Security & Industry

DolphinEar Hydrophones were originally built for listening to Whales and Dolphins, but they found a widespread application as rugged, weatherproof sensors in a number of industrial and security applications.

SECURITY

DolphinEar hydrophones are equally useful as contact microphones. Below are some of the many applications that our hydrophones have successfully been used for.

Marina and Port Security

Monitor sound activity alongside docks and quays. Any approaching vessels are easily heard before being seen, especially at night. Hear divers, or discharges into the water, etc. One happy customer in the USA , thanks to his DolphinEar hydrophones, was able to apprehend thieves who had been visiting the boats in his marina under cover of darkness. Contact us to discuss your particular needs.

Bay monitoring

DolphinEar hydrophones offer an inexpensive way to monitor protected water environments for unwanted or illegal activity. They are great for conservation areas, natural parks, protection from theft or smuggling, etc..
We are happy to advise you on a suitable set up, including options for monitoring sounds remotely. Contact us to discuss your particular needs.

Perimeter security

DolphinEar hydrophones have been used successfully to check for unauthorised access at boundaries such as gates, fences and walls. They can be attached to the barriers themselves or buried underground. For more details, please contact us below.

Pool & Pond safety

Use a DolphinEar as the underwater equivalent of a baby room monitor! Lets you hear what’s going on above and below the surface. A carefully placed hydrophone can detect footsteps as well as sudden splashes and calls for help. N.B. It should be used as an aid to safety, not a substitute for proper adult supervision.

INDUSTRY

Underwater construction

DolphinEar hydrophones are used to monitor the sites of underwater construction. Typically monitoring and recording begins prior to construction and continues until completion. This provides a permanent record of sound levels to verify compliance with environmental regulations.

Prevent environmental damage

When a hurricane severly damaged a Gulf of Mexico oil platform its legs began to fail due to leaks. Three DolphinEar PRO hydrophones were used to quickly find the leaks. Repairs were successful thereby avoiding catastrophic environmental damage.

Leak detection in plumbing

DolphinEar hydrophones are useful for detecting leaks. It is especially useful for finding a problem deep in a plumbing system without having to excavate large areas.

Infrastructure monitoring

DolphinEar hydrophones are used for a variety of infrastructure monitoring. Whether it be road bridges, overpasses, or other structures the DolphinEar series provides the opportunity to monitor anomalous sounds which could provide early warning of structural failures. This can be done remotely using a cell or mobile phone. Contact us to discuss your specific needs.

Finding leaks in tanks

DolphinEar hydrophones are used for leak detection and have formed the basis for commercial OEM products. They are well suited for use as a general leak detector in swimming pools, underground tanks and pipes.
