Q: From whom to buy the access control system? To manufacturers, agents or engineers?

A: Many consumers will have a misunderstanding, think that directly with the manufacturer to buy, the price will be cheaper, after-sales service will be guaranteed. Well, not really. Really strong manufacturers, generally do not have the development of production, and directly sell products to consumers. In particular, access control products are not a daily commodity and require certain technology to design, construction and maintenance.

If manufacturers sell products directly to consumers, it will touch the interests of agents and engineers, without the strong support and cooperation of agents and engineers, manufacturers do not have broad prospects for development. The human resources of the manufacturer are generally equipped with development, production and technical support. Generally, it is not equipped with a large number of manpower and material resources in engineering construction and door-to-door service. To some extent, the service level of agents and engineers in the project will be higher than that of manufacturers. In terms of price, it may not be lower than the price of agents and engineers, because if the manufacturer will make the price system disorderly, there will be no agents and engineers to promote the manufacturer's products. Therefore, you often see the price of mobile phone stores is higher than the price of some sellers, is the same reason.

In addition, there is another advantage of buying with agents and engineers, if one day this agent or engineering company has a problem and can not continue to service, you can also find the manufacturer and continue to provide services. In this way, the after-sales service has two guarantees. On the contrary, some small manufacturers, for the sake of immediate interests, and buy products, and do projects, sacrifice the interests of agents and engineers to cooperate with you, it is very dangerous. He may not be able to do well and will be eliminated by market competition. Therefore, the author believes that it is best for consumers to buy products from manufacturers designated agents and engineers, but they can consult manufacturers on technical issues.

Q: Is it necessary to buy an independent access control machine or a networked access control machine?

A: The so-called independent access control machine, is not to network with the computer and set permissions, through the main card or infrared remote control, password keyboard design registration card access permissions.

The advantage is that the wiring construction is convenient and the price is cheap.

The disadvantage is that there is no personalized access permission management, no access record query, and only the basic function of access control. Mendo, the setup is complex and tiring. The security is weak.

Network access control system is through the computer to all doors for permission management, set powerful access control management functions and permissions, you can monitor the door access in real time, query the entry and exit records of all doors, the more doors, the easier the setting, the more convenient the management. High security. The disadvantage is that the price is slightly higher than the independent access control machine.

Why is the security of independent access control machine low? Because the reading card and control part of the independent access control machine are integrated together, if installed outside the door, it will be opened for short connection, and the door will be opened. Although it is possible to attach an external card reader and install the main body inside the door, the external card reader is installed outside the door, so the cost is high. But still can only guard against gentlemen, can not guard against villains. Not if it's an inside job. If the networked access control system can perfectly solve these problems. In addition, the networked access control system also has the basic attendance function, which can save the money to buy the attendance card machine, and the attendance record is more fair and objective, and the statistical speed is scientific and fast. Therefore, if your company for cost considerations, only need a simple access control function, no need for personalized access management function, and the number of access control doors to install is not large, and does not need attendance function, security requirements are not high, it is suitable for the use of independent access control system. If you want to use a real access control system, please choose a networked access control system. Moreover, the networked access control system has better expansion, you can first on a few doors, feel that it is easy to use, and then expand.

Q: How do users choose the type of card?

Answer: The most used card types and formats of the access control system are: EM (ID read-only) card, Mifare one (referred to as M1 readable and writable) card, logic card TM card and so on. EM cards and M1 cards almost occupy more than 90% of the market share of contactless cards. It is recommended that you choose EM card and M1 card as the access control system. Other cards are not commonly used, do not recommend you to use, because their market share is small, may withdraw from the Chinese market, then there will be problems in the future product upgrade and expansion.

The characteristics of EM card are: good cost performance, the highest market share, long card reading distance, the disadvantage is read-only, suitable for access control, attendance, parking and other systems, not suitable for non-quota consumption system. If you want to consider the consumption of the card, it is better to use the M1 card. If it is only used for access control, EM card is the first choice.

