SpainHow to choose a high quality access controllers
Release date:2016-01-26
Access Controller is the central access control system, the same as the human brain. Access controller performance 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.
Currently on the Chinese market access controllers many products, it features almost the same, but the quality is uneven. Therefore, the selection of contractors for the product is particularly important. So how to choose high-quality access control it? We summarize the following experience gained through years of practice to share with you:
Our principle is "stable and reliable performance, functional and practical, there is a price advantage, the sustainability of localization service capabilities."
First, anti-crash design
Access Controller crashes like the same car engine flameout. No matter how powerful controller design function, if crash, the controller does not work, any function can not be reflected. If the application crashes, it means that the controller can not properly control access to the area, and may even result in the loss of a serious security risk and immeasurable.
Second, the capacity of the relay
Access controller output is controlled by the relay. When the controller is working, the relay to the frequent opening and closing, and each has an open timely instantaneous current. If the relay capacity is too small, the transient current may exceed the capacity of the relay, the relay will soon damage. Normally the relay capacity should be more than three times more than the peak current of the electric lock.
Third, the protection controller
Access controller operating voltage component is generally 5 volts, if the voltage exceeds 5 volts will damage the components, leaving the controller does not work. This requires that the controller of all input and output port has a dynamic voltage protection from the outside world may be a large voltage is applied to the controller and damage to components.
Fourth, the front-end input devices adaptive function
Because different users, different applications to access systems require different input devices. This requires access controller compatible with a variety of front-end input devices (such as: support Wiegand26Bit, Wiegand32Bit, Wiegand27Bit, ABA (second track), object recognition technology, fingerprint recognition technology, IC card, password keyboard, magnetic cards and other watermark ). And can automatically detect the input end.
Fifth, the management software reliability
A high-quality access control system not only need high-quality controllers, but also require high reliability management software supports fault-tolerant.
Sixth, after-sales service should include two aspects:
The first complete technical support system, including the ability to provide localized support and after-sale pre-sales technical support; the second is a powerful follow-up research and development capabilities, to ensure that products can have continuity and advanced.
Seven, quality certification
Access control and systems products sold in China must use electronic product testing center "type test" (not trust test) by China Ministry of Public Security Police, the software should by China Software Testing Center of detection. Production should have ISO9000 certification of professional electronics manufacturers production, particularly in the military enterprises for the best.
Eight, price
Experience in the IT industry, tell us a truth: a powerful enterprises have the ability for the community to provide high-quality competitively priced products to meet customer needs, while ensuring engineering companies from which you can get a reasonable profit margin
