Know this before you order the system. The "look" is pretty hideous. The control box looks like an enormous, white, 1980s answering machine. Do you really want this sitting by your primary door? The door triggers are also large and obtrusive and white. If you have dark door frames they will stick out like sore thumbs. I took it out of the box, realized I couldn't live with the aesthetics and immediately called to cancel. As I was inside of 7 days, this was allowed, however, I am being charged $80 for a "restocking" fee. (That's $80 for someone to take it back out of the box.) Yes, that was in the fine-print box that they ask you to stop and read during their pressure sales call, but that only makes it slightly less odious.
