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.

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.

Let customers speak for us
from 403 reviewsNomad's were patient and cooperative with our shipping destination hiccup. The Armadillo Horizon 3 meets our expectations. Superior quality fit and finish. A few stand outs include: smooth zippers, noseem blocking mesh screens, mattress as is (no need to use our beloved exped) vestibule screen windows option, attached ladder operation, one person open/close and more. Stormy Wind gust lifted the tent and kicked the ladder back when we were in it.... know now to use included tie down straps in storms. Used 4 nights. Currently no regrets.
The charger you sent me works great. Although I was looking for the charger that is in the pitcher that is why I bought it from this website. Because it showed an image of the same charger I had. The charger you sent me is different. I saw it on other websites for a little cheaper. But went with your sight because it showed me a picture of the charger that I had. Then, you sent me a different charger. I'm still happy the charger works. Thanks.
It took really ling to get here i had my doubts it was coming but yall came through
Purchased two 23zeros 5 years ago, the 87 is for my wife and I and both were mounted on our Ford E350 15 passenger van. We spent 3 months living in them during housing transition and I slept in the 87 for over 500 nights these past two years, for health reasons, after I experienced a stroke at our toxic, built in 1948 rental house. I find the tents extremely well built, comfortable and they've proven their durability. We're in the Pacific NW and the tents have withstood extremely high wind gusting over 60mph (duringall night storms), pouring rain, heavy snow load and summer heat. UV on the rain fly has taken a toll but it's still holding it's own, zero water leaks, ever.
Outstanding product. It was a blast to build, very complete and straightforward assembly, great quality materials. The shipping was a small issue as it comes on a 5’ by 6’ skid and without a forklift home delivery is not an option. All the nuts and bolts were sorted and packed perfectly. The off road tires look great and will be tested. Make sure you have a large torque wrench for the 160 ft-lbs nuts!
My son loves riding dirt bikes and this electric bike is absolutely amazing! He puts his helmet on and rides it all over our farm. The battery holds a charge for the many miles he rides every day and the bike and tires hold up to the rough terrain on the farm! We love this bike!!
Display screen was way too dim during sunlight i think the back break pads were too close to the disk breaks but probably an easy fix. Other than that the torque and power is awesome
Very smooth my son loves it
So far it’s been great. put it together with my 15 yr old son. Drove it once it was a blast. Took me a minute to figure out how to get it to go and change “gears”, but other than that easy breezy so far. I might by another one for my son once we get our house in the country. It’s fast so get yourself a motorcycle helmet:)
Hey folks, Rich here. 62 years young and just got my third e-bike, the G300 Pro. After 40 years in the saddle, I finally found THE ONE. This machine lets me keep up with riders half my age! The handling's so natural it feels like an extension of my body, no fighting the bike, just pure riding joy. It's not just transportation; it's my pride and joy that'll be turning heads at the local meetups. To the team at Happyrunsports: Thank you for helping this old dog ride like he's still got puppy energy!
Assembly wasn’t bad Riding it is a blast. Better than I expected, what a fun bike. Very glad I purchased it
We purchased a storm shelter about a year and a half ago. Fortunately we haven't had to use it but we have it ready. The bench is also a storage area. I think I have half my house in there! Ha. There is plenty of room for snacks, water, a saw, pliers, ear plugs, a small air horn, a whistle, tarp, lock, helmets, and much more.
The people we dealt with were extremely professional. They explained everything they were doing as they installed it and could answer all our questions. I'd give them a 10 if possible.

Just installed. Packaging was phenomenal. Best packing for any package I have ever received. Directions are perfect. Inventory of items was perfect. I installed on the truck rather than the floor then lifting it with four people. By installing it on the truck I needed a second person here and there. I only have one small complaint, but I still give this a 99.99% rating. The complaint might possibly be because I assembled it on the truck instead of the floor. I have a super small gap where the rear section meets the side section at the truck rail. Its pinhole size. I will probably dab it with sealant if it leaks. I will be going to the car wash and testing it out first, but it is so very small it may not even need the sealant. I'm talking literally a pinhole size. I wonder if I assembled on the floor first if it wouldn't even be there. Other than that, everything about this topper is PURE CLASS. Shipping time, packaging, instructions, quality of materials, assembly. I love this topper.
