The access controller is the backbone 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. Therefore, it is very important to choose a high-quality access controller . So, how to choose an access controller? Jiahua Guardian summarizes the eight important factors for choosing an access controller:
I. Anti-Crash Design
The access controller crashes just like a car engine goes out. No matter how powerful the controller design is, if there is a crash, the controller cannot work, and no function can be reflected. If a crash occurs in the application, it means that the area controlled by the controller cannot enter and exit normally, and it may even cause serious security risks and immeasurable losses.
Second, the capacity of the relay
The output of the access controller is controlled by a relay. When the controller works, the relay should 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 quickly damage the relay. In general, the relay capacity should be more than 3 times the peak current of the electric lock.
Third, the protection of the controller
The working voltage of the components of the access 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 avoid possible large external voltages from loading the controller and damaging the components.
Fourth, the adaptive function of the front-end input device
Because different users and different applications have different requirements for the input devices of the access control system. This requires the access controller to be compatible with a variety of front-end input devices (such as: support for Wiegand26bit, Wiegand32bit, Wiegand27bit, aba (second track), physical recognition technology, fingerprint recognition technology, inductive IC card, password keyboard, watermark magnetic card, etc. ). And can automatically detect the input front end.
V. Reliability of management software
A high-quality access control system requires not only high-quality controllers, but also highly reliable and fault-tolerant management software.
Six, after-sales service
The first is a complete technical support system, including the ability to provide localized pre-sale support and post-sale technical support; the second is strong follow-up research and development capabilities to ensure that the product is sustainable and advanced.
Seven, quality certification
The sales of access control controllers and system products in China must pass the "type inspection" (not commissioned inspection) of the Ministry of Public Security's Security and Electronic Products Testing Center, and the software should pass the testing of the China Software Evaluation Center. Production should be produced by a professional electronics manufacturer with iso9000 certification, especially for military enterprises.
The experience of the IT industry tells us a truth: a strong company must be able to provide the society with high-quality products with price advantages to meet customer needs, and at the same time ensure that engineering companies can obtain reasonable profit margins.
