Acoustic Sensing

Always-On Coastal Defence Ports, Harbours, Shipyards and Naval Bases hold strategic and tactical value, not just for maritime operations but also the country's economy. This is why every major naval base and port deserves a layer of perpetual surveillance for every threat.Zoid's DAS system has the capability to detect and identify threats, and flag these threats to the Indian Navy and Coast Guard while the target is hours away from the shore. It also mitigates with the left-right ambiguity, effectively reducing the response team's reaction time. With the fibre optic cable laid, be it seabed activities, surface level disruptions, marine life or physical cable contact, every activity can be accurately detected thereby enhancing the maritime situational awareness.

Strategic Passage Control Every strategic corridor into the Indian Ocean carries sub-surface transit risk, where unmonitored depths can conceal threats until it's too late. A single cable deployment creates an acoustic tripwire that flags every suspicious activity before it clears the passage, transforming a blind stretch of seabed into a continuously watched perimeter. These corridors are vital for global trade and energy flows. Left unmonitored, these passages become vulnerable to intruders engaged in smuggling, infiltration, and other illicit activities that threaten regional stability. Zoid's Distributed Acoustic Sensing (DAS) systems deliver persistent, real-time underwater awareness, enabling early detection of intruders, smugglers, and unauthorized vessels long before they reach any critical assets. By turning existing fibre infrastructure into a sensing network, Zoid's DAS safeguards the nation's maritime borders while protecting the economic interests that depend on these waters remaining secure.

Dual-Use Environmental Sensing The same cable that secures the corridor also listens to the seabed itself, turning a single deployment into both a security asset and a scientific instrument. With a frequency response spanning 0.001 Hz to 50 kHz, the system captures an extraordinarily wide spectrum of underwater activity, from the faintest seismic tremor to the sharpest pressure anomaly. Every fault-line event, tectonic shift, and subsurface disturbance is recorded continuously, around the clock, without interruption. This same seismic sensing capability gives coastal regions an early-warning layer against undersea earthquakes, enabling faster tsunami alerts and giving authorities critical extra minutes to evacuate vulnerable populations and secure offshore assets. This environmental data stream runs entirely on the existing fibre backbone, meaning there is no additional infrastructure cost, no extra hardware, and no added complexity. The result is a single system that simultaneously strengthens national security, enhances public safety, and contributes valuable geophysical insight, maximizing the return on every meter of cable laid beneath the waves.
