Harbour Security

Surveillance camera

The successful detection and tracking of underwater noise sources is of particular interest not only for the monitoring of marine life, but also for reducing potential threats to port and harbour security. The use of passive acoustics is a cost-effective solution to the monitoring of unidentified underwater targets, whether hostile, friendly, or purely environmental.

Underwater acoustics are used in the interest of having an undetectable surveillance system. A common method of tracking and monitoring environments is the utilization of passive acoustic systems including hydrophoneshydrophone arrays, and radio buoys. If real-time data is needed the Ocean Sonics GSM Radio Buoy or Coastal Drifting Buoy can supply instrument power and a link if cables are not possible. This link sends hydrophone data over the internet to the user’s desktop.
