Access control system, also known as access control system. The main function is to realize the monitoring and control of the entrance and exit, as well as the management of personnel access information. In addition, by combining with attendance management, security alarm, parking lot control, elevator control, consumption management and other subsystems, it not only becomes an important guarantee for import and export safety, but also contributes to internal modern management. Therefore, the access control system should have a high degree of stability, choose an open hardware platform, support a variety of communication methods, and lay a solid foundation for the interconnection and system integration between devices. Great flexibility and extensibility.
1. Strong stability
"Stable" is the primary principle for the selection of access control systems. As far as possible, mature products that are in the leading position in the world should be considered. They have passed a number of authoritative certifications, and have many typical users. They have been operating normally for many years and have been highly recognized in the industry.
In terms of hardware, from the controller to the terminal identification equipment are mature and stable products. As the core of the system, the access control controller needs to support the offline working mode, and must use non-volatile memory chips such as flash, so that the information will not be lost when power is cut off or when it is impacted. The failure of the server and terminal identification equipment does not affect the normal operation of the system
As the management software that the system relies on, it should have a stable and reasonable database structure design, and use a real-time polling method with the hardware to maintain and monitor the communication connection and address query of the hardware to complete the integrity, reliability, and consistency of data.
2. Strong anti-destructive ability
Access control systems are used to protect people and property, so the system itself must be secure. The high safety mentioned here, on the one hand, refers to the natural or quasi-natural attributes of the product or system, which should ensure the safety of equipment and system operation and the safety of operators. On the other hand, the access control and security system should also have the function of preventing vandalism, such as: anti-dismantling alarm and so on.
3. Excellent compatibility
In order to facilitate future upgrades, expansion, and for anti-interference considerations, it is recommended to choose terminal identification equipment that conforms to international standards, rather than the wider the compatibility, the better. Some formats have some local advantages, but they do not conform to international standards, which will cause trouble for future upgrades, expansion, and anti-interference. The principle of "practical, stable, and standard-compliant" should be adhered to.
4. Flexible scalability and economy
It is recommended that the registration card authority needs to reach 30,000, which can meet the storage capacity requirements of most customers, and facilitate attendance statistics and enterprise scale expansion. The main equipment should adopt a modular design and adopt advanced wiring methods, and the future system expansion can be realized through software and hardware upgrades without making too many changes to the system.
5. Powerful software management functions
As the application range of access control system becomes more and more extensive, it is required to realize linkage control function with other systems such as attendance management, security alarm, parking lot control, elevator control, consumption management, CCTV linkage, online patrol, etc. Therefore, the system software should have video interface, and supports extended functions.
6. Easy to maintain
The system should be easy to install and configure, simple and popular to use, and have unified network management capabilities for easy maintenance.
7. Buy mature brand products from the agent designated by the manufacturer
Only mature brands can ensure a complete and powerful service system, which includes two aspects: one is technical support for project implementation and thoughtful after-sales service; the other is reliable follow-up research and development capabilities to ensure the continuity and compatibility of new and old products.
While buying from an agent can have reliable quality and perfect service, buying from other channels may have a lower price, but technical support and after-sales service may not be enough.
Eight, product appearance
With the improvement of people's aesthetic standards, while pursuing functional and practical, its appearance design can be used as one of the reference standards, in order to achieve additional functions of visual enjoyment.
