The annual entrance exam and the college entrance exam are nearing the end of the year when campus security construction is in full swing. Before the exam, busy with the electronic patrol examination system. After the exam, rush to do a new construction and renovation project of the school security system before the summer vacation. Zhang Tianhua, product manager of Tianjin Tiandi Weiye Digital Technology Co., Ltd., said: “In the past, for the education industry, we were able to produce one or two thousand billiard machines a year. Now this number can only meet the market demand for one month. The production line will not stop in the first half of the year. ."
Security systems are widely used in general schools and universities to protect the safety of teachers and students on the one hand and on the other hand to facilitate safety management in schools. As for the general school, it experienced the peak of peace construction last year and began to enter the normalization stage. Xie Qiang, deputy general manager of Sichuan Tianyi Network Service Co., Ltd., a subsidiary of Sichuan Telecom, said: "Last year summer telecommunications installed more than 8,000 campus monitoring sites in Sichuan Province, and now we can receive 1-2 campus security monitoring projects every month." Apart from safe construction, another major focus of General School is electronic proctoring. Tiandi Weiye Zhang Shaohua said, “Before June, there were many electronic survey items in the entrance exams and college entrance examinations, and they were usually done in units of provinces, cities, or districts. Images were uploaded to the examination center of the Ministry of Education to achieve multi-level networking.â€
Compared with general schools, which are mainly affected by policies, security construction in colleges and universities is more for security management needs. Because of the adoption of open management in colleges and universities, all kinds of security incidents have always been headaches for the school. Especially in the capital universities and colleges, the security work during the sensitive period is more challenging. For example, student posters and group trips are the focus of school security work. Peng Tao, a pre-sales manager of Suzhou Keda Science and Technology Co., Ltd., said: “The colleges and universities have more requirements for system functions, and must take care of the management requirements for monitoring audio and video resources in various aspects. We hope that students can acquire more knowledge and information through the Internet. ."
As a whole, the campus security market is still affected by policies. Its construction funds mainly come from central and local government support. At the end of last year, the central government allocated special funds of 3.889 billion yuan to provide a one-off subsidy for the school's campus security equipment and facilities at the compulsory education stage; in March of this year, the Ministry of Finance entrusted the State Council and the Ministry of Finance submitted the fourth meeting to the 11th National People's Congress. Regarding the 2010 Central and Local Budgetary Implementation Report and the 2011 Central and Local Budget Draft Report, the central government's fiscal education plans to spend 296.357 billion yuan in 2011, an increase of 41.623 billion yuan over 2010, an increase of 16.3%; the school itself has annual capital investment. Security system construction or maintenance, these initiatives can support the campus security market scale, and continue to expand.
Because of this, although the campus is not a high-risk place, it will be indispensable for the application of any new technology. In terms of IP applications, the campus plays a vanguard role.
IP-led development of new construction, renovation, and expansion Before 2009, campus security IP applications were not expected to be successful. Qin Yan, the manager of electromechanical technology department of Guangdong Guangfenglong Electronic Technology Co., Ltd., said that the main reason is to build IP surveillance private network investment and share the technical requirements of campus network management. In addition, the past campus monitoring points are not many. The system is adequate. Liu Ke, chief engineer of Beijing Huake Hongtai Intelligent System Engineering Co., Ltd., also stated that the school IP system that was implemented around 2003 had many problems and was costly, resulting in dropped frames and lost packets. "Until 2008 and 2009, the company successively built some IP high-definition projects, and everyone gradually accepted IP systems. Especially in 2010, what we did was IP or IP-led projects." Compared to the past, it was difficult. Now IP has entered the first small peak in campus applications.
The questionnaire survey conducted on this topic found that the vast majority of engineering firms believe that the application of pure IP systems will increase. The more consistent view is that although the budget for the application is limited, because of the relatively high level of knowledge, the school is susceptible to accepting new technologies. With the rapid development and upgrading of the school ground network, the pure IP system will occupy the mainstream market, especially the university security market. .
