0 Introduction
With the continuous development of society and the economy, the scope of human activities has expanded dramatically, and man-made security problems have become increasingly dynamic and complex. Natural disasters are also showing characteristics of suddenness and severe harm. High-tech crime is on the rise, new security problems are emerging, and people's working and living spaces are threatened from multiple directions. To avoid personal injury and property loss, and to ensure that people's work and life are not disturbed, comprehensive security systems targeting various major security threats have emerged. A comprehensive security system refers to a security system that utilizes various high-tech monitoring methods and information processing technologies to monitor various living environments, promptly report information on various accidents, disasters, and illegal events in the environment, and thus prevent and effectively handle security and safety issues. University campuses, as living environments for specific groups of people, play a vital role in ensuring the safety and stability of the environment for the overall stability of the country and society.
1. The concept of campus security system
The campus integrated security system is based on general residential environment security systems, but takes into account the characteristics of universities—numerous buildings, dense and complex populations, and diverse functional environments. It fully utilizes information technology and, in accordance with relevant regulations from national education and public security departments, conducts real-time monitoring of key and vulnerable areas on university campuses, enabling timely and effective measures to be taken. This achieves a comprehensive security system that combines human, physical, and technological security measures. Its main characteristics are:
1.1 Characteristics of Importance. Universities are important places for the country to cultivate high-level builders and successors. Students living on university campuses are a special group, and their personal safety and property security affect the stability of thousands of families. Therefore, the comprehensive security system established on university campuses has unique importance compared to other residential areas. It is a key area for monitoring and prevention, and it is of great importance both technically and in terms of awareness.
1.2 High-Tech Characteristics. In my country, universities are important sites for technological production, and correspondingly, security incidents and disasters also possess a high-tech nature. Due to the influence of the environment, the knowledge level of the population gathered on campus leads to a higher level of technological sophistication in security incidents, illegal activities, and disasters compared to other areas. Therefore, preventing such incidents must be correspondingly addressed with high-tech means and measures, which determines the high-tech characteristics of the comprehensive security system on university campuses.
1.3 The Characteristic of Widespread Nature. In other densely populated areas, the design and management of comprehensive security systems are characterized by the independent work and actions of public security departments or security agencies. However, in the unique environment of universities, the characteristic of comprehensive governance is very obvious. It requires broad participation and the mobilization of all factors in the environment conducive to the system's implementation. Therefore, this determines the wide-ranging nature of comprehensive security systems on university campuses.
1.4 Prevention-oriented approach. Security systems in other environments, besides emphasizing prevention, focus more on post-incident handling, primarily providing crucial information for incident response. However, in the specific environment of a university campus, considering the significant impact on society, major instability incidents are generally not permitted. Therefore, a comprehensive security system on a university campus must prioritize early warning and prevention, nipping potential incidents in the bud. Thus, the primary function of a comprehensive security system on a university campus must be the prevention of various security incidents.
2. Composition of the Campus Integrated Security System
To better foster a conducive teaching and research atmosphere and ensure a safe and secure environment on university campuses, establishing comprehensive security systems is becoming increasingly necessary. Based on the basic functional requirements of current security systems, the system primarily consists of three parts: information collection, information transmission, and information processing. Through the proper functioning of these three parts, information relevant to resolving campus safety issues is promptly transmitted to relevant functional departments, enabling them to make correct security management decisions and effectively handle various emergencies and disasters.
2.1 Information Collection Section. The main function of the information collection section is to obtain information on various personnel and events within the campus area in a timely manner. This is primarily achieved through CCTV surveillance systems or infrared detection systems. Information collection encompasses a wide range of content, and the collection channels are typically not limited to a single approach. Multiple lines of defense are often established within the security perimeter, with layered management and control, to obtain relevant information that is beneficial for security decision-making.
2.2 Information Transmission Section. After the information acquisition equipment receives various useful information, it needs to transmit this information to the information processing system in a timely manner so that decision-making equipment or organizations can obtain the correct information. The information transmission section plays a crucial role in the function of the entire system. Typically, the information transmission medium, such as fiber optic cables and telephone lines, must be considered; the distribution of the information transmission medium is also a problem that must be carefully studied when designing a security system, for example, how to minimize transmission distance and information loss during transmission.
