School safety work directly relates to whether young students can grow safely and healthily, and it is related to the happiness and social stability of thousands of families. Campus shooting in the United States has sounded the alarm for the global campus security field. Campus security has become the focus of everyone's concern. Local governments have also invested heavily in the construction of campus security.

Campus security is a piece of land that is not yet cultivated. At present, security in most schools is in a blank state, which is a fertile ground for the security market to be opened up. According to the different conditions of the schools and the economic conditions and scale of each school, the investment in security projects is not the same. In general, the amount of investment required for kindergarten security projects ranges from 50,000 to 200,000, primary and secondary schools are 10-50 million, and colleges and universities have 200-500 million. Take colleges and universities as an example. If the campus covers an area of ​​3,000-4,000 mu, there are 10,000 students and faculty members. There are generally two universities with more than two campuses. There are about 200 monitoring sites, and there are 30 anti-theft alarm network centers. 60 users. Like this comprehensive type of security project for colleges and universities, the amount of investment required for security systems is approximately 4 million. Nearly 2,000 colleges and universities in the country, in order to roughly calculate that the security system of ordinary colleges and universities will have a market size of about 7 billion yuan.

According to industry analysts, the school's large-scale market demand will activate the development of the security industry. In the future, the security market will enter a high-speed development period dominated by public security. At the same time, it will also provide security companies with innovative opportunities. As the leader of China Security Technology Co., Ltd., Tu Guoshen, Zhong An Xiao and Beijing University sign the establishment of intelligent video technology collaborative innovation. Center, this research center will set a good example for the domestic security industry through the country’s most advanced invention patent output, software and hardware implementation, as well as promotion of academic influence and establishment of industry standards.

Campus security emphasizes all-round application, campus security requires integrated systems include: digital video surveillance system, alarm system, perimeter security system, access control system, card system, parking management system, patrol system, integrated security management system, background music And public broadcasting systems, integrated wiring systems, wireless intercom systems, cable television systems. For the one-card system, campus information can also be integrated in the construction of information, so that the same card with different libraries, where the library refers to the database, a card can use its different sectors to store the corresponding data, can be modified to achieve consumer, access control system integration .

All these security systems are centered on digital video surveillance systems, with access control systems and anti-theft alarm systems as the core. Through network interconnection, all technical resources and means are effectively integrated to form a set of automated, highly intelligent, integrated prevention. A modern safety and security system that is capable of meeting campus characteristics and meets the requirements of various campus campuses. For example: campus security office, office, recreation department, study style construction center, life service center, rights and interests protection center, personnel management center, outreach center, The Publicity Department, etc., relate to external security and internal management.

The development of the campus security system is focused on the development of security systems in domestic universities. 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. .

In the course of expansion or reconstruction of colleges and universities, in addition to paying attention to the new demands put forward by the security department, we must also focus on the integration of the old and new 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.

The new generation of cloud computing Qingli campus security work With the maturity of network technology and the decline in 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.
