Claim One:
1. A method for auditing video analytics data through review of selective subsets of video frame images, the method comprising: in response to a triggering alert event, a processing unit generating a subset of frame images from a video stream of a plurality of frame images of a scanning station as a function of a temporal relationship of each of the subset frame images to a scan of a bar code that is associated with the triggering alert event and reported in log data from a scanner area of the scanning station, the subset of images consisting of: a pick-up frame image showing a pick-up area of the scanning station at a predetermined amount of time prior to a time of the reported scan of the bar code that is selected so that the pick-up frame image is expected to show a person picking up an item associated with the bar code from the pick-up area, wherein the pick-up area is different from the scanner area; a scanning action frame image showing the scanner area at a time of the reported scan of the bar code that is contemporaneous with the triggering alert event and that is expected to show the person moving the item over the scanner in the scanning area; and a deposit frame image showing a delivery area of the scanning station at a predetermined time after the time of the reported scan of the bar code that is selected so that the deposit frame image is expected to show the person depositing the item in the deliver area, wherein the delivery area is different from the scanner area and the pick-up area; the processing unit presenting the generated subset of frame images to a human auditor for review in a temporally sequential order in association with a text identifier of the item that is registered with the reported scan of the bar code and without any other of the video stream frame images to enable the human auditor to determine whether the triggering alert event is a true or false alert, or whether additional image frames from the video stream are required to determine whether the alert event is true or false; and in response to the human auditor determining from the subset of frame images presented in the temporally sequential order in association with the text identifier without any other of the video stream frame images that the additional video frames are required to determine whether the alert event is true or false, the processing unit presenting the additional image frames from the video stream to the human auditor for review.
