I have been using  Security one for many years .So I decided to have cameras put up so I decided to use Security One again. Randy  Sleiman the consultant was great .He explained  everything to me and where to put the cameras and how many I needed. Randy  even went out of his way for me . If I ever need anything else I would call Security One.
Thanks

Professional, knowledgeable, courteous, efficient, diligent, pleasant, are words that I would use to describe  Bassel Elturk, alarm system technician for Security One.
In the process of rendering my old alarm system properly operational and switching it over to Security One monitoring, he not only exhibited the above mentioned qualities, but also addressed my multitude of questions with genuine answers. It became readily obvious that this man truly enjoys his work, and quite frankly, that is the type of individual you want working for you.
Bassel, thank you for your superb work, and the manner in which you and
your associates, Andy and Duane, accomplished it.

I should mention that I was also very pleased with the work of Andy and Duane, and my reviews of them will appear on a separate request from Security One, as this request is strictly for Bassel.

I wanted to take steps to secure my home so I reached out to Security One for advice. I spoke to Mark Morris who was able to visit me that very afternoon! I told Mark what I thought I wanted and he told me what I actually needed based on his many years of experience. He was polite, very professional and thorough. He took the time to explain exactly what to expect. Mark made the whole experience easy and comfortable. I was grateful for his expertise and highly recommended him and the company.

When we reached out to Security One Randy was assigned to us as our salesperson. He was really good and patient at guiding us with the transition of our home alarm system. He always answered our calls, responded to all of our questions, and ensured we got all of the relevant new components added to our existing system. He was really great to deal with, and we can say he is a good ambassador for Security One! Thank you very much for your assistance and kindness Randy!
Our technician Bryan was awesome too. He worked diligently to ensure that all components of our alarm system were well connected and working properly. Thank you very much Bryan for your skill and professionalism and friendly conversations throughout the day!
We are also very glad that Security One is a local company and now we have the benefit of the local support, prompt response, and experienced technicians for all of our home security needs.
A wonderful, positive experience overall!!
I would highly recommend Security One to anyone looking for a new local company to manage and monitor your home alarm needs!
