At FOSS and AVI, we work hard to provide the most state-of-the-art residential security and technology systems on the market today, but also know these systems need to be user-friendly and fit the lifestyle of our clients. This means taking the time to explain our systems, listening to our client’s needs, and then giving advice about the products that fit best. There is no one product or system that fits all in the technology world, but FOSS and AVI will help you figure out the best solution for your family. 

Services we offer include the following:


  • Home automation systems - Simplify and integrate all of your homes technology into a simple user interface (Audio, Video, Lighting, HVAC, etc.). 
  • Home theater - Whether it is a dedicated home cinema or theater/family room, enjoying a movie has never been this awesome! 
  • Movie/music management - A great way to bring your movie or music collection into an easy to use interface for the whole family to enjoy. 
  • Whole home audio/video systems - Whether you want a simple distributed music system or an advanced whole home audio/video solution, these systems clean up and change the way people use technology in their homes.
  • Lighting control - Provide energy savings, reduced clutter of light switches, easy scene operation, or even additional security while you are home or away. 


  • Security systems - Not only provide protection for your family, but can also do so much more! 
  • Camera systems - A great way to keep an eye on the kids or your property from wherever you are in the country. 
  • Cable infrastructure - This might be the most important thing you do in your new home. Homes in our area are completely sheet rocked, so a properly designed and installed infrastructure is key. 
  • Telephone intercom systems - A great way to communicate to your family around the house or maybe to your front door or gate 
  • Central vacuums - Are amazing and probably the most overlooked product today. We have a ton of cool products, but these systems might be the best!
