WFSMEM are in service in over 100 countries in diverse applications, including Public Safety, Law Enforcement, Defense, Border and Homeland Security, Critical Infrastructure Protection, Fire Rescue, Emergency Management, Maritime and Port Security, and Wildlife Control and Preservation.

Long Range Acoustic Device for naval anti-piracy operations

Auditory Pain：Causes severe discomfort or temporary hearing loss in the target zone .

High Directivity（8° @ -3dB）：Sound is focused like a beam, Peak Sound Pressure Level (@1m)160dB±2dB

Anti-Piracy：Used by navies to warn and deter pirates approaching ships.

All-Weather：Designed to withstand salt spray, corrosion, and vibration .

Sound transmission range(in Open Space)：4000Meter

Coast guard law enforcement: Chinese coast guard vessels are also equipped with such devices. For instance, on December 9, 2023, the Chinese Coast guard successfully drove away a Philippine official vessel that had illegally intruded in the waters near Huangyan Island in the Nansha Islands by using a remote directional sound wave removal device.

Throughout the world, WFS systems are enhancing security at power plants, dams, embassies, government facilities, water treatment plants and other critical infrastructure. WFS outdoor speakers help communicate issues quickly by communicating over loud background noise and into buildings.

Unlike traditional surveillance systems, WFS provides a vital first response capability missing from observe-only integrated security installations. WFS turns passive surveillance systems into first responders by broadcasting alert tones and audible voice warnings , notifications, and instructions to deter intruders and ensure unauthorized personnel remain at safe distances from critical assets.

Remotely identify and interact with boaters and fishermen, accurately assess situations, and appropriately scale safety and security responses.

Automate perimeter surveillance and enhance power plant and substation security with remotely operated WFS  first response capabilities.

Communicate to vessels not responding to radio calls or failing to follow port and terminal protocols. Enhance first response capabilities at waterside approaches.

Turn passive surveillance systems into remote first responders by broadcasting audible alerts tones, warnings, and instructions to deter intruders and keep unauthorized personnel away from facilities.

WFS systems deliver alert tones and live or recorded voice messages with exceptional clarity for any operational scenario. Optimized to the primary range of hearing, LRAD’s Advanced Driver and Waveguide Technology ensure every broadcast is clearly heard and understood, even above facilities’ background noise.