Judging from the nationwide deployment situation, due to the fact that most of the engineering businesses in the campus area are based on local businesses, the local characteristics are very obvious. This directly leads to different levels of IP application in different regions. According to Li Xinwei, technical director of Beijing Tianchuan Science and Technology Development Co., Ltd., which is based in the Beijing university market, “There is no reason for the school to reform. In 2010, about 10% of university projects in Beijing use IP, which may grow to about 15% this year. The large-scale transformation will take three to five years.†Toneng Yuan, who specializes in the market of Shandong universities, said: “We have researched and conservatively estimated that the Shandong colleges and universities’ IP market will have a scale of nearly 50 million to 110 million. In recent years, new projects will adopt IP. The original system has a transitional period of transformation. Consider the adoption of a network camera during the renovation. For example, the student apartment access control system of Shandong University employs 140 Axis network cameras.â€
Although second-tier cities such as the northwest and northeast are starting late, they have high expectations for IP, such as Shenyang's initiative to adopt IP. In addition, the “211†and “985†engineering schools and other key colleges will also want to adopt IP when they are adding new ones due to the pressure of security.
Compared with the speed of IP in universities, general schools are relatively slow. According to Chen Zhonglin, marketing director of the Ruijie video surveillance division of StarComm, “The most common concern of the General School is whether the point can be basically covered, and the docking with the Board of Education and public security, local monitoring is mainly based on the DVR/DVS mode, is it used? IP mainly depends on the local education committee's requirements.Some local education committees require the upload of high-definition images, which requires the use of high-definition network cameras, as the Chaoyang District Board of Education explicitly requires 4-way high-definition upload to the district education committee."
IP can't be generalized, it's not just shouting slogans, IP also needs to be applied properly.
Guang Fenglong Qin Yan believes that “for those with network management personnel and a high level of technology, a relatively complete network construction, a large scale of projects (more than 100 audio and video monitoring points), application diversification, there is an expansion of demand Campus users, we can recommend the use of pure IP technology monitoring system. We do not recommend the use of pure IP technology monitoring system for small projects, low investment or network is not perfect, there is no professional network management technicians and users do not monitor the expansion needs. The building must use the network camera or analog camera + video server, otherwise there is no way to manage the group; the electronic patrol system needs to use IP when cascading, but the school does not necessarily use IP.
In addition, whether or not IP is used is not a major issue, and ensuring investment, facilitating construction, and meeting usage needs are the key issues. Take the access control system as an example. Qin Yan believes that “it is not appropriate to use the pure IP method for the access control, but rather to use the bus method on the same floor, and to use the IP method when entering the center on different floors.†He analyzed that if each access control card reader uses the IP method If connected, IP ports cannot be connected in a serial hand-in-hand manner. For projects with many access points, the number of network switches configured will be very large. This will result in a large investment. If the bus mode is adopted, the wiring is simple and the cost is low. low. Unless there are special needs departments may require port independence, but this situation is less likely to occur. The so-called IP access control, but the communication between the controller and the management server using TCP / IP protocol, controllers and readers used in most connection between the RS-485, CAN bus and so on. It is not necessary for the reader to open the IP port itself. The cost is too high and the IP resources are wasted.
Integration: Improving the Value of IP Applications According to the survey of this project, we learned that security systems or teaching systems that currently have integrated cases are mainly: monitoring, alarm, access control, card, parking system, electronic examination room, and multimedia teaching. Among them, the monitoring and alarm integration is common, followed by the integration of access control, and then the integration of card, electronic examination room, parking system, of course, the need for integration of multimedia teaching systems, educational management and integration needs.
Huake Hongtai Liu Hao said, "Integration is also an important reason for IP surveillance systems. IP facilitates integration and linkage with other systems. It can also introduce value-added applications for intelligent video analysis and upgrade to a comprehensive management platform." For example, Huakehong Thailand's participation in a university project in Beijing last year requires the upgrading of the monitoring center to an emergency command center and an integrated command and dispatch system.
