What are the requirements of modern security system for property security personnel?

Security Requirements In order to prevent all kinds of theft and violence, it is essential to establish a security system in the building. In the past, people locked the door after work. Nowadays, with the rapid development of science and technology, various new criminal means have put forward many new topics for the security system. At the same time, with the advent of the information age, the content of security system has a new meaning. At first, the content of safety was to protect personal and property safety. Now, the protection of important documents, technical data and drawings is becoming more and more important. Entering the information society today, computer systems have penetrated into every corner of all walks of life, and a large number of files and data exist in computers, which need more protection. There are more and more cases in which the financial industry uses computers to steal huge amounts of money; In the technical field, there are more and more espionage activities that obtain technical information and intelligence through computers. Therefore, the protection of computer system has become an important content of security system. In an intelligent building with information automation and office automation, there are many levels of personnel and complex components. We should not only guard against external personnel, but also strengthen the management of internal personnel. Important places and articles need special protection. Therefore, modern architecture needs a multi-level and three-dimensional security system. From the process of preventing criminals from invading, the security system should provide the following three levels of protection. (1) External Intrusion Prevention External Intrusion Prevention is to prevent irrelevant personnel from invading the building from the outside. For example, prevent criminals from invading buildings from windows, doors, skylights, ventilation pipes, etc. Therefore, the purpose of this line of defense is to exclude criminals from the protected area. (2) Regional protection If criminals break through the first line of defense and enter the building, the security system should provide the second layer of protection: regional protection. The purpose of this protection level is to detect whether someone illegally enters some areas, and if so, send an alarm message to the control center, and the control center will handle it accordingly. (3) The third line of defense for target protection is the protection of specific targets. Such as safes and important cultural relics, are listed as the protected objects at this level. This is another protective measure after the failure of the previous two defensive measures. In a word, it is best for the security system of the building to detect the invasion intention and actions of criminals in time, so as to take measures to "defend against the enemy" as soon as possible. When a criminal invades the prevention area, security personnel should know his activities through the security system. When the criminal touches the target, the last line of defense of the security system should come into play immediately. If all preventive measures fail, the security system should also have information records before and after the crime, so as to help relevant personnel analyze the crime process. This is the task of intelligent building security system.
