         Building Relationships

                  One Project at a Time

Advent Systems  is a leading professional source of integrated solutions for your low voltage system needs.


We help you protect your people, property and assets with the design, installation and service of integrated electronic security systems.


Every project we do starts by getting a thorough understanding of our client's needs. Once we've determined the optimum solution, we develop, implement and integrate multiple systems into one structure, and we provide documentation and support so that operation and maintenance are painless.

We use products from leading manufacturers to ensure your systems run smoothly and can be expanded as your needs change and technology evolves.





Since our founding in 1994, we have been dedicated to providing our customers with the highest level of service and quality. We are also committed to unwavering integrity and building lasting partnerships with our customers, employees and vendors. We believe that our customers deserve the best, so we have created and live by this sacred promise — The Advent Advantage.


First, we strive to understand your technology challenges so we can develop customized long-term solutions that will serve you for years to come. Our proposals are honest and accurate and not change unless your needs do. Long after your systems are in place, we continue to be there for you, providing service and maintenance.


Your needs are unique. And you deserve an integrated solution that is customized explicitly for you. From our first meeting with you, we take the time to listen and truly understand your specific needs and requirements. With that explicit understanding we use our decades of experience to craft a personalized integrated system to best fulfill your objectives.


Our team members are among the most highly trained and experienced applications specialists in the industry. Ongoing training and certifications ensure we stay current on the latest technology trends which we apply directly to the custom-tailored solutions for our clients at major corporations, educational institutions and non-profits throughout North America.


We guarantee impeccable workmanship on every system we plan and install. Our employees' dedication shows in every detail, right down to your system's neatly dressed wires. Naturally, a quality system begins with the best hardware in the industry. That's why we utilize only the finest products from  leading manufacturers within the integrated electronics industry.


Service is the foundation of the Advent Advantage. Our dedication to your goals and systems extends well beyond the implementation phase. We will train your staff in all aspects of the integrated systems ensuring they have an in-depth knowledge of the technical architecture. And we offer ongoing service and support as needed.


I had the opportunity to work with Advent Systems many years back on a 3 floor Tenant Improvement project and it was apparent from the moment we began to work together that they were 100% committed to the success of the Project as being part of the solution.  From that moment on, I knew our partnership would grow and I could trust Advent Systems with any challenge presented.  Fast forward and I knew Advent Systems would help our Team in the incredibly challenging relocation of McD HQ to the West Loop.  Like our first project together, they were 100% committed to the success, helping shepherd the Project Team through the aggressive project schedule and coordination.  Their commitment to our Partnership, transparency, honesty and teamwork makes what we do possible.  Thank you!
