Look at the three access control card reader matters

[ Huaqiang Security Network News ] The choice of access control card reader is also a very important link. The following small series introduces you to what we should pay attention to when choosing the access control card reader.
Access control card reader selection Note 1: Is the purchase of domestic card readers or imported card readers? The real imported card reader, the technology is relatively mature, the product has a low repair rate, and the design is more beautiful and durable. The disadvantages are: the price of the product is expensive, the service does not have a domestic card reader in time, and the imported induction card of the supporting brand must be used, and the imported induction card is also relatively expensive. Unless the customer specifies the use of an imported brand of card reader, I recommend the use of domestic card readers, but must choose a domestic card reader with good quality reputation and good service. The appearance of the domestic card reader has also made great progress in the past two years, and it has quickly caught up with the popular international style. Imported card readers are 6-10 times the price of domestic card readers, and imported card prices are 10-20 times that of domestic cards. The core chips of domestic card readers and cards are processed by foreign RF chips, and the development and production capacity of chips in this field are not available in China. Imported card readers recommend the use of model readers and card readers, which is relatively good value for money. Many domestic card readers casually affix a brand that does not exist in foreign countries, mark a country of origin, or have a fake certificate of origin. This kind of hanging sheep head buys a lot of dog meat, and the engineering company should pay attention. Don't spend money, don't buy good products, and get a lot of trouble.
Access control card reader selection Note 2: Is the ID card reader or IC card reader selected?
The ID card reader is a common name for a read-only non-contact IC card, and the IC card reader is a collective name for a readable and writable non-contact IC card. The performance price ratio and sensing distance of ID card and ID card reader are better than IC card and IC card reader. If it is only used for access control and attendance or parking card, it is recommended to use ID card reader and proximity card. If you need to be compatible with non-fixed spending cards, you can only use IC card readers and proximity cards. The ID card market is popular and the price is good is the EM card.
Access control card reader selection Note 3: Do not judge the quality of domestic card readers from the appearance alone?
Most domestic card readers use public molds or copy foreign readers. The mold is universal, and anyone can buy the outer casing, so even if the same type of card reader may be produced by different manufacturers, the service and quality are not the same. The engineer must have a detailed understanding of the card reader, not to distinguish it from the appearance and price. It is recommended that the contractor purchase the card reader from the place where the access controller is purchased. The general access controller manufacturer will either sell or produce a card reader with similar quality standards. So, how to judge the quality of a card reader? I believe that some domestic card readers use analog circuits instead of RF base station chips in pursuit of low cost of production. Such card readers have large operating currents, are prone to crashes or are damaged, Recommended. It is recommended that the card reader of the imported RF base station chip be better. Of course, it is also necessary to judge the use time and repair rate of the card reader of the manufacturer you purchased before, and the quality standard and word of mouth of the manufacturer. In addition, the card reader is a long-term use of the device, the circuit design must have a circuit to protect against the crash, this point should also be noted. Note 4: Is it a sealed or unsealed card reader? It is recommended to use a non-sealed card reader. The reason is: even if the glue is sealed, the buzzer is still exposed, and the water will damage the card reader. The material used for sealing is resin. Generally, the manual sealing agent is used to mix unevenly. The domestic resin material is cheap but the quality is not good. It will be conductive after long time use, which makes the card reader run chaotic or Dead machine, imported resin is expensive. Domestic manufacturers are generally reluctant to adopt it. It costs more than a dozen pieces for each card reader. In addition, the sealant is not suitable for heat dissipation of the device, and it also affects the performance of the card reader. Therefore, unless it is not necessary for special occasions, it is not necessary to use a sealed card reader. For some occasions, some waterproof protection of the card reader can be done.
