Types of Security Systems

Security systems involve the use of various means, devices and sometimes also human force to protect individuals and property from various hazards such as fire, crime and loss. The available security systems can be classified into various types which, however, often overlap with one another. But since most of the available security systems are focused on protection from a specific hazard, it is highly important to distinguish between different types of security systems.

Some of the most common security systems include:

Home/residential security systems. It is a broad term which covers various aspects of home security and involves the use of a variety of means and devices. Among the simplest yet among the most effective home/residential security systems are locks, barred windows, fences, etc. Always ensure locks are approved to british standards. If you are conducting house extensions then ensure all the building controls and security measures are undertaken. In the recent decades, these systems were joined by technologically advanced and sophisticated equipment and technology which has dramatically improved security of households worldwide. Examples include fire alarms, carbon monoxide detectors, motion detectors, exterior lighting, etc., while apartment complexes often also use closed-circuit television monitoring of the entries, hallways and elevators as well as security guards. Neighbourhoods of larger cities may also employ patrol services or organize voluntary residential patrols.

Commercial security systems. Businesses are vulnerable to the same hazards than private residences but they are also at risk of industrial espionage, internal theft, work-related accidents and injuries, etc. Commercial security systems therefore involve the use of more sophisticated technologies and equipment such as automatic access-control systems, button alarms, card readers, etc. as well as trained security staff from reputable firms . A special category are security systems which are intended for small businesses that cannot afford highly sophisticated technology. Some of these systems are technologically on the level of home/residential security systems which, however, does not necessarily mean they are inferior to those used by large firms and companies.

Computer security systems. They are a type of security systems which deal with safety of information that is stored on computers and can even have a mobile printer fitted. Their main goal is to prevent theft and loss of information yet enable the user an easy access to information. Most types of computer security systems involve the use of specially designed programmes which offer protection from break-ins both physically and virtually. Since every security system is typically designed to offer protection against a specific threat, multiple computer security systems are often used.

Fire alarm systems. Devices which detect smoke and alert people in the building on the threat of fire are used in both residential areas and commercial establishments. Some devices may also include fire extinguishing system which further decreases the risk of fire damage and human casualties.

Personal safety systems. These are intended to increase personal safety by helping individuals to avoid potentially dangerous situations and to defend themselves if being physical attacked. Examples includes personal alarms, self-defence sprays, child locators, etc. Individuals who have a high risk profile such as kidnapping, assault, assassination or other criminal offences are usually also protected by one or multiple bodyguards.
