Good idea about the video equipment. I'll see how that idea goes over.
We have talked about going to the door and its danger. My parents have always done it and they may not want me to do it, but they will not hesitate. It's really odd.
When you open the door, there is only about a foot beteen you and potential attacker. They can stab, shoot or grab you, and there's not much you can do at that point.
I also question why someone would approach my house unexpected and uninvited. They must know people are apprehensive. IMO, it's inconsiderate to do it, unless there is a dire emergency. Most people have a cell or can go to a store for emergency assistance.
