We are extremely satisfied with their work and look forward to having QEI to service our future needs.“

“I got an Ultra 4K HDTV and SONOS wireless sound system as a surprise for my husband. Frank and his team had it installed in record time and they worked like a well-oiled machine. I’ve been married more than 20 years and this is the best surprise I’ve ever given my husband – he said it was set up perfectly.”
“I was given such good advice on what to purchase for my condo, how to place it, and the install was so well done. All QEI Security & Technology staff were professional, friendly, helpful, and the system is perfect for me!”
“I have personally and professionally been a customer of QEI Security & Technology for over three years with burglary alarm services at my home and office on Wall St. in Mt. Pleasant, S.C. The customer service has been excellent and consistent.”
“I used QEI Security & Technology to upgrade our home security and sound system. We like that the system is expandable should we decide to add other features in the future. The technicians were able to sufficiently explain to a non-techie what we were getting and how to properly use the system.”
