Great customer service from start to finish. The office manager and sales representative played a vital role in meeting my needs. Although I had higher expectations of the camera view based on my consultation, they have managed to satisfied my needs and ensured that I was pleased with the work. One of the installers was very helpful and extended service support for future concerns/questions.

Modern Systems did an excellent job on installing and upgrading my security system. The technicians were very professional and respectful of my homework. The salesman as extremely knowledgeable of the product and didn't pressure me in making any quick decisions. I would highly recommend Modern Systems Integration if you are looking for home or business security solution.

I owned 10 cameras and just hired this MSI for installation at $100/camera. The guy who conducted the estimate, said that I may need 10 cameras to cover the space I wanted, but that the technician would confirm for sure. Long story short, the technicians determined I needed on 8. Without even trying to use the wires that I owned, they used their own wiring, which normally comes with a fee. The technician offered to take some of my wiring as a swap, so that I would not have to pay the fee for his mistake. I agreed. The next day, the company tried charged me for the 10 cameras and the wiring.

Review by in North Bethesda, MD
I hired MSI to install a video door phone/intercom for my office. I bought the hardware over a year ago and MSI performed the install. Unfortunately, the system I bought (not from MSI) didn't work out of the box. The installer went out of his way to get things to work.

MSI installed our video surveillance system. There sales rep. was very helpful. Their price was $1,000 lower than competitors. MSI did an excellent job. The system is fantastic. The system allows viewing on a smart phone, lap-top and my work computer. I would absolutely, recommend this company to anyone considering a video surveillance system. They did exactly what they said they would do. They delivered a home security product that gives me a tremendous peace of mind.
