SEA.AI — Machine Vision for Safety & Security at Sea The SEA.AI Sentry is a 360° AI-powered surveillance system delivering complete situational awareness for motor yachts, superyachts, and commercial vessels — detecting, classifying, and tracking every object around your vessel, day and night, from close range to the horizon. IBEX Innovation Award Winner Complete Perimeter Awareness The Watchkeeper scans forward — powerful for passage-making and collision avoidance ahead of the vessel. Sentry goes further. Its motorized pan-and-tilt head rotates a full 360° horizontally and ±20° vertically, watching your stern while you navigate the bow, scanning your beam while you're at the helm, and automatically tracking a person in the water while you maneuver to recover them. For vessels at anchor, operating in busy harbors, or running in areas with traffic from all directions, Sentry's full-circle awareness is the meaningful step up from forward-facing detection. Four Operating Modes Perimeter Surveillance 360° continuous scanning of the water's surface. The moment an object enters a defined safety perimeter, the crew is alerted — critical at anchor, in marinas, and during security-sensitive operations. Collision Avoidance Forward panning with intelligent alarms alerts the crew to potential collision risks with objects in the vessel's path giving maximum reaction time during passage. Target Tracking Lock onto any detected object and Sentry keeps it centered in frame automatically — critical for person-overboard recovery where every second of visual contact matters. Manual Control 8x electronic zoom with precise 360° panning control. Investigate any area or object of interest directly from the helm or bridge display. Detection Ranges Object Type Max Range* Buoy / Person in water Up to 700m Dinghy / RIB / Inflatable Up to 3,000m Motorboat / Sailboat Up to 7,500m Large Vessel To the horizon *Detection range varies with environmental conditions.

Plan Sentry 1-Year $2,022 3-Year $4,940 Lifetime $8,660 Contact us for hardware pricing and bundle options. Installation Sentry is a stand-alone unit that mounts at an elevated position on the vessel for unobstructed 360° rotation. It requires a flat horizontal mounting surface, power cabling, and HDMI connection to your existing display or MFD. SEA.AI recommends installation by a qualified marine electronics technician — plan for a full day on most vessels. Contact us to discuss installation requirements for your specific vessel and integration needs. Frequently Asked Questions What's the difference between Sentry and Watchkeeper?Watchkeeper is a fixed forward-facing system optimised for collision avoidance ahead of the vessel. Sentry rotates a full 360°, providing complete perimeter surveillance in all directions simultaneously. Sentry is the right choice for vessels where threats can come from any direction — at anchor, in congested waters, or for security-critical operations. Can Sentry track multiple objects at the same time?Yes. Sentry detects, classifies, and tracks every contact in the scene simultaneously — giving you a complete operational picture rather than monitoring a single object at a time. How far can Sentry detect a person in the water?Up to 700 meters under favorable environmental conditions — the most critical detection range for person-overboard recovery scenarios where reaction time directly determines outcome. Does Sentry work in complete darkness?Yes. The dual 640x512px LWIR thermal cameras detect heat signatures regardless of ambient light — making Sentry fully effective at night, in fog, and in other low-visibility conditions. Is the third-party API available for commercial bridge integration?Yes. Sentry includes an API for custom integration with existing bridge systems, chart plotters, and commercial electronics stacks. Contact us for API documentation and integration support. What happens if I don't renew the AI licence?Sentry continues to function as a camera system, but AI detection, perimeter alerts, target tracking, and software updates are disabled until the licence is renewed.
