Four types of common access controllers to buy errors

The role of the access control system in the security management of enterprises is more and more important. The traditional mechanical lock management can no longer meet the security management of modern enterprises. Its performance is as follows:

• Improve security: Graded, time-zoned access rights management for designated areas, restricting personnel to randomly enter important areas, determining their access level and allowable passages based on their position and nature of work, and management of some important areas, such as Bank vaults and subway control rooms are equipped with a variety of access methods to meet regional requirements for better security and prevent theft.

• Improve management efficiency: Through the central management center, the status of each access point is known and set in real time, reducing the cost of personnel patrolling. The system can record events in real time, making it easy for companies to produce various personnel management reports such as attendance and schedules.

• Ability to integrate with other systems: Integrate a security platform that integrates with firefighting, alarm, and other systems to achieve accident warning and prevent various hazards. When the disaster enters the fire, the system can automatically open the gates set in the control area to facilitate the escape of people. In combination with the monitoring system, the access control system can automatically switch the photographic screen and monitor and record the parts that need to be monitored.

Access control system as an important part of the community security, the quality and performance of the core part of the controller, will directly affect the overall stability and security of the access control , so pay attention to common misunderstandings of the access controller .

Misunderstanding 1: Imported access controller will be better

The imported controller is very good in product stability and maturity. However, the price is expensive, and because of geographical disparity, the timeliness of the service will not be good, and the service cost will be high. At the same time, due to the differences in cultural background, the foreign users' needs and requirements for access control and management are different from China's national conditions. Many features are simply not suitable for China's national conditions and the needs of Chinese users. Of course, many Chinese access controller manufacturers have small production scales and weak design capabilities. There are few successful application cases, and engineering firms should also choose carefully. Many Chinese access controller manufacturers, in order to sell their own products, use fraudulent sales made in Taiwan, the United States, Canada, and other countries. In fact, product quality has great problems. This phenomenon should also be treated with caution.

Misunderstanding 2: The reader's compatibility is as wide as possible

Some controllers claim to be compatible with readers of various formats, such as the 485 format WIEC format readers such as wiegand3740. In fact, it is not necessary. Although these formats have certain advantages in local areas, they do not conform to international standards. In the future, upgrading and capacity expansion and anti-jamming have brought troubles. We adhere to the principle of practical stability and compliance with standards. It is recommended that you only need a card reader that complies with the international standards of wiegand26bit. 90% of the imported access controllers are in compliance. This standard.

Misunderstanding 3: The stronger the function, the better.

Many domestic controllers advertise how powerful their products are, and they exaggerate the function of the access control function. In fact, it is the most important for the stability of the access control and the simple and functional operation. We propose to shield the powerful extension function, and customers need to provide it to meet their needs. Some functions that customers do not use should not be recommended to customers. This can reduce the cost and maintenance costs of training, and it can also be used by customers. .

Misunderstanding 4: The more expensive the price the better or the cheaper the better.

A good, cost-effective product is the best product. The expensive product may be because his output is not high, or the cost of advertising is too high, it does not necessarily mean that the value of the product is high. Cheaper products may also be the one-sided pursuit of low-cost, reduced investment in protection circuits, or the use of inferior and used chips. Therefore, the contractor must keep his eyes open to make a reasonable assessment of the product's performance and price ratio.
