dependable phones.
Medical groups, dental, behavioral health and pharmacy practices that need secure systems, protected records rooms and patient friendly entries.
Plants and warehouses in Addison, Itasca, Wood Dale, Bensenville, Carol Stream and West Chicago that need shop floor networks, dock cameras and access by shift.

Portfolios that want one partner for common area access, cameras, cabling and tenant improvement work.
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.
Our Downers Grove engineers have installed cameras and Avigilon Alta (formerly Openpath) access control for clients in Downers Grove itself, a few minutes from the office.
Within about 5 miles of 1441 Branding Ave. Same day visits are routine.
About 5 to 10 miles west. Corporate offices, research and technology firms, medical groups and light industrial buildings along I-88.
