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.

Review by in Huntingtown, MD
I was extremely pleased with my experience working with MSI. I have had ADT in the past and have been unhappy with their customer service and rates. MSI sent out a very professional representative, Mr. Miller, who allowed me to create my own custom security system based on the needs of my home and family. The very next day I had an appointment to be installed and was again very happy with the service, timeliness, and professional demeanor. All of the information from both individuals was explained clearly, I have never experienced such wonderful service from a contractual company in the past.

I found the staff at MSI to be top notch. MSI installed both my home security system as well as my camera system. I was thoroughly impressed with their professionalism from the sales team and installers. The project was completed on time, below my initial budget, and overall exceeded my expectations. I would recommend this company they are great!!!!
