Keeping doors & windows locked is 1st line of defense. Make wireless alarms your 2nd. The alarms are activated by doors or windows opening. Burglars hate noises, so even a small alarm usually sends them running. The alarms are available at home centers ($20-door alarms; $7-window). Or check out Intermatic at intermatic.com or Door & Window Alarms at doorandwindowalams.com. Use alarms for doors & windows in “hidden” areas of the house where you don't normally gather and that are often dark.
