Brief introduction
With the advent of a network video surveillance system that relies on embedded technology, network and communication technology as a platform, and features intelligent image analysis, the development of network video surveillance has entered the digital age. Whether it is a solution consisting of an analog camera and a video server, a solution consisting of a network camera alone, or a solution consisting of a mixture of the two, intelligent video surveillance has proven to be a very attractive solution .
Intelligent video surveillance appears as a distributed concept, which expands the surveillance mode to complement each other with decentralization and centralization, and expands the scope of surveillance infinitely. Utilize the ubiquitous Internet and local area network to achieve plug and play in the entire network. The digitization of the whole process from image acquisition, transmission, video recording, and final output is realized, especially when the on-site environment is harsh or inconvenient to go directly to the site. Can perfectly solve cross-regional monitoring needs. In practical applications, security systems often have to be expanded in scale due to increased use requirements. Pre-planning and consideration of expected capacity are directly related to the level of future expansion costs.
Application scenarios and advantages
- Realize 24/7 monitoring
The intelligent video monitoring system can perform reliable monitoring 24 hours a day, and can realize unmanned monitoring mode. It uses a large number of electronic devices to replace personnel and appliances to achieve the purpose of monitoring, greatly reducing the use of manpower and finance, and is more efficient. The intelligent video surveillance system uses intelligent video modules embedded in the front-end equipment or intelligent analysis servers installed in the center to continuously analyze the monitored pictures.
- Improve the accuracy of the alarm
Intelligent video surveillance can integrate powerful image processing capabilities and run advanced intelligent algorithms, allowing users to more accurately define video features, reduce false alarms, and avoid a large number of useless videos. Real-time monitoring, video recording or arbitrary playback of one or more monitoring scenes, authorized networked computers can also realize the monitoring function, avoiding the inconvenience and lack of supervision and management caused by geographical separation.
- Deal with emergencies in time
Be able to set up and identify suspicious activities, prompt management personnel before security risks occur, and make handling plans before relevant specific threats occur. Intelligent video monitoring is simple and convenient to view. Because the fully digital network video centralized monitoring mode is based on the network characteristics, there is no need to increase equipment investment. The remote or local monitoring center on the network can monitor, record or replay one or more monitoring scenes in real time. The authorized networked computer can also realize the monitoring function, avoiding the inconvenience and lack of supervision and management caused by the geographical interval.
- Very high safety capability
Image mask technology prevents illegal tampering with video data. Any authorized computer on the network can perform video backup. It can effectively prevent malicious damage, network failure and disconnection cache function, which can effectively protect video data, video interruption host alarm function, authorized hierarchical management function, and powerful log management function. It is suitable for long-distance transmission, has strong interference ability, is not easily affected by the attenuation of the transmission line signal, and can carry out encrypted transmission.
- Abundant other applications
In addition to being used in the security field, smart video surveillance can also be applied to other areas, such as people counting, crowd control, attention control, and traffic flow control to play a greater role. Multiple display modes; multi-screen intelligent switch round tour; multiple early warning modes; multiple recording methods such as real-time, timing, alarm trigger, start and stop at any time; picture capture printing; intelligent fast video playback query, etc.
to sum up
Intelligence is an important development direction of future network video surveillance technology. The development of the intelligent video surveillance industry has prompted companies to rethink the application boundaries of video systems. Whether it is city security or business optimization, the future of video is full of hope. With the advancement of "safety construction" and "smart city", some traditional security fields such as finance, public security, transportation, telecommunications and other applications have become more in-depth; a number of emerging application fields such as education, medical and health, safety production, etc. have grown rapidly , Civilian fields such as smart buildings, communities, and residential security applications have begun to heat up, and the process of social applications has accelerated, and the personalized needs of users have become a trend. Market applications are gradually extending from first-tier cities to second- and third-tier cities and rural areas, and from coastal areas to central and western regions, and market demand is gradually expanding. With the continuous improvement of cost performance of security systems in the future and the development of high-definition and intelligent technologies, the market application space will continue to grow.
