Recent studies have shown that in the United States, three out of four cars do not have the necessary utilities installed to prevent car theft. In addition to this, one out of four car owners, or 25 percent of those who have these utilities installed do not activate them. This figure, although alarming, is not surprising, as it can help explain the high incidence of car jacking and car theft in the country. Given this, much has been written about how people can prevent car theft, however, much of what has been written consist of tips that car owners could do like making sure that they park in well-lit places. In addition to this, there is also not much literature on how people can use car alarms to help them prevent car theft. This has led to situations in which people dismiss the value of having an effective car security alarm systems, because they do not know much about them.
Given the determination of car thieves, the manufacturers of alarm systems have come up with utilities that prevent thieves from stealing your vehicle. Manufacturers have developed alarm systems that are equipped with motion sensors or impact sensors that give off a loud siren if somebody gets too near your automobile or tries to steal it. They also manufacture steering wheel locks that prevent anyone from driving off with your car, unless they have a code or a key.
