One of the most intelligent security systems available today is the access control system. This system is designed to allow access to closed areas only by persons with appropriate access authorization. The main purpose of the system is to prevent unauthorized access of outsiders to the rooms or the protected zone.
The access control system allows identification (identification) of employees and guests entering and leaving the protected area. This system can be applied both to a single entry point and to the entire system of doors within the territory, depending on the goals of those who use it.
In the modern world, access control electronic systems are recognized as the most reliable among security systems. Recent innovations in this field are particularly noteworthy. Today's advanced electronic systems not only read code from plastic cards, they are also programmed with information such as biometric indicators of a person: fingerprints, iris of the eye. Such private information is unique, individual for each specific person. Therefore, this information is the best information for personal identification.
The working principle of the access control system is as follows: Any person wants to enter the protected area. The information read by the appropriate electronic device is sent to the database where all the information about the person is stored in the form of a request. The system, which takes into account the position and personal characteristics of that person, automatically decides whether or not to enter this or that person. A signal is then sent to the turnstile, gate or barrier to open or remain closed. In the second case, the security service is also notified: according to the instructions, they must react to an unauthorized access attempt.
State plates of cars can also act as a digital reading object of electronic equipment. The system can be successfully applied to the automation of vehicle access in the off-site areas of organizations. The access control system is adapted both to climatic conditions and to work with remote control.
In addition to all this, access control systems can perform additional functions. For example, they can be used to collect information about people's movements within the facility, keep records of working hours, manage working hours and other issues. Such control systems can also become part of an integrated security system that includes security, fire safety and video surveillance systems.
