Why QEI? Because Confidence is Everything.

QEI Security & Technology is one of the largest South Carolina-based security and home automation companies. We combine the latest technology with superior service to provide home security systems, small business security systems, 24/7 security monitoring, automation and smart home technology.

QEI Security & Technology has offices in five South Carolina areas: Charleston, Columbia, Bluffton, Greenville and Myrtle Beach. We also work hand-in-hand with many residential builders as the preferred security provider for their communities.

You can be confident knowing our 24/7 security monitoring is handled by a top-ranked TMA 5 Diamond Central Station (one of less than 200 in the nation).


Confidence is working with a company in your community.

QEI Security & Technology is headquartered in Charleston, South Carolina and we have offices in four other South Carolina regions.

We are not a franchise, we are not a dealer, we are not focused on customers in another state.

READ: Advantages of a Local Security Company

We were founded right here in Charleston and we are a family company with the third generation at the helm. Your account will always be serviced by a QEI Security & Technology employee in your community. When you call our office, you are talking with a QEI employee in South Carolina. Your technicians live right down the street from you. When you see us at the grocery store or a little league game, please say hi!

You can feel good supporting a local business and knowing that your investment will stay right in your community. But, we’re large enough to offer the same discounts and deals as our regional and national competitors. A basic security system, plus installation and activation are ALWAYS free. It is truly the best of both worlds!


Confidence is control at your fingertips.

We want you to use your system to save time and money from the minute your system is installed. That’s why we walk you through a full set-up of your control panel and free smartphone app. Together, we’ll customize the system to your lifestyle and make sure you know how to make changes yourself.

Our home automation systems include security, lighting control, climate control, garage door control and more. They are also equipped with geographic location technology – so your system can react based on the location of your smartphone! You can use “scenes” to automate multiple devices with the touch of one button.

Contact us to learn more about our home automation systems and security systems!


Confidence is an experienced installation team.

All QEI Security & Technology staff members are full-time employees – we do not use contractors. Our technicians are all and QOLSYS certified, and have attended hours of training on the systems they are installing and servicing.

The technician who installs your system is often the person you will talk to if you have any future issues. Their passion is electronics and helping you to realize the full potential of your system – whether you’re just remotely arming and disarming your home security system or controlling all the devices in your home.

Mike was awesome. He was very professional and answered all my questions. He was thorough and patient with me. It is a lot to learn and I am sure I will have more questions down the road. I feel safer in my home now and will certainly recommend QEI Security to anyone looking for a home security system. And I highly recommend Mike!
