Curators of Cutting-Edge Technology Solutions

Our people and the services we provide define our firm. We take pride in delivering a first class client experience.

Who We Are

Comprised of installers, built by technicians, WOSV’s foundation is based on people who have been providing smart home services to clients for many years. Starting with the ownership, all of the owners began their career as smart home control system technicians. It is from this perspective that WOSV was born. At our core, we believe that the client and their understanding of the end result is what matters. We are dedicated to providing what is right for you as a client, not what someone else may think is the “latest and greatest”. It is our belief that job one is to tailor the system to the client and their lifestyle, complimenting your home life in Danville, CA, not complicating it.

Our Mission

There is one primary objective here at WOSV, provide the best possible client experience. We understand that home technology can be daunting, and maintaining “the latest” can result in many frustrating hours on tech support. Our goal is to take the frustration and turn it into enjoyment. Life has enough challenges, when it is time to relax with the family with solutions such as whole home audio, no one wants to be on the phone with support or online in a tech chat. We aim to use our years of in-home experience to simplify and enhance the interaction with your smart home. Making the smart home concept a reality for you and your family.
