Abstract: A monitoring system for a periphery of a structure (100) comprises a monitoring module (102) having a detection and ranging system (304, 308) arranged to support monitoring of a portion of the periphery in order to detect passage of a body beyond the periphery. The detector (304, 308) has an imaging resolution that prevents conclusive visual identification by a human operator of the nature of the body. The monitoring module also comprises a video capture apparatus (312, 314) arranged to provide video data. The system also comprises a monitoring station apparatus (200) arranged to receive data from the monitoring module (102). In response to detection of the passage of the body by the detection system (304, 308), the monitoring station (200) enables the operator to review the video data. The video data enables the operator to identify readily the nature of the body detected and thereby to provide confirmatory visual evidence when the body is human.

Abstract: A system for a vehicle is provided for allowing a user of the vehicle or installation to obtain advanced and up-to-date information about the surroundings of the vehicle or installation and the vehicle or installation itself. The system may be located on a marine vessel and it integrates information from a number of different information sources, located both on and off the vessel, en including information from advanced radar and sonar subsystems on the ship, information from conventional instruments and sensors and information from onshore and offshore installations and EO satellites accessed via a control center onshore. The system may communicate with the control center via a communication satellite and/or wireless Internet, if available. A data processing apparatus for processing and presenting the data is also provided. The data is received, processed and presented in three dimensions in space and updated in real time or near real time such that time provides a fourth dimension to the data.
