1. A computer implemented method of recording the occurrence of a predetermined event associated with a moving object, the predetermined event captured using an image capturing device directed towards a target region associated with the predetermined event, the method comprising:

  • a) the image capturing device acquiring a series of temporal related image frames including the target region, each image frame including pixel data representative of the image frame;

    b) compressing the pixel data associated with one or more of the image frames using a compression process configured to generate one or more motion vectors representative of the moving object, step b) including;

    b1) compressing the pixel data associated with the one or more image frames using a compression process configured to generate one or more motion vectors representative of the moving object;

    b2) communicating the compressed pixel data of step b1) to a data storage device; and

    b3) extracting the one or more motion vectors from the compressed pixel data communicated to the storage device;

    c) determining if the predetermined event occurred based on the one or more motion vectors representative of the moving object; and

    d) recording and incrementally counting the occurrence of the predetermined event if step c) determines the predetermined event occurred.
