The development trend for Video Surveillance Industry
Video surveillance industry chain is mainly divided into four parts: components (including optical lens, sensor chip, processor chips, and other components); monitoring equipment providers (comprising: hardware and software vendors); system integration suppliers, distributors and engineering companies and end customers. The video surveillance system covers front-end collection, transmission and control, display and storage nodes.
From a global perspective, Chinese domestic enterprises occupy certain shares in the mid and low-end of optical lens, processor chips and other key components, but high-end product still relies on foreign manufacturers. As for monitoring equipment products, Chinese domestic companies have price advantage, which is the key factor for currently Chinese domestic products achieving large-scale export.
The trend of video surveillance industry can be described with four directions, namely: digital, high-definition, networking and intelligence, these four trends compliment each other. The so-called digital mainly refers to security video monitoring mode transforming to all-digital video surveillance system, the front-end audio and video capture devices and back-end storage devices all go digital with the core of digitized IP cameras and network video server NVS and other front-end digital collecting equipments.
High definition is easy to understand, clearer monitor screen can exhibit monitoring effect at the largest extent, especially in some special occasions. The most intuitive should be the demand increase of high-resolution IPC; in addition, there are technical upgrading requirements for photosensitive device, chip, transmission system, back-end storage devices and displays, etc.
The largest advantage of networking lies in achieving remotely monitor screen, building wide-range monitoring platform, providing convenience, saving social sources; and its core is also equipping network cameras.
Intelligence is a relatively ideal state, a technology of conducting a graphical analysis to the monitoring video screen with mathematical methods, extracting the useful information in the video. Motion detection, traffic statistics, face, license plate recognition can be achieved through video surveillance. The key of intelligence lies not in information collection, but in the data mining and intelligent analysis, which poses high requirement for software. A fashionable concept “intelligent city” should take video surveillance as core, but currently it is still distant.
