No one individual or agency working alone can prevent crime. It takes police and citizens working in partnership. The Naperville Police Department community policing strategy provides many ways for the police and communities to work together to prevent crime and build safer neighborhoods.
One of the most important things you can do is to know who belongs in your neighborhood and be alert in protecting not only your home, but your neighbors' as well. Report any suspicious persons immediately to 9-1-1.
Residential Burglary Prevention Tips
Doors and Windows
- Windows have latches not locks; therefore, install secondary locking devices on all windows.
- All exterior doors should be solid core or of metal construction.
- Exterior doors should have deadbolt locks with a 1-inch throw and reinforced strike plates with 2-3 inch screws. Most importantly, use them!
- A good quality double cylinder deadbolt lock should be used if there is glass with 40 inches of the lock.
- Install a peephole with at least a 180-degree viewing area.
- Secure sliding glass doors. A metal or wood rod along the bottom track is advised, as is the installation of vertical bolts along the top track.
- Secure basement windows with grilles or grates (but make sure they can be opened from the inside in case of fire).
Exterior, Interior, and Landscape
- Install outside lights and keep them on at night. Pay special attention to entrances, porches and yards.
- Use inexpensive timers or photo electric cells to automatically turn lights on and off and dusk and dawn.
- Create the illusion that someone is home by using timers on lights and/or leaving the TV on.
- Trim shurbbery and trees so doors and windows are visible from the street.
- Don't let your tree be a ladder. If there is a second floor, prune nearby trees so a thief cannot use them to reach second floor windows.
- Don't leave ladders or tools outside; they can assist a person in gaining entry.
- Draw all curtains/shades at night to prevent viewing from the street.
- Learn how to use your alarm system properly to reduce false alarms. Fees can be assessed for excessive false alarms.
- Put a warning sign on windows and entrances.
- Know your pass codes and make sure your call back list is up to date.
Additional Prevention Tips
- Keep doors, windows and garage doors locked even when at home. Patrol officers report hundreds of open garage doors each month during the evening hours.
- Never leave a house key in an obvious place such as in a mailbox or under plants or doormats.
- Don't tell a stranger that your neighbor is not home or volunteer any personal information about your neighbor.
- Do not post on any social networking sites that you are going out of town.
- While traveling, keep your home looking lived-in by having the grass cut, mail and newspapers picked up, and lights turned on and off with timers.
Burglary to Motor Vehicle Prevention Tips
- Don't leave vehicles unattended with the doors unlocked, windows down or the keys in them, even in your garage or driveway.
- Always take your car keys with you and lock your car doors.
- Take valuables with you or keep them out of sight by placing them in the trunk or using stow-and-go seating, preferably before arriving at your destination.
- Park in well-lit areas.
