The Illegal Horn Sounding Enforcement Assistance System is a new “electronic police” solution that utilizes microphone array sound source localization technology to automatically capture images of vehicles illegally sounding their horns. This system precisely locates the source of motor vehicle horn sounds while effectively filtering out environmental interference such as engine noise, braking sounds, and sirens from emergency vehicles, thereby providing authoritative evidence for traffic management.

Millisecond Response Speed: Identifies and directs cameras to sound sources in milliseconds, with a system response time of less than 50ms.
High Angular Resolution: Achieves a precise azimuth resolution of 1°, providing pinpoint accuracy for locating targets in a 360° omnidirectional range.
Advanced Sound Recognition: Built-in AI models can be trained to recognize and differentiate specific audio signatures.
Comprehensive Evidence Retrieval: Automatically retains audio and video footage from several seconds before and after an alarm event, eliminating the need for manual retrospective searching.
