Eight points must be seen when choosing an ideal access controller

The access controller is the center of the access control system, just like the engine in a car. The performance of the access control controller directly affects the stability of the access control system, and the stability of the system directly affects the safety of customers' lives and property.

  Currently, there are many access control controller products on the Chinese market, with almost the same functions, but the quality is uneven. Therefore, the product selection is particularly important for engineering companies. So how to choose a high-quality access controller?

  Our principle is "stable and reliable performance, practical functions, price advantage, sustainable service capability".

1. Anti-crash design

  The access controller crashes like a car engine stalls. No matter how powerful the function of the controller is, if there is a crash, the controller will not work, and no function will be reflected. If there is a crash in the application, it means that the area controlled by the controller cannot be accessed normally, and it may even cause serious safety hazards and immeasurable losses.

Second, the capacity of the relay

  The output of the access controller is controlled by a relay. When the controller is working, the relay must be opened and closed frequently, and an instantaneous current flows through each time it is opened and closed. If the capacity of the relay is too small, the instantaneous current may exceed the capacity of the relay, which will soon damage the relay. In general, the capacity of the relay should be more than 3 times greater than the peak current of the electric lock.

Three, the protection of the controller

  The working voltage of the components of the access control controller is generally 5 volts. If the voltage exceeds 5 volts, the components will be damaged and the controller will not work. This requires that all input and output ports of the controller have dynamic voltage protection, so as to prevent possible large external voltage from being loaded on the controller and damage the components.

Fourth, the adaptive function of the front-end input device

  Because different users and different applications have different requirements for the input device of the access control system. This requires the access controller to be compatible with a variety of front-end input devices (for example: support Wiegand26Bit, Wiegand32Bit, Wiegand27Bit, ABA (second track), object recognition technology, fingerprint recognition technology, inductive IC card, password keyboard, etc.). And can automatically detect the input front end.

Five, the reliability of management software

  A high-quality access control system not only requires high-quality controllers, but also requires high-reliability and fault-tolerant management software support.

Six, after-sales service should include two aspects

  One is a complete technical support system, including the ability to provide localized pre-sales support and after-sales technical support; the other is strong follow-up research and development capabilities to ensure the continuity and advancement of the product.

Seven, quality certification

  Access control controllers and system products sold in China must pass the "type inspection" (not commissioned inspection) conducted by the Security and Police Electronic Product Inspection Center of the Ministry of Public Security of China, and the software shall pass the inspection of the China Software Evaluation Center. Production should be produced by professional electronic manufacturers with ISO9000 certification, especially military enterprises.

8. Price

  The experience of the IT industry tells us a truth: a powerful company must be able to provide the society with high-quality and price-competitive products to meet the needs of customers, and at the same time, it can ensure that engineers can obtain reasonable profit margins.
