Here's some suggestions. Burglers generally don't linger, they want to get in and out as quickly as possible so they will grab whatever is convenient. The object is to make it as difficult as possible to get in, and once in, as difficult as possible to get stuff that is worthwhile
*Install a home security system
*Install motion sensor lights in the front and the back of the house
*Disable your garage door opener
*Burglers will kick in your doors to gain access so have strong dead bolts installed
*You can also strengthen your entry doors by installing a product called Easy Armor Door Reinforcement Kit
*Make sure all your windows either have locks on them or a dowl in the sill to prevent them from being easily opened
*Install locking security screen doors on all your entry doors
*Most people will put small safes in a closet, install a dead bolt on the closet door
*If you have valuables, either store them off the premises or store them in the same room as the safe
*Put lights on timers, be sure and do more than one room
*Put a radio on a timer
*Be sure your curtains are drawn and/or shades are pulled so visability inside your house is limited
*If you do get broken into, be sure you have someone local you can call to come out and fix the damage pronto - broken windows or broken doors
*Let the local police department know you are gone
*Let your neighbors know you are gone
*If you have neighbors with an overflow of cars, ask them to park them in your driveway
*Have a gardener keep up your lawns and flower beds
*If you are leaving a place that snows, make arrangements to have your driveway and walkways shoveled
*In friendly casual conversations, do not tell people you are snowbirds
