1. A method of searching for clip differences in recorded video data of a surveillance system, comprising:

  • dividing recorded video data of a surveillance system into a plurality of time periods;

    displaying a plurality of first clips simultaneously on a display, wherein each first clip displays a same scene but a different time period of the recorded video data;

    selecting the first clip having the maximum difference compared with an adjacent first clip;

    dividing the time period represented by the selected first clip into a plurality of time periods;

    displaying a plurality of second clips simultaneously on the display, wherein each second clip displays a same scene but a different time period of the selected first clip;

    selecting the second clip having the maximum difference compared with an adjacent second clip;

    displaying the selected second clip for determining the exact time point having the maximum difference in the selected second clip when the time period represented by the selected second clip is shorter than a predetermined time period; and

    dividing the time period represented by the selected second clip into a plurality of time periods to repeatedly use the next layer of clips to determine the exact time point having the maximum difference between the next layer of clips when the time period represented by the selected second clip is not shorter than the predetermined time period.
