Most burglaries take place at night so be sure to install adequate outside lighting and replace burnt-out bulbs.
Do not leave house keys under doormats or in flower pots. Provide a key for each member of the household.
If you have an Intrusion Detection System at your home, arm the device whenever leaving the house or when going to bed.
Uncollected mail and newspaper is a telltale sign that you are not at home. If on vacation, have your mail and newspapers collected by a friend or neighbour so would-be burglars won't know that you're away.
Install smoke detectors on ceilings or walls within 15 feet of each sleeping area and at least one on each floor of the house. A fire extinguisher is a must in your kitchen.
If you see any suspicious person(s) on the outside of your home, or you are awakened by any strange noises, alert the police or, if you have a panic alarm system, deploy it immediately.