Due to the reduction of campus security projects in some provinces and cities, some engineering firms/suppliers focused on the campus market began to explore new business opportunities following changes in the market. Taking Guangfenglong as an example, this year the company’s focus is to continue to work on the education industry informatization project construction, and to promote independent research and development of software products and information system solutions in the education industry in accordance with user needs. Qin Yan introduced, “We now propose The concept of audio and video surveillance technology applied in colleges and universities is not only to meet the single requirements of security monitoring, but to integrate security monitoring, multimedia teaching and broadcasting, examination inspections, teaching observations and long-range open teaching applications, comprehensive planning projects and integration Design integrated solutions to achieve resource sharing of audio and video and network transmission equipment, and information sharing between management platforms of different business departments.†Keda Pengtao also stated that “many system resources are reusable, and our later ideas are: As long as the system is based on video applications, integration can be attempted to reduce or avoid user repetitive investment.†The examination room like the university does not need to be connected to the examination center, and it can be constructed in a way that does not conform to the national examination patrol system standard. Facilitate internal management.
For General School, IP and integration are not the current focus of construction, so the demand is not so urgent, college users are more likely to accept pure IP audio and video transmission technology, due to the large number of people with many secondary units and different functions. Integrated systems that are easy to manage based on IP construction are more appealing.
Integrate the needs of multiple departments and add bright spots for IP applications The integration plan mainly involves three departments: network information center, academic affairs office, security department or security department, and other management departments, such as multiplex cameras or other network equipment. The camera meets the requirements for examination inspections, multimedia teaching, monitoring, and distance learning.
“Using Guangzhou University as an example, the school set up a multimedia classroom earlier, because it did not install security monitoring equipment and lost projectors, computer motherboards, etc. In the second phase of construction, each multimedia classroom added cameras and infrared cameras. Alarm detectors, and the integration of monitoring functions and teaching and recording functions, security personnel can only monitor the images in the multimedia classroom during normal holiday or school hours, and can not see indoor images during class hours and exams, and can only look outside The supervisory image of the supervisor. The principal in charge of the teaching can see the situation of any classroom. In the office, the quality of the teacher’s teaching can be evaluated; the classroom can be monitored in the conference room without the need to go to the scene to attend classes.†Guang Fenglong Qin Yan said.
In addition, college dormitory management is also a hot spot for the application of integrated solutions. The intelligent apartment project of Shandong University, such as Tuoengeng, is currently researching and developing integrated platforms for security, firefighting, power supply, emergency lighting, etc.; there is also dormitory management that integrates channel gates, image capture, and campus cards, and students swipe their cards to enter the dormitory. After the building, the terminal of the dormitory management office can display part of the student's information. Terminals distributed in libraries and other places can also view student-related information.
The status quo is that teaching and security are independent in most projects. On the one hand, the school does not understand that systems can be related to each other. On the other hand, security manufacturers do not understand the application of teaching recording and broadcasting systems, and teaching recording and broadcasting system providers are not familiar with security monitoring applications, which requires the establishment of a communication Bridges, integrating multiple requirements, and the guiding role played by the contractor/integrator are very important.
Integration is faced with a wide range of difficult problems. The difficulty of integration is very large, and the problems encountered by the contractor/integrator are various.
The most typical is that school organization and management do not facilitate system integration. In general, campus security is the responsibility of the security department, multimedia/e-learning management, and one-card access to the network information center. Academic administration is mainly responsible for teaching and classroom arrangement. If there is a lack of a lead department or person in or among the three, it is difficult. Shared resources are available, and the school also lacks complex talents. With regard to the integration of fire protection and security, the Security Department has the deputy director of security, and the deputy director of the fire control department. Each person manages the scope of his responsibility and the suppliers he contacts are different.
