"I would not hesitate to recommend MSI to anyone needing to have security cameras or alarms installed in their home. They always arrived at the time that was specified which was 0830. On their first attempt to install the cameras it was raining profusely but they tried to install them anyway. However, at one point it became to dangerous and they had to stop and reschedule the installment. Nigel Frazier and his team are very professional and knowledgeable about the security system that they install. I'm very pleased with their professionalism and reliability."

"Juan arrived a bit later than expected but got to work and did the jobs, running to Home Depot for needed parts which I didn't know we needed. He explaned things to me and knew what he was doing. He did all the jobs I outlined and left with everything working. He was cooperative in pointing the kitchen track lights where I wanted the to shine. He then looked at the plumbing job (vanity install) and realized that the vanity I bought wasn't a feasible option because of the direction of my pipes (to the side and not the back) therefore needing to go right through the drawers! I have returned the vanity to Home Depot! He didn''t waste time talking to me but did talk to himself (or on his phone ) while he worked! He cleaned up his dust and debris well, Satisfied with his cost which really should have been higher when I thought about it later. I would use him again if he was from near Frederick, but he came from Baltimore! I'd rather use local tradesmen...."
