Access control system to create a "security integrated system"

[ Huaqiang Security Network News ] With the development of society, access control products can be seen everywhere, and at the same time, the technology has also improved a lot. How can the access control system realize the security integration system? Alarm and Event Information Management <br> The integrated security integrated system based on the access control system mainly includes two parts: the front controller and the management platform.
The way to integrate on the basis of the access control system is that the main functions served by the overall system are biased towards access control and portal management. “When an event occurs, it must be detected by the alarm front-end system first. When the alarm information is transmitted back to the management center, it can be viewed in real time by calling the video image. However, in this series of reactions, the alarm system is only An early warning mechanism, while the video system implements a review and review, only the access control system can truly achieve control of the site conditions.
Of course, once an event occurs, all alarm events (access, alarm, patrol, etc.) of the system can be linked to the hard disk recording system of the TV monitoring system and the matrix controller to respond accordingly. For example, when a door in the access control system is illegally opened, the integrated system controls the matrix controller of the television monitoring system to switch the camera image corresponding to the gate to the main screen of the television monitoring system display and the management platform of the integrated system, and Start the DVR for recording. If the camera has a PTZ, you can also control the PTZ to rotate to the preset position on the management platform.
At the same time, the system also has the function of triggering the execution of the script program by the alarm event, so that some alarm events can be associated with the control of the DVR according to the needs of the user. For example, when an alarm event starts, the DVR is triggered to start recording, and the remote control of the DVR is executed. The program can also query and retrieve video information as required.
In addition, the alarm event record of the access control system can be used to view the live video recording at that time. The matrix control module of the system can also directly control the decoder of the selected camera, and usually has built-in control protocols of matrix controllers such as PELCO, PHILIPS, and PANASONIC. Achieve control over other brand matrices.
Integration with other software <br> For security system integration, it is not only the integration of hardware, but also other software (such as: fire alarm, building automation, information release, elevator control, consumer systems, Integration, etc.) Integration, its integration depends on the degree of openness of the various hardware devices, that is, whether these hardware devices provide interfaces and protocols.
Only the hardware provides a unified interface (SDK or API function), the software can manage and control the hardware through the interface, and always master the working state of the hardware. Of course, the software should also provide a linkage strategy and a plan mechanism. At the same time, the software integration of the system should also support hierarchical management. For example, software integration in the rail transit system includes software integration of the operation management center and software integration at the station level.
However, different hardware provides different interfaces, which requires us to modularize the software, and we use a module to manage it for each type of hardware. Because of the different projects, the front-end equipment used is not exactly the same. It is impossible to pick up a project, it is necessary to develop or purchase a set of software. Just like WINDOWS is an operating system platform software, no matter what hardware configuration of your PC, you can install it, because different hardware, there are corresponding drivers for WINDOWS. To change an accessory, just reinstall the corresponding driver. Therefore, the security integration software will gradually realize the 'platform' and 'module'.
The interface provided by the hardware should provide functions such as state access, device operation, system configuration, etc., and manage various hardwares and implement hardware functions through the TCP/IP protocol to achieve system integration. However, at present, in the Chinese security market, because many manufacturers are unwilling to disclose their products in order to guarantee their market share, the compatibility between brands is poor, and the integration level is still relatively low.
Understanding End-User Needs <br> In addition to understanding the key technologies of integration, integrators and contractors need to really understand the actual needs of end users.
Because many end users are blindly pursuing multiple integration functions, but lack understanding of system integration, it often causes a waste of system functions. For example, many building developers pay too much attention to the appearance and price of the system. They often only pay attention to the local effect, and do not consider whether the whole system is reasonable. It can be said that the technology is often overlooked for economic benefits. In addition, some developers believe that branding is a good project, and some users simply do not combine their actual needs, blindly pursue the powerful and complex system functions, and think that the bigger the system, the better. In fact, such integrated systems are often used in the process because they are either not practical or used, or they are put aside because the functions are too complicated.
Therefore, for the end user, when doing system planning, you should first understand what your actual needs and system integration are. For example, what subsystems need to be integrated in the engineering project? If it is an access control system, what level of integration should be achieved, how to link with other systems (alarm system, access control system), etc., all need to be with the engineering company or The integrator communicates to avoid deviations between their own needs and the effects of the integration.
In addition, according to industry insiders, the demand for China's security integration market is currently experiencing a period of incitement. Since many system integrators are transformed by engineering companies or network operators, the level of technology of each integrator is also uneven. Most of the builders of system integration do not have their own technical strength, and the overall planning and potential of the system. The function mining is not enough, the system can not be optimized, and it is limited to installation and debugging; in addition, integrators in order to expand their own business, fully cater to some unreasonable needs of customers, making "system integration" seriously misrepresented or misunderstood.
Therefore, whether it is security vendors, system integrators, or engineering companies involved in system integration projects, they need to continuously strengthen their understanding and understanding of system integration, improve the level of integration technology, in order to choose a more suitable platform for customers, to achieve The effect that the customer expects to achieve.
Prospects <br> With the increase in security requirements, the definition of security systems is gradually developing. Single access control and alarms can not meet the needs of modern security management and control, CCTV, patrol, parking lot management, consumption, The addition of subsystems such as attendance and elevators has gradually improved the security system. However, the increase in subsystems also means an increase in the management platform, while the complexity of management will increase, and the ability of the security system may be weakened. Therefore, only the rational and scientific integration of these systems into a unified platform is the best way to solve this problem.
As mentioned above, access control and alarming are already a mature system. The foundation of all integrations is usually developed based on the integrated management platform of access control and alarm. For the patrol and parking attendance, the same card reading device can be used to collect data. So that data can be unified. Consumer systems, because of their sensitivity to money, usually use a separate database.
Of course, the access control system is also a mature system. Because of the difference between its data and other systems and the requirements of the management platform, the integration with it is usually the linkage integration, which not only ensures the independence of the system, but also guarantees the independence of the system. The entire security system is interrelated, thus fully exerting the functions of each subsystem.
