Access Control System – Smart Cloud Access Control System

       The access control system, as its name implies, is a system that regulates the entrance and exit passages. 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.

       After more than 20 years of development, the access control system has gradually become a complete access management system, moving to everyday life and applying it to every corner, becoming the first line of defense and security, playing an important role. Nowadays, with the advent of new technologies such as 5G, artificial intelligence, Internet of Things, cloud computing, etc., under the development of new technologies, the access control system has continuously broken through homogenization and achieved new development.

I. Internet of Things technology

        The access control card system is a small part of the Internet of Things. The Internet of Things contains a wide range, which poses a great challenge to the access control card system. In the past, the access control card system was an independent system, relatively closed, around the card to open the door, attendance, consumption, patrol, elevator control, parking lot and other applications; now with the development of automation, the system needs to be linked with fire alarm, and CCTV Linkage, effective integration with BA system (building automation system), effective integration with information distribution system, etc.

Linked to fire alarm

        There are generally three ways to achieve this. First, the fire soft linkage is realized by OPC; secondly, the fire linkage controller in the access card product receives the fire information for linkage; thirdly, the fire linkage is realized by forcibly powering off the trip device.

Linkage system

        There are generally two ways of expression. First, the access control card device or the system itself supports the camera function, which can record and capture the scene; second, the access card device or system transmits the alarm signal to the linkage system for recording and capturing.

Effective combination with BA system (building automation system), interactive display

        The BA system generally monitors the temperature and humidity, and the access control card device is generally installed next to the door. The user can easily see the contact and see, then the temperature and humidity of the BA are transmitted to the LCD screen of the device, which is convenient to use. Know the current situation. The combination with the BA system is often done through a building automation protocol, and the Sedona protocol standard is more popular and convenient on the market.

Access control card system has information publishing function

       Many times information is released as an independent system. For example, the Focus Media that you see, hangs the TV on either side of the elevator or in the lobby of the building to play advertising information. The access control card system can also perform some functions of information release, such as displaying the weather conditions, welcome words and other information on the LCD screen of the card reader. At present, some devices on the market use touch screens. When some companies need to participate in the voting, we can use the function of the card device to let the participants swipe the card on the device, and then select the information to be voted on the touch screen to realize the function extension of the card system.

Second, artificial intelligence

       As an entrance and exit management system, the access control system is an important part of smart city and community construction, and the first level to ensure people's safety.

       At present, the access control industry has entered a saturated stage. With the new artificial intelligence technology enabling the security industry to provide an opportunity, the access control enterprises also understand that this stage of increment has been unable to provide market share and more profits for enterprises, and low-tech access control enterprises are Faced with the established ending of "elimination", in recent years, access control manufacturers have consciously detected the application of artificial intelligence technology in access control systems, actively embrace artificial intelligence, and accelerate the transformation and upgrading.

       At present, the widely used access control system works by brushing the access card. The residents need to carry the access card with them when entering and leaving the door. Once the card is lost, the subsequent compensation procedure is very cumbersome. Of course, fingerprint recognition also occupies a large part of the access control system. Compared with access control cards, fingerprint recognition is indeed a big improvement. However, when we encounter fingerprints that are broken, contaminated with water, dust, or even fingerprints, we may not be able to open the door because of contact.

       In the case of poor user experience in traditional access control systems, the face recognition access control system has become popular and has become a new choice for security management between buildings. Face recognition technology is a popular technology of artificial intelligence. It has the advantages of uniqueness, non-contact, non-mandatory, and concurrency. It is just right in the access control system. The face recognition access control system uses the facial features of the person to complete the identity verification, avoiding direct contact between the human body and the machine. Users registered through face information will automatically capture the real-time facial image and compare it with the background information as soon as they pass the system.

        Compared with traditional access control, the biometric access control system has the inherent advantages, greatly improving the effect of channel safety management, and also has the safety and convenience, eliminating the cumbersome manual retrieval. Today, as biometric costs decrease, more and more companies are trying to integrate biometrics into access control systems. Following the access control products such as face recognition and fingerprint recognition, technologies such as vein recognition and palmprint recognition have begun to be integrated into access control products.

        With the continuous evolution of artificial intelligence technologies such as biometrics, the combination of artificial intelligence technology and access control scenarios will become increasingly mature, and the application of artificial intelligence technology in the access control market will also exhibit more diversified development. The application of artificial intelligence technologies such as cloud storage, biometrics and intelligent sensing will further accelerate the pace of intelligent development of access control systems.