M1 card, the advantage is a multi-function card that can be read and written, the disadvantage is: the price is expensive, the induction distance is short, suitable for non-quota consumption system, not suitable for parking lot system. Applicable to access control attendance, no problem. Note that the card type corresponds to the card reader type. If you have previously purchased an attendance system or a spending system, it is best to continue with the same card type, which has the lowest fees.

Q: Do you choose "One card" or "One Softpass"?

A: The so-called "one card" means that access control and attendance consumption and even parking lots are managed with the same card, and the card is registered and managed in different software systems. The so-called "One soft pass" is the same software for access control, attendance consumption and parking and other management functions, the card only needs to be registered in the software once.

The so-called "professional specialize", do the access control system to do a good company, not necessarily do a good job, the parking lot is also done well. In the same way, a company that does a good job in consumer machines may not necessarily do a good job in access control. Do everything, often do nothing well. The card industry is still in the initial stage of development in China, and there is no large mature enterprise that can do the best in all projects. Some companies, seeing the development prospects of "one softpass + one card", some products are done by themselves, some products are introduced through OEM labeling, and they claim to be done by themselves. This pattern makes some sense. However, once there is a problem with their cooperation model, or the quality problems and design problems of the introduced products, consumers cannot obtain sustainable after-sales service and quality assurance, and objective problems such as shirking responsibility or unable to continue to upgrade will occur.

Therefore, I still recommend that you buy access control system and software from professional access control manufacturers, purchase consumer machines and management software from consumer system manufacturers, and purchase parking equipment and software from professional manufacturers of parking lot systems, and we agree to use the same format of induction cards. If your attendance is not complicated, you only need to buy access control software, because the general access control software is attached with a simple and practical attendance function (normal shift). If your attendance requirements are complex, such as factory attendance, involving multiple shifts across three shifts at night, etc., it is recommended that you purchase a separate attendance machine. The access control system focuses on the stability and safety of the product. Attendance system focuses on the powerful attendance function, the stability and anti-interference requirements are not high, because if the attendance machine crashes or garbled code you are easy to power reset. The access control system requires the system to work for a long time without crashing. If people are shut outside the door, it is impossible to carry out power reset, and frequent power reset 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 placed outside the door, it is easy to illegally open the door through the short-circuit method, and there are hidden dangers in security.

Q: Do you want to buy imported access control system or domestic access control system?

A: I think we should buy the best 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 of use, the product is stable but advanced may not be as good as domestic products, because the design of domestic products is high. For example, it is the same reason that China's stock exchange system is more advanced than that of developed capitalist countries. Imported products because of tariffs, production costs, labor costs and other reasons, the price is 4-10 times that of domestic access control, the cost performance is not good. There are many domestic products, make up an imported brand, trying to sell a good price, certificate of origin, packaging, inspection reports are done like a model, you can not be a fool, spend money, buy a not good product.

Therefore, the author suggests that you buy domestic products, the service will be better, the price will be cheaper. But the best products and companies have more than 3 years of history, preferably more than 5 years of history of the manufacturer's products. Why is that? Because access control this product has a feature, it is not difficult to make, do a good job of stability is difficult, an automation department of college students can spend 3 months to make, but this product is certainly not dare to use. I don't know which day there will be a problem, why is it best to have 5 years of history, because 5 years ago to do access control, products do not do well, are almost eliminated by the market.

Q: Do I need to see the product test report before buying?

A: The author believes that the test report is still good. At least it shows that the company still has some strength. The report of the quality supervision bureau of the product should at least have, as for the 3C certification, there is no mandatory certification for the access control industry. Of course, do not blindly look at the quality of a product through the test report. Because the testing department is only responsible for the products sent for inspection, they are not responsible for the products produced, and many test reports can be solved by spending money, which we all know. Do not be superstitious about test reports, many bad manufacturers, by modifying the copy of others' reports, to forge their own test reports. There is a trick to identify this, you go to the website of the manufacturer to see the page of the test report, the guilty manufacturer may not dare to put a clear picture out.
