Access control industry development status

In the first half of the development of the intercom industry, the intercom industry witnessed a half-yearly progress. In the past six months, the security issue has been ups and downs, and the security industry has faced this huge challenge. As one of the security industry subsystems access control intercom system, card, access control identification, smart locks, etc., there is technology to make up for, there are loopholes in the lack of regret, can be described as sad and happy.

Building Talkback: The digitalized hot-spot building intercom system will be the basic configuration of the intelligent building community. In the newly-built commercial housing design, some cities have been forced to implement. Building intercom system from ordinary intercom, to black and white video intercom, color video intercom, features more diversified. Such as the door machine to introduce image recognition technology, fingerprint identification technology to make the system more humane; using audio and video digital technology, ARM embedded technology allows the system to directly access the broadband network, using Bluetooth technology can achieve wiring-free wireless building intercom systems, etc. .

With the development of the real estate industry, the full digitalization of benchmarking projects, digital building intercoms are hot, building intercom companies have linked digital, network and building intercom, and TCP/IP intercom technology has gradually matured. On the market, its highly efficient and convenient features make digital and TCP/IP technologies quickly recognized by the market. Traditional analog intercom systems, when the size of the community is too large, or have more floors, will inevitably appear due to the distance of video transmission. The problem of signal blurring caused by too long distances; at the same time, there are congenital weaknesses in multi-channel problems, which are difficult to overcome. The use of digital technology can solve these two problems well. That is, the networking part uses the standard TCP/IP protocol to transmit compressed-encoded audio and video digital signals. Since video, audio, and control information are all digital signals, there is basically no signal attenuation problem and it is easy to meet long-distance transmission requirements. In addition, the networked physical network uses a standard Ethernet architecture and network sharing to easily meet the requirements of multiple channels.

One card: The most fundamental requirement for information sharing and centralized control of card systems is "information sharing and centralized control." Therefore, system design should not be a simple combination of individual functions, from a unified network platform, a unified database, a unified identity authentication system, Data transmission security, various types of management system interfaces, exception handling and other software design considerations of the technical realization of thinking, so that the management system, the card reader terminal equipment, the overall performance of intelligent to achieve the best system design.

The "one card" card must be a multi-partition, check with the partition password, and a smart card with versatility, compatibility, security, and reliability. This is a prerequisite for "one card." Read-only or non-writable, non-regional, non-security, and useless cards cannot be "one card."

"One card" as an inevitable trend in the field of smart card development, is a complex and demanding system application engineering, its hardware and software must meet certain conditions and standards, otherwise it is difficult to achieve a true "one card." Combining all the functions needed in daily life on one card requires all the partitions that contain these functions and a huge unified network platform, a unified database, and a unified identity authentication system. So this road is still very long.

Wireless access control system: no wiring, reliable, energy-saving access control system is accompanied by a large number of wiring from the first day of birth, a complete access control system consists of card reader, controller, electric lock, exit switch, magnetic door, power supply, The management center consists of eight modules, each of which requires an online connection. At the same time, the front and back of the door frame and the top and the top of the door must be perforated to install the equipment. Therefore, the construction is cumbersome and very intuitive.

The wireless IoT access control simplifies the door point device to the extreme: a battery-powered lock. In addition to opening the door to lock the door above, there is no need to install any auxiliary equipment around the door. The entire system is concise and clear, significantly shortening the construction period, and can also greatly reduce the cost of post-maintenance.

Frequency hopping and encryption are another core of wireless access control. One big difference between wireless and wired is that the wireless signal is transmitted in the air, so it is very easy to be disturbed by the outside world and it is also easily captured by the outside world. Therefore, security and reliability can be said to be the lifeline of wireless access control products.
