Automatic door operator

Most people believe that access is only for the entry-control devices, the most typical installation of the door is a traditional keyboard controller or magnetic card reader, right out in order to obtain access must swipe. Now, however, have more advanced access control technologies and new applications market, and now the technology used in access control systems: bar code, graphic ID, magnetic bar code, Wiegand, inductive, smart code, biometrics, etc. Including induction and biometric swing door motors access control access control access control will be the development of two major trends.

The technology used in access control system and can achieve the security level of each other. For example: Optical technology for bar code and graphics ID system to identify bar codes and graphics stored in the ID information; electromagnetic technology is applied to the magnetic card access control system, when the magnetic brush holder, the system will be allowed to enter the magnetic read Features: Wiegand technology is extremely clever, still areas of electromagnetic induction techniques commonly used frequency is usually in the 110-125kHz, the frequency is stronger, inductive card reader access control system the greater the distance, as technology continues to improve, the frequency of 13.56MHz induction card reader access control system has some distance to reach Im, the access control system has many other applications, such as: parking, fees and charges system. Of course, the most secure access control system should be able to identify human biological characteristics, rather than identify the object held by the characteristics of the system, such as: the use of human biological characteristics unique biometric fingerprint identification system and the structure of the pupil, it will be access control systems highest level, but the price is extremely expensive, difficult for the majority of user acceptance.

In contrast, the Automatic door openers technology is more mature and complete, is still more reasonable price-sensitive access control system, many experts predict that by 2012 induction ceremony will replace other access control system access control (such as: access control systems electromagnetic, etc.) to become the dominant access control market. Proximity access control system is able to quickly accepted by the market for several reasons:

Simple to use;

Because the system without any mechanical wear and tear, so the long-term maintenance costs low;

Cards and long service life.

Preparation of an edge access control system, the following description of several systems.

The traditional magnetic card access control system in a small area there is still a market, the access control system and the introduction of new access control system, compared to its low price has become an absolute market advantage, especially now that most users can afford only small access the system. People often think that the connection process in the use of magnetic cards have easily copied, easily degaussing and other issues, security is not enough.

In order to meet the needs of users at all levels, the market has emerged a small electric barriers access control system technology. This card reader system takes only a few readers and a separate controller for only 1 or 2 entry application areas, such small devices or alarm systems usually used in conjunction with electronic locks. In this way, a number of retail stores or small shops can use this small-scale systems management. The small access control system to make it an increasingly wide range of applications, there are several small access control systems access control system is optional.

The emergence of a compatible card card can be used in a variety of different power door opener access control system, allowing the user to a multi-purpose card. Because of this card reader for all: Graphic ID. Induction, bar code, magnetic card accepted, so cardholders can access a card to complete a variety of different buildings or different functions. The flexibility of this card become a powerful competitive weapon.
