Just know that if you have one of these systems installed there will be no support. Our system is under warranty for three years but if I call the installer there is only a 30 day warranty so they are going to charge me $150 an hour to come and troubleshoot the product. When I call the manufacturer they tell me that there is nothing they can do about that. They cannot help me with the crappy product that was installed and is not working at all 60 days after install. NICE.
