The system at GRIS NEZ TRAFFIC allows the simultaneous monitoring
of 1,000 tracks, which can be recorded and saved for up to a year.
Advanced functions include alarms signalling risk scenarios, the identification
of tracks infringing Rule 10 of
the COLREGs, the monitoring of ships which make abrupt changes of
course and speed, the observation of ships entering prohibited areas,
and the monitoring of ships at anchor. All situations can be recorded,
archived, and replayed either on screen or in the form of a print
out.
