D & I Electronics

D & I ELECTRONICS Inc. has been in the Will county area for over 38 years providing security services for thousands of business and residence customers. We are the only company with our own central station located right here in the Joliet area and not in Texas, California, Florida, or some other distant location like the huge marketing companies. Our main focus is on installing and servicing burglar and fire alarms, but we also install camera systems, central vacs, music intercoms, and business telephone systems.
