As people's requirements for various aspects of the access control system continue to increase, the application range of access control is more and more extensive. The application of the access control is not limited to a single entrance and exit control, but also requires it to be applied not only to the access control, attendance management, security alarm, parking lot control, elevator control, building automation, etc. of the intelligent building or intelligent community. Various control functions such as linkage control with other systems. Therefore, access control is different depending on the function, and its price is different. So what factors do we need to consider when choosing an access control?
First, access control selection criteria
The standard we choose for access control system is: the first is quality (measured by reliability, stability, low failure rate); the second is enough (regular manufacturers' products can generally meet the needs of more than 98% of users, standard functions can be , the function is not the more the better, the simple and practical is the best); the third is the price (choose the performance / price ratio of the good product).
Second, production history
From time to time, European and American products generally have a long time for R&D and production (generally more than 10 years). The products are improved and perfected through many generations, the quality is more stable and reliable, and the products are serialized. The R&D and production time of Hong Kong, Taiwan and domestic products is relatively high. Short (generally below 1-6 years), Taiwan's products are a little longer than domestic ones, generally small and medium-sized systems, the brand's different quality performance is quite different.
Third, the scale of production
European and American access control products are generally produced by professional manufacturers, product scale and standardization, manufacturers are only responsible for research and development and production, and then through the worldwide agents and system integrators to sell and engineering installation, manufacturers are not directly The end user, not directly to the user installation and technical services, but through the agency system to complete.
Taiwan's products are sold through European and American methods, but domestic brands are relatively small in scale. Most of the products are self-produced, sold, and installed by themselves. The scale of production is relatively small, which is why domestic products are difficult to grow.
Fourth, the price
Generally speaking, the price of European and American products is 4-5 times higher than the price of Hong Kong and Taiwan and domestic products. Generally, the projects of large and important places are mostly European and American products. The user requirements are more considering the reliability and stability of the system. In particular, some large and medium-sized projects use imported European and American products. Hong Kong, Taiwan and domestic products are generally used in small and medium-sized projects and where simple requirements are required. National products will occupy more market share with the improvement of quality.
Five, function
The development of access control technology has been developed from Europe and the United States. In the United States and Europe, there are very standard standards for access control technology. The products produced by various manufacturers are also regulated according to uniform performance standards. For example, if the United States meets UL and FCC. The standard must have the corresponding standard functions of the product hardware and software and the security of the system, and these conditions are quite high standards, satisfying the needs of 98% of users, so users can safely choose the equipment as long as they have the above criteria. Purchasing, without having to bother to examine the function of the access control.
Hong Kong and Taiwan and domestic access control products were relatively simple products, such as independent access control products, integrated access control products, etc., and later developed into networked access control products, but the time is still short, reliability and stability in the Zhongda access control system. Sex has yet to be improved.
Sixth, security
Generally speaking, the safety design of European and American products is relatively strict. This is because European and American countries have very strict safety industry standards. In particular, system manufacturers are generally not open to the underlying interface protocols of their products. This is mainly from the perspective of security. considerate. Because domestic manufacturers do not have strict industry standard specifications, product safety cannot be guaranteed. Generally, as long as the products are purchased, the underlying interface protocol can be provided. The management software can also be rewritten according to the needs of users. The surface seems to be more flexible, and the actual hidden security. Hidden troubles, because software and hardware, the software just written takes time to test, the security and stability of hardware and software is the most important, so try to use time-tested products.
Seven, cost
The same is the import of access control products, the price of the products is also quite different, the introduction of domestic products are more mainstream products abroad, performance and quality are better, but the price may differ by more than 1 times, which requires users to carefully compare and Identification, regardless of the grade of the product has a relatively good price-performance choice. The imported products we have used, such as KERI, SECURAKEY, DDS, etc., are all good choices.
The quality of domestic products is quite different, and the price difference is about 1-2 times. The price/performance ratio is also very different, and users need to compare them carefully.
