Security Integrated Platform Technology Foundation

Systems currently widely used in the security industry include the following broad categories:

• Video surveillance subsystem;

• Alarm protection subsystem;

• Access Control Patrol System;

• voice intercom subsystem;

• Audio-visual broadcasting subsystem;

• Intelligent Analysis Subsystem;

• perimeter protection subsystem;

• Positioning tracking subsystem;

• Power environment monitoring subsystem.

For the above different types of security subsystems, the integration technology is diversified. Divided from the integrated communication technology, it can be divided into two categories: local integration and network integration. Typical examples of local integration are: Monitoring the LED screen of the command center. When the bank monitoring center receives a networked alarm signal, alarm information such as the location and type of the alarm and the contact information of the responsible person is displayed on the LED screen, which can greatly improve the police situation. Processing speed. Because geographically close to the platform server, and LED screen controller devices mostly use serial communication; network integration is mostly using the mainstream TCP / IP communication protocol for communication, with no geographical restrictions, low transmission costs and other advantages, the most widely used Such as: alarm, access control, voice intercom and other systems are widely used network integration.

Divided from the integrated technology used, it can be divided into three categories: device protocols, SDK interfaces, and database integration.

The device agreement can be further subdivided into proprietary proprietary protocols and industry standard protocols. In the field of video surveillance, the industry standard protocol represented by ONVIF has gradually been accepted by the market. Whether the platform is compatible with the standard protocol is an important indicator of the openness of the platform. The use of public protocols can also avoid the problem of compatibility between the platform and the manufacturer. From the user's point of view, it is generally expected that industry-standard agreements can be adopted. In the fields of alarm, access control, intercom, etc., there is no industry norm. This is an objective reason. Because these systems do not require large-scale networking after the project was completed in the early stages of the project, they are building a complete system independently based on the customer's organizational unit. In this case, the integration platform can only be networked through private protocols. With the increasing importance of networking platforms, when the market appears influential platform manufacturers, the platform manufacturers to determine the agreement or interface will become another trend, which will be explained below.

When the device protocol is very complex and contains a lot of content and communication data, in order to reduce the complexity of programming development of the integrated platform, the manufacturer has once packaged the protocol to form the SDK. At the same time, another benefit is that the developer does not Then you need to care about any device details. You only need to call the SDK interface to complete the corresponding function.

The third type of database integration is another form of integrated platform technology that applies to those who only need to obtain system state, data integration, typical access control system integration. The integrated content of the access control system removes users, rights allocation, etc., 90% of the daily time only needs to pay attention to open-door linkage video pop-up, door open warning, open-door record query and other status information. And many network access control systems can only support single connection. The platform is the best way to integrate information through database integration.
