Four types of common access control controller purchase errors

　　Misunderstanding a: import access control controller will be better

　　The imported controller has good stability and maturity in the product.However, the price is expensive, and due to the geographical gap, the timeliness of the service will be poor, and the service cost is high.At the same time, due to the differences in cultural background, foreign users on access management control needs and requirements, and China's national conditions are different.Many functions are not suitable for China's national conditions and the needs of Chinese users.Of course, many access control controller manufacturers in China have small production scale, weak design ability and few successful application cases, so engineers should also choose carefully.Many Chinese manufacturers of access control controller, in order to promote their products, under the guise of Taiwan, the United States, Canada and other countries for deceptive sales, in fact, product quality has a big problem, this phenomenon should also be treated with caution.

　　Myth two: the more compatibility of the card reader, the better

　　Some controllers claim to be compatible with various formats of the card reader, such as 485 format ABA format WIEGAND 3740 format card reader, in fact, there is no need, although these formats in the local existence of some advantages, but does not meet international standards, for the future upgrade capacity expansion and anti-interference brought trouble,We adhere to the principle of practical stability in line with the standard is the best, we suggest you only need to meet the Wiegand 26bit international standard card reader, imported access control controller 90% is in line with this standard.

　　Myth 3: The more powerful the better

　　Many domestic controllers publicize how powerful the function of their products, and one-sidedly exaggerate the function of access control. In fact, it is the most important for the stability of access control and the practical function of simple operation.We suggest that powerful extended functions should be shielded and provided only when customers need to meet their needs. Some functions not used by customers should not be recommended for use by customers. In this way, the cost of training and maintenance can be reduced and the customers can feel satisfied with them.

　　Myth 4: The more expensive the better or the cheaper the better

　　The best products are the ones with good cost performance.Expensive products may be because their output is not high, or the cost of advertising is too high, but not necessarily because the product is of high value.Cheap products, it is also possible that manufacturers one-sided pursuit of low cost, reduce the input of protection circuit, or use inferior and second-hand chips.Therefore, engineering providers must sharpen their eyes to make a reasonable assessment of the performance and price of the product.
