According to the news, in order to ensure that the China Pavilion was infallible during the exhibition, the relevant units put forward the "highest level" requirements for the security system of the China Pavilion, and decided to adopt the most advanced security technology, which represents the "HD" and "Intelligence" of the latest trends in the security industry. "Technology is widely used.
Expo China Pavilion: "Comprehensive Intelligence" Security Needs
It is understood that the World Expo China Pavilion security system draws on the design experience of the world's major conferences, events and events venues, and established the "all-round, three-dimensional" construction goals, especially in the deployment of intelligent monitoring systems. The requirements, including the integration of a variety of the latest intelligent video technologies, are the main requirements:
Illegal intrusion personnel automatically detect and alarm. In order to prevent someone from entering the China Pavilion without permission, it is necessary to conduct intelligent analysis of the video in the perimeter area of ​​the library area to detect the perimeter intrusion behavior; when it detects the target invading the perimeter of the China Pavilion, an alarm is generated and the dome camera is driven. Automatic tracking, forensics of intrusion targets.
Automatic detection of abnormal events. Intelligent analysis of videos in important areas of the China Pavilion, testing a variety of anomalous events, including detection of anomalies, items, item placement, graffiti, illegal parking, etc.
Self-test for normal operation of the device. In order to ensure the normal operation of the monitoring system of the China Pavilion, the system needs to support the abnormal state detection function of the camera to detect various abnormal states of the camera, including disconnection of the video line, destruction of the camera, and movement of the camera.
Quickly collect evidence afterwards. In order to quickly locate and collect evidence after an abnormal event occurs, the system needs to have a post-event retrieval function, which can perform fast event retrieval on any video in the system and locate the time point of the abnormal event in time.
At the same time, it has a variety of video monitoring functions. The system needs video surveillance system functions such as video preview, video storage, video playback, log management, fastball control, and electronic map.
......
System implementation: the highest level of security in today's security
Due to the large-scale construction of the China Pavilion and the wide coverage of the monitoring area, in order to meet the above requirements, the intelligent monitoring system must take into account the wide range of strict prevention and the lack of a small goal. Therefore, the system is deployed in intelligent technology applications, functional perfection, equipment configuration, etc., all of which reflect the characteristics of “big, full, newâ€.
It is understood that the China Pavilion intelligent video surveillance system involves more than 100 intelligent video analysis points (including high-definition cameras, intelligent trackball machines), in the entire Expo Park, whether it is using high-definition products or intelligent trackball machines, the number of Chinese pavilions At the same time, the system is equipped with complete intelligent video surveillance equipment from front-end video capture to back-end analysis processing and management. It has become the most complete intelligent video analysis in China and even in the world. One of the major projects of function.
Intelligent video analysis
The intelligent video analysis product in the system adopts the detection, tracking and classification technology of the moving target for the input video stream, and the image recognition algorithm such as background modeling, target segmentation, tracking and classification in the video, completes the image to event parameter. The transformation enables real-time detection of various emergencies.

The user can configure the time period.
Challenge: HD intelligent monitoring of large and small targets
Intelligent tracking
In the China Pavilion video surveillance system, the size of the surveillance area and the details of the target are a contradiction. If the surveillance area of ​​the camera is large, it is difficult to get the details of the target; if you want to get the details of the target, the surveillance area of ​​the camera will be very narrow. In order to effectively solve the above problems, a scheme of the L/F dual camera tracking system is deployed.
The system consists of two cameras, one fixed camera as the main camera (Leader), which monitors the large area; and one high-speed dome camera as the follower to get the details of the target. When the main camera detects a suspicious situation, such as crossing the virtual warning wall, entering the exit warning area, squatting, etc., the main camera sends a command to control the pan/tilt rotation and lens zoom from the camera (ball machine), and locks the target that triggers the alarm and Automatically track it so that the target continues to zoom in to be displayed in the center of the screen, so that you can see clearer target features for real-time judgment and post-mortem forensics.
The effect of dual camera tracking is that the static camera has a wide field of view and can monitor a wide range of areas, but it is difficult to get details for the target. With the ball machine, the ball machine can automatically lock according to the information provided by the static camera. Track the target so that the target is at the center of the field of view with a certain magnification, and get rich information about the target.
Since the current video surveillance video is mainly in CIF and 4CIF formats, the image resolution is up to 704*576, which has defects such as unclear images for key targets or regions. In order to improve the current situation, the system uses high-definition cameras to monitor large areas, and at the same time, it performs high-definition capture processing on the alarm targets that trigger the invasion of the Chinese pavilion perimeter. The saved pictures reach 1.4 million pixels and the resolution is 1360*1024. Can greatly improve the clarity of the picture, while providing high quality images for event forensics.