In theory, system integration sounds good, but is it practical to use it? Tian Chuan Technology Li Xinwei said, “When the card is swiped, the video will pop up, 10,000 students will swipe, and the images will change quickly. Is it really possible to see them all? One day it is estimated that few people will look at these pop-up video images. Moreover, it is too complicated to operate. It's not necessary. After all, the operators are on-duty personnel, not leaders. Integrating the parking system also has objective obstacles. Some parking systems require billing and involve settlement of amounts. If integrated with other subsystems, the security of the data has potential risks. There have been student library deaths, and the school hopes to observe whether the students are in a specific area within a specified time, such as confirming whether or not to attend class by punching cards, but in reality the cards are not necessarily in the classroom.
Guang Fenglong Qin Yan stated, “We initially hoped to make a complete system, but in the course of the operation, we found that the complete system was also inadequate. If there were problems in the public part, all subsystems would be affected. This is a contradiction.â€
How large the market can be brought together by integration is currently unknown. Huake Hongtai Liu Ye said, "We have done a project, the use of monitoring systems for classroom management, the two share an IP camera. But in fact, multimedia teaching is an independent industry, it can cross security only front-end acquisition equipment And the network, backend has its own unique equipment such as recording and broadcasting equipment, courseware production software, etc."
For leaps and bounds, IP still has the potential to improve the capabilities and parameters of space-based network monitoring equipment, and has promoted the use of IP in schools. In the past few years, the effect of using pure IP monitoring equipment in some projects has been verified by facts. However, there will be leaping applications in the future and there will still be room for suppliers to upgrade.
Taking a network camera as an example, there are still room for improvement compared to the extreme analog camera, especially the high-definition network high-speed ball. Huake Hongtai Liu Hao said, "We hope to push HD ball to users, but because there are still some problems with the product, it is not enough to promote it, such as high cost, dropped frames, poor operation experience, etc. Especially in the operating experience On the other hand, if you are accustomed to simulating the ball operation, the HD ball will feel uncomfortable and smooth.†Therefore, he had to use more simulation machines and encoders in his projects.
Another feature that needs to be improved is the "watchdog." Guang Fenglong Qin Yan stated that “the larger the system, the more “guard position†is. The preset position function of the dome camera can be set in advance, but when it reaches the preset position, it needs alarm linkage control. Or manually manual control. It is an incredible and complex operation to control by people every day in a system with thousands of points. Therefore, we propose to combine the preset position with the watch position and let the dome machine automatically arrive at the designated time. Set a preset position."
Another large demand, while the product still to be improved is the management platform. If the stability is not enough, the application of the platform of other industries makes the application of campus features inadequate, and the high-definition compatibility of the module and standard definition are not frequently mentioned in the survey. And.
Huake Hongtai proposed that “the campus has fewer targeted platforms and we need to revise it after we get it.†Spending too much time on the platform makes the original tight schedule even more urgent. Starnet Ruijie Chen Zhonglin said: "A lot of companies have moved platforms that have been used in multiple Safe City projects to campus. There is a big difference between the two. The former emphasizes the effectiveness of forensics, and large investments require the protection of existing investments. Schools focus on prevention, investment does not need too much concern, and new solutions can be used based on local area networks.Some encoder schemes that have undergone multiple analog-to-digital conversions greatly compromise the video quality of large screens and affect the school’s IP performance. The understanding of the project.†In addition, there are engineering companies that reflect the platform is in the process of secondary development and compatibility with other brands, the video is often smooth in the notebook playback test, but on a platform to lose frames, lost packets .
In terms of function and application development, the campus management platform needs to increase investment in research and development. Guang Fenglong Qin Yan suggested that “adding a portrait recognition function, an automatic tracking function, a memory recording quick retrieval function, a variety of IP camera compatibility functions, and a multi-service system function, etc.â€
With the advancement of IP monitoring, several vendors’ platforms have gradually been recognized by campus engineering companies, such as China Wealth, Zhongsheng Yihua, mutual trust, Dongfang.com, Ruijie, and Huasan.
