Premier Security System Company in O’Fallon, MO, and Surrounding Areas

Dave was absolutely great to work with! We told him what we were looking for and he built us a package around our needs and budget. He explained everything in great detail, did an amazing job doing the installation, then went over the system so we understood how it all worked. Actually made the whole process very enjoyable. Reliant, LLC was definitely the way go! Couldn’t ask for a better experience!!

Very easy to work with! Did not try to oversell me anything. Was neatly installed beyond by expectations! Modifies it to your liking. Every inch of my property is recorded and monitored! Super friendly!
Takes time to answer all of you questions. You can’t go wrong with Reliant LLC!

Dave was referred to me by a friend who used him for her home security. I must say, he’s just as good for commercial work. My firm was just going to use him for cameras on our floor, but his professionalism, prices, and quality of work lead us to hire him for our locks as well. Highly recommend!

Needing to install cameras and a doorbell in addition to the existing house security we settled with Dave Steffen, owner installer of Reliant, LLC. We couldn’t be more pleased with the results. His product knowledge of security systems and installation mattered. He knows where to locate wired cameras for the best results with minimal impact and attention to detail of fit and function. He made sure we knew how to use and interact with our new equipment after the installation. He has a practical and friendly demeanor.

Dave was fantastic to work with. He advised us on the best system for our office, expanded the bid when another contractor fell through, and was responsive, timely, and great to work with. I would absolutely recommend Reliant.

System works great for us. Reliant seems approachable and answers the questions.
I feel he is able to teach you about your system instead of leaving you guessing

Dave and his crew are a pleasure to do business with. Great communication and delivery, very easy to recommend Reliant to others.

I came across Reliant Security at this year’s fall 2023 home show. I was frustrated with my previous security cameras and Dave suggested a different system and he scheduled an appointment for a home visit. He was very professional and pleasant to talk; he showed up as promised and did a thorough assessment; he explained his work and quoted me price. I did not feel pressured and he didn’t come across as a used car salesman which I greatly appreciated. When it was time for my install Dave arrived on time and got right to work, his attention to detail and the way he treated my home/property with the upmost respect did not go unnoticed. It was a very professional install and he cleaned up every area he touched. After the installation he asked me if I had and questions and set all my cameras up to my hub. Dave was very patient and didn’t rush out the door after the install. I would highly recommend Reliant Security to my family and friends without hesitation. I also appreciate that this is a family owned company.

Dave was very professional and helpful. The alarm system gives us peace of mind and is user friendly. Thank you Reliant!!

This project was top notch. Dave made recommendations as to the type of security camera that would best meet my needs, before my scheduled appointment . He arrived on time, made suggestions as to where my new camera’s should be installed for optimal view.. He set up my new Ring cameras to my phone. He completely went over any and all questions and concerned that I had. I would definitely recommend Dave with Reliant LLC to anyone looking for the very best security camera installation!

Dave came out reviewed our house and our expectations .He worked up a proposal including his recommendations and advice . Dave Returned on the 5th of July , completed the installation and spent as much time as we needed to go over the software and how to use the app on our phone . Couldn’t be happier or more pleased with the job that Dave at Reliant LLC did for us.

Great job all around. He was fast, helpful, knowledgeable. Highly recommend.

I highly recommend Dave with Reliant Security! The system was affordable and the process was very easy! We love the way our new system looks and we feel safe knowing we are protected with Reliant Security!

Dave Steffen, the owner, was great to work with. He responded quickly to my request and answered all my questions promptly. He showed up on time for our install and did an excellent job, he went above and beyond to keep his work area clean and to not disturb me while I worked from home. He set everything up and spent time showing me how to use the panel and the app, both are very simple to use. Highly recommend Reliant to anyone in need of security. Iâ ve never felt safer in my home.

Very satisfied with my decision on choosing Reliant security system for my business! Dave was very personal. He walked me through the system and was very knowledgeable about the cameras.

I was very impressed with the owner of Reliants knowledge when setting up our security system at Lake of the Ozarks. The attention to detail during installation and the information he shared with us about the equipment made me feel confident in our decision. The process was seamless and gave us exactly what we wanted to protect our second home.

Reliant was great to work with – we really enjoy the alarm system and cameras for added security. Very responsive, helpful and professional. Thank you Dave and Reliant!

We love our new security system from Reliant! Dave made the entire process quick and easy! The cameras provide a crystal clear picture and the app is so easy to navigate. I highly recommend you give Reliant a call if you are looking to feel safe and secure in your home!

Dave was so great to work with – knowledgeable, friendly, professional, and made absolute sure we were happy with the work. He installed cameras and garage door sensors for us and even had to pivot and find another option for the garage doors to make sure we got what we needed. I’d definitely recommend reaching out if you’re thinking about home security or even just have questions about the options available!

Fast, clean install. Educated me on my program throughout the entire installation. My doorbell cam covers my entire yard and driveway. Software is so user friendly. Couldn’t be happier to choose Reliant. Local, customer focused. You will not get better customer service. Call Dave!
