Under the influence of big data era and 5G technology, video surveillance technology is becoming
increasingly intelligent, from simple recording to automatic information identification, collision and processing.
The status of video detection has been significantly promoted in the investigation measures, and it plays an
increasingly important role in helping public security organs to complete more tasks. Video surveillance is not a
partial change, but an overall transformation, from the front-end information collection system (camera), to the
information storage system, and then to the terminal information processing system, all upgraded to intelligent
equipment. At present, human face recognition technology and vehicle detection technology are the most
commonly used in public security work. It has played a great role in the process of case investigation.
