1. Import controllers that import controllers will be better in product stability and maturity are all very good. However, the price is expensive, and because of geographical disparity, the timeliness of the service will not be good, and the service cost will be high. At the same time, due to the differences in cultural background, the foreign users' needs and requirements for access control and management are different from China's national conditions. Many features are simply not suitable for China's national conditions and the needs of Chinese users. Of course, many Chinese access controller manufacturers have small production scales and weak design capabilities. There are few successful application cases, and engineering firms should also choose carefully. Many Chinese access controller manufacturers, in order to sell their own products, use fraudulent sales made in Taiwan, the United States, Canada, and other countries. In fact, product quality has great problems. This phenomenon should also be treated with caution.
2. The reader's compatibility is as broad as possible. Some controllers claim to be compatible with readers in various formats. Although many reader formats have certain advantages in terms of locality, they do not conform to international standards and are upgraded in the future. Expansion and anti-jamming have brought troubles. We adhere to the principle of practical stability and conformity to the standards. It is recommended that you only need a reader that conforms to international standards. 90% of imported access controllers comply with this standard.
3, the more powerful the better the domestic many controllers to promote their products how much more powerful features, one-sided exaggerated function of the role of access control, in fact, for the access control stability and functional and practical operation is the most important. We propose to shield the powerful extension function, and customers need to provide it to meet their needs. Some functions that customers do not use should not be recommended to customers. This can reduce the cost and maintenance costs of training, and it can also be used by customers. .
4, the more expensive the better or the cheaper the better the price of the product is the best product. The expensive product may be because his output is not high, or the cost of advertising is too high, it does not necessarily mean that the value of the product is high. Cheaper products may also be the one-sided pursuit of low-cost, reduced investment in protection circuits, or the use of inferior and used chips. Therefore, the contractor must keep his eyes open to make a reasonable assessment of the product's performance and price ratio.
