Plan to "burglarize" yourself. You'll discover any weaknesses in your security system that may have previously escaped your notice.
Lock up your home, even if you go out only for a short time. Many burglars just walk in through an unlocked door or window.
Change all the locks when you move into a new house or if you lose your keys.
For the most effective alarm system, conceal all wiring. A professional burglar looks for places where they can disconnect the security system.
Your house should appear occupied at all times. Use timers to switch lights and radios on and off when you're not at home.
If you have a faulty alarm that frequently goes off, get it fixed immediately and tell your neighbors that it's been repaired. Many people ignore an alarm that goes off periodically.
A spring-latch lock is easy prey for burglars who are "loiding" experts. Loiding is the method of slipping a plastic credit card against the latch tongue to depress it and unlock the door. A deadbolt defies any such attack. It is only vulnerable when there is enough space between the door and its frame to allow an intruder to use power tools or a hacksaw.
Before turning your house key over to a professional house cleaner for several hours, make sure the person is honest and reputable. Check all references thoroughly, or the firm's reputation.
Instead of keeping a spare key in a mailbox, under the doormat, or on a nail behind the garage, purchase a "lock-box" which is most secure, $30 at Home Depot and keep the code in your smart phone under a label only you would know.
Don't leave notes for service people or family members on the door. These act as a welcome mat for a burglar.
If the entrances to your home are dark, consider installing lighting with an infrared detector. Most thieves don't want to be observed trying to get in a door.
Talk to your neighbors about any suspicious people or strange cars you notice lurking about.
To keep your tools from being stolen, paint the handles. Thieves avoid items that are easy to identify.
Trees located near windows or shrubbery that might shield a burglar from view can be major flaws in your home-protection plan. Consider your landscaping plan in light of your protection needs.
Ask for credentials from any sales-person who requests entry to your home. Ask that their ID be pushed under the door. Many professional burglars use this cover to check out homes. If you're doubtful, check with the person's office before letting him or her in.
Do not list your full name on your mailbox or your entry in the telephone book. Use only your initial and your last name.
If someone comes to your door asking to use the phone to call a mechanic or the police, keep the door locked and make the call yourself.
Dogs are good deterrents to burglars. Even a small, noisy dog can be effective -- burglars do not like to have attention drawn to their presence. Be aware, however, that trained guard dogs do not make good pets. Obedience training and attack training are entirely different, and only the former is appropriate for a house pet.
