Deb asked me why a wireless system would be better, and I had a bunch of reasons.  The first reason, of course, was that I was doing the installation. I wanted to have it bought and installed in a reasonable period of time.  I didn't want to fussing with wires and connections.  Plug and play is much easier.  We had spent a lot of time going over various systems, both the type we could install and the type where we had to have it installed.  I thought that for what we have in the house we were better off just going with a basic wireless unit.  It would be so much better than the wired sets too.  We wouldn't have to worry about what to do if the power goes out or if there is a short in the system.  I thought that wireless is the way to go.  Deb wasn't too sure though.  I ran her through some of the things that I learned, and I think she was convinced.  When we went over to Tom and Layla's house and found out that they had just installed a wireless system, I think that is what sold her on it.   The next day we placed and order.
