About Us

Our owner James Rienzo began in the low volt electronics field in 2004 and has earned many honors, especially in the automotive electronics field where he spent his first eight years. James received the USA Top 100 Installer award twice in back-to-back years, 2010 and 2011. After selling his company Installations Unlimited in 2012, James started on his journey of transitioning to the Home/Commercial Electronics field. After seven years of experience as a technician and operations manager, James opened On-Site Security LLC and recruited technicians he had met along his travels which also aligned with his and the company’s core values. Today we are a growing company enjoying the ride and looking forward to adding to our family of customers.
