Engineering and Design Services

Success in systems integration cannot be achieved without a strong foundation in engineering. System design and engineering drives everything we do related to system sales, installation, service and maintenance. Matching products to applications requires engineering verification. Our installations each utilize our engineering services for internal construction prints when building systems, functionality verification, and “as-built” documentation, even if working with a system specification made by others.
In addition to technical logistics and installation assembly documentation, our engineering documentation serves to verify system completion. We archive all system documentation for quick reference in accommodating repair services and maintenance projects.
Our engineering department staffed by industry-certified designers, programmers, and technical specialists in areas of video conferencing, digital editing, signage and media file technology.
Product & System Sales

Since TEL Systems was established in 1965, we have built a reputation for high quality and also as an industry leader. This foundation in quality work, along with our relationships and affiliations we have established, have given us access to many technical, educational, and cooperative resources. These resources include a knowledgeable work force, access to the best products, examples of prominent and advanced system completions, affiliations with the best industry groups, and excellent client references in support of our work.
Our sales staff brings all of this together to offer solutions that will meet your AV and video needs. Our dedicated account managers guide every phase of the process, from analyzing your specific requirements, to the system’s completion and follow-up services.

Service and Maintenance
Once the system is installed, repair service, support and maintenance are critical in ensuring continued success in achieving the objectives. We have crafted a large part of our reputation on developing a responsive, reliable and well-trained service center. Our company was founded in 1965 for the purpose of providing repair and maintenance services for clients in Michigan and later developed the equipment sales and installation aspect of the business. Service and repair was an original focus of our company and remains an important part of what we do today.
Our fully-staffed service department, located at our Ann Arbor office, takes products in for repair at our facility, and we will also service systems and products at your location. Our technicians are manufacturer-trained, providing repair and also warranty services supported through those manufacturer service networks. Experience is critical when providing these services. Repairing products and systems correctly and expeditiously helps preserve your bottom line. Our technicians each have over ten years of experience providing these services in the commercial AV, video and sound industries. Most have worked for us for longer.
We offer per-project services in addition to maintenance and service agreements. We are happy to show you how we can assist with your service and maintenance needs.
