Sentinel detects, tracks and classifies divers and autonomous underwater vehicles (AUVs) approaching a protected asset from any direction and alerts security personnel to the threat. With the ability to identify targets at ranges of up to 1,500 metres*, Sentinel takes reliable, long range underwater intruder detection to a new level and since its introduction, has been used in CNI, vessel and VIP protection duties around the world.

Sentinel is small and lightweight so is quick to deploy from a boat, install in a port or fix along a coastline – providing you with an instant underwater security shield. We’ve engineered all the complexity associated with configuring and operating advanced sonar technology into easy-to-use software meaning that your security personnel don’t need to be sonar experts to use it. In fact, once it’s set up, Sentinel can be left to run autonomously.
