How it works

Sentinel is your cutting-edge underwater security system designed to detect and track potential underwater threats across a wide range of environments. Designed by Wavefront Systems and commercialised by Sonardyne, this innovative technology provides comprehensive protection for your critical infrastructure, naval vessels, ports, and private properties.

With remarkable detection capabilities, Sentinel can identify divers up to 900 metres away and uncrewed underwater vehicles (UUVs) at distances of 1,200 metres. The system is versatile and easy to deploy, whether protecting a commercial harbour, critical national infrastructure, or a private yacht. Its advanced sonar technology can be quickly installed on boats, ports, or coastlines, creating an instant underwater security shield that operates autonomously.

Its user-friendly design sets Sentinel apart. The complex sonar technology is packaged into intuitive software, allowing security personnel without specialised technical expertise to operate the system effectively. For enhanced threat response, an optional accessory called Scylla can broadcast pre-recorded or live audio messages to divers up to 600 metres away, providing an additional layer of deterrence. Whether dealing with busy harbours, shallow waters, or strategic infrastructure sites, Sentinel offers you reliable, real-time monitoring and threat tracking in virtually any marine environment.
