Customer Testimonials



" I built a new house.  I prob. hired 50 sub contractors.  D I Security installed my security system.  They were one of the best sub contractor I hired.  Alex was extremely knowledgeable, an excellent installer, did a great job with tutorials, explained other options and upgrades and was very competitively priced....ahh, what more can you ask from a company?  I could not be more happy with my security system and my dealings with D I Security Group.  I highly recommended them for anyone who seeks to secure their property."
