The access security system has the main purpose of preventing loss and preventing crime, so it must have high reliability. An access security system may not have an alarm during most of its operation, so there is no need for an alarm. The probability of an alarm requiring an alarm is generally small, but if the alarm system fails within this minimum probability , often means the arrival of disaster. Therefore, the access control security system must implement reliability design (redundancy design) and reliability management at all stages of design, construction and use to ensure high reliability of products and systems.
In addition, in the system design, equipment selection, commissioning, installation and other aspects are strictly implemented the national or industry-related standards, as well as the public security department's requirements for security technology prevention, the product must undergo a number of authoritative certification, and has many typical The user has been running normally for many years.
safety
Access control and security systems are used to protect people and property, so the system itself must be safe. The high security mentioned here refers to the natural or quasi-natural nature of the product or system. It should ensure the safety of equipment and system operation and the safety of the operator. For example, the equipment and the system itself must be able to prevent high temperature and low temperature. Warm, smog, mold, rain, and can prevent radiation, anti-electromagnetic interference (electromagnetic compatibility), anti-shock, anti-collision, anti-drop, etc., equipment and system operation safety also includes fire prevention, lightning protection, explosion-proof, Protection against electric shock, etc.; on the other hand, access control and security systems should also have the function of preventing human damage, such as: a protective housing with anti-destruction, as well as tamper alarm, short circuit and open circuit.
Feature
With the continuous improvement of various requirements of the access control system, the application range of the access control system is more and more extensive. The application of the access control system is not limited to a single entrance and exit control, but it is also required to be applied not only to the access control, attendance management, security alarm, parking lot control, elevator control, building automation, etc. of intelligent buildings or intelligent communities . A variety of control functions such as linkage control with other systems.
Scalability
The access control system should choose an open hardware platform with multiple communication methods, which lays a good foundation for the interconnection and integration between various devices. In addition, the system should have standardized and modular components and be flexible. Sex and extensibility.
