Practical Application of Acoustic‑Perception Equipment: Tripod‑Based Portable Gunshot‑Detection Device Enables Rapid Deployment and Sound‑Source Localization
Large gatherings and temporary field defense lack fixed acoustic‑monitoring infrastructure, making it difficult to rapidly locate sudden gunshots or explosive sounds. The portable tripod‑mounted gunshot‑detection system has participated in public‑security drills. Modular hardware allows setup within minutes and delivers accurate recognition and localization of gunshots and explosive pulse sounds under noisy conditions.

In urban public‑security practical drills, the tripod‑mounted portable gunshot acoustic‑detection system has completed full‑process subject validation. The complete modular kit includes multi‑channel acoustic‑array probe, heavy‑load support tripod, external display terminal and portable power‑supply box. Operated by two personnel, the whole system can be assembled and debugged within several minutes. After missions, it can be quickly disassembled for packing and transportation without on‑site pre‑buried cables, perfectly fitting temporary‑mission requirements.
Fitted with multi‑microphone acoustic arrays, the system applies time‑difference‑of‑arrival triangulation algorithms according to sound arrival time differences across microphones. It filters traffic‑flow environmental noise to identify gunshot and explosive pulse signals, calculating real‑time bearing, distance and coordinates of sound sources. Detection results are displayed on the external operation tablet, while original audio files are stored locally as forensic evidence. With an effective detection range up to 1800 m, the whole kit weighs 7.5 kg and supports rapid tripod erection for outdoor temporary missions. It is suitable for public‑security event support, border temporary monitoring and perimeter situational awareness for industrial parks.
