Harbor fence

A system for protecting an asset that abuts a body of water, the system comprising:

• a flotation component that maintains the system at essentially a surface of the body of water, wherein the flotation component comprises a plurality of spars and wherein each spar is connected to an adjacent spar with at least one connecting line;
• a first sensor array comprising a first sensor element and a second sensor element, the first sensor element located at a first location along the flotation component and the second sensor element located at a second position along the flotation component, wherein each sensor element comprises an immersion sensor pair and an acceleration-sensitive sensor and detects whether an intruder is cutting, submerging, or lifting a boom line in the proximity of said each sensor element;
• a plurality of control modules, wherein the plurality of control modules comprises a first control module, wherein the first control module communicates with the first sensor array over a first wireless channel and that receives a first signal from the first sensor element and a second signal from the second sensor element, and wherein each signal is indicative whether a corresponding sensor detects the intruder passing through the system at a corresponding location;
• a notification component comprising a series of lights;
• a control unit that controls a sequencing of the series of lights, that connects to the first control module through a second wireless communications channel, that selects the first control module from the plurality of control modules, and that receives an indication whether the intruder is detected by the first control module, wherein the control unit provides a security status.
