Abstract:
A video recording method and system, a terminal device and a computer-readable storage medium. The method comprises: continuously collecting video data of a set range within a field of view of a video acquisition unit and/or audio data around an audio acquisition unit, and automatically and dynamically caching a first video and/or audio data of a first set duration or a first set storage capacity in a circulatory manner to a first storage unit so as to keep the first video and/or audio data updated in real time dynamically cached in the first storage unit; when receiving a first trigger signal, transferring all or part of the first video data and/or the first audio data cached at a time point in the first storage unit to a second storage unit; and at the same time, continuing to automatically and dynamically cache the video data and/or audio data in a circulatory manner collected after the time point in the first storage unit. The prompt recording or compensational recording of events is achieved, i.e. the recording of events will not be missed, and a large amount of useless video data will not be produced.
