With the vigorous advancement of the construction of a safe city, video surveillance systems have been widely used in the investigation of public security organs, and are playing an increasingly important role. Video detection technology has become the next step after criminal technology, mobile technology, and network detection technology. The fourth supporting technology for investigating and solving cases.

At present, during the investigation process of public security organs, due to the lack of the "most common and common" video application, the application of video data is inefficient, and it is easy to miss the golden opportunity for case detection, which increases the difficulty of detection. In addition, there is a lack of an actual combat platform suitable for video investigation services, and the various police types "do their own affairs and are not related to each other", and data sharing cannot be achieved.

In response to this situation, Hikvision has launched a video surveillance application solution, which aims to transform video images into front-line combat effectiveness of public security organs, and transform video surveillance work into public security organs to fight "combined warfare, technological warfare, information warfare, and evidence" It is an important means of "war" and closely integrates video investigation with other professional technical means, and comprehensively applies it to effectively improve the actual combat level of video investigation and provide powerful technical support for detecting cases, fighting crime, and maintaining social harmony and stability.
