4-Mic Array with High-Resolution Camera – 180° Voice Pickup – Split-Type Module- GYKS-4M-C180-S

Designed for the next generation of smart audio-visual terminals, the GYKS-4M-C180-S is a professional-grade modular solution combining a high-definition camera with a sophisticated 4-microphone linear array. This split-type design allows for flexible integration into diverse hardware environments, including video conferencing systems, human-computer interaction (HCI) kiosks, and digital signage. Featuring advanced beamforming and 180° directional pickup, it ensures crystal-clear voice capture even in noisy environments.

Product Details (Specifications)

1. Advanced Acoustic Performance

  • 4-Channel MEMS Array: Equipped with four high-performance digital MEMS microphones for superior sensitivity and SNR

  • 180° Directional Pickup: Precise beamforming technology captures sound in a 180° forward arc while effectively shielding background noise and voices outside the target zone.

  • Professional Audio Processing: Integrated algorithms for Echo Cancellation (AEC), Noise Suppression (ANS), Automatic Gain Control (AGC), and Speech Enhancement.

  • Long-Distance Capture: Optimized for high-fidelity pickup at distances of 3 to 10 meters.

2. Flexible Modular Hardware

  • Split-Type Design: Features a dedicated mainboard (100mm x 20mm) and a slim microphone strip board (115mm x 6mm), allowing for versatile placement within your product’s chassis.

  • Customizable Camera: The system supports various camera sensor options (up to 13MP/4K) to meet specific imaging requirements.

  • Integrated USB Hub: The mainboard supports a HUB function to seamlessly connect and power camera devices via a single USB interface.

  • Amplifier Support: Includes support for speaker amplifier output (4Ω 2.5W) for a complete two-way audio solution.

5. Installation & Design Recommendations

To ensure optimal acoustic performance, we recommend:

  • Sealing: Use the provided rubber gaskets to seal the microphone pickup hole, preventing internal structural reverberation.

  • Isolation: The module is designed to be shock-proof; however, maintain sufficient distance between the speakers and microphones to prevent vibration interference.
