Put obvious, indelible markings on appliances. Obvious markings, that cannot be removed, deter the burglar because the items are easily identified. Put up a visible notice that all property has been marked, such as the Project ID sticker. Invest in alarms for your home. There are many types and price ranges to choose from.
Some alarms automatically phone the local police department to report a break-in.
Many police departments have crime prevention officers that will come to your home or business and show you how to make it more secure. With vertical sliding windows, screw a block into the guide rails to limit how far a window can be opened. Don't let strangers into your home. Motion detector activated lighting can alert you to the presence of people on your property. They may startle a burglar away.
