Q: Who is to buy the access control system? To the factory agent or the engineering company?
A: Many consumers will have a misunderstanding. They feel that buying directly from manufacturers will result in cheaper prices and some after-sales services. In fact, it is not always true. Really powerful manufacturers generally do not develop and produce products, but also directly sell products to consumers. In particular, access control products are not a kind of daily necessities and require certain techniques for design, construction and maintenance. If manufacturers directly sell products to consumers, they will touch the interests of agents and contractors. Without the strong support and cooperation of agents and contractors, manufacturers have no broad prospects for development. Manufacturers' human resources are generally allocated to development and production and technical support sales. Generally, it will not be equipped with a large amount of manpower and resources for construction and on-site service. To some extent, the service level of agents and contractors in engineering will be higher than that of manufacturers. The price may not be lower than the prices of agents and contractors, because if the manufacturers do not want to mess up the price system, there will be no agents or contractors for the manufacturers. So, you often see that the price of a mobile phone store is higher than that of some vendors. That is the same reason. In addition, there is a benefit to buying from agents and contractors. If there is a problem with this agent or engineering company one day and you cannot continue to serve, you can still find the manufacturer and continue to provide services. This service has two protections. On the contrary, some small manufacturers, in order to benefit in the immediate future, buy products and do projects again, it is very dangerous to sacrifice the interests of agents and contractors to cooperate with you. He is very likely to do little, will be eliminated by the market competition. Therefore, I believe that consumers are best to purchase products from the manufacturers' appointed agents and contractors, but they can ask the manufacturers for technical issues.
Q: Is it an independent access control machine or a networked access control machine?
A: The so-called independent access control machine is not connected to the computer and set permissions, through the main card to pay for the card, or infrared remote control or password keyboard design registration card access permission. The advantages are: convenient wiring construction and low price. The disadvantage is that there is no personalized access rights management, there is no entry and exit records, only the basic functions of the access control. For a long time, the setting is complicated and tired. Less secure. The networked access control system manages the rights of all doors through a computer and sets powerful access control management functions and permissions. It can monitor the entrance and exit conditions of the doors in real time and query the entry and exit records of all doors. The more doors, the easier the setup and the more convenient the management. High security. The disadvantage is that the price is slightly higher than the stand-alone access control. Why is the independent type of access control less secure? Because the reading and control parts of the stand-alone access control are integrated, if they are installed outside the door, they will be opened for shorting and the door will open. Although an external card reader can be attached, the main body is installed in the door, and an external card reader is installed outside the door, so the cost is high. However, they can only guard against gentlemen and cannot prevent villains. If there is no way inside the thief. If the networked access control system can solve these problems perfectly. In addition, the networked access control system also has a basic attendance function, which can save the money for buying attendance and punching machines, and the attendance records are fair and objective, and the statistical speed is scientific and rapid. Therefore, if your company needs only a simple access control function due to cost considerations, it does not need a personalized access management function, and the number of gates to install the access control is not large, and the attendance function is not required, and the security requirements are not high. It is suitable for independent access control systems. If you want to use a real access control system, please choose a networked access control system. Moreover, the networked access control system has a good expansion, you can first take a few doors, feel good use, and then expand capacity.
Q: Do you need a liquid crystal display access control system?
Answer: The reader of the access control system is equipped with liquid crystals, which is not an advanced product identity. There are two advantages to using the LCD. One can display information such as the card number of the person who swipes the card, and the other shows how long it takes to swipe the card. However, the access control system is a durable product that requires long-term use, but LCD is not a durable product. Everyone knows that liquid crystal has a longevity, is relatively fragile, and cannot stand up to prolonged exposure to moisture and static electricity. The damage of the liquid crystal will also cause damage to the reader circuit at the same time, making the card reader malfunction and the person swiping the card into the door. Therefore, imported card readers, such as Motorola HID, do not have liquid crystal display. You may think that when I am attending, I know that the time is in line with the requirements of humanity. In fact, it will bring another bad side. For example, when your employee finds himself late when he punches the card, he quickly finds his leader and signs a special approval. . This loses the notarization of attendance. What is the use of unfair and unrealistic attendance results? Therefore, I believe that you want to ensure that the long-term security of the access control system is best not to fancy features to buy a card reader with LCD.
Q: How do users choose the type of card?
Answer: The types and formats of cards used by the access control system are: EM (ID Read Only) card, Mifareone (M1 Readable and Writable) card, and logic card TM card. Among them, EM cards and M1 cards account for almost 90% of non-contact cards. It is recommended that you use the EM card and M1 card as the access control system. Other cards that are not commonly used are not recommended because they have a small market share and may withdraw from the Chinese market. Then there will be problems with product upgrades and expansion. EM card features: cost-effective, the highest market share, long reading distance, the disadvantage is read-only, suitable for access control attendance parking systems, not suitable for non-fixed consumption systems. If you want to consider the consumption of a card, it is best to use M1 card. If only for access control attendance, EM card is the first choice. M1 card, the advantage is a readable and writable multi-function card, the disadvantage is: the price is expensive, sensing distance is short, suitable for non-fixed consumption system, not suitable for parking system. Applicable to access control attendance, no problem. There is a correspondence between the card type and the card reader type. Please note. If you have previously purchased a time and attendance system or a consumer system, it is best to continue to use the original card type, which is the lowest cost.
