Intelligent video surveillance technology stems from computer vision, a key branch of artificial intelligence. As an emerging security solution, it holds great potential for future growth. With the rising demand for intelligent analysis applications, smart video systems are increasingly being integrated into the security field, offering vast opportunities and promising development.
As we enter the 21st century, public safety has become a global priority. Security monitoring systems are now deeply embedded in all aspects of society, influencing and reshaping daily life. The rapid advancement of the Internet, 3G wireless communication, and intelligent multimedia processing technologies has provided strong support for the development of networked intelligent video surveillance systems. Today, these systems are widely used across various sectors such as security, government, banking, education, and transportation. In China, the video surveillance market is expanding rapidly, with growing demands and a diverse range of monitoring equipment. Users continue to push for more advanced features and higher performance from their surveillance systems.
With the evolution of the security industry, intelligent video analytics has emerged as a critical tool. Manufacturers are actively investing in research and development, aiming to refine and improve this core technology for future growth. Although intelligent analysis is being applied in many fields, current solutions still suffer from homogeneity and immaturity, struggling to meet the increasingly specialized needs of different industries.
In practical applications, smart analytics are often divided into areas like public security, law enforcement, and industry-specific use cases. For instance, law enforcement focuses on pattern recognition such as license plate and face detection, while security systems emphasize intrusion detection, crowd monitoring, and suspicious behavior identification. In the entertainment and retail sectors, the focus is on object and personnel protection, ensuring that items are not lost or stolen and detecting abnormal activities. In the tobacco industry, behavior analysis helps detect unauthorized activities and equipment malfunctions.
Most intelligent video analytics applications target three main categories: people, vehicles, and objects. Beijing Wenan categorizes them into public safety prevention, data statistical analysis, and intelligent traffic monitoring. Public safety applications provide early warnings for suspicious events, while data analysis offers insights for decision-making. Intelligent traffic monitoring, such as license plate recognition and illegal parking detection, is already well-established and widely implemented.
In addition, companies like Beijing Monsteel Technologies have developed tools to monitor video quality, identifying issues like image loss, snow, blurring, and color distortion. These tools help maintain system reliability by quickly detecting and addressing front-end camera faults.
Different industries have unique requirements for intelligent video analysis. For example, in safe cities, the system may detect fights or thefts, while in banks, it can identify fraudulent activities like fake keyboards or card skimming. In transportation, it alerts about traffic violations and congestion. To fully realize the value of intelligent video analysis, it's essential to tailor solutions to specific industry needs.
Prisons, for example, require robust perimeter and crowd monitoring to prevent escapes and conflicts. Airports and public places need effective detection of abandoned objects to prevent threats. Remote locations like nuclear plants and oil fields demand high-perimeter security due to limited access but high risk.
Image clarity is crucial for accurate video analysis. High-definition cameras provide richer details, improving the accuracy of recognition tasks like face or license plate identification. However, HD video increases storage and processing demands, requiring more powerful backend systems.
While HD and non-HD intelligent analysis share similar principles, the results differ significantly. HD improves efficiency, providing more detailed information and better recognition rates. Smart systems also offer fast response times, efficient monitoring, and powerful data analysis capabilities.
At the core of intelligent video analysis is motion detection, which identifies moving targets and separates them from the background. Challenges include algorithm robustness, accuracy, and real-time performance. Robust algorithms must handle changing lighting, occlusions, and complex scenes. Accuracy involves balancing false alarms and missed detections, while real-time performance requires efficient computation to manage large data volumes.
Despite its potential, the intelligent analysis industry faces challenges. Environmental factors like lighting changes, occlusions, and cluttered backgrounds complicate algorithm design. Balancing real-time performance with robustness remains a key technical challenge.
Industrialized development is essential to address these challenges. Tailoring solutions to specific industries—such as prisons, transportation, or airports—can lead to more accurate and efficient systems. By focusing on application-specific needs, intelligent video analysis can better meet user expectations and deliver greater value.
In conclusion, intelligent video surveillance has evolved from computer vision into a vital security tool. After years of technological progress and market adoption, it is now becoming a reliable and essential part of modern security infrastructure.
