Security With A UFO Home And Personal Alarm

My husband and I decided to go on a vacation that has been long over due.  He works extra hours and my job requires me to be on call a lot of the time.  While we were packing up the car we started thinking about the fact that we did not have an alarm system in the house.  Our neighbor came over and was talking to us when he mentioned that they went away and he bought a couple of UFO Home/Personal Alarm devices for his home.  He even took one along with them in the car for safety.  He told us where to find them and offered to show us where it would be best to install them.
