<p>The system has electronic sensors (600) e.g. infra-red cameras, generating data flows that are distributed in a zone, where the data flows represent activity in zones covered by the sensors. Information contained in the data flows are displayed on a visualization interface (603) e.g. mobile screen such as personal digital assistant (PDA), and positioned in a three-dimensional virtual representation of a supervision zone. A processing server (602) comprises units to predict movements in non-covered zones by extrapolation and/or interpolation of data contained in the available data flows.</p> |
