Защита дома от краж: методы и системы безопасности.

Set of practices to protect homes against crime

Home security includes both the security hardware placed on a property and individuals' personal security practices. Security hardware includes doors, locks, alarm systems, lighting, motion detectors, and security camera systems. Personal security involves practices like ensuring doors are locked, alarms are activated, owning a Dog, windows are closed, and extra keys are not hidden outside. According to an FBI report, 58.3% of burglaries in the United States involved forcible entry. Per the most recent statistics, the average burglary in the United States takes about 90 seconds 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 neighbours.

Marie Van Brittan Brown was an African American inventor who invented one of the first home security systems in 1966, along with her husband Albert Brown. They jointly applied for a patent, which was granted in 1969.

One main component to home security is finding an area for easy programming and user interaction. A control panel is implemented to arm and disarm a home security system. The control panel is the main connection to the alarm company monitoring a home. It typically features a touchpad or buttons to easily maneuver the system, and some newer systems also feature voice control or wireless remotes (key fobs).

Door and window sensors are also implemented in most home security systems. One part of the system is installed on the door or window itself while the other part is installed on the frame of the door or window. The two part system connects securely when a door or window is closed, creating a security circuit.

Within the United Kingdom it is standard practice to have a 5 lever British standard mortise lock fitted to a wooden door, this will ensure that the property is compliant within the insurance sector. A cylinder that is anti snap fitted to a uPVC door will prevent lock snapping.

Smart homes have started to become more advanced. New devices are emerging with the specific purpose of simulating presence. They do this through movement simulation by using light and shadow effects at night or sound simulation at daytime.

Surveillance cameras used in houses are IP cameras or closed circuit. IP cameras connect over the internet and stream to users’ phones using a Wi Fi connection. Closed circuit, or CCTV cameras, stream through wired or wireless links. These cameras stream live footage to users, allowing them to watch for suspicious activity. Current cameras feature abilities such as motion detection and two way audio, allowing users to receive notifications of activity and speak and listen through the camera. Home surveillance cameras used for security purposes have become more accessible, but have sparked security concerns from consumers.

Surveillance cameras and motion sensors work hand in hand with allowing home owners to keep an eye on areas of their home that they might not have access to at the moment. Motion sensors create zones which cannot be accessed without sounding an alarm. Most cameras do now have a motion detection function, with some brands having thermal detection so they only activate when sensing a heat signature. This function is used so cameras do not pick up false alarms from trees blowing in the wind.

Glass break detectors are usually installed near glass doors or a window front of a store. This equipment uses a microphone to detect when a pane of glass is broken or shattered. By monitoring the sound and vibrations the alarm only reacts to sounds above a certain threshold to avoid false alarms. with the DIY home security market worth $1.5 billion. While the market for home security is expanding, especially with cable TV and Internet service providers introducing their own security and home automation products, it is a fragmented market, with "a massive array of large and small rivals." The US market leader is ADT with more than 6 million households subscribed. The FBI reported that 1.7 million homes were burglarized in 2014. The same report shows that an estimated loss of $3.9 billion was suffered by the victims in the same year. Overall, when the average value was applied to the estimated number of burglaries, the average dollar loss per burglary offense was $2,251. Roughly, there are 2.5 million burglaries a year with 66% being home break ins. Police typically only solve 13% of break in crimes due to lack of information and witnesses.

It is reported that 53% of break ins occur during the day and 47% occur at night. Break ins are 6% more likely to occur between 6am and 6pm while most are out of the house. With only 17% of homes being equipped with home security systems, many burglars are attracted to homes lacking a system. 95% of break ins require some type of forceful entry (breaking a window, lock picking, kicking in doors). Some common tools used for break ins are pliers, screwdrivers, and hammers. This makes it hard to see break ins coming since they are common household tools. A study at UNC Charlotte concluded that burglars are commonly males under the age of 25. 12% of burglars admitted to planning their break in in advance while 41% said it was an impulsive decision. Also, many burglars admitted they consider factors like proximity to traffic. 83% of burglars said they look for evidence of an alarm system, and 60% said they do not break in if they see one is installed.
