Nowadays, in order to meet the requirements of intelligent integrated design, integrated wiring and construction of engineering, and to save construction costs, the integration of various subsystems of security has become the current general trend. By integrating the subsystems together, the coordination of the entire system can be greatly improved, and the upgrade of the entire security system can be promoted.

Among them, access control is widely used and can be said to be the first pass of security protection. After nearly ten years of transformation and development, various access control manufacturers have gradually turned their attention to "how to improve the added value of access control systems", hoping to use the access control system to interact with others. The integration of the system produces more functions, such as video recognition, electronic patrol, visitor service and so on.

In this development trend, the application fields of access control systems are becoming wider and wider, and the technology development is gradually comprehensive. The linkage with intercom, monitoring and other systems also reflects the integration of security.

Access control and building intercom linkage

Access control and building intercom can be described as the "golden partner". Throughout the residential quarters, we can find that access control and building intercom are closely related and together form the first security checkpoint.

The linkage between the access control system and the intercom system belongs to the parallel linkage. This linkage method mainly integrates the access control system into the building intercom door machine to realize the function of swiping the card to enter the door. The correlation between the two is a pure hardware connection. And this linkage basically does not have any technical difficulties, as long as there is a reserved space in the intercom host to install the access control controller board, the "intercom access control" function can be fully realized.

In addition to the common real-time record and access record query function, the access control intercom installed in important places can also have other special functions, such as anti-tailing, network setting management monitoring, and fire linkage.

Access control and video surveillance linkage, one software to manage all

Video surveillance is the backbone of the security industry. In recent years, the total output value of global security equipment accounts for about 25% of the entire security industry, of which video security accounts for 54%, and access control systems account for 22.5%. Therefore, access control and video surveillance Linkage has become a hot spot for access control manufacturers. At the same time, the stability and integration of access control software is getting higher and higher, and the future access control system will be a comprehensive control security platform.

The use of an actively controlled access control system has changed the passive monitoring of security products in the past. The function of linkage with video surveillance requires that the management host of the access control system must be in the open state so that the real-time monitoring screen of the keypad controls software and the screen at each channel can be maintained Consistent.

The linkage between the access control system and the video system is not only limited to a control and confirmation phase of entrance and exit, but an effective security linkage structure is provided to enhance security and the ability of security personnel to handle emergency situations. For example, the access control keypad will send a signal to the video surveillance system to provide real-time recording of the scene of the event, which makes it possible to use the digital recording to trace back the picture before the event.

In addition, in addition to ensuring safety, it can also be applied to the attendance of enterprises and campuses, and the photos of employees in the database are used for verification to avoid the phenomenon of employees checking in on behalf of employees. It can also be used as a function of the student roll-call system in campus applications, To achieve the effect of "one machine at most multiple machines".

Access control and fire alarm linkage, Model No. is ACB-EA05,

here is the wiring diagram, as below:

The linkage of access control, building intercom, and video surveillance are for users to grasp security dynamic information in real-time, but as an access control system for entrance and exit control, in addition to monitoring and screening unsafe factors, it should also be able to give early warning and control of crisis situations.

Generally speaking, the fire alarm system is relatively independent and less integrated with other weak current systems. However, with the development of security technology, the integrated linkage of the fire alarm system and access control has become a development trend. The system can be integrated through TCP/IP software, or through the relay switch method to achieve the linkage effect.

When a fire alarm occurs, the corresponding access control system is dispatched through the security integrated platform to open the corresponding escape channel, and the elevator and escalator subsystems are suspended. At the same time, the video surveillance system is aimed at the alarm location and starts to record for evidence. When the alarm is lifted, the access control system closes the corresponding escape channel, turns on the elevator and escalator subsystems, and the video surveillance system resumes daily monitoring.

Conclusion

Whether it is a large smart city, a smart community, or a small smart home, or even a set of security equipment, integration and systemization will be the future development trend. Traditional isolated systems or equipment will be integrated by integrated platforms. replace.

As the "first guard" of security, S4A access control has the advantage of multi-party linkage. In order not to fall behind on the road of security integration, "improving the scalability and added value of the access control system" is the key to manufacturers.
