New technology and application of access control system (a)
Access control system after nearly 10 years of transformation and development, now, access control products in the functional development and market applications are already quite mature
At present, all access, manufacturers gradually turned to look, how to improve the additional value of the access control system, hope that through the access control system
The integration of system and other system to produce more functions, such as video recognition, electronic patrol, visitor services etc.. In this development trend
In access control system technology, the upgrading of the hot companies concerned, access control system in the future will also be a comprehensive control security platform. This paper
Inventory will be those hot access control technology for you.
Access control system technology to upgrade the unable to hold oneself back
From the traditional access control of the changing process, which can reflect the future trend.
First of all, the card reader technology firm in the continuous improvement. In view of the tape card will cause wear, can not touch technology
To avoid this problem. Due to wear the card material breakage and when in use, or need to update or re issuance, causing card service life
Life is limited. Along with the technique progress, the new pass will be the biometric, which solved the problem of life card. When the existing
Some of the old system and the limitations of water after removal, biological identification system function will rise. To make this change, biological identification
When in use must be integrated into the access control system.
Second access control is the development trend of distributed control function. In view of the lock and key is handing control to authorized persons. Once the system
The electronic, the control will also be from the central security control system through a simple card reader interface to "intelligent" control. This
The trend is further extended to control function into the card reader, and even into the card. Smart card access control industry of great significance
. They can store large amounts of data, readable can also be updated, can provide advanced encryption and password protection of stored data, but also
Through the calculation program with the ability to handle.
Access control system may have a new specification -- biological identification and access control permissions data stored in Cary and encryption, so that only
Local card reader can use this data. Biological identification will be used to interpret Cary's data and get permission. Card reader
Must be connected with the authorization database through a certain method, and according to the need to update the information on the Cary. Data communication is from scratch
Show up, such as mechanical locking system to cable system to use unique protocol, to use the standard communication protocol of network system. Data
With the development of communication, the device dependent connection cable of the smaller. Wireless communication has become more and more popular, the network service will become the future data
The cornerstone of library information dissemination system.
