[ Huaqiang Security Network News ] Access controllers are also popular nowadays. They are mainly used in the hub of access control systems, just like the engines in cars. The performance of the access controller directly affects the stability of the access control system, and the stability of the system directly affects the safety of the customer's life and property.
At present, there are many access control controller products in the Chinese market, and the functions are almost the same, but the quality is uneven. Therefore, the selection of products is especially important for the engineering company. So how do you choose a high quality access controller? We have shared the following experiences and shared them with you through years of practice.
Our principle is "stable and reliable performance, functional, cost-effective, localized sustainable service capabilities."
First, the anti-crash design <br> The access controller crashes like a car engine stalls. Regardless of the powerful design of the controller, 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 is not able to enter and exit normally, and may even cause serious safety hazards and immeasurable losses.
Second, the capacity of the relay <br> The output of the access controller is controlled by the relay. When the controller is working, the relay should be opened and closed frequently, and an instantaneous current is passed every time it is opened and closed. If the relay capacity is too small, the instantaneous current may exceed the capacity of the relay and will quickly damage the relay. In general, the relay capacity should be greater than 3 times the peak current of the electric lock.
Third, the protection of the controller <br> The operating 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 to prevent possible external large voltages from being loaded onto the controller and damaging the components.
Fourth, the adaptive function of the front-end input device <br> Because different users, 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 (such as: support Wiegand26Bit, Wiegand32Bit, Wiegand27Bit, ABA (second track), object recognition technology, fingerprint recognition technology, inductive IC card, PIN pad, watermark magnetic card, etc. ). And can automatically detect the input front end.
V. Reliability of Management Software <br> A high-quality access control system requires not only high-quality controllers, but also highly reliable and fault-tolerant management software support.
6. After-sales service should include two aspects:
The first is a complete technical support system, including the ability to provide localized pre-sales support and after-sales technical support; the second is a strong follow-up research and development capabilities to ensure product continuity and advancement.
VII. Quality Certification <br> The sales of access controllers and system products in China must pass the “type inspection†(not commissioned inspection) of the Safety and Police Electronic Products Testing Center of the Ministry of Public Security of China. The software should pass the test of China Software Testing Center. . Production should be produced by professional electronic manufacturers with ISO9000 certification, especially for military enterprises.
Eight, the experience of the price IT industry tells us a truth: a strong enterprise must have the ability to provide high-quality products with competitive price to meet the needs of customers, while ensuring that the engineering firm can obtain reasonable profit margins.
