Diver Detection Sonar - Sentinel IDS

Diver Detection Sonar – Sentinel IDS

Sentinel Intruder Detection Sonar (IDS) is the world’s most widely deployed intruder detection sonar, developed to meet the underwater security requirements of private, commercial, government and naval end users.

The system reliably detects, tracks and classifies divers approaching a protected asset from any direction and alerts security personnel to the potential threat. Whether it is protecting a critical infrastructure facility, offshore platform, sea port or superyacht at anchor, Sentinel’s autonomous monitoring capabilities, long range detection and proven low false alarm rates provide a rapidly deployable, 360° underwater security solution. We have been able achieve a detection range of just under 1 kilometre, providing the maximum intruder warning time which equates to around 30 minutes swim time.

Once a threat is detected an optional underwater loudspeaker plays either a pre-recorded message or a massage from the operator via a press to talk microphone. Able to be heard underwater up to 400m away, the message alerts the intruder to the fact that they’ve been detected and helps deter them from carrying out their intended actions. And because threats are constantly evolving, Sonardyne have a team of experienced engineers who will be able to develop the best solution to meet your operational requirements for diver and underwater threat detection.

The small design of the Sentinel sonar head enables a variety of deployment options including light weight alloy frames for short term deployment, seabed mounts, wall or pile mounts, rail mounts or fitted to through hull deployment on large yachts or ships.
