"We all want to keep our families as safe as possible. We have locks on our doors, alarm systems, and dogs of all sizes willing to protect us. Many of us participate in a neighborhood watch and work with local police departments; these are effective systems that have been in use for decades. Today, you can also use some high-tech tools and approaches to your neighborhood watch to increase safety."
