The monitoring system allows security personnel to intuitively grasp the site situation and analyze it through video playback. The TV monitoring system is an important part of the applied TV system and also an important part of the security system. At present, TV monitoring system has been organically combined with anti-theft alarm system to form a more reliable monitoring system.
Baidu Encyclopedia-What does the security system include?
The full name of security system is public security system, which aims to protect personal and property safety, information and communication safety, and achieve the purpose of loss prevention and crime prevention.
an anti-theft alarm system
The anti-theft alarm system is used to detect (invade) personnel activities in the protected area through various intrusion detectors installed on the protection site, and once an intrusion is found, an alarm message will be generated to achieve the purpose of anti-theft.
the second TV monitoring system
The TV monitoring system uses image monitoring as a means to monitor and record live images in real time. The monitoring system allows security personnel to intuitively grasp the site situation and analyze it through video playback. Early TV monitoring system is an important part of applied TV system and security system. At present, TV monitoring system has been organically combined with anti-theft alarm system to form a more reliable monitoring system.
Three-entrance control system
Entrance control system, also known as access control system, is used to control personnel's entry and exit, as well as their activities in the prevention area. In the prevention area, you must use all kinds of cards, passwords or biometric technology to be identified and confirmed by the control device before you can pass. The parking lot management system actually belongs to the entrance and exit control system.
Four-building security intercom system
The building security intercom system provides two-way call or visual call, remote unlocking and alarm functions for visitors and indoor personnel.
Five-electronic patrol system
In a large building or yard, there are many entrances and exits, and the people coming and going are complicated, so it is necessary to have special personnel to patrol. Patrol stations should be set up in more important places to patrol regularly. Electronic patrol system means that security personnel send back signals to the central control room at the specified time and place on the specified patrol route to show normal.
First, the basic concept of safety precautions
● The general concept of safety precautions
According to the current Chinese dictionary, the so-called safety means no danger, no infringement and no accidents; The so-called prevention means preparedness, alert, and preparedness means preparing for an attack or avoiding victimization, and alert means preparedness and protection.
Based on the above explanations, can we define security as follows: prepare and protect to cope with attacks or avoid being victimized, so as to make the protected object in a safe state without danger, infringement and accidents? Obviously, security is the purpose, and prevention is the means. It is the basic connotation of security prevention to achieve or realize the purpose of security through preventive means.
● Two Safety concepts
Safety in Chinese has two interpretations in English: safety and Security. The modern advanced English-Chinese dictionary published by Oxford University mainly explains the word Safety: safety, safety, security, insurance (lock), insurance (box), etc. The main interpretation of the word "Security" is: security, no danger and no worries, providing things that are safe and exempt from danger or worries, collateral, collateral, security (police), security (troops) and so on.
In fact, Security in Chinese is a kind of security in a broad sense, which includes two meanings: one refers to the security of natural or quasi-natural attributes, which corresponds to the Safety in English, and the other refers to the security of social humanity, that is, the security with obvious attributes, which corresponds to security. The destruction of the safety of natural or quasi-natural attributes is mainly not caused by people's purposeful participation; The destruction of social humanity is mainly caused by people's purposeful participation. Therefore, in a broad sense, Security should include two meanings: Safety and Security, and what we often say about security mainly refers to the narrow sense of security security, which is usually called "security" abroad.
● loss prevention and crime prevention-the inherent meaning of safety prevention
in the west, the word "safety prevention" is not used, but the concept of loss prevention and crime prevention is used. Just as Chinese security and prevention are used together to form a new compound word, in the west, Loss Prevention and Crime Prevention are also used together. Loss prevention and crime prevention constitute two aspects of a Safety/Security problem. In foreign countries, Loss Prevention usually refers to the focus of social security industry, while Crime Prevention is the focus of police law enforcement departments. The organic combination of the two can ensure social stability and security. In this sense, loss prevention and crime prevention are the essential contents of safety prevention.
to sum up, security is not only a public security business (police executive department), but also a social public and social economic undertaking. Their development and progress not only depend on the development and progress of science and technology, but also provide and create a good social environment for the progress and development of science and technology.
