The Alliance Security technician arrived within 10 minutes of the beginning of the window they promised he would be here. He was very professional in explaining the system and getting my approval before he started installing the system. John first covered the work surface with a cloth (so he wouldn't get my house dirty) and then proceeded to install the components. He cleaned up after he was done and showed me how to use the system. I was very pleased with this experience.
