Even though you stop the mail ask a neighbor or relative to check and be sure no one has stuck anything in your door, such as an Avon Book, or a notice that a package has been attempted delivery. This tells a crook that no one has been in or out of the door in several days.
Set timers on not only lights but also on a radio or tv so there is noise in the house.
Shut off the ringers on landline phones so someone outside cannot hear it ringing in an empty house.
Disconnect tvs, pcs, dvd players, dvrs etc to avoid power surges or lightening strike damage.