2.3 Information Processing Section. The information processing system is the core and heart of the entire integrated security system. It undertakes all the work of processing the collected information and provides the most direct information support for security management decisions. The information processing section is usually referred to as the "monitoring center" in a security system. It is responsible for tasks such as dynamic image monitoring, display, control, recording, command, dispatch, and power supply for the entire security system.
Regardless of the specific functions of a campus integrated security system, its components are all the three mentioned above. In the specific environment of a university, the main functions of the security system are focused on preventing crimes committed by individuals and preventing incidents. Preventing crimes committed by individuals is primarily achieved through a CCTV system. This system collects, transmits, and processes information to monitor and identify potential security risks from various suspects in real time. Preventing incidents is mainly achieved through an alarm system. This system collects early warning information about various disasters and accidents on campus, enabling relevant departments to make timely and accurate accident assessments and security management decisions. Its implementation also involves the three components mentioned above. Therefore, a complete campus integrated security system should be a comprehensive security management system comprising two main parts and three stages: a CCTV system and an anti-theft and disaster alarm system.
3. Establish an intelligent campus security system
In addition to closed-circuit television monitoring systems, perimeter burglar alarm systems, and fire alarm systems, a comprehensive security system based on an intelligent campus should also include intercom/video systems, electronic patrol systems, parking management systems, access control systems, and public address systems.
3.1 Intercom/Visual Control System: Security doors and intercom devices are installed at the entrances of various office buildings, buildings, and faculty residences to enable visitors to communicate/visually with residents (households). Voice and image transmission is supported. The electronic locks of security doors can be remotely opened via indoor units, or the security doors can be opened using passwords, keys, or access cards via the main unit at the entrance. In case of a fire alarm, stairwell doors can be automatically unlocked, and alarm signals can be sent to all occupants. This system is primarily used in the residential buildings of campus faculty and staff.
3.2 Electronic Patrol System This system can designate patrol routes for security personnel to patrol various areas and key locations on campus, and install patrol points. Security personnel, carrying patrol recorders, arrive at the patrol points according to the designated routes and times, record their observations, and transmit the recorded information to the monitoring center. Management personnel can review and print the security personnel's work reports, strengthening security personnel management and achieving a combination of human and technological security measures.
3.3 Parking Management System With the improvement of people's living standards, the number of vehicles in campus areas is increasing. Therefore, a parking management system should be a future development goal for comprehensive security systems. The main function of this system is to control the entrances and exits of campus parking lots, effectively manage the entry and exit of vehicles belonging to both internal and external personnel, and manage fees for these vehicles. This includes recording the entry, exit, and parking times of various vehicles, managing the storage of internal vehicles, and managing fees for external vehicles.
3.4 Access control systems are primarily used at the entrances of important departments. Users enter and exit the gates using contactless proximity cards. Opening and closing are programmed on the control host via computer. The system can arbitrarily set the card usage time and location. The status of the gate, including whether it is open/closed, who entered, when, and where, is recorded in the computer. The system can also coordinate and link with closed-circuit monitoring, burglar alarms, and fire alarms via hardware contact connections or gateways.
3.5 Public Address System: Speakers and other audio equipment are installed in campus squares, lawns, green spaces, and road intersections. These systems are jointly controlled by the monitoring center and other relevant departments, broadcasting music, announcements, and entertainment programs daily in the mornings and evenings, and at specific times (between classes, rest periods, etc.). In case of an emergency, the monitoring center can forcibly switch to emergency broadcast mode to broadcast various disaster alarms or event information. The construction of a comprehensive security system based on an intelligent campus must be based on the actual conditions of the campus. It must meet the security requirements of the campus area while also considering reasonable economic efficiency. Blindly pursuing large-scale and comprehensive systems should be avoided. The above lists some optional subsystems for building an intelligent campus security system. Within the limits of available funds, some or all of these can be selected for application.
Since entering the 21st century, Chinese society has rapidly entered the information age. In today's era of rapid technological development, university students, as the future builders and successors of the nation, have their learning and living environments impacting not only their own healthy growth but also the stability of numerous families and society. This situation has made campus security management not only a matter concerning the local environment but also a crucial issue affecting the stability of the entire society, increasingly becoming a focus of attention for all sectors of society and a significant topic of concern for many scholars.
For the specific environment of university campuses, it is essential to utilize effective technological means and management methods to conduct stable, long-term, real-time monitoring to ensure campus safety. We must also actively seek to change the means and methods of campus security, continuously developing campus security models towards informatization, integration, networking, and proactivity to adapt to the ever-evolving demands of society.
