On‑Demand Acoustic‑Warning Capability Realized, Tripod‑Style Portable Gunshot‑Detection Unit Achieves Fast‑Setup Sound‑Source Positioning
Lacking fixed acoustic monitoring, temporary outdoor sites struggle to locate sudden gunshots and blasts. This tripod‑mounted portable gunshot‑detection system, drill‑verified with modular quick‑assembly hardware, identifies and pinpoints gunshot and explosion pulses under noisy conditions.

The tripod‑mounted portable gunshot acoustic‑detection system has finished full‑subject practical verification in public‑security simulation drills. The modular complete kit contains multi‑channel acoustic‑array probe, heavy‑load supporting tripod, external display terminal and portable power‑supply box. Two‑person teams can complete equipment assembly and debugging within several minutes. After mission completion, operators can disassemble and pack up the whole set rapidly, without pre‑laid cables on site, perfectly matching temporary mission requirements.
Equipped with multi‑microphone acoustic array, the system adopts time‑difference‑of‑arrival triangulation algorithm. By analyzing sound arrival time deviation among different microphones, it filters traffic and environmental background noise, picks out gunshot and explosion pulse signals, and calculates real‑time bearing, distance and coordinate information of sound sources. Detection results are displayed on external operation tablet, meanwhile original audio materials are stored locally as forensic evidence. Its effective detecting range reaches up to 1800 m. The total kit weight is 7.5 kg, supporting fast tripod erection for outdoor temporary tasks. It is suitable for public‑security event support, short‑term border monitoring and perimeter situational awareness for industrial parks.