Obviously, the IP security of campus security still requires suppliers to treat the product development specifically. According to many years of experience, Guang Fenglong Qin Yan put forward: “In the concept of security monitoring, if the video is prioritized and the network is not in good condition, the sound may not be transmitted, but the video cannot be lost. The idea in the field of education is that sound is preferred. Can be stuck, the sound can not be broken. This is the biggest difference in product development."
Taking into account both the forward-looking and practical, rational guidance of consumer schools is a market that takes into account both forward-looking and practical. For example, the school will consider the issue of return on investment. The school is different from the first-tier risk prevention unit. It is a fact that it is not possible to use high-end equipment for investment. He will calculate that if there is a 20% failure rate in 100 points, 80 points are still in normal operation. If high-end products are used, About 50 points are running normally, so he would prefer to choose more of the former.
However, schools also tend to be perfect and demand is not proportional to investment. Xing Wang Ruijie Chen Zhonglin suggested that we should pay attention to the most core needs. "For the engineering firm, the project decision cycle and implementation cycle are very long, it is difficult to fully meet customer needs, so we propose 'enough and practical', often organized some school activities, the purpose is to make the school more rational. Businesses also need to return to understand the real needs, after all, the school's funds are limited.†Qin Yan also stressed that “looking at the meal, the ability to do it, is an important principle to follow in the planning and design of the project. Blindly pursue the new high-tech applications, to take the risk of construction. High investment, low equipment reliability, and poor system stability risk."
In addition, some schools choose engineering contractors/integrators to blindly pursue their qualifications and scale, which virtually increases the marketing cost of professional engineering firms, which is also unfavorable. The campus market does not seem to have a high threshold, but it is a market that focuses on guidance. It requires a high degree of professionalism for the project providers. Engineers are usually the main advisers of campus security, and the correct guidance of the project providers is crucial for the healthy growth of the campus IP market in the future.
Security systems are widely used in general schools and universities to protect the safety of teachers and students on the one hand and on the other hand to facilitate safety management in schools. As for the general school, it experienced the peak of peace construction last year and began to enter the normalization stage. Xie Qiang, deputy general manager of Sichuan Tianyi Network Service Co., Ltd., a subsidiary of Sichuan Telecom, said: "Last year summer telecommunications installed more than 8,000 campus monitoring sites in Sichuan Province, and now we can receive 1-2 campus security monitoring projects every month." Apart from safe construction, another major focus of General School is electronic proctoring. Tiandi Weiye Zhang Shaohua said, “Before June, there were many electronic survey items in the entrance exams and college entrance examinations, and they were usually done in units of provinces, cities, or districts.

Guang Fenglong Qin Yan stated, “We initially hoped to make a complete system, but in the course of the operation, we found that the complete system was also inadequate. If there were problems in the public part, all subsystems would be affected. This is a contradiction.â€
How large the market can be brought together by integration is currently unknown. Huake Hongtai Liu Ye said, "We have done a project, the use of monitoring systems for classroom management, the two share an IP camera. But in fact, multimedia teaching is an independent industry, it can cross security only front-end acquisition equipment And the network, backend has its own unique equipment such as recording and broadcasting equipment, courseware production software, etc."
For leaps and bounds, IP still has the potential to improve the capabilities and parameters of space-based network monitoring equipment, and has promoted the use of IP in schools. In the past few years, the effect of using pure IP monitoring equipment in some projects has been verified by facts. However, there will be leaping applications in the future and there will still be room for suppliers to upgrade.
Taking a network camera as an example, there are still room for improvement compared to the extreme analog camera, especially the high-definition network high-speed ball. Huake Hongtai Liu Hao said, "We hope to push HD ball to users, but because there are still some problems with the product, it is not enough to promote it, such as high cost, dropped frames, poor operation experience, etc. Especially in the operating experience On the other hand, if you are accustomed to simulating the ball operation, the HD ball will feel uncomfortable and smooth.†Therefore, he had to use more simulation machines and encoders in his projects.
