We were referred to Knight Security Systems by one of our neighbors, and we have had a great experience. They were quick to schedule an appointment with us, quick to get us a proposal, and quick to get the system installed. The installation took a few hours and was fairly priced. The monthly monitoring is also very fair and when we had an issue with our internet, they were able to send someone out right away to fix it. We highly recommend Knight Security Systems!

They have been excellent. I had some issues with the system the first week but Knight was quick to come out and address. The prices are fair and the technicians were clean and polite.

I am a painting contractor and have worked along side of Knights' installation team at a customer's home. They were organized, easy to work with, neat and personable. I have dealt with them for the past few years. They are professional, knowledgeable, honest and eager to accommodate your needs. Knight Security is direct, informative and will have your best interest in mind.

Highly recommend them, they are knowledgeable, trustworthy, and delivered everything that I expected.

Working with them has been an absolutely delight. They know what they are doing, explained everything to me in detail, and even were there to help when I encountered a problem. Very tech savvy too, which I can't say about my previous encounter. Thanks guys!

Knight is a great, local company that is always clean, polite, and responsive when they come out. I cannot recommend them enough.

Knight Security installed a security system at our business a few months ago and we have been so happy with it. When the technician came out, he walked through the entire location with us and showed us where everything was going and how it would work. We were also a bit worried about false alarms, so Knight Security worked with us to create a system that would be consistent. We were so pleased with Knight Security that we installed a security system in our home. They gave us 3-months free monitoring on our business as a Thank You. As a family owned business ourselves, we love working with another company that’s family owned and operated and handles each customer with care! Highly recommend them!!!

Not just your average security company. I invited Knight Security Systems to my home. They created a security system which not only protects my home from intruders, but a fire and carbon monoxide monitoring system that works great. I recently had an issue and after contacting Knight Security, they were incredibly responsive and handled my issue within moments of my call.

If you want a system that does what it supposed to do, with folks who care about what they're doing and make sure you understand what you're getting, then you call Knight Security sSystems. If you want a POS that may or may not work when an emergency occurs-there's Home Depot and Staples.

I had an ADT security system and was paying over $50 a month. When I was talking to my neighbor about how high my home security bill was each month, she told me that she only pays $30 a month and recommended I call Knight Security Systems. After looking over our paperwork, Knight Security Systems was able to transfer over our security contract and they told me they didn’t even need to switch out any old equipment. Now I pay $30 a month! It only took the install team (who were extremely courteous, even wearing those cloth things over there boots!) 15 minutes to re-program the machine and that 15 minutes is now saving me over $200 a year! I highly recommend Knight Security Systems.

Knight Security Systems has gone above and beyond to help us secure our business. They are fast to respond, courteous, knowledgeable, and extremely fair priced. We have recommended them many times in the past and will continue to do so for many years in the future. Thanks again for all your help!

I was referred to Knight Security by my doctor after a home in our neighborhood was broken into. My experience with Knight Security was extremely positive. They were courteous, informative, and extremely fast in getting back to me. The technicians were great as well. I have already recommended Knight Security to my other neighbors and will continue to do so. Thanks guys!!!
Incredibly quick to get back to us whenever we have an issue and extremely friendly technicians that are comfortable to have in our home. We had a few companies come out but Knight Security Systems were by far the most comprehensive and responsive company. They set us up with an app to arm the system from our phone and the total investment was within our allotted budget. Thanks again!

Knight Security recently installed a fire and security alarm system in my church. It was obvious to us that our Rep really knew his stuff and was very helpful. Every aspect of the job went smoothly, and we are extremely happy with the new system. We would highly recommend Knight Security to anyone.

Installation was handled with expert care. The system to date has lived up to our expectations. The team has been professional from top to bottom. Would highly recommend.

I Highly recommend Knight Security. They have outstanding customer service, the workers are careful during installation leaving everything clean at the end. Great experience.
