OSCAR will generally detect all objects on and above the water surface, no matter what the object is made of (e.g., wood, steel, plastic, organic,…).
OSCAR can see up to the horizon, but the detection range is deliberately limited (depending on the model) in order not to detect too many far away objects, which are (at that point in time) not hazardous for navigation.
OSCAR not only detects but also classifies objects. This means that OSCAR knows what an object actually is: a buoy, a container, a sailing boat, a motorboat, a large ship. If OSCAR is not sure, it will classify an “unknown object”.
Within the detection range, OSCAR will detect all large enough objects in its field of view.
In fair weather conditions, day or night, you can expect to typically detect (and classify):
– a large-sized object (e.g. yacht, fishing vessel, cargo) in ~1000m,
– a medium-sized object (e.g. RIB, channel marker) in ~250m,
– a small-sized object (e.g. mooring buoy) in ~100m
(Guidance estimates, based on OSCAR 320 models.)
The OSCAR 640 models equipped with 640×512 pixel cameras perform better than described above and are more accurate / reliable in detection / classification especially in changing weather conditions.
For higher boat speeds (>15kn), we recommend the higher resolution cameras.
Yes, OSCAR consists of thermal and color cameras and can therefore see during the night. Even in bad weather situations the thermal cameras will be able to perform much better than the human eye. Taking into account that a crew is usually helming, navigating or just busy with other things – OSCAR will continue to keep an eye and act as the “barrelman” on top of the mast, alarming when a potential hazard appears.
OSCAR has an in-built IMU (Inertial Measurement Unit). The IMU helps OSCAR to know in which direction and with which acceleration the cameras and the boat are moving. As a second point of reference for image stabilisation and movement compensation, OSCAR uses AI-based horizon detection. This is the reason why OSCAR also works in bad sea states. Since OSCAR is mounted at a minimum of 7m above the surface (on sailing vessels OSCAR is mounted on the mast top), it can see over the wave crests. Waves will generally influence the boat’s pitching and rolling, and the crew will have a hard time to identify even close objects. As soon as the boat drops into a wave trough, it is typically impossible to see behind the next wave. The mounting height will already make OSCAR a lot more reliable than what a crewmember can see.
In short: a colour camera.
In detail: The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors: red, green, and blue.
Radar detect bigger objects like ships and land over high distances in all weather conditions.
Radar detection rate drops with the height of waves since salt water reflects radar waves.
Oscar sees small objects drifting in the water as well as small leisure crafts such as SUPs, kayaks, dinghies, small wooden fishing boats, etc…
Oscar´s AI will detect objects with position, speed and course information up to 600m / 1000m (depending on the models) and will detect objects and display bearing information and distance estimation up to the horizon.
Being an optical system, Oscar´s performance degrades in fog and rain. Oscar and Radar are therefore complementary systems with different benefits and limitations.
AIS displays information from vessels equipped with an AIS transceiver. AIS is mandatory for ships with more than 300 gross registered tons. Many smaller ships are not equipped with AIS transceivers.
Similar to AIS, OSCAR displays information on detected objects, such as speed, direction, CPA, TCPA, object type.
In light rain, OSCAR will be able to detect objects but its detection range will be reduced. In very heavy rain, objects cannot be detected anymore. In the fog, a thermal camera can see 3x further than the human eye. OSCAR has the same physical limits as all optical sensors.

This hugely depends on which cables one installs. On cruisers / racers and all other boats we usually mount cables with a weight of 52 grams / metre. Since there are 2 cables needed, this means that for a 20 metres mast, the total cable weight would be ~2 kilograms. (104g/m for both cables))
For racing application or on demand, we can also provide cables with ~80g/m in total for the 2 cables.
The vision unit should be attached to the highest point of the boat. In sailing boats this will be the mast top with no obstructions in front (e.g. windvane, nav lights or halyards in the way). On motor yachts, it should be as high as possible as well and the minimum mounting height should be 8m above the waterline.
OSCAR needs to see the horizon as a reference point. Once you set up OSCAR and start the app on your smartphone, tablet, onboard computer or MFD it will ask you to calibrate. There is an assistant that will tell you step by step how to calibrate and find the optimum angle for the vision unit. 3 parameters need to be entered during setup:
It is important to mount the processing unit in a dry environment and in a vertical position with at least 100 mm clearance on top and 150 mm below bottom to other devices (heat convection). Make sure to keep it clear of any Wi-Fi or GPS antennas as they might interfere.
Yes, as long as the information is available on the NMEA2000 network.
No, the data cable is shielded and the electromagnetic compatibility complies with EU norms.
OSCAR’s app does not need permanent internet access.
We provide regular updates for your system and app which the user needs to download first to install it on the system.
Yes, OSCARs vision unit is waterproof (IP67) and has been tested in extreme conditions to ensure watertightness, temperature, shock, vibration, and salt water resistance. The lenses of the cameras carry a special coating for protection against the most extreme weather conditions and dirt.
Yes, all OSCAR products can withstand at least forces of 10g. This is validated during durability tests with more than a 1 million cycles.
During longer periods or summers without rain, it might be necessary to clean the RGB lens about every 2 to 3 months.
Yes. It needs to be integrated into the Boat LAN /WiFi for communication with the User Interface (PC, Laptop, Tablet or MFD).
On Oscar Advanced and OSCAR Racing Series, 3 IP addresses are configured.
OSCAR ONE does not need any IP configuration.
An interface to selected MFDs / chart plotters is available.
Please get in touch with us to check compatibility.
4 users can connect simultaneously without speed loss of the application. Above this number application load and refresh time could be slightly impacted.
Yes. OSCAR can be connected to the boat bus to receive (e.g., speed, heading, GPS position) and send (e.g., objects found, alarms, autopilot commands) information.
OSCAR will also work without being connected to the boat bus. In this case, only relative (and not absolute) values (speed, course) will be displayed.
This is a feature we might offer in the future.
