1. A system for detecting a man-overboard event, including:
a plurality of first computing units, each first computing unit including at least one daylight camera detecting light in a visible spectrum and infrared light with a maximum wavelength of 830 nm within a predetermined detecting region and including an infrared light source radiating into the predetermined detection region of the daylight camera,
a second computing unit including a processor and a communicator connected to the plurality of first computing units, wherein each first computing unit, independently of one another, is configured:
to evaluate data sensed by the daylight camera from light reflected in a human visual range from the infrared light source of the respective first computing unit,
to determine whether a man-overboard event is present, based on this data, and
to report a man-overboard event, to the second computing unit, wherein the second computing unit is includes an alarm configured to send an alert and/or of a control command for carrying out of a man-overboard maneuver.
