In 83 seconds, Eric Brackett explains how BTI designs access control around your doors, people and schedules, and supports it from Downers Grove, including Northlake.

Tired of access control headaches in your Chicago buildings? The right system makes employee changes fast and keeps sensitive areas under control at every site. I'm Eric Brackett, Founder and President of BTI Communications Group.
I founded BTI in 1985 installing business phones. Over 40 years later, your IT, cybersecurity, cameras, door access, phones and AI share one network, with one accountable partner for it all.
We start with your doors, people and schedules: who needs access, when, and which entrances, server rooms and loading docks need tighter control. When someone leaves, their access can be removed right away.
We are agnostic by design, supporting platforms like Brivo, Avigilon, Kantech and HID, and we can take over an existing system. Cloud access control is convenient but more limited to customize. An owned platform can be tailored and stays yours. BTI secures and can co-manage either.
After installation, you get 24/7 monitoring support and a one-day engineer response, with no call center, from our Downers Grove team, for changes, upgrades and expansion. BTI is ISO 27001 compliant.

★★★★★BTI Communications Group does a solid job. From the proposal process straight through to job completion and subsequent support, everyone does exactly what they say they will. We had a solution installed at one location as a test of sorts. Based on the success of that, we are now getting ready to install at a third location.

He continues to be responsive with providing the support that we need from initial setup to modifications of our current system in a timely manner. Dave has created a friendly and encouraging relationship which has been recognized by the Edgewood staff as well. His team has been an asset to Edgewood.
