Embodiment Construction
[0031] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0032] Single police law enforcement video and audio recorder is an audio and video recording device that is easy to carry with you. It is widely used in law enforcement departments, such as police and other city management personnel when they are on duty. The vehicle-mounted hard disk video recorder is mainly used for vehicle safety monitoring, and for law enforcement agencies, it is generally us...

The present solution proposes a data recording method, a system, a video and audio recorder and a vehicle-mounted hard disk video recorder. The data recording method comprises: a body-worn video and audio recorder acquiring first data, and sending the first data to the vehicle-mounted hard disk video recorder; the vehicle-mounted hard disk video recorder acquiring second data, and sending the second data and the received first data to a monitoring server; the monitoring server receiving and recording the first data and the second data, the first data and the second data being associated to each other by means of identification information contained in a data field. When the work is ended, the law enforcement personnel can directly retrieve, on one monitoring server, associated data acquired by multiple different devices, so as to play back same, thereby avoiding searching for related data one by one from system servers of different devices, improving operation convenience.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a data recording method and system, a video and audio recorder and a vehicle-mounted hard disk video recorder. Background technique [0002] When law enforcement officers are on duty, they often need to record data such as sounds, images, and positioning of the law enforcement scene. These data will become important evidence for dispute resolution and case inference. At present, BWC (Body Worn Camera) is generally used to record the relevant data of the law enforcement scene. At the same time, in order to conduct comprehensive audio and video monitoring of the law enforcement scene, MDVR (Mobile Digital Video Record) is the vehicle-mounted hard disk video recorder to record the live environment synchronously. [0003] However, when the law enforcement personnel play back the data recorded by the single police law enforcement video and audio recorder and the vehicle hard ...
