Stop newspaper & mail delivery; or have your neighbor collect them for you.
Make your house looks lived in; have a neighbor put out & take in your trash cans, mow the lawn or clear snow off your cars & walkways.
Set lights on timers in multiple rooms. Set timers to go off and on at different times. Use exterior motion sensor lights in the front and rear of your home.
Lock all doors and window, including the garage door. Use high quality locks on your doors.
Tell a trusted neighbor when you’re leaving and returning, and ask them to watch your home. Give them a phone number where you can be reached, and a spare key for emergencies.
Alert your local law enforcement agency to watch your home while away
Consider a home security system. Burglars usually select unoccupied homes without alarm systems as their targets. Make sure your security system includes a loud inside alarm, detectors at all exterior doors, and motion sensors in the main living areas.
