Continued problems with the reliability of the system since initial install. After numerous calls I finally got someone to help. A repeater was recommended and sent at no charge. A technician responded and repaired a camera that had not worked since the first week of installation and which I had continued to pay for.in the week or so since the assistance of the technician everything seems to be working fine but I will reserve comment and wait to see how things are working a few months from now. I must also say that the technician was OUTSTANDING. He was knowledgeable and friendly and was not in a hurry unlike some folks I spoke with over the past few months at customer service. If this review was based solely on the help received from the tech it would have been five stars across the board.
