What kinds of common access control systems?
As the name implies, the access control system is a system for regulating the entrance and exit channels. It is developed on the basis of traditional door locks. Common access control systems include: password recognition access control system, credit card recognition access control system, biometric access control system and so on.
Password recognition access control system
The access rights are identified by verifying that the entered password is correct. These products are divided into two categories, one is the ordinary type, the other is the out-of-order keyboard type (the number on the keyboard is not fixed, and it changes automatically from time to time). The advantage of password recognition is that it is easy to operate, no need to carry cards, and the cost is low. The disadvantage is that the security is poor and easy to leak, only one-way control, no door opening record, the button is easy to damage, failure.
Swipe identification access control system
According to the type of card, it can be divided into contact card access control system (magnetic stripe card, barcode card) and contactless card (also called proximity card, radio frequency card) access control system. The contact type products are easy to wear due to the contact and the card is easy to be copied, and is easily broken by the external magnetic field, and the use scene is small, and is generally used only in the case of a bank card (magnetic stripe card). The contactless card has the advantages of convenient use, strong durability, fast reading speed, and high safety.
Biometric access control system
In and out is identified by examining the biometrics of the person. There are fingerprint type, palm shape, iris type, face recognition type, finger vein type and so on. Its advantage is that it will not be lost, will not be stolen, no memory password burden, safe and convenient. However, the stability and accuracy of biometric identification are still further improved, and the price of products is also higher than the previous two categories. The applicable scenarios also have certain limitations.
New access control system
In recent years, new forms of access control systems such as QR code, Bluetooth, and WIFI have emerged. After the households verify their identity through the mobile APP, they can use the mobile APP to open the door near the access control machine. At the same time, the resident can also generate a QR code image that authorizes the visitor to open the door and share it with the visitor. The visitor's QR code has time and number of opening times. .
After more than 20 years of development, the access control system has gradually become a complete access management system. With the continuous development of the security industry, traditional password recognition and card recognition have been difficult to meet market demand. The development and rise of Internet of Things, cloud computing and smart mobile devices have prompted enterprises to develop new products and technologies to gain greater market space. And product profit margins.
