Yeah very true.. I wouldn't go looking for it thats for sure.. But if they were coming at me then id do what ever i could do make sure my wife and I were safe. if they came into the bedroom to try and hurt you that is.

Just most important thing is to know they are there before they are standing over you least you can lock ya self away and call cops.

specially if your mrs is home alone. she just feels safer knowing alarm is on when im not home as well as every other night. if it hasnt gone off you know no body is in the house.
