The state has increased the construction of the Xueliang project.  But there are still unstable factors in some special environments. In these problems, is video surveillance really in place?

Outstanding campus CCTV issues

The campus CCTV plan is a more complex environment. It is no less than a small society-leaving the campus gate involves social security.  And entering the campus gate involves multiple environments.  such as traffic, outdoor CCTV camera and lens, indoor CCTV camera and CCTV lens, and key area CCTV camera and lens.

In the campus solution, the video needs to be streamed.  That is not only needs to be connected to the relevant government agency data backend.  But also it must allow parents or guardians to log in and view video content at any time. With the development of video surveillance, it is not difficult to realize this demand.  And most enterprises can realize this demand.

However, it is undeniable that during the construction of the Xueliang project, most of the projects still focused on outdoor construction rather than indoor construction. Due to the lack of effective CCTV lens and camera indoors, various events often occur. Investigating the root cause will find that it is not only the user’s own problems, but also many other problems.

Indoor CCTV construction problems

Indoor CCTV lens and camera and outdoor CCTV have always been a tangled problem for related personnel due to the problem of division of ownership. For example, in the ordinary residential area, in the residential area.  It is usually managed by the property department.  And its operating costs are usually borne by the users. To improve the property costs, the users need to be explained and requested. For indoor construction, it is the user’s personal responsibility. For users who have not yet had an incident, security cameras are not suitable for indoor installation.

However, for public areas, especially for privately-established campuses or related training and rehabilitation centers, the minimum configuration is installed in accordance with national regulations. This behavior does not meet the relevant requirements very well, and the related videos shot cannot Adopted by relevant departments.

How to choose better equipment to meet the needs of relevant departments?

Video surveillance equipment selection

With the development of home security, home cameras can meet the video surveillance in most small scenes. Under this demand, some campuses usually use home cameras for the selection of CCTV equipment.

But from the parameters, it seems that it can meet the needs of users, but there are actually many problems-clarity, data security.

Home camera and lens are usually 1.3 megapixels, and currently there are not many that can reach 2 megapixels on the market. Most of them are “pulled” to 2 megapixels by software, which brings extremely low pixels.

Although some camera and lens can be used inside the classroom, they are not suitable for all scenarios—meeting rooms or large classrooms. At the same time, in areas with large environments, people’s facial information cannot be effectively distinguished. In addition, due to too many people in a small area, home cameras cannot effectively recognize all faces.

In this environment, what users need is a camera and lens that can identify all people’s facial information as much as possible within the specified range.

Which cameras can meet this need?

At present, it seems that all high-resolution cameras can meet this demand, but due to the special environment of the classroom, it may not be applicable, especially extended applications based on video surveillance.

In the classroom, the camera is not necessarily based solely on security considerations, and there are multiple issues that take into account student attitudes. How to summarize all the data? This requires effective control of the personal data of each student and teacher.

1.Multi-camera camera

The multi-camera camera uses binocular recognition. Its panoramic camera can effectively monitor the large scene environment, while the detail camera can quickly monitor everyone in real time. It can not only quickly identify everyone’s facial data. In the event of an emergency, the detail camera can be used to record in time, so that all events can be restored in time.

2.Behavior analysis equipment

In terms of behavior analysis, it can be identified in two ways: video analysis and three-dimensional vision.

Video analysis is mainly two-dimensional image analysis, which can quickly locate people in the video to identify the actions of each person. This technology is currently immature and cannot be recognized for some movements. At the same time, it is a 2D picture, and once it is blocked, it cannot be seen and recognized.

In order to solve the problem of 2D pictures, some companies have proposed 3D vision. Through infrared spectrum or 3D structured light, through full coverage in the range, people’s behavior can be effectively identified. However, for more comprehensive coverage of the device, multiple products need to be installed.

Write at the end

For indoor security construction, it is not possible to rely solely on camera and lens. It is more necessary for users to participate in the construction of a safe campus. Security equipment is more convenient for parents or guardians to understand the behavior of guardians on campus, so as to better cooperate with the school .
