After Jim and Sue's break in and the robberies that occurred on the neighboring blocks we decided that we needed some type of surveillance security. We thought that the alarms were a good idea, but we go to thinking the we would like to know who is approaching the house, and for that we needed cameras. We went online to get an idea of what is out there, only to find out that there is a lot out there. We surfed from page to page, from manufacturer to manufacturer, and got more confused as we went along. There seemed to be no end to the choices, as well as the costs. You could have one simple camera or you could have multiple cameras with remote viewing no matter where you are in the world, and everything in between. Amazing! And the prices weren't too bad on any of it. Electronic prices are about the only thing that keeps going down. Which is a good deal for us. Usually when we go looking for anything it is priced out of range and heading up in price, not down. Instead of just lookin online we went to several places close by to see some of these units. The retail stores didn't carry a huge amount of inventory though.
