Cornerstone Security is already working awesome for me and my husband. But it even made us love it more when one of their customer service representative called me just to check on us and the products that we had installed. She asked me if there's anything else that we would like to do or change in the settings or how the cameras were installed and if there's anything else that we would like to follow up regarding our security system. We were both really surprised because this is the first time that we have experienced this. The company is the one who calls to check on you if the products works to our satisfaction. Just WOW!
