Surveillance review system

Equipment used to review surveillance data recorded by surveillance systems. Because of the high number (many thousands) of images to review, the review process is time consuming, and must be arranged so as not to miss any important data. Automatic review systems allow the inspector to define regions of interest in the recorded field of view, and the system then selects for the inspector's examination only those images where some movement is recorded within the defined regions. These review systems shorten the review time considerably and have been also shown to increase the technical capability of surveillance by identifying more reliably all images with safeguards relevant activities.
