This invention provides a method and related equipment for multi-video segment aggregation and association. First, the start and end times of evidence are generated based on multiple video segments recorded by a video device, and this information is stored in a recording list. When a video segment in the recording list meets the evidence generation conditions, evidence is constructed based on this information and stored in a search queue, where the evidence at least includes a time range. Then, for each piece of evidence, relevant alarm logs are retrieved. If the alarm interval of the alarm log overlaps with the time range of the evidence, they are associated to construct complete evidence. Finally, the complete evidence is added to an upload queue and uploaded to a server. By intelligently aggregating multiple video segments in the recording list, they are integrated into complete evidence, and the start and end times are automatically maintained. This effectively records all recording time periods included in the evidence, achieving accurate matching and aggregation, while automatically associating alarm information and tags, requiring no manual intervention and significantly improving work efficiency.
