Applications & Features
The GL-076X Series Avian Bioacoustic Recorder integrates a low-power, high-sampling-rate, high-SNR (Signal-to-Noise Ratio) processor paired with an omnidirectional, low-noise, and high-sensitivity microphone. Complemented by professional-grade amplifiers and filters, it ensures ultra-high-fidelity audio capture. Key advanced features-such as smart acoustic triggering and adjustable-gain amplification-further enhance data precision.
Built with an IP68-rated dust- and waterproof enclosure, the device supports flexible power configurations, including 8 or 16 AA batteries, 6 or 12 rechargeable 18650 lithium-ion batteries, and solar power integration. With storage expandable up to 1 TB via SD card, it guarantees long-term, uninterrupted operation across diverse field scenarios and deployment methodologies. Furthermore, standard 4G cellular and private network connectivity enable seamless, real-time audio transmission to the management platform for automated analysis and processing.

Key Features
Multi-Network 4G Data Transmission (UMSW3): Supports the 700 MHz broadcast spectrum as well as ad-hoc network (mesh) communications.
AI-Powered Avian Species Recognition: The backend server automatically identifies over 1,200 bird species.
Multi-Dimensional Noise Filtering: Advanced audio processing effectively differentiates avian calls from non-bird sound sources, such as human voices, industrial noise, wind, and rain.
Continuous Solar Power: Compatible with a 20W solar panel and battery pack for long-term, uninterrupted field deployment.