Q: Is "One Card" or "One Soft Pass" selected?
A: The so-called "one card" is the access control attendance consumption and even the parking lot all use the same card for management. Cards are registered and managed in different software systems. The so-called "one soft pass" is all the management functions such as access control attendance consumption and parking lot in the same software, and the card can be registered only once in the software.
The so-called "specialization in the medical industry" has made the company with good access control systems not necessarily do a good job of consumption, and the parking lot is doing well. By the same token, companies that do a good job in consumer spending may not be able to do a good job of control. Everything is done, and often nothing is done well. The card industry is still at the initial stage of development in China. There are no large-scale and mature companies, and all projects can be done the best. Some companies have seen the development prospects of "a soft pass + one card", some products do their own, some products are introduced through OEM OEM, and foreign declarations are all made by themselves. This model has some truth. However, if there is a problem with their cooperation model, or when quality problems and design problems arise in the products that are introduced, consumers cannot obtain sustainable after-sales services and quality assurance. There will be objective issues such as evading responsibility or failing to upgrade. Therefore, I still recommend that you purchase access control systems and software from professional access control manufacturers, purchase consumer machines and management software from consumer system manufacturers, and purchase parking facilities and software from professional manufacturers of parking systems. We promise to use the same format for sensing. card.
If your attendance is not complicated, you only need to purchase the access control software, because the general access control software comes with a simple and practical attendance function (normal shifts). If your attendance requirements are complex, such as factory attendance, which involves multiple shifts and three shifts across the night shift, it is recommended that you purchase the attendance machine separately from the attendance equipment company. Some attendance equipment manufacturers have added a relay to their attendance machines and claim to have access control functions. The author thinks it is inappropriate. Because of the functional requirements of the access control system and time and attendance system, the inspection standards of the products are not the same. The access control system focuses on product stability and safety convenience. Attendance system focuses on the powerful attendance function, and the stability and anti-interference requirements are not high, because if the attendance machine crashes or garbled you can easily reset the power. The access control system requires the system to work long hours without crashing. If the person is locked outside the door, it is impossible to perform a power-off reset. Frequent power-off resets will also add a lot of trouble to your use. In addition, the attendance machine integrates the control circuit in the attendance machine, and the attendance machine is externally installed outside the door. It is easy to open the door illegally through the short-circuit method, and the security is hidden.
Q: Is it the imported access control system or the domestic access control system?
A: I think we should buy better domestic products. Access control products have been introduced to China from abroad for 10 years, and China's own design capabilities and application experience have matured. Foreign products are more mature, but may not be suitable for China's national conditions and habits. Products may be stable but their advanced nature may not be as good as domestic products because the design of domestic products has a high starting point. For example, China’s securities trading system is more advanced than the securities trading system of the developed capitalist countries. This is the same reason. Imported products, because of tariffs, manpower costs and other reasons, are 4-10 times more expensive than domestically-made ones. There are many domestic products, invented an imported brand, trying to sell a good price, the packaging inspection report is done like a model, you can not do big, spend money, buy a not good product. Therefore, I suggest that you buy domestic products, the service will be better, the price will be cheaper. But the best products and companies have a history of more than 3 years, preferably the products of manufacturers with more than 5 years of history. why? Because the access control product has a characteristic, it is not difficult to do it, and it is difficult to do a good job. An undergraduate in an automation department can spend three months to make it, but this product is definitely not dare to use. I don't know if there will be a problem on some day. Why is it better to have a five-year history? Because five years ago, when it was done as a ban, products that were not doing well were almost eliminated by the market.
Q: Do you need to see the product test report before purchasing? Is the test report as good as possible?
A: The author thinks that the test report is still good. At least that the company still has a certain strength. I think that the ISO9001 certificate and the product quality supervision bureau report must have at least. In addition, the department's inspection report is also very authoritative. As for the 3C certification, there is no mandatory certification for the access control industry. Of course, do not blindly pass the test report to view the quality of a product. Because the inspection department is only responsible for the products that are sent for inspection, they are not responsible for the products they produce. Many test reports can solve the problem by spending money. We all know this very well. Do not superstitiously detect reports. Many bad manufacturers fake their own test reports by modifying the copies of others' reports. This point has a trick to identify, you go to the manufacturer's website to see the test report page, guilty manufacturers may not dare to clear the big picture out.
