Home security is both the security hardware in place on a property as well as personal security practices. Security hardware includes doors, locks, alarm systems, lighting, motion detectors, security camera systems, etc. that are installed on a property; personal security involves practices such as ensuring doors are locked, alarms activated, windows closed, extra keys not hidden outside, etc.
According to an FBI report, 58.3 percent of burglaries in the United States involved forcible entry. A typical burglary lasts for about 8 to 12 minutes and, on average, a burglar will break into a home within 60 seconds. Common security methods include never hiding extra keys outside, never turning off all the lights, applying small CCTV stickers on doors, and keeping good tabs with neighbors.
