Access control systems market and past life
With the rapid development of China's economy, people's security concerns prompted the rapid development of China's security industry market. Social security situation due to the economic development process also caused concern, the widening gap between rich and poor in developing countries so that the crime rate rising social demand for security products and therefore growing.
At present entrance system and monitoring,Anti-theft alarm,TalkbackSystem integration is the trend, and the boundaries of the four security systems are increasingly blurred, four security systems rely on computer software integration platform, including access control andPARKING LOTManagement System entrance system and intercom system integration is also the earliest start.
Past Access Control System
Access control systems and parking systems collectively known as access control systems, as the name suggests is to regulate the entrance channel system, where the release of some people, some people refuse to, when to sound the alarm memory access process, in order to control security purposes. It is based on the traditional door evolved. The traditional mechanical locks just a simple mechanical device, no matter how reasonable structure design, how strong material, it is always used by all means to open it. Management of large numbers of people out of a lot of trouble channel key, the key is lost or replaced together with personnel replacement is often put under lock and key.
To solve these problems, electronic card locks, electronic locks appear both lock up from a certain extent, people management level of the entrance channel, so channel management into the electronic age, but with the application of these two electronic locks their own shortcomings gradually exposed. A small amount of information stored in the magnetic stripe, contactlesscardversusCard ReaderRoom wear, high failure rate, magnetic lock problem is easy to copy information, low safety factor.
Life access control system
In recent years, along with proximity card technology,BiometricsThe development of technology, access control system has been rapid development, has entered a mature stage, there has been sensing card access control system, fingerprint access control systems, access control systems iris, finger vein recognition access control system, face recognition access control systems, access control disorder keyboard systems and other technical systems, they all have expertise in safety, convenience, ease of management and other aspects, applications access control system more widely. With the utilization of smart phones and other portable devices increase, the use of smart phones as an identification tool for access control systems also appeared.
Face recognition technology is popular in recent years, the industry concerned biometric technology, many manufacturers of video surveillance face recognition algorithm itself is writtenVideo cameraWhich, in order to enhance the image and value of intelligent cameras. Face recognition technology is widely used in the region feature analysis algorithm, which combines computer image processing technology and biostatistics in one principle, the use of computer image processing technology to extract feature points from the video portraits, using the principle of biostatistics for analysis mathematical model, namely facial feature template. Use has been built and tested face features template's face people like to characterize, based on the results of the analysis to give a similar value. This value can be determined by whether the same person.
Function access control system is also gradually increased, such as commonly used in college campusesCardSystem not only for access control, also commonly used in canteens, borrow books, dormitory management. Because things are adopting recognition technology, applications such recognition is growing.
