Campus security subsystem is expected to achieve linkage

The construction of Ping An China is required to be promoted to a "higher starting point and higher level." The college security market, which has been slow to develop due to factors such as tight funding and lack of attention from leaders, is expected to usher in a rare opportunity for development. With the improvement of social security requirements, the development of university security has ushered in new development and the integration of subsystems is imperative.

New requirements: High-definition, integration, and smart look at the construction of domestic university security systems. Video surveillance, intrusion alarms, emergency alarms, electronic patrol management, access control management, parking lot management, and intercom systems are still the focus of construction content. However, when it comes to specific needs, some new trends can be found.

The first is the demand for high-definition video. The highest resolution of the original analog camera video can only reach D1 (720×576), which cannot effectively distinguish the target details and fail to achieve the purpose of forensics. At present, the mainstream network camera image resolution can reach at least 720P (1280×720) or even 1080P (1920×1080). The resolution is several times that of the analog camera, and the image evidence can be clearly obtained.

Followed by the need for integrated management of various subsystems. Through an integrated management platform, the video surveillance system, alarm system, access control system, parking system, and command and dispatch system are integrated and managed on a single user interface to form linkages between subsystems, facilitating emergency response and greatly improving security. The efficiency of work.

The third is the demand for intelligent video analysis systems. Through the cooperation of the front-end camera and the back-end platform, set up detection plans such as cross-border, people statistics, crowd gathering, legacy detection, video quality diagnosis, etc., and when they are triggered, notify the on-duty personnel in the form of an alarm event and be able to respond to emergencies in a timely manner. .

New Generation: Cloud Computing With the maturity of network technology and the reduction of storage costs, digital monitoring systems (including high-definition network monitoring and HD-SDI technology) will occupy an important position in the university security market. At the same time, an intelligent analysis system based on high-definition video will bring a lot of convenience to college security work.

Moreover, the security system will have a large amount of video data every day. Over time, it will form massive amounts of video data. The introduction of cloud computing is a matter of course. It performs complex image analysis algorithms on these mass data, thereby extracting useful information, such as faces, license plates, behaviors, and related interception of screenshots and video clips, significantly improving security and prevention capabilities. Management efficiency.

The problem of integration of old and new systems In the process of university expansion or reconstruction, apart from paying attention to the new demands put forward by the security department, it is also necessary to focus on the application of the integration of new and old systems. Newly built university security systems mostly use digital management platforms. Therefore, as long as it is an analog monitoring device with a digital standard interface, it can be accessed via the SDK. The current common practice is to use an embedded hard disk recorder to access the digital management system through the SDK. Other security devices, such as the alarm control host and access controller, can also access the new management platform through the network interface or serial port.

How to integrate the subsystem?

As mentioned earlier, the school’s demand for integrated management of various subsystems is heating up. In this regard, personally think that video surveillance and alarm systems (including intrusion alarms, emergency alarms, and fire alarms) are the most integrated and necessary for linkage. When an alarm event occurs, the associated image can be switched to the specified position in time for display. The guards are able to verify the situation of the field and plan handling at the first time. At the same time, an alarm recording label is generated to facilitate post-mortem verification.

Although the access control system can also be linked with the video surveillance system, it is not necessary in day-to-day security management.

Since the card system involves financial transactions, it is not the same as the security level and management department of the access control system, so there is no need to force the two systems into a single piece. However, the personnel data of the access control system can be obtained through the database of the card system.

Subsystems are expected to achieve linkage. Currently, the integration of subsystems in Chinese universities is rarely linked, and they do not achieve a high degree of integration of the unified management platform. This is a shortcoming for campus security and how to effectively implement security subsystems. High-efficiency integration has become a top priority for security companies to establish a safe campus. Due to obstacles in security technology limitations, platform compatibility and other factors, the deep integration of China's university security systems is still blank, and the integrated development trend of the security industry will also encourage more companies to participate in the development of integrated platform software. The integration of security systems will no longer be out of reach.

Many colleges and universities in our country have achieved the integration of the access control system and the campus card system to achieve a multi-purpose card, and some can also be linked with the monitoring system. Any person who passes the access control will be captured by the monitoring system; the perimeter protection system is mostly infrared. Curtains, etc., should be linked to the monitoring system. Schools, laboratories, archives, financial offices, and office buildings, etc., in schools can be deployed with small perimeters, intrusion alarm systems, entrance and exit control systems, and video surveillance systems. It is used to prevent illegal infringements and can also be armed through intelligent analysis. The alarm system is connected with the front camera to complete the linkage with the monitoring system. Because the campus of the university is relatively large, in order to facilitate the teachers and students in the event of an accident to be able to alarm in time, an emergency call for help point should be set up in the key area to facilitate timely contact with the monitoring center. .

In addition, the campus video surveillance system and entrance and exit control system should also be linked with the fire alarm system and emergency broadcast system. In the event of an accident such as a fire, an alarm can be promptly issued. The emergency broadcast system commander can quickly withdraw and pass through the entrance and exit control system. Statistics on the personnel at the scene. The security application can be combined with Internet technology and multi-functional control equipment and will enter the daily campus management business.

For school violence incidents in primary and secondary schools and kindergartens, the school’s video surveillance and emergency alert systems should be networked with the 110 Command Center video system. In particular, fastball cameras installed near the school gate should cover more than 25 meters on both sides of the school entrance. Install an emergency alarm button that can be linked with the monitoring system near the entrance. Once an emergency occurs, all levels of personnel can use the emergency button to activate the linkage camera to automatically adjust the angle to monitor and record the alarm area. Through the Internet, the police will be uploaded to the 110 command center, and the images will be automatically switched to the scene so that the police can quickly and effectively take effective measures to stop the incidents of campus violence, so that the campus is within the scope of police safety monitoring, so that the safety of the campus An effective police force guarantees that this is extremely important for preventing school violence in primary and secondary schools and kindergartens.

In addition to the linkage and integration of video surveillance, burglar alarms, and access control cards, multimedia teaching and electronic proctoring systems will also be integrated into large platforms. The integration of subsystems in the security system is the focus of the university. At present, the integration of university security systems is mainly the integration of video surveillance, burglar alarms, access control and fire protection systems. After the subsystems of campus security are linked, if an accident occurs on the campus, the corresponding system will issue an alarm and cause the relevant personnel to pay attention to achieve the purpose of pre-prevention.
