Surveillance system is called CCTV (Closed Circuit Television Surveillance System), which has slowly faded in the past 5 years, and has been gradually replaced by Video Surveillance System. With the advancement of technology, video surveillance systems have undergone significant changes. The first is the scale, ranging from dozens of cameras to hundreds, tens of thousands, and even millions of video networking applications, so there are Safe City, Skynet Project (from “Skynet recovery without leakage”), Xueliang Engineering (from “the eyes of the masses are discerning”) such a large-scale city-level video surveillance project; second is the degree of intelligence, from the initial surveillance to the motion detection alarm, then to the leftover alarm, cross-line alarm, and then to the near Two years of relatively hot face recognition, human body recognition, vehicle recognition, object feature recognition, etc.; finally, the application range of video surveillance is getting wider and wider. Video can be used for card-free parking lot access, access control, attendance, consumption, and even use In the intrusion alarm system.
The impact of artificial intelligence on video surveillance makes the system more intelligent, so it can be called an Intelligent Video Surveillance System (Intelligent Video Surveillance System). “GB/T 28181-2011 Security and protection video monitoring network system information transmission, exchange, control technical requirements” defines “Security and protection video monitoring network system (Security and protection video monitoring network system)” as “for the purpose of security precautions, Comprehensive application of video and audio monitoring, communication, computer network, system integration and other technologies, built in cities and large venues with information collection, transmission, control, display, storage, processing and other functions can realize the interconnection of different equipment and systems, An integrated network system with intercommunication and control.
“GB/T 50348-2018 Safety Protection Engineering Technical Specification” defines “Video Surveillance & Control System (VSCS, Video Surveillance & Control System)” as “electronics that uses video technology to detect and monitor fortified areas and display and record on-site images in real time. System and network.” From the definition of English, the control function has been added.
Broadly speaking, the intelligent video surveillance system also covers images (Image, for example, the bayonet system mainly uploads picture information), audio, so the intelligent video surveillance system can also be called the intelligent audio and video image surveillance system.
