Tech Systems

What Tech Systems does

Tech Systems is a privately held, family and veteran-owned security systems integrator founded in 1983 and headquartered at 155 North Greenleaf Street in Gurnee, Illinois. The company designs, installs, and services integrated security systems for residential and commercial customers across Northeast Illinois and Southeast Wisconsin, including Kenosha, Milwaukee, Genoa City, and North Chicago. Its core product portfolio spans four areas — access control, fire alarm systems, burglar alarm systems, and surveillance/camera systems — supplemented by add-on modules such as medical alert, apartment intercom, cellular elevator phone conversion, glass break sensors, motion detection, smoke/heat detection, keyfob controls, remote system login, and multifacility integration. The technology stack is built on third-party platforms and hardware from Honeywell, Alarm.com, Alarmnet, 2GIG, Nortek, and Linear Access Control, with remote monitoring delivered through TCP/IP-based control systems and cloud-based services.

The company makes money through three distinct revenue streams: one-time product sales and installation of security hardware, recurring monthly monitoring subscriptions for installed systems, and ongoing service and maintenance contracts. Pricing is quote-based and not publicly disclosed, with free next-day estimates and a one-year product warranty plus 90-day service warranty offered to customers. The go-to-market motion is sales-led and field-driven, relying on direct phone, text, and website callback requests, supplemented by local SEO and BBB accreditation. All employees are state-registered, and the business holds License #127-000462 and membership in the Northern Illinois Fire Inspectors Association. Tech Systems operates with 1–10 employees and no disclosed funding, M&A activity, or institutional investors.