Another feature that needs to be improved is the "watchdog." Guang Fenglong Qin Yan stated that “the larger the system, the more “guard position†is. The preset position function of the dome camera can be set in advance, but when it reaches the preset position, it needs alarm linkage control. Or manually manual control. It is an incredible and complex operation to control by people every day in a system with thousands of points. Therefore, we propose to combine the preset position with the watch position and let the dome machine automatically arrive at the designated time. Set a preset position."
Another large demand, while the product still to be improved is the management platform. If the stability is not enough, the application of the platform of other industries makes the application of campus features inadequate, and the high-definition compatibility of the module and standard definition are not frequently mentioned in the survey. And.
Huake Hongtai proposed that “the campus has fewer targeted platforms and we need to revise it after we get it.†Spending too much time on the platform makes the original tight schedule even more urgent. Starnet Ruijie Chen Zhonglin said: "A lot of companies have moved platforms that have been used in multiple Safe City projects to campus. There is a big difference between the two. The former emphasizes the effectiveness of forensics, and large investments require the protection of existing investments. Schools focus on prevention, investment does not need too much concern, and new solutions can be used based on local area networks.Some encoder schemes that have undergone multiple analog-to-digital conversions greatly compromise the video quality of large screens and affect the school’s IP performance. The understanding of the project.†In addition, there are engineering companies that reflect the platform is in the process of secondary development and compatibility with other brands, the video is often smooth in the notebook playback test, but on a platform to lose frames, lost packets .
In terms of function and application development, the campus management platform needs to increase investment in research and development. Guang Fenglong Qin Yan suggested that “adding a portrait recognition function, an automatic tracking function, a memory recording quick retrieval function, a variety of IP camera compatibility functions, and a multi-service system function, etc.â€
With the advancement of IP monitoring, several vendors’ platforms have gradually been recognized by campus engineering companies, such as China Wealth, Zhongsheng Yihua, mutual trust, Dongfang.com, Ruijie, and Huasan.
Obviously, the IP security of campus security still requires suppliers to treat the product development specifically. According to many years of experience, Guang Fenglong Qin Yan put forward: “In the concept of security monitoring, if the video is prioritized and the network is not in good condition, the sound may not be transmitted, but the video cannot be lost. The idea in the field of education is that sound is preferred. Can be stuck, the sound can not be broken. This is the biggest difference in product development."
Taking into account both the forward-looking and practical, rational guidance of consumer schools is a market that takes into account both forward-looking and practical. For example, the school will consider the issue of return on investment. The school is different from the first-tier risk prevention unit. It is a fact that it is not possible to use high-end equipment for investment. He will calculate that if there is a 20% failure rate in 100 points, 80 points are still in normal operation. If high-end products are used, About 50 points are running normally, so he would prefer to choose more of the former.
However, schools also tend to be perfect and demand is not proportional to investment. Xing Wang Ruijie Chen Zhonglin suggested that we should pay attention to the most core needs. "For the engineering firm, the project decision cycle and implementation cycle are very long, it is difficult to fully meet customer needs, so we propose 'enough and practical', often organized some school activities, the purpose is to make the school more rational. Businesses also need to return to understand the real needs, after all, the school's funds are limited.†Qin Yan also stressed that “looking at the meal, the ability to do it, is an important principle to follow in the planning and design of the project. Blindly pursue the new high-tech applications, to take the risk of construction. High investment, low equipment reliability, and poor system stability risk."
In addition, some schools choose engineering contractors/integrators to blindly pursue their qualifications and scale, which virtually increases the marketing cost of professional engineering firms, which is also unfavorable. The campus market does not seem to have a high threshold, but it is a market that focuses on guidance. It requires a high degree of professionalism for the project providers. Engineers are usually the main advisers of campus security, and the correct guidance of the project providers is crucial for the healthy growth of the campus IP market in the future.
