Comments: We were recently interviewing security companies to have surveillance cameras installed in our home. Representatives from Modern Security Integration (MSI) came to my home and their customer service was outstanding. They made us feel important and they provided valuable information about the cameras we needed. We knew immediately that MSI was the company that we were going to use. Once we signed the contract, the installation techs showed up and offered more advise before they actually did the install. In the end, we were very satisfied with the entire experience and I recommend MSI to anyone interested in added security in their homes



Review by Johnnie R. in Dayton, MD

Comments: This company is very high tech and energetic. The personnel are outstanding. They are constantly checking to make sure the cameras and electronic equipment is functioning the way you want them to. The extremely technical knowledge is high quality and very knowledgeable in the field of technology. I have already recommended this company to my neighbor and they are the highest quality that anyone could ask for. Although they are a five star company I would give them a ten! The price of the project was much more reasonable than other companies.
