Recording system and method based on 4G/5G network and two-dimensional code scanning recognition

Abstract

The invention discloses a whole-course audio and video recording system based on a 4G / 5G network and two-dimensional code scanning recognition and a use method thereof. The system comprises a background application service system and a law enforcement recorder. An external terminal is connected with the background service application system through a wireless network or a wired network, and the external terminal generates a two-dimensional code. The video recording audio and video file processing unit is used for carrying out unique association on the character string information and the videorecording audio and video file. The law enforcement system further comprises an acquisition workstation connected with the background application service system, and the law enforcement recorder is connected with the acquisition workstation. Audio and video media shot by the law enforcement recorder are directly transmitted to the network background for real-time preview, video recording, streaming media forwarding and intelligent analysis, and the audio and video media transmitted to the background through the 4G / 5G network realize manual or automatic association of two-dimensional code information. Through the unique identification information, which law enforcement recorder or an operator leaks can be traced, and the application industry adopting law enforcement records has wide practical requirements.

Description

technical field [0001] The invention belongs to the technical field of law enforcement equipment, in particular, a full-process audio and video recording system and usage method based on 4G / 5G network and two-dimensional code scanning recognition. Background technique [0002] From the way of formation, QR codes can be divided into two categories: [0003] (1) Stacked two-dimensional code: on the basis of one-dimensional barcode, multiple barcodes are stacked together for encoding. Common encoding standards include PDF417, etc.; [0004] The other is the matrix two-dimensional barcode represented by QR. [0005] (2) Matrix two-dimensional code: In a matrix space, information is represented by black and white squares, black squares represent 1, white squares represent 0, and the corresponding combination represents a series of information, common coding There is a QR code as standard, [0006] At present, many applications use QR codes for encoding and decoding. QR codes n...

Problems solved by technology

In actual use, the video of the law enforcement recorder can be leaked and disseminated to unauthorized Internet, WeChat, Weibo and other media by directly playing back photos, audio and video files, and recording files in the law enforcement recorder, and has been Leaked resources cannot be traced back to the source through effective means; once the photos, audio and video files, and recording files of the law enforcement recorder are collected on the collection workstation or saved in the storage setting, they can be processed at will, copied and cut; law enforcement records can be operated independently By the time the instrument was released, the video could be remade and leaked irretrievably

During the use of the law enforcement recorder, since the memory card can be hot-swapped, the video files stored in the memory card may also be deleted or modified at will.
