The first time I chose the access control system, how to identify the access control manufacturer?
If you are using or purchasing an access control product for the first time, the first choice is the access control manufacturer. The choice of the access control manufacturer is directly related to whether your access control system can be used normally? Can it be successfully accepted? Is there a lot of after-sales service? Can you get the most out of your economics? As the saying goes, "Men are afraid of entering the wrong line, women are afraid of marrying the wrong lang". In the access control industry, one should also add a sentence, "Engineering companies are afraid to choose a black heart."
If you "accidentally" choose a "black heart" access control manufacturer, this means that "nightmare" will always accompany you. However, what are the basic qualities and conditions that a good, regulated access control manufacturer should have: |
(1) ISO9001: ISO9001: 2000 international quality management system certification
(2) The technical quality of the CEO, it is best to be a technical background, master the access control technology, do not slip the oil, let alone eat and drink
(3) More than 6 R&D teams, at least one hardware engineer, one MCU engineer, two software engineers, one system tester and one R&D manager. It would be even better if there was a mechanical engineer with a shape design.
(4) There must be a full-time technical support team of more than three. Proficiency in the use of multimeters, oscilloscopes and other test tools, skilled in the company's products, with a certain access control theory.
(5) The quality of the sales staff. Pay attention to whether they are "exaggerated", do you often smash other manufacturers and raise yourself? Are you trying to help you with access control and system configuration? Is there a lot of promises for you but not enough technical guarantees?
(6) Production workshop. I suggest you take your time to look at their production workshop. Take a look at their process and inspection specifications. If they refuse you to look at their factory, beware that their products are also OEM. If you don't want to take risks, don't buy them. The production workshop should have production equipment such as placement machine, wave soldering, reflow soldering, etc. Does the worker wear an anti-static wrist strap when operating the circuit board? Does the test site have an oscilloscope? Does the product pass the 3-hour 50-degree high-temperature test and the 1-week power-on test at room temperature?
(7) If they have received the following honors, it is better, such as: high-tech enterprises, software companies, etc.
(8) Company trademark registration certificate. If there is no trademark registration certificate, it belongs to “three no products†and it is strongly recommended not to take risks.
What certificates should I get for qualified access control products ?
What certificates should I get for qualified access control products ?
(1) Providing ISO9001:2000 quality management system certification can ensure that products are in an effectively controlled state from research and development, raw material procurement, production, testing, packaging, transportation and after-sales service.
Enterprises that have not passed the ISO9001:2000 quality management system certification often cannot guarantee the consistency of the products. The samples are very good, but the mass production is not good; or some of the goods are good and bad.
(2) Providing the Ministry of Public Security inspection certificate Currently, some of the security products, such as security doors, safes, smoke detectors, etc., are mandatory by the state and require 3C certification before they can be sold and used. However, the state has not yet imposed mandatory regulations on access control products. Usually, in order to ensure product quality, it is necessary to pass the type test of the Ministry of Public Security. Similarly, products that have not been tested by the Ministry of Public Security may experience instability during the use process, or may affect the normal operation of other electronic products around.
(4) Providing the characteristics of product enterprise standard security products, each manufacturer's products have their own merits and are different. Therefore, in order to ensure product quality and facilitate engineering acceptance, in addition to the relevant national industry standards (GA/T 394-2002 entrance and exit control system technical requirements), it is usually necessary to develop the company's own product standards.
If the company does not have its own product standards, and there is a contradiction in the implementation of the contract, there is no uniform acceptance criteria. On the other hand, the quality of product manufacturing cannot be guaranteed.
(5) Providing a software copyright registration certificate can provide this certificate, indicating that the software has been tested by an authoritative department, and the intellectual property of the product belongs to the manufacturer, which can prove that the manufacturer has the necessary research and development capabilities and subsequent maintenance capabilities.
This certificate cannot be provided to indicate that the product was produced by someone else or that it has no basic research and development capabilities. Once the software has problems, or the customer requests to modify the software according to the actual situation, the manufacturer can not provide continuous services in this regard.
Which illusions will confuse your eyes ?

1) The world's smallest controller. It sounds a bit esoteric, but the actual use is not handy. First, the controller is too small, and the connection is inconvenient. Secondly, the smaller the controller, the smaller the terminal, the higher the accuracy, and the inconvenient and frequent plugging and unplugging; therefore, the size of the controller cannot be used as the product technology. The key to advanced assessment indicators depends on the stability, security and scalability of the product.
(2) Some fuzzy technical indicators advocated by the manufacturer. For example, the controller card has a capacity of 10,000 cards and can be expanded to 100,000 cards. If you encounter a similar situation, it is recommended that before the purchase, the manufacturer is first asked to demonstrate how to expand, whether these expansion capabilities are available, or whether the manufacturer will reserve it in the future but cannot provide it now. We are not talking about the poor extension function, but reminding the engineering company to distinguish between right and wrong before buying.
(3) There must be a degree of gorgeous samples, color pages, and boxes. Gorgeous samples, color pages and boxes can easily fool your eyes. Paying attention to the inherent product quality is the guarantee for the acceptance of your project as scheduled.
(4) High-end office buildings, but it is not allowed to visit the factory.
You are not allowed to visit the R&D center and the factory, or even tell you where the product is produced, or there is a ghost. Be especially worried.
