At CTRLPA, we specialize in "acoustic precaution" for military, police, and emergency application. Our production base meets the requirements for military R&D, production, and testing. We have an experienced industry research team and over 300 independent intellectual property rights. We have mastered the core transducer technology of "acoustic precaution" and developed a series of integrated equipment that are portable, mobile, and platform-based, applicable in maritime, land, and aerial environments for monitoring, warning, and disposal.
The products feature multiple practical functions including strong sound deterrence, directional sound projection, clear voice broadcasting, and long-range amplification, fulfilling the needs for perimeter protection, law enforcement, emergency safety early warning and command for disasters, and last-mile communication to target groups for messaging, alerts, dispersal, and control.
