Now access control devices are more popular, it is mainly used for door access control systems, as the function of engine in the car. Access controller performance directly affects the stability of the access control system, and the stability of the system directly affect the customer's life and property security.
At present, many access control products in the Chinese market, the function is almost the same, but the quality of uneven. So the product selection for the product is particularly important. So how to choose high-quality access control controller? We share the following experiences with many years of practice to share with you.
Our principle is "stable and reliable performance, functional and practical, price advantage, the localization of sustainable service capabilities."
Access control & attendance system CU-F370
1, Anti-crash design
The access controller crashes like a car engine. Regardless of the controller design and then powerful, if the crash, the controller can not work, any function can not be reflected. If there is a crash in the application, it means that the control of the area can not be normal access, and may even cause serious security risks and immeasurable losses.
2, The relay capacity
The output of the access controller is controlled by the relay. When the controller is in operation, the relay must be opened and closed frequently, and each time the opening and closing has an instantaneous current through. If the relay capacity is too small, the instantaneous current may exceed the capacity of the relay and will soon damage the relay. The general situation relay capacity should be greater than the electric lock peak current 3 times more.
3, The protection of the controller
Access controller components of the operating voltage is generally 5 volts, if the voltage exceeds 5 volts will damage the components, leaving the controller can not work. This requires all the controller input and output are dynamic voltage protection, so as to avoid possible external large voltage load to the controller and damage the components.
4, The front-end input device adaptive function
Because different users, different applications on the access control system input device requirements are different. This requires the access controller to be compatible with a variety of front-end input devices (such as: support Wiegand26Bit, Wiegand32Bit, Wiegand27Bit, ABA (second track), identification technology, fingerprint recognition technology, sensor IC card, password keyboard, watermark ). And can automatically detect the input front.
5, The reliability of management software
A high-quality access control system requires not only high-quality controllers, but also high reliability and fault-tolerant management software support.
6, After-sales service should include two aspects:
First, a complete technical support system, including the ability to provide localized pre-sales support and after-sales technical support; Second, a strong follow-up research and development capabilities to ensure that products are sustainable and advanced.
7, Quality certification
Access control and system products sold in China must pass the Chinese Ministry of Public Security and police electronic products testing center "type test" (not commissioned inspection), the software should be detected by the China Software Testing Center. Production should be ISO9000 certified by the professional production of electronic manufacturers, especially for military enterprises as the best.
IT industry experience tells us a truth: a strong business must have the ability to provide high-quality products for the community to meet the needs of customers, while ensuring that the project can get a reasonable profit margins.
