Problems solved by technology
However, the traditional automatic deletion mechanism has deleted this video in order to save space because the relevant video file is too old without prior storage, which will hinder the investigation of the police
In addition, since the video recording range of the cameras in the surveillance system is roughly fixed, the video frames captured by the cameras most of the time have high repeatability. If only older video clips are deleted based on the time of the video files, the remaining The video clips may have few frames or sound movement, so the actual benefit is not great
[0003] Based on the above, the existing related technologies cannot properly serve users

A method for managing video recording storage space in a surveillance system and associated apparatus are provided, where the surveillance system includes at least one camera, and the method is applied to a control circuit of the surveillance system. The method includes the steps of: calculating scores of a plurality of subsets within a series of video recording data of the surveillance system, respectively, wherein the plurality of subsets corresponds to a plurality of time intervals, respectively, and the scores are utilized for determining whether to erase at least one portion of the plurality of subsets; and selecting at least one subset from the plurality of subsets according to the scores, and erasing the subset, wherein at least one score of the subset comprises an extreme value of the scores.
Description
technical field [0001] The present invention relates to recording video data output by a camera, in particular to a method and device for managing video recording storage space in a surveillance system. Background technique [0002] According to the existing related technology, in a traditional digital surveillance system, a data storage device such as a hard disk drive is usually provided for storing the video data output by the camera in the traditional digital surveillance system, wherein when the When the storage capacity of the hard disk drive is insufficient, the traditional automatic deletion mechanism of the traditional digital surveillance system can automatically delete from the oldest video file, so as to reduce the hard disk capacity occupied by video data. The main disadvantage of the traditional automatic deletion mechanism is that the traditional digital surveillance system may delete useful video clips preferentially. Example: It takes a month for a criminal...
