About Us

 

FOSS and AVI are two experienced and established companies co-owned to be the Sioux Empires full-service integrators for all of your communications, security, entertainment & lifestyle needs.

FOSS started in Sioux Falls in 1999 providing primarily voice/data cabling services for the commercial market.  In 2000-2002 it expanded its offerings to add security services, small telephone systems, and central vacuum systems.  FOSS now provides a full line of services for the Commercial, Residential, and Agricultural markets.

Audio Video Integrations, LLC was formed in 2002 to provide Audio Video system design and installation to a booming residential market.  AVI now provides a complete line of services for the Residential, Commercial, and Houses of Worship markets.

We are unique in that FOSS & AVI both specialize in their respective fields, but work together with a combined office and Custom Design Center to provide you a central point of contact with a full menu of services.  We are able to provide our clients the specialized expertise they expect while eliminating the hassle and confusion of using multiple contractors.

“We just love our home theater! All the components match up to give us an awesome total package. The guys at Foss-AVI treated us very well and I have recommended them several times to friends.” - Bob & Mary

“We had another security company and they left the area.  Foss did an excellent job moving the equipment, setting everything up and provided the necessary follow-up.  Foss always has responded to any problems or questions in a quick and polite way.” - Gene

“I just wanted to let you know what an outstanding job you and the entire team have done.  We are very happy with the audio and video at this point.  We’ve had a couple of groups over and they all compliment us on the system and ask who installed it. Feel free to use me as a reference.” - James & Wendy

 “Foss provides great customer service as they are always available to help with any issues that arise. There have been only a couple minor problems with our system in the 6 years we have been using them but each time their technician has been able to correct the issue quickly. Very pleased with Foss Security and recommend them to everyone.” - Brian