● Dagong * * * security concept
The so-called Dagong * * * security concept is a comprehensive security concept, which is to provide comprehensive security services that are always safe and safe everywhere for social security. The so-called social security service guarantee system is a comprehensive security system project (hardware and software) and management service system jointly implemented by the government, government organizations and all walks of life (by no means the Ministry of Public Security, let alone an institution within the law enforcement department of the Ministry of Public Security). The comprehensive security that the public needs includes not only the narrow sense of "security precautions" with anti-theft, anti-robbery, anti-invasion and anti-destruction, but also fire safety, traffic safety, communication safety, information safety, human body protection, medical assistance and gas leakage prevention.
second, the three basic means of security: civil air defense, physical defense and technical defense
security is a part of social security, and security industry is a branch of social security industry. As far as preventive measures are concerned, safety precautions include three categories: manpower precautions, physical precautions and technical precautions. Among them, human prevention and physical prevention are the ancient traditional prevention means, which are the basis of safety prevention. With the continuous progress of science and technology, these traditional prevention means are also constantly integrated into the content of new technology. The concept of technical prevention is a new concept in the process of modern science and technology (initially electronic alarm technology) being used in the field of security prevention and gradually forming an independent prevention means. Due to the continuous development and popularization of modern science and technology, the concept of "technical prevention" has become more and more popular, more and more recognized and accepted by police law enforcement departments and the public, so that it has become a new vocabulary with high frequency of use, and the content of technical prevention has been constantly updated with the progress of science and technology. In today's era of rapid development of science and technology, it can be said that almost all high-tech will be transplanted and applied to security work sooner or later. Therefore, the position and role of "technical prevention" in security prevention technology will become more and more important, which has brought a new revolution in security prevention.
the three basic elements of security are detection, delay and response. Detection refers to sensing the occurrence of explicit and implicit risk events and giving an alarm; Delay refers to the process of prolonging and delaying the occurrence of risk events; Response refers to the rapid actions taken by organizational forces to stop the occurrence of risk events. Among the three basic means of security, in order to achieve the ultimate goal of prevention, we should carry out work and take measures around the three basic elements of prevention, such as detection, delay and response, in order to prevent and prevent the occurrence of risk events. Of course, the three preventive measures play different roles in the process of implementing prevention.
The basic human defense means (civil air defense) is to use people's own sensors (eyes, ears, etc.) to detect, find the target that hinders or destroys safety, and respond; Use sound warning, intimidation, obstacle setting, weapon counterattack and other means to delay or prevent the occurrence of danger, and send out a signal for help when one's own strength is insufficient, in order to expect to make further response, stop the occurrence of danger or deal with the danger that has occurred.
the main function of physical prevention (physical prevention) is to delay the occurrence of danger and provide enough time for "reaction". Modern physical protection is no longer the passive protection of physical barriers, but more and more high-tech means are adopted. On the one hand, the possibility for physical barriers to be destroyed is reduced, and the delay time is increased. On the other hand, it also increases the detection and reaction functions of the physical barrier itself.
technical prevention means can be said to be the functional extension and strengthening of human prevention means and entity prevention means, and it is the supplement and strengthening of human prevention and entity prevention in technical means. It should be integrated into human prevention and entity prevention, so that human prevention and entity prevention can continuously increase the high-tech content among the three basic elements of detection, delay and response, and constantly improve the detection ability, delay ability and response ability, so that the prevention means can really play a role and achieve the expected purpose.
the three basic elements of detection, delay and response are interrelated and indispensable. On the one hand, the detection should be accurate, the delay time should be appropriate, and the response should be rapid; On the other hand, the total time of reaction should be less than (at most equal to) the total time of detection plus delay.
iii. security technology and security technology prevention
security technology is a special technology used for security prevention. in foreign countries, security technology is usually divided into three categories: Physical Protection, Electronic Protection and Biometric Protection. Physical prevention technology here mainly refers to physical prevention technology, such as buildings and physical barriers and various physical facilities, equipment and products (such as doors, windows, cabinets, locks, etc.) that match them; Electronic prevention technology mainly refers to electronics, communication, computer and information processing and related technologies, such as electronic alarm technology, video monitoring technology, access control technology, computer network technology and its related software and system engineering. Biometric prevention technology is the product of the combination of forensic science material evidence identification technology and pattern recognition in security prevention technology. It mainly refers to a special technical category that uses the biological characteristics of human body to prevent security technology. Now, fingerprint, palm print, eye print, voiceprint and other identification control technologies are widely used.
security technology prevention is a security service guarantee system with the combination of detection, delay and response in an orderly way, which is based on security technology, based on manpower prevention, and by means of technical prevention and entity prevention. He is a public security business and social public enterprise aimed at preventing losses and crimes. For police law enforcement departments, security technology prevention is a public security business that uses security technology to carry out security prevention work; For social and economic departments, security technology prevention is an industry that provides a kind of security service for the public by using security technology. Since it is an industry, there must be product research and development, systematic design, engineering construction, service and management.
iv. professional system of security technology
as a branch of social security science and technology, security technology prevention has its relatively independent technical content and professional system. According to the technical status and future development of China's security industry, We can classify security technologies according to different disciplines, product attributes and application fields as follows:
● Intrusion detection and anti-theft alarm technology
● Video monitoring technology
● Identification and control technology of entrance and exit targets
● Alarm information transmission technology
● Anti-robbery and anti-theft alarm technology of moving targets
● Emergency alarm technology of community security and social assistance
● Physical protection.
