Industry-leading Distributed Acoustic Sensing (DAS) Interrogator, delivering:
• High SNR → Clear signals in complex, noisy environments.
• Large Dynamic Range → Sensing vastly different events, from the footsteps of a cat to a pipeline explosion.
• Battle-Tested Stability → Proven reliability with years of continuous operation in harsh outfield conditions.
Integrated software operating system, which is:
• Comprehensive & Intuitive → Signal recovery, analysis metrics, real time API, full recording & playback, modern graphics UI … all combined and offered to you, in a clean, clear and intuitive way.
• Easy to Use → A single click to start the whole sensing machine; default settings are already good for most scenarios.
• Extensible → Need a new specific feature for your project? Just tell us. In most cases, we deliver it for you in days.
Intelligent AI system, enabling:
• State-of-the-Art Detection Accuracy → Powered by modern AI architectures, validated in our own test fields, delivering outstanding event detection performance.
• Quick Adaptation to Your Use Case → Models can be efficiently trained to your specific scenarios to achieve optimal performance in real-world deployment.
• Seamless Integration to DAS → All models are plug-and-play, minimizing integration effort and accelerating time-to-value.
• AI is essential for DAS applications, and this is where we excel.
For nearly all real-world DAS scenarios, simply measuring vibration signals is not enough — it’s critical to understand what those signals truly represent. This is where AI delivers the most value.
Our dedicated AI team consists of engineers from top-tier universities and research labs, with backgrounds in computer science, mathematics, and automation. We understand AI in depth, and we bring this expertise directly into your DAS system.
A wide range of signal analysis algorithms and pre-trained AI models are already built-in, ready for immediate use. If you require customization, our engineers are always available to adapt existing models or design new ones specifically for your use case.
• The DAS system we offer is easy to use and deploy.
With only 5.3kg in total weight, and dimensions that can well be suited to a flight cabin luggage, The DAS system we offer is currently the most compact and portable in market.
This gives your team maximum flexibility for field testing, even in remote locations, while saving significant time and labor costs in transportation and deployment.
• Good cost-effectiveness.
While reducing purchase price is not our ultimate goal (ensuring the success of your project always comes first), we maintain a competitive cost structure, resulting in an overall high cost-effectiveness.
