Video analytics has become a very important topic in computer vision. Many applications and different approaches have been proposed in different fields. This paper introduces a new information visualisation technique that aims to reduce the mental effort of security operators. A video analytics and a HCI module have been developed to reach the desired goal. Video analysis are exploited to compute possible trajectories used by the HCI module to pre-emptively activate cameras that will be probably interested by the motion of detected objects. The visualisation of most interesting views is provided to reduce the mental effort of human operators and allow them to follow the object of interest. Usability tests show the efficiency of the proposed solution.
