Well this thread has gone on and off topic way to much, I am surpised it is has not been locked yet. Thanks to everyone for there adivice and opinion, except for those of you who said (call the cops first!!!) since I already pointed that out in my original post is was not much of a help.
Porch light with motion sensor would be a good idea, so would a peep hole. Unfortunetly I have a rental house and it does not have neither. And due to the set up of the house she could not see the front door from the upstairs bedroom. No DV does not apply to this. Dogs would be a great option to but since its a rental it is not an option at this moment
