Be a friendly and observant neighbor: Neighborhoods with a “community watch” where each person is looking out for the next provide a sense of security. Generally people know each other and who lives where. This activity makes it easier to talk about crime and helps homeowners to solve problems. Let neighbors know that you are crime conscious, and encourage them to be so, too. Provide your neighbor with contact information if you are leaving on vacation so that they can be in touch, should there be unusual or unexpected activity around your home.
Be discreet: While you do want neighbors to be informed to some degree, adverting more widely that you will be away from your home is less desirable. When seeking to find a house sitter or pet sitter, avoid advertising the dates of your travel. With an increase in social media and local email lists, people who are outside of your immediate circles could gain access to your plans and make use of that information.
Put on a good show: When you are going to be away from home for any period of time, one deterrent might be to make it look like someone is home. Often people who break in are simply looking to steal valuable items and prefer not to encounter people at all. Keep shades as they would normally be open or closed, and use timers to control lights and even music. Increasingly, “smart home” technology can enable homeowners to control the environment from a distance. Consider stopping deliveries or better yet, have someone stop by daily or stay in the home to pick up mail and newspapers, and to check on the house while you are gone.
Get a dog: In addition to companionship, a dog could be an excellent deterrent to a burglar. Barking serves as an alarm, helping to detect an intruder as well, but often seasoned criminals know how to deal with dogs by feeding them treats (sometimes laced with poison) or locking them in a room. Still, this added unknown might keep a less determined stranger away.
