Burglars will tend to strike where they think the deterrent is low and their return is high. Below are some tips that will serve as good deterrents, giving your home a "secure look".
Keep shrubs and bushes trimmed to minimize hiding places that could provide a point of entry.
At night keep a porch light burning and utilize motion activated lights at the back and or sides of house.
All doors leading to the inside should be solidly constructed and have dead-bolt locks.
Keep doors locked - even when you are home.
Do not leave a note on the door that could inform a burglar that you are not home.
Windows should have secure locks and if left open for ventilation, should not exceed 5 inches - secured in place with security pins.
Do no hide a key in an obvious place that can easily be found.
If you have a garage, keep the door closed. Keep any ladders locked up so that they cannot be used by a burglar.
Make sure house numbers are readable from the street - including an alley.
Use a wide angle viewer (peephole) to check person's identity at your door.
When going out at night, connect one or more lights to a timer to create a "lived in" look. Also, a radio left playing can give the indication of someone being home.
Get to know your neighbors - watch out for each other. Consider starting a block watch.
If you see a suspicious person or situation call the police.
Engrave your driver's license number (not social security number) on your valuable items. Take photos of smaller items such as jewelry and silverware. Store photos and records in a secure place such as safety deposit box.
A dog and or an alarm system (with yard sign) have proven to be a good deterrent.
Make sure your efforts do not prevent a quick exit in case of a fire.
