Improving safety and situational awareness

In the last decades, marine radar and AIS have made boating safer by improving situational awareness and avoiding collisions at sea. However, radar and AIS have shortcomings:

  • Radar data often requires experienced users for proper interpretation.
  • Smaller objects, such as unsignalled craft, buoys, or floating obstacles will typically not be detected, neither by radar, nor by AIS.
  • Existing tools do not provide sufficient support for MOB situations.

Sentry addresses shortfalls of existing safety equipment with a radical new approach, combining latest sensor technology with machine learning and artificial intelligence Sentry will automatically detect and recognize objects at sea by detecting temperature differences of 0.09° F, based on the experience of millions of recognized marine objects, and based on more than 300,000 nautical miles traveled at sea, Sentry reliably detects and recognizes objects before they become a hazard.

Sentry offers an intelligent alarm system for both collision avoidance and for approaching objects when at anchor, increasing safety in all conditions. By recognizing and tracking floating persons, Sentry can support SAR efforts and MOB recovery.
