Vehicle-mounted security systems play an increasingly important role in modern public safety, perimeter protection, and emergency response. Effective operations require more than mobility alone — clear long-range communication, visual surveillance, and reliable warning capabilities are essential. Beijing RIBRI addresses these needs with the RH20Y, a multifunctional Long Distance Acoustic Device (LDAD) designed for integration with police, security, and military vehicles.
As part of the RIBRI Acoustic & optical product line, the RH20Y combines high-power directional acoustic technology with integrated camera capabilities and optional optical modules, including LED searchlights and laser devices. Designed for vehicle-mounted deployment, the system supports long-range voice broadcasting, targeted acoustic hailing, area surveillance, and emergency command operations.
With a peak sound pressure level of 156 dBA and a maximum specified range of 1,778 meters, the RH20Y provides a powerful acoustic communication solution for demanding operational environments. Its pan-tilt mechanism enables flexible directional coverage, while its ruggedized, IP65-rated design supports deployment in challenging weather and terrain conditions.
