We provide high-performance PCB & PCBA solutions for microphone arrays, acoustic imaging systems, acoustic cameras, and drone detection equipment. Our products are widely used in UAV development, anti-drone systems, and industrial acoustic testing applications.
The LS8118F is a high-performance acoustic localization microphone array designed for acoustic imaging, mechanical anomaly detection, human voice positioning, and drone detection/UAV sound positioning.
Composed of up to 192-channel MEMS array board, MEMS acquisition board, and USB camera, it transmits data via Gigabit UDP/RJ45/USB/Serial to a host PC for real-time processing.
This kit includes a microphone array, a USB camera, and a USB/Gigabit Ethernet acquisition board. It transmits MEMS data to a PC via USB or UDP, and synchronously sends video to the PC via USB. The PC uses algorithms to locate the signal source and overlay it on the video screen.

Radar | RF | Infrared | Acoustic Detection + High-Speed FPV Interception
Urban Low-Altitude Security Solution
| Technology | Core Advantages | Core Disadvantages | Limitations |
|---|---|---|---|
| Radar | Long range; all-weather; accurate positioning | Poor on small/quiet drones; high false alarm; high cost | Not ideal for complex urban & low-altitude scenes |
| RF | Passive detection; locate pilot; multi-target | Failed on silent/autonomous drones; easy interference | Invalid for stealth & non-signal UAVs |
| Infrared | Visual imaging; night vision; small size | Short range; blocked by fog/rain/obstacles | Only good for clear weather & close range |
| Acoustic | 100% passive; anti-EM interference; AI recognition; low cost | Single node limited; needs optimization in loud noise | Adapt to most scenarios; no fatal weakness |
| Tech | Principle | Range | Advantages | Limits |
|---|---|---|---|---|
| Radar | EM echo + Doppler | 3–5 km | All-weather; ranging | Poor for small FPV; high cost |
| RF | 2.4G/5.8G signal capture | 100m–2km | Concealment; locate pilot | Failed on autonomous drones |
| Infrared | Thermal imaging | <2 km | Night use; visual confirm | Weather & obstacle limited |
| Acoustic | Rotor sound + TDOA + AI | 300–500m; network 2–5km | Anti-EM; low cost; high accuracy | Affected by strong wind/noise |
