Access controller to buy the four errors detailed explanation

Four access controllers to buy common mistakes

Misunderstanding 1: The imported access controller will be better.

The imported controller is very good in product stability and maturity. 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 project companies 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.

Misunderstanding 2: The reader's compatibility is as wide as possible

Some controllers claim to be compatible with readers of various formats, such as the 485 format WIEC format readers such as wiegand3740. In fact, it is not necessary. Although these formats have certain advantages in local areas, they do not conform to international standards. In the future, upgrading and expansion and anti-jamming have brought troubles. We adhere to the principle of practical stability and compliance with standards. It is recommended that you only need a card reader that complies with the international standards of wiegand26bit. 90% of the imported access controllers are in compliance. This standard.

Misunderstanding 3: The stronger the function, the better.

Many domestic controllers advertise how powerful their products are, and they exaggerate the function of access control functions. Actually, it is the most important for the stability of access control and the simple and functional operation. 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 customers can also use it freely. .

Misunderstanding 4: The more expensive the price the better or the cheaper the better.

A good, cost-effective 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.
