Intelligent analysis technology relieves bandwidth pressure

With the continuous advancement of major projects such as the National Emergency Response System, Safe City, Safe Construction, and Science and Technology Strengthened Police, the domestic video surveillance market has good prospects. The application of intelligent video-related products will grow from the relatively concentrated area to various industries as the market size of video surveillance continues to grow. Intelligent analysis has obvious advantages in solving traditional storage, easing bandwidth pressure, mass analysis, and so on. Industry applications do not expand.

Intelligent analysis technology alleviates the pressure of bandwidth In the current monitoring system, the storage and transmission problems are the first difficulties, and a large amount of useless video information is stored and transmitted, which wastes storage space and increases bandwidth. The purpose of intelligent analysis is to store video data. The space is reduced to relieve the pressure on the bandwidth, or for some useless videos, the low stream method is used for compression or transmission, which is more convenient for the entire system to investigate or use, and the application value of the monitoring system is improved.

Current intelligent monitoring technologies mainly include: identification, track identification, and environmental judgment compensation and recognition. Identification includes face recognition, license plate number recognition, vehicle type identification, vessel identification, traffic light identification, and the like. The most critical requirement for the intelligent monitoring technology of identification is the accuracy of identification, and the best assurance is that it is above 98%, so that it can better meet the needs of most monitoring customers. This is the more common purpose of intelligent analysis. Trajectory identification mainly includes virtual warning lines, virtual alert areas, intelligent tracking, number statistics, traffic statistics, appearance and disappearance of objects, sudden personnel movements, sudden personnel gathering, etc.; environmental judgment compensation knowledge mainly includes rain, snow, heavy fog, etc. Bad weather, low light conditions at night, camera blocking or shifting, camera shake, etc. Intelligent monitoring technology can achieve a more normal monitoring function in the harsh video environment.

When the video affected by the environment is unclear, people in the screen are discovered as soon as possible, or an alarm is issued after the camera is judged to be misaligned. Such functions are universally adaptable and most monitoring sites have potential needs.

Intelligent Video Analysis System The company that has been engaged in the integration of security and video surveillance systems for many years and product research and development has furthered the traditional monitoring technology while introducing intelligent analysis into video surveillance. At present, the intelligent analysis of video has been applied to monitoring systems in the electric power industry and safe cities.

1. Video Surveillance System in Power Industry Substation Video Surveillance system in the power industry currently encounters anomalies that are usually handled afterwards and are often too late. Therefore, in order to prevent them from happening, perimeter protection can be carried out within a certain range within the substation. When suspicious persons are found to be invading or entering the warning line, the monitoring system is required to automatically detect the intrusion target, identify its intrusion trajectory, and issue alarm notification management. Staff to deal with.

Set all intrusion-preventable areas within the perimeter monitoring zone as zones. In this way, when an intruder invades the protection zone, it will be automatically locked and identified by the intelligent monitoring system, and an alarm will be issued at the same time. Here, the alarm is divided into two types: front-end and back-end. The front-end alarm can be realized through an audible and visual alarm. When the intruder triggers an alarm, the monitoring system will sound an alarm to warn the intruder and open the light to prevent the intruder from hiding. The back-end alarm is implemented in the system software platform. Through the management personnel's handling of the intrusion behavior, it can achieve "prevention beforehand" and avoid losses.

2. Safe City Monitoring System For the safe city monitoring system, on the one hand it mainly embodies in some important road sections, communities, public places, etc. to monitor and alarm the suspicious targets that appear through video surveillance. On the other hand, it focuses on the later operation and management of the monitoring system, through the video analysis technology to detect the front-end camera common faults and video image quality problems, to achieve effective monitoring system maintenance.

The demand for video monitoring in Pingan City is complex and the system capacity is huge. It involves not only the monitoring of traffic vehicles, personnel gathering and monitoring, illegal alarms, illegal parking and other intelligent traffic monitoring, but also the appearance of suspicious persons in the community and the alarm of stay, etc.; even To integrate the Internet of Things and cloud computing technologies, build massive video storage and content analysis and retrieval systems.

Conclusion As far as the market demand is concerned, the current market's awareness of intelligent video analytics is constantly improving. Security and Video Surveillance System Integration and Product R&D Company will rely on years of system integration and product R&D experience to fully understand the needs of market segments in different industries, combine intelligent video analysis and detection technology with security monitoring industry, and build reliable and practical intelligence. Analytical applications contribute to the development of intelligent applications for security monitoring.

About Intelligent Analysis Technology refers to the computer image visual analysis technology, which analyzes and tracks the objects that appear in the camera scene by separating the background and the objects in the scene. According to the video content analysis function, the user can preset different alarm rules in different camera scenes. Once the target has violated the predefined rules in the scene, the system will automatically send an alarm, and the monitoring workstation will automatically pop up alarm information. A warning tone is issued, and the user can click on the alarm information to realize the scene reorganization of the alarm and take related measures.
