I've compiled a list of tried and true home security measures to do before you step out, or pack the family in the car. Nine are basic practices, five are advanced measures to install ahead of time (now?) to make sure your house is not an easy target.
I very intensely wanted to learn how to prevent a home break-in. For inspiration, I turned to castles. Not just any castles mind you, but Norman-influenced castles built in England by William the Conqueror beginning in 1066. Why those?
